Khloe Kardashian’s Quotes About Weight Loss and Fitness – Life&Style Weekly

Posted: April 9, 2021 at 1:44 am

In need of some fitness inspo? Khlo Kardashians most inspirational quotes about weight loss and working out prove how hard the Keeping Up With the Kardashians star has worked over the years.

The Revenge Body host found solace in fitness amid her divorce from ex-husband Lamar Odom. Khlo split from former NBA player in 2013, but they werent legally divorced until 2016.

For me, I was overweight I was unhealthy for a lot of my life, the Good American founder explained on host Jay Shettys On Purpose podcast in October 2019. I started going to the gym during my divorce, like a significant and consistent amount for my mental [health]. I needed a release and I needed to feel strong and I just needed to get rid of all these thoughts. And, I wanted to be alone and the only place to really be alone was to be on an elliptical with headphones in my ears and kinda just vibing out.

While using the gym as an escape, her body began to transform. As a side effect, I started losing weight and I was like, Oh, I kinda like this. Then, losing weight just became some sort of competitive weird streak in me that was like, I want to see if I can get arm muscles, she explained. It started as that, but it was never my goal. It was never: I want to look good in a bikini. It was never my goal. I just wanted to feel good mentally. And, I think when you start putting yourself first, you start feeling so much better.

The Strong Looks Better Naked author gave birth to her daughter, True Thompson, in April 2018 with boyfriend Tristan Thompson, which gave her a drive to stay fit.

Ive always been good with kids, but she gives you a different kind of patience. And, when you feel like youre exhausted and you cant go on with your day when youre around your own child, you get this surge of energy, KoKo noted about the sweet girl. Youre just like, Oh, Ive got to keep going. You just figure it out. So she just gives me, I think, more of a drive to stay fit and stay healthy because I want to be an active mom with her. I want to be here as long as I can. I would say its a different type of patience, its softer patience.

Combat sports athletes are using a deadly weight gain hack to game the weight classes – Salon

Posted: April 9, 2021 at 1:44 am

On the eve of a recent mixed martial arts (MMA) fight, Julija Stoliarenko walked up to the scale on the stage so that Nevada state officials could record her weight. Weigh-ins are always a fraught event; in Ultimate Fighting Championship (UFC) fights, just as in boxing, fighters must adhere to a very precise weight range in order to qualify. Stoliarenko was a UFC bantamweight fighter, which meant she needed to weigh-in between 126 and 135 pounds no more, no less.

While on the scale, Stoliarenko wobbled and lost her balance, then staggered backward and collapsed against the UFC backdrop. Security personnel rushed to aid her. After several minutes, she tried again and collapsed backwards to the floor. The bout was canceled because of her health complications; specifically, Stoliarenko was knocked out by a dangerous health practice known as weight-cutting, which involves rapidly losing weight in the weeks before a weigh-in and then rapidly gaining it back in the twenty-four hours before a fight.

If you think that sounds risky, you're absolutely right. So why would health-conscious fighters, who rely on their body for their career,willingly do such a thing? And how did it become so common?

Understanding that requires first understanding how weight classes work. In wrestling and combat sports such as boxing and MMA, weight classes were devised to match similarly sized opponents. Athletes are required to weigh-in before competition to ensure they are within the agreed-upon weight range. If opponents are not matched fairly, the heavier opponent will have a significant advantage when it come to generating power as well as pinning their opponent against the ropes, cage, or mat.

But there's potentialfor a loophole here. Because weigh-ins generally occur one day before competition, it is possible to game the system if you can somehow artificially lose weight say, losing water weight, while retaining muscle mass and then gain it back after weigh-in. Doing this successfully makes it possible for fighters to gain a weight advantage against their opponents, as they show up to the match weighing much more than they did during weigh-in.

This can lead not only to an unfair fight, but also a dangerous one though often, both fighters are weight-cutting, as it can confer a significant advantage if done successfully.

Here's how it works. Weight-cutting starts off essentially as a seemingly normal weight-loss diet: fighters eat healthy and work to burn more calories than they consume. Ideally, this allows weight loss from burning muscle and fat. Then, as the weigh-in deadline looms closer, athletes resort to losing weight by dehydration. By getting rid of as much water as possible, they can shed the extra few pounds they need to pass the weigh-in,and then gain it back by rehydrating. Usually, that means chugging a bunch of Gatorade as soon as they step off the scale; in extreme circumstances, they may have a friend waiting with an IV bagjust off-stage.

Methods for this second, dehydrating phase of weight-cutting are unhealthy, and include drinking minimal fluids; saunas; plastic workout suits; "pre-loading" with excessive water; and taking prescription diuretics to lose water by excessive urination. All of these methods aim to remove water from the body as quickly as possible and in large enough quantities that pounds are lost in a manner of days or hours. Some fighters even chew gum to help spit out more saliva making every last drop of water loss count.

