Posted: August 29, 2017 at 3:42 pm

GET rid of belly fat fast with these two exercises.

GETTY

With summer coming to an end, this could make a lot of people indulge in foods they didnt dare to over the warmer, bikini-weather months.

But if you are looking to lose some stubborn belly fat, it turns out there are only two exercises you need to do to make it melt away.

The two exercises are: Kettlebell swings and squat thrusts.

If you are looking to lose that belly fat, try these simple easy to follow tips that will help you on the road

1 / 10

Eat every three hours - Passing on breakfast will send your body into starvation mode, meaning your body starts to store everything youve eaten as fat, and youre midsection is the first to suffer the consequences

The way it works is you do 15 repetitions of the kettle bell (or dumbell) swing followed immediately by 15 reps of the squat thrust.

Without resting, you then do 14 reps of each and continue to count down and do this without rest until you hit zero.

This will result in 120 reps of each exercise and at three seconds per rep they are done at a fast pace and will be over in around 12 minutes.

7 Simple Swaps to Make for Lasting Weight Loss – NBCNews.com

Posted: August 28, 2017 at 7:41 am

Let our news meet your inbox.

Its a fair statement to say that at any one time, a large percentage of us are trying to lose weight. As a registered dietitian, I see this in my own practice at least 50 percent or more of the individuals who come in to see me are doing so with the hopes of dropping at least 20 pounds.

Its not easy, and many fall short of their goals. Their failures are not due to a lack of motivation or willpower; its often because they tried to make too many big changes all at once. Even their goals were too big. In fact, one study found making smaller and easier changes to eating habits on a regular basis was more likely to yield success in weight loss.

Almost everyone can make one small change every day. One major way you can push forward with weight loss is to cut calories. Here are my top swaps that have helped take my patients to the next level in their weight-loss goals:

Instead of having a high-calorie, high-sugar caramel latte, consider a coffee with unsweetened almond milk and cinnamon instead. You can whip up the almond milk and add tons of yummy flavors with the cinnamon, all while saving you over 1,600 calories a week, which could amount to over 20 pounds lost in one year!

This is an obvious one, but probably one of the most challenging to implement. We still are drowning in soda, and its costing us our health. But giving up a 12-ounce can of cola (140 calories) for water, or a naturally flavored seltzer water, can help you lose up to 14 pounds a year. Just make sure you resist the urge to cut calories by incorporating a diet version of your favorite cola. Artificial sweeteners may have consequences to your weight as well, according to several recent studies.

Eating zucchini noodles instead of pasta, just once a week, can help you lose over 2 pounds in a year and making it all the time can lead to even further weight loss. This habit can be especially helpful for individuals with diabetes or non-alcoholic fatty liver disease by decreasing the reliance on insulin.

Alcohol can be a real challenge when youre trying to lose weight, but it can be the kiss of death if your alcohol of choice tends to be one thats potentially loaded with sugar. Daiquiris, pia coladas and margaritas all fall into this category. Consider swapping your margarita for a 5-ounce glass or red or white wine just three nights a week and you can save you up to 1,000 calories a week, or 15 pounds in one year.

Swap high-calorie dressings for an amazing oil and balsamic vinegar combination to shave off about 3 pounds per year (thats a lot to the serial dieter always looking to lose the last 5 pounds).

Think an oil and balsamic combo is boring? Think again. My view of salads and what goes on them completely changed when I found a specialty oil and vinegar store near my house. Now I whip up delicious masterpieces like blueberry balsamic paired with lemon olive oil, and quince balsamic paired with lime olive oil. Ive fallen back in love with salads that were getting boring, and I fit better in my jeans because of it.

If I told you to swap your mid-afternoon bag of potato chips for some celery and hummus, youd probably think I was crazy. So instead of having potato chips every afternoon, swap them for crunchy Parmesan crisps that you either make you or buy. While calories may differ by brands, some popular options I looked at showed a serving of potato chips running about 140 calories, while a serving of Parmesan chips having only 100 calories and almost no carbs! Thats a potential savings of over 250 calories a week.

Cauliflower rice is found nationwide in either fresh or frozen versions and is easy to prepare. Plus, cauliflower is one of the best vegetables to consume if youre interested in reducing your risk of cancer. If that doesnt motivate you, then how about this: Cauliflower rice has 40 calories in one cup, while white rice has 170. Thats a saving of 130 calories! If you make that change just three times a week, you can save about 20,000 calories in a year.