Veteran athletes often have weight-cutting down to a science, knowing how long they need to cut a specific number of pounds. For example, a high-level wrestler will know how many minutes they need to spend in the sauna to reach a given weight. This might limit the outward appearance of dehydration or minimally impact their performance since they are less dehydrated at each step. But internally, their organs may be on the verge of failure.

Less experienced athletes often struggle with weight-cutting, and in some cases may hire nutrition coaches just to help them shed pounds quickly. That struggle is known as a "hard cut," and is often blamed for a fighter not making weight or suffering consequences of extreme weight loss.

There is no question that extreme weight-cutting is unsafe. Documented dangers of extreme weight-cutting vary and include changes in core body temperature, nervous system dysfunction, electrolyte imbalances, and cardiovascular strain.

Weight cutting and its effects have yet to be fully documented at the professional level, but in 2013 and 2016, two MMA athletes lost their lives while cutting weight. Leonardo Souza was found collapsed in a sauna after suffering a fatal cerebrovascular event. He took a fight on short notice and was attempting to lose 33 pounds in one week. Likewise, there has been a rise in the number of combatants hospitalized for medical complications in the days leading up to a weigh-in.

In 1996, a series of NCAA weight-cutting related deaths in wrestling within weeks of each other led the organization to re-evaluate weight-cutting practices among their athletes.The NCAA moved weigh-ins from the day before an event to the day of the event. They also recommended instituting what they called a "1.5% rule," which states that athletes should lose not more than 1.5% of body weight per week. For example, a 165-pound student-athlete trying to make a 157-pound weight class should lose no more than two pounds (i.e. 1.2% of total body weight) per week. This helps to minimize the degree of dehydration.

In professional events like boxing and MMA, as well as many international wrestling events, weigh-ins still occur one or two days prior to the competition. Hence, weight-cutting is still common among these fighters, as research has found. Unpublished studies of professional MMA fighters in California showed that most fighters do not weigh within the agreed-upon fight weight-class the night of the bout. Most walk into the cage one or two weight-classes above the contracted weight class.

One study of professional MMA athletes looked at athlete's bodies at weigh-in and then again 22 hours later, just before the bout. In this study, MMA athletes gained an average of 7.5 lbs 4.4% of their body weight! in the 22 hours before the fight. Among those studied, at least one athlete gained back 22 pounds (10% of their body weight) in that day. The study also found that, at fight-time, 39% of the fighters were either significantly or seriously dehydrated as measured by urine specific gravity.

The dangers of weight-cuttinghave led to calls for weigh-in reforms, both from the media and from professional medical organizations. Indeed, in 2016, a call to alarm over weight-cutting was published in the British Journal of Sports Medicine.California state athletic commissioner Andy Foster, who oversees all of combat sports in his state, has called weight-cutting " the biggest problem in combat sports."Groups such as the American College of Sports Medicineand the Association of Ringside Physicianshave issued recommendations to end excessive dehydration as a weight-cutting tool.

Yet, despite the known medical dangers, money always plays a part in hindering reform. If fighters agree upon a weight-class title bout and the fighters do not make weight, then fans and promoters lose out on a much-hyped title fight.To wit: just a few months ago, a Bellator main event had to be changed at the last minute when one fighter failed to make weight.

Tickets,pay-per-views and sponsorshipscome at a price. Losing a title fight due to a weight issue is like paying to see a movie and then finding out the main actor bailed at the last minute. Professional sports organizations obviously try to avoid these situations, which may be why they tolerate or turn a blind eye to weight-cutting.

In the United States, there is no federal regulatory body that oversees professional combat sports; rather, states have their own athletic commissions who oversee and enforce the rules for boxing and MMA. There have been some proposals for standardization and enforcement of weight-cutting regulations. Some states that see a lot of fights such as California and Nevada have more extensive medical and regulatory bodies in place and the budgets to keep them better funded. In 2019, California passed a measure to curb extreme weight cutting. Fighters weighing above 15% of their contracted limit on the day of the fight would no longer be allowed to compete. Other states have less money and personnel to enforce stricter health and safety measures.

Mixed martial arts is one of the world's fastest growing sports, but lack of federal oversight and inconsistent enforcement of weight-cutting protocols continue to put fighters at a deadly risk if they can't safely make weight. There have been calls for fighters to form their own union, and perhaps better medical care might be part of that package. Unfortunately, at this stage, it is usually up to the fighter and their camp of trainers to regulate what methods they use to cut weight and how fast they do it. When a big name say, UFC, Bellator, or even the Olympics comes calling, it can be hard for fighters to resist trying to gain every competitive advantage possible, even those that are dangerous. After all, athletes are trained to push harder, faster, stronger; they may see their weight-cutting as an opponent like any other, one they can outwit or out-muscle. But if we like watching combat sports as spectators, we should speak out about keeping athletes healthy.

26 Weight Loss Tips That Are Actually Evidence-Based – Healthline

Posted: April 9, 2021 at 1:44 am

The weight loss industry is full of myths.

People are often advised to do all sorts of crazy things, most of which have no evidence behind them.

However, over the years, scientists have found a number of strategies that seem to be effective.

Here are 26 weight loss tips that are actually evidence-based.

It is often claimed that drinking water can help with weight loss and thats true.

Drinking water can boost metabolism by 2430% over a period of 11.5 hours, helping you burn off a few more calories (1, 2).

One study showed that drinking a half-liter (17 ounces) of water about half an hour before meals helped dieters eat fewer calories and lose 44% more weight, compared to those who didnt drink the water (3).

Eating whole eggs can have all sorts of benefits, including helping you lose weight.

Studies show that replacing a grain-based breakfast with eggs can help you eat fewer calories for the next 36 hours as well as lose more weight and body fat (4, 5).

If you dont eat eggs, thats fine. Any source of quality protein for breakfast should do the trick.

Coffee has been unfairly demonized. Quality coffee is loaded with antioxidants and can have numerous health benefits.

Studies show that the caffeine in coffee can boost metabolism by 311% and increase fat burning by up to 1029% (6, 7, 8).

Just make sure not to add a bunch of sugar or other high-calorie ingredients to your coffee. That will completely negate any benefits.

You can shop for coffee at your local grocery store, as well as online.

Like coffee, green tea also has many benefits, one of them being weight loss.

Though green tea contains small amounts of caffeine, it is loaded with powerful antioxidants called catechins, which are believed to work synergistically with caffeine to enhance fat burning (9, 10).

Although the evidence is mixed, many studies show that green tea (either as a beverage or a green tea extract supplement) can help you lose weight (11, 12).

Green tea is available at most pharmacies, health stores, and grocery stores, as well as online.

Intermittent fasting is a popular eating pattern in which people cycle between periods of fasting and eating.

Short-term studies suggest intermittent fasting is as effective for weight loss as continuous calorie restriction (13).

Additionally, it may reduce the loss of muscle mass typically associated with low-calorie diets. However, higher-quality studies are needed before any stronger claims can be made (14).

A fiber called glucomannan has been linked to weight loss in several studies.

This type of fiber absorbs water and sits in your gut for a while, making you feel more full and helping you eat fewer calories (15).

Studies show that people who supplement with glucomannan lose a bit more weight than those who dont (16).

You can find glucomannan supplements not only at vitamin shops and pharmacies but also online.

Added sugar is one of the worst ingredients in the modern diet. Most people consume way too much.

Studies show that sugar (and high-fructose corn syrup) consumption is strongly associated with an increased risk of obesity, as well as conditions including type 2 diabetes and heart disease (17, 18, 19).

If you want to lose weight, cut back on added sugar. Just make sure to read labels, because even so-called health foods can be loaded with sugar.

Refined carbohydrates include sugar and grains that have been stripped of their fibrous, nutritious parts. These include white bread and pasta.

Studies show that refined carbs can spike blood sugar rapidly, leading to hunger, cravings and increased food intake a few hours later. Eating refined carbs is strongly linked to obesity (20, 21, 22).

If youre going to eat carbs, make sure to eat them with their natural fiber.

If you want to get all the benefits of carb restriction, then consider going all the way and committing to a low-carb diet.

Numerous studies show that such a regimen can help you lose 23 times as much weight as a standard low-fat diet while also improving your health (23, 24, 25).

Using smaller plates has been shown to help some people automatically eat fewer calories (26).

However, the plate-size effect doesnt appear to affect everyone. Those who are overweight seem to be more affected (27, 28).

Portion control simply eating less or counting calories can be very useful, for obvious reasons (29).

Some studies show that keeping a food diary or taking pictures of your meals can help you lose weight (30, 31).

Anything that increases your awareness of what you are eating is likely to be beneficial.

Keeping healthy food nearby can help prevent you from eating something unhealthy if you become excessively hungry.

Snacks that are easily portable and simple to prepare include whole fruits, nuts, baby carrots, yogurt and hard-boiled eggs.

Taking probiotic supplements containing bacteria of the Lactobacillus subfamily have been shown to reduce fat mass (32, 33).

However, the same doesnt apply to all Lactobacillus species. Some studies have linked L. acidophilus with weight gain (34).

You can shop for probiotic supplements at many grocery stores, as well as online.

Chili peppers contain capsaicin, a spicy compound that can boost metabolism and reduce your appetite slightly (35, 36).

However, people may develop tolerance to the effects of capsaicin over time, which may limit its long-term effectiveness (37).

Doing aerobic exercise (cardio) is an excellent way to burn calories and improve your physical and mental health.

It appears to be particularly effective for losing belly fat, the unhealthy fat that tends to build up around your organs and cause metabolic disease (38, 39).

One of the worst side effects of dieting is that it tends to cause muscle loss and metabolic slowdown, often referred to as starvation mode (40, 41).

The best way to prevent this is to do some sort of resistance exercise such as lifting weights. Studies show that weight lifting can help keep your metabolism high and prevent you from losing precious muscle mass (42, 43).