Remember, weight loss is based on many variables calories are only part of the equation. Genetics, activity level, gender, age and disease status all are factored into your ability to lose, or maintain weight. Despite this, small lifestyle changes, like swapping some of the foods suggested here, may help to move you in the right direction.

This Woman Had Major Weight Loss Surgery, And This Is What She Wants You To Know – Delish.com

Posted: August 28, 2017 at 7:41 am

When 28-year-old Julia Nathan decided to undergo bariatric surgery after years of struggling with her weight, she wasn't prepared for people's negative reactions to her method of weight loss, or the pain that a necessary follow-up surgery would cause.

Nathan recently shared her story with Health magazine, and these are her biggest takeaways if you're considering a major weight-loss surgery.

Many people don't understand the decision. When she told people how she lost weight, they often seemed disappointed, like she "cheated" by getting surgery, she says. This was understandably frustrating, but ultimately, she knew the struggle it took to get there. After surgery, she still had to exercise often and keep her portion control in check to lose weight. Plus, because she went the gastric sleeve route, overeating comes with the risk of vomiting, diarrhea, or ripping her stomach lining.

Advertisement - Continue Reading Below

A few factors made her a good candidate. She was young, didn't have any health complications like diabetes, and had tried to lose weight with diet and exercise first.

The surgery itself wasn't so painful. She recalls waking up from the two-hour surgery and being surprised at how good she felt. She spent one night at the hospital and then went to her dad's house to recover. Her gut was sore, but not in pain.

Post-surgery, she was on a liquid diet for two weeks. She was eating about 600 to 800 calories a day, and surprisingly wasn't nearly as hungry as she used to be. She did have an allergic reaction to the whey protein shakes she was drinking though.

The second surgery was brutal. A year after her gastric sleeve procedure, Nathan had lost 100 pounds and decided to get another surgery to remove seven pounds of excess skin. The pain from that surgery was "constant and more severe," and the medication she took after made her throw up, which of course hurt her stomach even more.

She's got scars, but she embraces them. They are long and visible, she says, especially the one that runs from one hip to the other. Instead of being embarrassed by them, though, Nathan sees them as badges of honor. "They remind me of what I went through and how proud I am to have taken action to improve my life."

How Is New Technology Changing the Weight Loss Industry? – TG Daily (blog)

Posted: August 28, 2017 at 7:41 am

The weight loss industry is never hurting for customers. In the United States, over two-thirds of adults are considered overweight or obeseyet we idolize lean, fit bodies in our culture. The result is an overwhelming number of people willing to spend money on anything that promises them a fast, effective weight loss solution. Ultimately, that adds up to be a $20 billion industry.

Though its been around for decades and has experienced significant changes in that time, the weight loss industry is undergoing its most extreme evolution nowthanks to new technology. But how exactly is tech changing the weight loss industry? And is it a good or bad thing for consumers?

These are some of the most significant changes weve seen:

Like with most industries, businesses and marketers in the weight loss sector are starting to step away from personal interactions and tangible products, and toward self-sustaining digital systems that can be distributed and downloaded freely. There are pros and cons to this, but for consumers this is going to mean an even bigger explosion of tech-based weight loss solutionsand possibly available at a cheaper rate.

Future developments could include more sophisticated AI interfaces, capable of analyzing your eating and exercise habits automatically, and making recommendations according to those individual needs, or integration with medical apps and devices, especially in more extreme cases of obesity. For now, if youre interested in losing weight, you have more options and gadgets to help you than ever beforeso take advantage of them.

Weight loss diet: Eating THIS before exercise could affect how your body burns fat – Express.co.uk

Posted: August 28, 2017 at 7:41 am

A study suggests exercising on an empty stomach can in fact promote more favourable changes in body fat.

Research carried out by the University of Bath studied 10 overweight men by asking them to walk for 60 minutes at 60 per cent oxygen consumption, first on an empty stomach and then after eating a carbohydrate-rich breakfast.

Blood and fat tissue samples were then taken before and after exercise for analysis.

The researchers found two genes (PDK4 and HSL) increased when they walked on an empty stomach but decreased when they had eaten the carbohydrate-rich breakfast.

The rise in the genes suggests that exercising on an empty stomach burns fat as energy.

Previous research has supported this idea, but other studies on weight loss suggests eating breakfast is essential in shedding the pounds.

Milton Stokes, R.S., author of Flat Belly Diet! For Men, told Mens Fitness: Its like putting logs on a wood-burning stove. You need that initial input to get your metabolism going for the day.