Of course, its important not just to lose fat you also want to build muscle. Resistance exercise is critical for a toned body.

Fiber is often recommended for weight loss.

Although the evidence is mixed, some studies show that fiber (especially viscous fiber) can increase satiety and help you control your weight over the long term (44, 45).

Vegetables and fruits have several properties that make them effective for weight loss.

They contain few calories but a lot of fiber. Their high water content gives them low energy density, making them very filling.

Studies show that people who eat vegetables and fruits tend to weigh less (46).

These foods are also very nutritious, so eating them is important for your health.

Sleep is highly underrated but may be just as important as eating healthy and exercising.

Studies show that poor sleep is one of the strongest risk factors for obesity, as its linked to an 89% increased risk of obesity in children and 55% in adults (47).

A recent study found that 19.9% of people in North America and Europe fulfill the criteria for food addiction (48).

If you experience overpowering cravings and cant seem to curb your eating no matter how hard you try, you may suffer from addiction.

In this case, seek professional help. Trying to lose weight without first combating food addiction is next to impossible.

Protein is the single most important nutrient for losing weight.

Eating a high-protein diet has been shown to boost metabolism by 80100 calories per day while shaving 441 calories per day off your diet (49, 50, 51).

One study also showed that eating 25% of your daily calories as protein reduced obsessive thoughts about food by 60% while cutting desire for late-night snacking in half (52).

Simply adding protein to your diet is one of the easiest and most effective ways to lose weight.

If you struggle to get enough protein in your diet, taking a supplement such as protein powder can help.

One study showed that replacing some of your calories with whey protein can cause weight loss of about 8 pounds over time while increasing muscle mass (53).

Whey protein is available at most health stores and online.

Sugar is bad, but sugar in liquid form is even worse. Studies show that calories from liquid sugar may be the single most fattening aspect of the modern diet (54).

For example, one study showed that sugar-sweetened beverages are linked to a 60% increased risk of obesity in children for each daily serving (55).

Keep in mind that this applies to fruit juice as well, which contains a similar amount of sugar as a soft drink like Coke (56).

Eat whole fruit, but limit or avoid fruit juice altogether.

One of the biggest problems with diets is that they rarely work in the long term.

If anything, people who diet tend to gain more weight over time, and studies show that dieting is a consistent predictor of future weight gain (57).

Instead of going on a diet, aim to become a healthier, happier and fitter person. Focus on nourishing your body instead of depriving it.

Weight loss should then follow naturally.

Your brain may take a while to register that youve had enough to eat. Some studies show that chewing more slowly can help you eat fewer calories and increase the production of hormones linked to weight loss (58, 59).

Also consider chewing your food more thoroughly. Studies show that increased chewing may reduce calorie intake at a meal (60).

These practices are a component of mindful eating, which aims to help you slow down your food intake and pay attention to each bite.

Numerous techniques can aid your weight loss goals.

Some of the above tips are purely dietary, involving eating more protein or cutting back on added sugar.

Others such as improving sleep quality or adding a workout routine are more lifestyle-based. For example, chewing more slowly is one step you can take to institute mindful eating.

If you implement a handful of these tips, youll be well on your way to your weight loss goals.

26 Weight Loss Tips That Are Actually Evidence-Based - Healthline

A beginner’s guide to a plant-based diet and how it can benefit your health – Insider

Posted: February 17, 2021 at 10:55 am

Whether for health, ethical, environmental, or spiritual reasons, plant-based diets continue to grow in popularity, with nearly 10 million Americans adopting one. Here's what you need to know about plant-based diets and their potential risks and benefits.

A plant-based diet consists of mostly plant-based food sources like fruits, vegetables, beans, legumes, whole grains, nuts, seeds, and oils. However, some plant-based diets still include small amounts of animal products.

"A key point for those contemplating a plant-based diet is that it does not have to be an all or nothing proposition. Each change one is able to make whether it's eliminating some type of animal-based food or just reducing its frequency can have significant health impact when done the right way," says Mindy Haar, RDN, a clinical associate professor and chair of Interdisciplinary Health Sciences at New York Institute of Technology.

Plant-based diets require a diverse variety of foods in order to meet nutrient needs.

"Vegans who consume no animal products at all may be at risk for vitamin B12 deficiency and may consider supplementing this vitamin. Those who eliminate dairy products can still get enough calcium from fortified plant-based milks, calcium-fortified orange juice, and tofu," Haar says.

You should avoid or limit consumption of these foods:

Following a plant-based diet can be beneficial to both your health and the health of the environment.

1. Plant-based diets can help you lose weight

Research has found following a plant-based diet can decrease obesity risk and aid in weight loss.

Animal foods including meat and dairy products are often high in saturated fat and low in fiber. Research indicates consuming foods high in saturated fat is linked to obesity and heart disease. Meanwhile, high fiber foods like vegetables can help with weight loss.

"When one moves to a more plant-based diet, the animal-based foods are typically replaced with legumes, whole grains, and more fruits and vegetables. As these foods are filling, higher in fiber and nutrients, and lower in fat there is potentially reduced calorie intake leading to weight loss," Haar says.

What the research says: A small 2018 study found overweight people who followed a plant-based vegan diet for 16 weeks saw an improvement in body weight, fat mass, and insulin resistance markers compared to a control group. The decrease in fat was associated with an increased intake of plant protein, and decreased intake of animal protein.

2. Plant-based diets can reduce your risk of diabetes

Research has found plant-based diets are effective in reducing the risk of type 2 diabetes.

A large 2009 study found the prevalence of prediabetes and type 2 diabetes is significantly lower among people following plant-based eating patterns compared with those who eat meat.

The prevalence of type 2 diabetes decreased with a reduction in animal products: from 7.6% in non-vegetarians, 6.1% in semi-vegetarians, 4.8% in pesco-vegetarians, 3.2% in lacto-ovo vegetarians, and 2.9% in vegans.

Plant-based diets are typically full of high-fiber foods like vegetables, legumes, and fruits which Haar says can reduce glucose intolerance the high blood glucose levels seen in pre-diabetes and type 2 diabetes.

3. Plant-based diets can reduce your risk of heart disease

Coronary heart disease, the leading cause of death in the US, occurs when plaque builds up in the walls of arteries.

"Animal meats and processed snacks are notorious for being high in saturated fat, sodium, and cholesterol which can cause plaque buildup in arteries," says Kelly Springer, RD, the founder of nutrition program Kelly's Choice.

However, not all plant-based diets are created equal. A large 2017 study found those who followed a plant-based diet rich in "healthier" plant-based foods like whole grains, fruits, vegetables, nuts, and legumes and low in "less healthy" plant-based foods like refined grains, potatoes, sweetened beverages, and desserts had lower rates of coronary heart disease (CHD).

Those who followed plant-based diets that emphasized "less healthy" plant foods experienced a significantly increased risk for CHD.

Plant-based diets are beneficial to all people, but experts warn that it's important to make sure you're consuming enough nutrients that are more commonly found in animal products like protein, vitamin D, and vitamin B12.

To make up for these discrepancies, people following plant-based diets should integrate fortified foods like almond milk or talk to their doctor about taking a multivitamin supplement.

Additionally, those recovering from eating disorders should avoid following a plant-based diet while still in the recovery process.

"Plant-based diets are restrictive and can limit the recovery process of someone learning that all foods fit in a healthy and balanced diet," Springer says.

A 2020 survey found 48% of people choose to follow a plant-based diet for environmental reasons, an increase of 17% since 2018.

Avoiding meat and dairy products is one of the most substantial ways to reduce your carbon footprint. Livestock production is responsible for 14.5% of greenhouse gas emissions the gases that trap heat in the atmosphere and contribute to climate change.

Animal products, particularly meat, are also significantly more resource-intensive to produce than plant-based foods. One pound of beef requires between 2,000 and 8,000 gallons of water to produce, while one pound of tofu requires 302 gallons. Therefore, cutting back on animal-based food can help prevent further water scarcity.

Plant-based diets are beneficial to most people and can help prevent chronic diseases, but changing your diet doesn't have to be an all or nothing operation. Integrating more fruits, whole grains, and vegetables into your diet while decreasing your consumption of animal products is a low-risk way to improve your overall health and reduce your carbon footprint.

Massive National Health Study Looks to Tailor Your Diet to Your Genetic Makeup – Singularity Hub

Posted: February 17, 2021 at 10:55 am

Like taxes and death, nutrition is something we cant escape. Eating should be easy. Yet its also massively confusing, prone to misinformation, and utterly personal.

Take competitive eaters who regularly chow down on thousands of calories without gaining weight. Compare them to people who pack on pounds just looking at a French fry. Or compare people who can tolerate any food to those who are sensitive or allergic to entire food groups. Or people who thrive on a high-fat diet like keto, to unfortunate souls whowith the same dietneed to stay close to the bathroom.

You get the idea: no one diet fits all. Yet nutrition science has long relied on averages to make dietary recommendations. From the 80s fat is bad paradigm to todays sugar is horrible trend, its always been easy to vilify one food component, without digging into how each of us interact with the foodstuff we eat.

Now, thanks to a massive new project led by the National Institutes of Health (NIH), nutrition science is about to get the precision treatment. With a price tag of $156 million, the five-year-long study will examine how 10,000 Americans process food. The program, Nutrition for Precision Health, isnt pulling punches. Each person will be given a highly controlled diet to reduce variability. Theyll then be thoroughly monitored for everything from blood sugar levels to their genes, proteins, and gut microbiome composition. Using the massive dataset, the program can then develop AI-based algorithms to predict individual responses to foods and diets.

If successful, we may soon have a scientifically-proven way of optimizing our diet and health based on our genes and gut microbes. While the culinary astronauts among us may cringe at the idea, for those with metabolic disorders or food intolerances, the algorithms are a powerful tool to aid nutritionists in prescribing diets to those who seek help.