The aim should be to intake around 400-600 calories within an hour of waking up.

Stokes advised focusing on protein, healthy fats and fibre, as these will leave dieters feeling fuller for longer.

There are a few meals to try in the morning that cover all of these ideals.

Jorge Cruise, author of The Belly Fat Cure, advised eggs with avocado/

He said: Avocados are nature's ideal fruit for weight loss. They replace sugar with appetite-curbing good fat."

If you prefer a quick shake, then choose one with whey protein.

David Grotto, R.D., author of 101 Foods That Could Save Your Life said: Whey is rich in branched chain amino acids, which stimulate muscle growth.

The more muscle you have, the greater the fat-burning capacity of your metabolism.

Finally, a simple yoghurt topped with fresh fruit to make it interesting and sprinkled with high-fibre cereal is another option.

Ketogenic diet loved for fast results, but does it work? – Gears Of Biz

Posted: August 27, 2017 at 12:43 pm

Lose weight by eating more fat it almost sounds too good to be true. But followers of the ketogenic food plan claim it not only works, it can revolutionise the way you eat.

Although the keto diet as its known has been hailed as being extremely effective for weight loss, its not without its share of controversy.

Those who subscribe to a keto-based food programme eat a diet thats significantly higher in fat this is offset by a major reduction in carbohydrates which is understood to put the body into a metabolic state called ketosis.

In essence, nutritional medical expert Fiona Tuck explained to Today TonightAdelaide, the body burns fat to use as fuel.

Right now the diet being touted as the hot new way to strip unwanted kilos with celebrities including Guy Sebastian crediting their success to following the high-fat food regime.

But is the diet a safe way to sustainable weight loss? Fiona Tuck breaks it down.

An extreme keto diet is made up of 75 per cent healthy fat, 20 per cent protein and just five per cent carbs, which means limited fruit and vegetables, she said.

While she said the food plan would work for quick weight loss, its not one she thinks is beneficial long term.

We have to be very careful not to take the body into an extreme case of acidosis (caused by an overproduction of acid in the blood) because that can actually be life threatening or fatal.

However Ms Tuck does believe the diet can be followed safely, if carb levels are increased to 50 or 100 grams.

She also advocates for following a dietary plan that includes a wide range of fresh foods.

You could not be getting enough of those brightly coloured fruits and vegetables which could put us at risk of nutritional deficiency, she warned.

For some the health benefits of following the keto diet have meant a surprising turn-around in how theyve been able to manage chronic health conditions.

As reported previously byDaily Mail Australia, Queensland woman Kim Fletcher claimed she lost 50 kilos by following the high fat food plan, and was able to put her auto immune condition into remission.

She explained that at the height of her illness, her weight had tipped 120 kilograms but a chance sighting of an article in a local paper on the benefits of the diet sparked her interest.

Fifteen months later, shes shed 50 kilos following a high fat, low carb food plan and said shes never felt better.

Ive gone from a size 22 to a size 10; Ive been able to even start shopping for new clothes, she said.

Its a long way from being bedridden and unable to leave the house.

Watch it! Artificial sweeteners can make you fat – Vanguard

Posted: August 27, 2017 at 12:43 pm

By Bunmi Sofola

THE lives of everyone watching their weight were recently thrown into disarray when a leading food expert claimed that far from making us thinner, diet products containing artificial sweeteners may actually be responsible for weight gain.

For many of us, low-fat versions of our favourite foods yoghurt, fizzy drinks, spreads,biscuits, crisps and cheesemake us feel we can safely indulge in a little of what we want without piling on the pounds, by swapping natural sugars (at 40 calories a gram) for sugar substitutes that have just two calories.

But although chemical sweeteners were once thought to be the holy grail for dieters and diabetics, opinion has started to turn against them. So have we been misled for years about the ability of sweeteners to help us reduce our waistlines? Yes,says Professor Susan Swithers, who analysed scientific data from the past five years to produce her findings. Consuming artificial sweeteners not only adds to weight gain but, over time, is generally responsible for an increase in bad health out comes, says the professor, who is based at Purdue University, Indiana, in the US.

Our research followed people of different ages and weights (many werent overweight at the start), and those who drank a lot of diet sodas and other artificially sweetened foods were found to suffer Type 2 diabetes, heart disease and stroke more often, and they tended to be more overweight. But Gavin Partington, of the British Soft Drinks Association, argues that Professor Swithers findings run contrary to decades of scientific research. So, whos right? Heres what experts say you need to know.