Nutrition science has had a bit of a fuzzy reputation. But its not through any fault of its own. The field faces two major unenviable challenges: one, the results are the average of entire study populations, and two, humans hate sticking to a strict diet for long enough to get consistent results. Ever tried a 14-day diet? Now imagine doing it for five years.

As Paul Coates, vice president of the American Society of Nutrition puts it, were all free-range eaters, which mucks up the resulting data.

Thats not to say classic nutrition science hasnt had major wins. Take the Framingham Heart Study, which launched in 1948 with over 5,000 people to better understand heart and blood vessel health. The study was a first population-level triumph in linking diet to cardiovascular diseases, which remains one of the top killers today.

But to NIHs director Dr. Francis Collins, its high time to bring nutrition science into the 21st century. In May 2020, the agency released a 10-year plan to dig into the nitty-gritty of nutrition, tackling the what, when, why, and how to eat to optimize health and reduce chronic health plagues such as diabetes, obesity, and heart disease.

Its looking to be a wild ride. For example, the ambitious effort doesnt just focus on the gut. Thanks to new research showing intimate connection between the gut and the braindubbed the gut-brain connectionthe plan also embraces neuroscience as a component. Given the link between longevity and diet, itll also study the role of nutrition across our lifespans, or even how to use food as medicine.

And underlying all these fundamental questions? Personalization: how each of us responds to the food we eat.

The new program will be housed under the NIHs flagship health project, All of Us. The research program aims to recruit one million people under its banner to build a Google Earth-style database of biology, health, lifestyle, and disease. The key is individuality: forget average treatments, personalization is the future.

To Dr. Griffin Rodgers, director of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDKK), now is the perfect time to explore precision nutrition. In a presentation last September, he laid out why. Were beginning to understand how the microbiome influences health. We can rapidly perform multi-omics studiesthat is, look at a persons whole system of genes, proteins, and metabolism. AI and machine learning make it easier to analyze these massive datasets. Finally, digital health tech, offered through smartphones or smartwatches, makes everyday health tracking simple and affordable.

The project is planned in three stages. Roughly 10,000 volunteers from All of Us will wear various monitorssimilar to Fitbitsto track their usual diets, physical activity, and blood sugar levels, creating a baseline. In the second stage, a subset of participants will regularly visit a clinic. There, theyll be given a controlled, specific meal, and be monitored for a series of biomarkers such as how their blood sugar levels change.

Another subset of volunteers will be given three different types of diets, one following another with a washout perioda breakin between. The prepared study foods will be eaten at home, so the participants can go about their daily lives.

Finally, up to 1,000 volunteers will stay at a clinic for three two-week-long holidays. Here, their three meals will be strictly controlled, and outside food not allowed. While seemingly harsh, going from free range to controlled is the gold standard for nutrition science, because it weeds out other variables.

While on the diet, all three groups will undergo a series of clinical tests, ranging from genetics and microbiome composition to blood sugar levels, metabolism, and urine. Psychology and behavior measures will also be assessed. Further on the docket are socioeconomic factors, such as zip code.

With these comprehensive measures, we are removing a lot of that noise that we had for years, created by the factors that we were not measuring before, said Dr. Jos Ordovs, a nutrition scientist at Tufts University.

As the study gathers data, on the back end, software engineers will begin building an infrastructure for storing, organizing, and searching the datasets. This library of data is then passed on to AI scientists to create models and algorithms that predict a persons individual response to a diet. Finally, another five-year period will validate those models in clinical trials.

Its not the first time a study has linked precision nutrition with AI. In 2015, an Israeli study of 800 people monitored their blood sugar levels and microbiome to parse out how individuals respond to different types of sugar intake. Using machine learning, the study built a software program to predict diets best suited for someone who is diabetic or hoping to lose weight.

But Nutrition for Precision Health is larger and far more sweeping than anything previously attempted. For now, the program is still at the planning stage, with a full launch expected in early 2023.

To Rodgers, the study isnt just about generating a wealth of data to fuel discovery science for years to come. The resulting tools, methods, and paradigm shift will have the potential to truly transform the field of nutrition science, he said.

Keto Diets Cause Scarring Of Heart Tissue And Inhibit Mitochondria Production In Rats – IFLScience

Posted: February 17, 2021 at 10:54 am

Ketogenic diets, which forgo carbohydratesto replace them with fats, have becomeextremely popular in recent years,rising to the top as themost-searched-for diet of 2020.Whilst these diets are effective in treating epilepsy and have applications in various other diseases, the evidence for use as a tool for weight loss in healthy individuals remains disputed.

In a recent study performed on rats,researchers have suggestedthat keto diets are having a dramatic impact on peoples hearts.The results showedthe high-fat-diet-induced changes within the rats hearts, reducing the production of mitochondria and creatingscar tissue.Their work was published in the journal Signal Transduction and Targeted Therapy.

The basis of ketogenic diets revolves around bringing the body into a state of ketosis through consuming mostly fats.Ketosis is a normal metabolic response that kicks in when the body doesnt have enough glucoseto ensure enough energy is provided. The liver begins turning fat molecules into ketones, which are released into the bloodstream and used as an alternative energy source.

As this process consumes fat molecules and lowers blood glucose and insulin levels, the diet has become popular amongpeople looking for weight loss.The jury is still out on whether ketogenic diets are safe andeffective for long-term weight goals,with many swearing by the success they have had and others disputing it as an alternative to traditional weight-loss methods.

In the latest piece of research, a collaboration between Fudan University, Shanghai, andSichuan University, Chengdu, the researchers delveddeeperintothe cellular impacts of ketosis on the heart. The most abundant ketone body formed during ketosis is-OHB (70 percent of all ketones), which has been thought to have multiple secondary benefits for the immune system. However, researchhas suggested that elevated -OHB is linked with poorer cardiac health, alongside variousother concerning correlations between ketosis and mortality.

The study involvedthree groups of six rats that were fed either a ketogenic diet, normal diet, or calorie-restricteddiet over a period of four months.After the four months, the rats hearts wereanalyzedto look for cellular changes between each diet. In the ketogenic group, the rats demonstrated an increase in the ketone -OHB levels and a resulting activation of the geneSirt7, inhibiting the biogenesis of mitochondria. Furthermore, when this pathway was translated to human cultured cells, it led to apoptosis (celldeath) of cardiac cells and fibrosis (scarring).

These results do not provide clear evidence that ketogenic diets damage the human heart, nor that all ketogenic diets should be stopped. Cellular and animal models were used and there is no data onthe long-term effectsof ketosis on human organs, which would require more extensive testing and clinical trials. However, it does highlight an avenue of inquiry that should be followed to ensure ketogenic diets are safe for use as a weight-loss tool. The authors call for further trialsover a longer period, but in the meantime suggest ketogenic diets should be avoided for weight loss unless required by a health condition.

Improve your health with the Mediterranean diet – Idaho Press-Tribune

Posted: February 17, 2021 at 10:54 am

Eating a nutritious diet is important to improving your heart health. Pohley Richey, a registered dietitian and health coach with Saltzer Health, says that the Mediterranean diet is one way to minimize processed foods and sugar while increasing fiber in your daily meals.

The diet has evolved over the last 5,000 years in the Mediterranean region, she said.

It really came into popularity in the 1960s when people from the region were studied and shown to

have a lower incidence of heart disease, Richey said.

The Mediterranean diet is based on the traditional foods that people have eaten for generations in Italy,

Greece and other Mediterranean countries with an emphasis on:

Whole, unprocessed, natural foods

Less sugar

Local, seasonal fruits and vegetables

Whole grains

Heart healthy fats like nuts, olive oil, and other seeds

Protein from legumes, lentils, chickpeas, and seafood

Its not necessarily about a specific food per se but about this overall style of eating, Richey said.

Research has shown that the diet promotes wellness and decreases the risk of heart disease, cancer,

diabetes and other chronic conditions.

Richey describes the Mediterranean diet as super versatile.

It is super easy to implement. Its delicious. There is a lot of variety involved. It can be really simple,

easy, and a fun way to eat, she said.

With any diet, Richey recommends starting small. If you are looking at making a complete revamp it

gets a little bit overwhelming, she said. Think of very specific things that you can pull from this dietary

pattern and implement.

To get started, she recommends:

Try going one meal a week meatless

Eat more legumes

Experiment with new foods like chickpeas or lentils

Shop at local farmers markets

Eating Unhealthy Foods May Diminish Positive Effects of an Otherwise Healthy Diet – SciTechDaily

Posted: February 17, 2021 at 10:54 am

Study by researchers at Rush University Medical Center finds adding more foods that are part of Western diet may reduce cognitive benefits of Mediterranean diet.

A study by Rush researchers finds that adding more foods that are part of Western diet may reduce cognitive benefits of the Mediterranean diet.

Eating a healthy diet, such as the Mediterranean diet, has a positive impact on health, but little is known about the effects of including unhealthy foods in an otherwise healthy diet. Now researchers at Rush University Medical Center have reported diminished benefits of a Mediterranean diet among those who frequently eatunhealthy foods. Results of their study were published in Alzheimers & Dementia: The Journal of the Alzheimers Association.

Eating a diet that emphasizes vegetables, fruit, fish and whole grains may positively affects a persons health, said Puja Agarwal, PhD, a nutritional epidemiologist and assistant professor in the Department of Internal Medicine at Rush Medical College. But when it is combined with fried food, sweets, refined grains, red meat, and processed meat, we observed that the benefits of eating the Mediterranean part of the diet seem to be diminished.

A Mediterranean diet is associated with slower rates of cognitive decline in older adults.