What are artificial sweeteners?

Unlike naturally occurring sweeteners such as sucrose (sugar) and fructose (fruit sugar), artificial sweeteners are synthetically manufactured to be non-nutritiveso they contain few or no calories. Five artificial sweeteners are permitted for use in the UK; aspartame, saccharin, acesulfame potassium (known as acesulfame K), cyclamate and sucralose.

Will you pile on the pounds?

Several studies show consuming low-calories artificial sweeteners makes people more likely to pile on weight than reduce it, according to Joanna BIythman,Britains leading investigative food journalist and author of: What To Eat. Our

bodies are designed to process natural foods, so expect calories along with a sweet taste, she says. So rather than helping us consume less sugar overall, by interfering with our satisfaction signals, artificial sweeteners cause us to crave even more

sweet food. A US study showed that while people who drank one to two cans of full-sugar fizzy drinks a day increased their risk of becoming overweight or obese by nearly 33 per cent over seven to eight years, those who replaced them with

diet alternatives had a 65-per cent risk. When you eat normal sugar, your taste buds tell the brain sugar is on its way,

says personal trainer James Duigan, of Bodyism, the celebrity London gym. So when the body receives a low-calorie artificial sweetener instead of sugar and the calories dont reach the stomach, the body is confused! Some sweeteners are

even thought to change hormonal activity, which can cause you to hold on to fat and lead to weight gain. Telling people to drink diet sodas could backfire as a public health message, Professor Swithers says. (The message to limit sugar

intake needs to be expanded to limit intake of all sweeteners, not just natural sugars.)

Do they give you a sweeter tooth?

Saccharin can be between 200 and 700 times sweeter than sugar, says James Duigan. Consuming a lot makes fruit and other naturally sugary foods cease to seem sweet, causing you to develop an even sweeter tooth. A sweet taste also

increases your appetite. A US. study two years ago found non-calorific sweeteners encouraged animals to eat more calorie-rich, sweet-tasting food, making them gain weight.

Are they bad for you in other ways?

A popular nutritional therapist, Dr. Marilyn Glenville is the author of Fat Around The Middle, and a specialist in womens health. She has serious concerns about ourconsumption of artificial sweeteners, and particularly about aspartame, one

of the most widely used chemical sweeteners, which is deemed safe by the European Food Standards Agency. It is 180 times sweeter than sugar and can

lead to pinge eating and cravings. Its also been linked to mood swings and depression because it alters levels of the brain chemical serotonin, says Dr. Glenville. There are also concerns that aspartame might be addictivepeople

who drink three to four cans of diet soft drinks every day, or regularly chew sugar-free gum, may experience withdrawal symptoms if they try to stop.

She always advises patients to avoid food or drinks containing artificial sweeteners and to check the small print on ingredients even with non-diet foods. Independent

studies on lab animals have suggested artificial sweeteners can pose serious health problems, including neurological issues, memory impairment and decreased liver function. Aspartame is one of the most researched ingredients I can think of,

says nutritionist Ian Marber. (And while some schools of thought believe it is carcinogenic, there is no proof of that. However, it taxes the liver and increases blood fat levels, which can lead to heart disease, diabetes and stroke risk, as well as weight gain.) Some research has even linked the consumption of artificially sweetened food and drinks to migraines and premature birth.

Are natural sugars better for you?

Nutritionist Ian Marber says there is a widely held belief that naturally occurring sugars, like

honey or agave syrup, are healthier than white sugar. But that isnt necessarily the case, he says. Natural sugars are not harmless. I see people who wouldnt touch a can of Coke, cover their breakfast in organic agave syrup. Too much of any sweetener can make you gain weight).

Any healthier alternatives?

James Duigan believes xylitol and the plant-based sweetener stevia are the best options. His tip for anyone trying to cut back on the sweet stuff altogether?

Cinnamon. Its a wonder ingredient, he says. (It tastes great, reduces cravings for sweet stuff, and helps regulate your blood sugar levels. I stir it into my coffee

and eat it on yoghurtyou can add it to your breakfast porridge.)

Full-sugar or diet drinks?

JAMES DUIGANS advice is to steer clear of fizzy drinks completely. If you want a healthy drink to quench your thirst, you cant do better than a long, cool glass of water, he says.

Weight loss: This is the best trick YOU can do to lose weight without even trying – Express.co.uk

Posted: August 27, 2017 at 12:42 pm

And the best trick you can do to lose weight without a diet plan involves the weighing scales.

Weight loss can be made much more likely if you weigh yourself everyday, a new study has found.

Previous experts have recommend weighing yourself less for weight loss success, but it now seems the reverse may be true.

Scientists at Drexel University and the University of Pennsylvania discovered when women weighed themselves daily over the course of two years, they lost weight.

The study looked at 294 women at university, who were of different weights and body shapes, and measured their body fat percentage.

The scientists found the women who weighed themselves everyday avoided weight gain and even experienced weight loss.

Dr Diane Rosenbaum, a psychologist at the University of Pennsylvania, said: The losses in BMI and body fat percentage were modest, but still significant, especially keeping in mind that these women were not part of a weight loss program.

We did not expect that, in the absence of a weight loss intervention, folks would be losing weight.

The study was published in the Journal of Behavioral Medicine.

Meghan Butryn, PhD, an associate professor in the College of Arts and Sciences at Drexel said: Regularly weighing yourself can motivate you to engage in healthy eating and exercise behaviors, because it provides you with evidence that these behaviors are effective in helping you lose weight or prevent weight gain.

Similarly, if you see weight gain on the scale, that information can motivate you to make a change.

An expert in body transformation has revealed some exercises you can do in the comfort of your own home to help reduce stomach fat.

Chris Wharton, a specialist in body transformation, said: He said: By carving out just 10 to 20 minutes a day to create a morning routine, you can make a profound improvement to your physique.

Now only will you look great, you will have a lot more energy, enjoy much better sleep quality and feel far happier in general.

Carol Kirkwood, a weather girl for the BBC, has revealed her plan for keeping slim.

How Conor McGregor’s Weight Loss Ahead of His Big Fight May Harm His Body – Scientific American

Posted: August 27, 2017 at 12:42 pm

Before he faces off against undefeated boxer Floyd Mayweather, UFC champion Conor McGregor must conquer the scale.

And that could prove an even more dangerous opponent.

In pre-fight trash talk, Mayweather has claimed that McGregor looks extremely heavy and has been scrambling to try to drop 10 pounds. (Both fighters have to come in under 154 pounds at the weigh-in on Friday afternoon if their much-hyped bout is to proceed.)

The truth is, though, shedding 10 pounds in a couple days is no big deal for most MMA fighters.In the past, McGregor has reportedly cut more than 25 pounds in eight days time.

The key question is whether they can do it without damaging their health. And even the nutritionist charged with guiding McGregor to his fighting weight said thats a difficult balance.

Its nothing Id recommend to everyday people, George Lockhart, the nutritionist, told STAT in an interview. I always tell people if health was your number one priority, MMA is not the sport you should be going into.

MMA fighters are known to dehydrate themselves using everything from saunas to sweat suits, hot baths to water pills to shed up to dozens of pounds in the days ahead of a weigh-in. After making weight, they try to quickly regain it by eating food and drinking water in hopes of gaining the competitive advantage of size over their opponent.

Lockhart, a former fighter and Marineveteran, generally starts on the Tuesday before a weigh-in. He removes sodium from a fighters diet and offers herbal diuretics that include potassium to replenish lost nutrients. Hell also have a fighter taper water consumption over several days two gallons on Tuesday, one gallon on Wednesday, occasional sips when thirsty on Thursday. The day before the weigh in, Lockhart takes carbohydrates out of fighters diet and cleans out his or her intestinal tract. On that final night, fighters sometimes work out or take a hot bath.He monitors vitals, including body temperature and blood pressure, throughout the process.

Ten pounds in four days is like a hiccup, Lockhart said. What Floyds talking about, it just shows hes probably never cut weight before.

But dropping weight that fast even just 10 pounds draws concerns from doctors. Dr. Larry Lovelace, a ringside physician in California, told STAT several fighters have died over the past few years from the practice, which athletic officials have called the biggest problem in the sport today.

A 2013 study in the Journal of Strength and Conditioning Research found that 39 percent of MMA fighters studied experienced significant or serious dehydration before their fights. Lovelace said the body doesnt fully rehydrate for at least two days well after a fight ends. That means fighters could experience muscle cramps and loss in agility while in the ring, he said.

It only takes 2 percent dehydration to impair your performance, Lovelace said. Theres no way theyre going to recover, and its definitely going to affect their performance.