The observational study included 5,001 older adults living in Chicago who were part of the Chicago Health and Aging Project, an evaluation of cognitive health in adults over the age of 65 conducted from 1993 to 2012. Every three years, the study participants completed a cognitive assessment questionnaire that tested basic information processing skills and memory, and they filled out a questionnaire about the frequency with which they consumed 144 food items.

The researchers analyzed how closely each of the study participants adhered to a Mediterranean diet, which includes daily consumption of fruit, vegetables, legumes, olive oil, fish, potatoes and unrefined cereals, plus moderate wine consumption. They also assessed how much each participant followed a Western diet, which included fried foods, refined grains, sweets, red and processed meats, full-fat dairy products and pizza. They assigned scores of zero to five for each food item to compile a total Mediterranean diet score for each participant along a range from zero to 55.

The researchers then examined the association between Mediterranean diet scores and changes in participants global cognitive function, episodic memory and perceptual speed. Participants with slower cognitive decline over the years of follow up were those who adhered closest to the Mediterranean diet, along with limiting foods that are part of Western diet, whereas participants who ate more of the Western diet had no beneficial effect of healthy food components in slowing cognitive decline.

There was no significant interaction between age, sex, race or education and the association with cognitive decline in either high or low levels of Western diet foods. The study also included models for smoking status, body mass index and other potential variables such as cardiovascular conditions and findings remained the same.

Western diets may adversely affect cognitive health, Agarwal said. Individuals who had a high Mediterranean diet score compared to those who had the lowest score were equivalent to being 5.8 years younger in age cognitively.

Agarwal said that the results complement other studies showing that a Mediterranean diet reduces the risk of heart disease, certain cancers and diabetes and also support previous studies on Mediterranean diet and cognition. The study also notes that most of the dietary patterns that have shown improvement in cognitive function among older adults, including the Mediterranean, MIND, and DASH diets, have a unique scoring matrix based on the amount of servings consumed for each diet component.

The more we can incorporate green leafy vegetables, other vegetables, berries, olive oil, and fish into our diets, the better it is for our aging brains and bodies. Other studies show that red and processed meat, fried food and low whole grains intake are associated with higher inflammation and faster cognitive decline in older ages, Agarwal said. To benefit from diets such as the Mediterranean diet, or MIND diet, we would have to limit our consumption of processed foods and other unhealthy foods such as fried foods and sweets.

The study and its findings cannot be readily generalized. Future longitudinal studies on diet and cognition among the middle-aged population are needed to extend these findings.

Reference: Unhealthy foods may attenuate the beneficial relation of a Mediterranean diet to cognitive decline by Puja Agarwal, Klodian Dhana, Lisa L. Barnes, Thomas M Holland, Yanyu Zhang, Denis A. Evans and Martha Clare Morris, 7 January 2021, Alzheimers & Dementia: The Journal of the Alzheimers Association.DOI: 10.1002/alz.12277

Other researchers at Rush involved in the study at Rush were Klodian Dhana, PhD; Lisa Barnes, PhD; Thomas Holland, MD; Yanyu Zhang, MS; Denis Evans, MD; Martha Morris, ScD.

The study was supported by a grant from the National Institute on Aging.

Sneak More Fruits and Veggies Into Your Diet With a Top-Rated Cold Press Juicer – msnNOW

Posted: February 17, 2021 at 10:54 am

Shopping for a new juicer is no easy task, which is why in the Good Housekeeping Kitchen Appliances Lab, we test juicers to find the best ones that are actually worth your money. We do so by juicing just about everything pulpy apples that have a large diameter and oxidize quickly, floppy kale which can often jam machines, and hard, fibrous carrots. We then measure multiple data points around key features to find the top juicers, including:

Output: How much juice does the machine create? How much pulp does it yield, and how dry is the pulp? (Hint: It should be dry, as this indicates more juice has been squeezed out.)

Taste: How sweet is the juice and how smooth is it? The sweeter and less pulp the better.

Temperature: What is the temperature of the resulting liquid? And how does it compare to others that are being tested at the same exact time?

Out of the dozen cold press juicers we tested, these are the best cold press juicers to buy in 2021, according to both Good Housekeeping Institute Lab tests and best-sellers with lots of glowing reviews online:

If you've been hearing a lot of buzz about cold press juicers lately, you may be wondering what exactly they are and how they differ from all the other types of juicers on the market. The key distinction is in how they work:

If you're looking to get more nutrients into your diet, most experts say a cold press juicer is the way to go because the slow juicing process is more gentle on ingredients and retains more nutrients though Stefani Sassos, MS, RDN, Registered Dietitian for the Good Housekeeping Institute, points out that recent research suggests juice storage may matter more than how exactly you make it.

It seems that storage conditions are more important when it comes to the nutrient capacity of juice, she says,so drink it immediately or store it in the coldest part of the fridge but dont let it sit out at room temperature. It's also worth noting that generally cold press juicers require a bit more prep work (read: you'll need to cut smaller chunks of fruits and vegetables) than centrifugal juicers due to their small feed tubes.