There are bigger health risks, too. They include:

The brain: When a fighter takes a punch to the head, the brain rattles off the front and the back of the skull. Thats not healthy in the best of conditions. Dehydration makes it worse. The brain is bathed in fluid, said Dr. Edmund Ayoub, vice president of the Association of Ringside Physicians. Without that fluid, the brain has less cushion. Therefore, the risk of injury could be greater for a fighter who spars during the process of weight cutting. The brain can hit harder against the skull, Ayoub said. You may have more [risk for] brain injury.

The heart: A fighters heart beats faster than normal when dehydrated. If you normally walk around with a resting heart rate of 72, now it may be 90 or 100, Lovelace said. So going into a cage to fight, there are potential cardiac risks.

In a 2013 interview with Vice Sports, ringside physician Dr. Michael Kelly said dehydration can impact how the body regulates sodium and potassium levels and, in turn, mess with the cardiac fibers conducting electricity inside the heart. So if those signals arent propagating along the channel correctly, Kelly said, the heart can go into an irregular heartbeat or fatal heart rhythm and wind up in cardiac arrest.

The kidneys:Nephrons, the tiny structures inside the kidney that produce urine to remove waste from the body, malfunction without enough water.Your kidneys literally dry up, Ayoub said. When kidneys get dried up, you can get kidney damage. In 2015, fighter Johny Hendricks had to be rushed to the emergency room after weight cutting led to intestinal blockage and a kidney stone. Doctors say theyre also at risk of sustaining chronic kidney issues due to the practice.

Ayoub thinks fighters would remain healthy if they made sure to lose no more than 2 percent of their body weight each week. If McGregor had to lose 10 pounds, for instance, he should aim to shed it over three weeks instead of just one, Ayoub said.

Lovelace, though, said there is nothing to be gained from the practice of weight cutting,in part because both fighters are often doing the same thing, canceling out any potential advantage from packing on pounds immediately after the weigh-in.

Lockhart, for his part, believes fighters will keep cutting weight no matter what. So he considers it his job to help them do it as safely as possible. Theres no degree for weight cutting, Lockhart said. You need people to show them how to do it in the proper way.

MMA writer Iain Kidd, who has observed Lockharts training methods for a forthcoming book, puts it this way: There are ways to do it safer but not ways to do it safely.

Human Gut Germs Dictated by Diet – WebMD

Posted: August 27, 2017 at 12:40 pm

By Mary Elizabeth Dallas

HealthDay Reporter

THURSDAY, Aug. 25, 2017 (HealthDay News) -- What you eat, or don't eat, affects the mix of germs in your digestive tract, new research indicates.

Thousands of microbial species thrive in the human intestine, helping people digest fiber and make vitamins and other molecules. They also help strengthen the immune system and protect against potentially harmful bacteria, Stanford University School of Medicine researchers say.

The rise in farming some 15,000 years ago dramatically changed the human diet, the researchers noted. And in just the last 100 years, people have become increasingly sedentary and less likely to consume fiber-rich whole grains, fruits and vegetables.

Antibiotics, cesarean sections and other lifestyle changes have also helped shift the composition of microbes in the human gut, the study authors added.

To see how "progress" may have affected microbial diversity, the researchers examined seasonal changes in the gut microbes of the Hadza in Tanzania -- one of the world's last remaining traditional hunter-gatherer populations.

The Hadza rely primarily on meat, berries, baobab (a fruit), tubers and honey. The researchers found their gut bacteria different and more diverse than the gut bacteria of those living in the cities of industrialized countries.

"The 100 to 200 Hadza sticking to this routine will possibly lose it in a decade or two, maybe sooner. Some are using cell phones now," senior study author Justin Sonnenburg said in a Stanford news release.

"We wanted to take advantage of this rapidly closing window to explore our vanishing microbiota," said Sonnenburg, an associate professor of microbiology and immunology.

Stool samples from the Hadza showed their mix of gut microbes changes with the seasons and their diet.

The significant modifications made to the human diet over the past 10,000 years could help explain the loss of diversity in the germs residing in the typical modern digestive tract, the study suggests.

"Surviving hunter-gatherer populations are the closest available proxy to a time machine we in the modern industrialized world can climb into to learn about the ways of our remote human ancestors," Sonnenburg said.

"Our own microbiota can change significantly from day to day, or even within hours, in response to what we've been eating," said Sonnenburg. "Fiber's all that's left at the very end of our digestive tract where these microbes live, so they've evolved to be very good at digesting it. The Hadza get 100 or more grams of fiber a day in their food, on average. We average 15 grams per day."

The findings were published Aug. 25 in the journal Science.
