Study Highlights:

SAN DIEGO, March 15, 2012 (GLOBE NEWSWIRE) -- Overweight and obese adults who used an electronic diary program on a personal digital assistant did better at staying on diet and physical activity programs, researchers reported at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2012 Scientific Sessions.

People using the device, which provided tailored dietary and exercise feedback messages, were more successful in adhering to five treatment factors for weight loss:

The SMART (Self-Monitoring and Recording with Technology) study included 210 overweight or obese adults, 84 percent women, 79 percent white, who used a paper diary, a handheld electronic device without feedback, or a handheld device that provided daily messages.

Those using the electronic devices did significantly better than those using a paper diary for attendance, self-monitoring and energy and exercise goals.

At six months, the group that received the daily feedback messages from their device had more than a 5 percent weight loss, but over time adherence declined and weight gain occurred.

At 24 months, weight loss was similar across the three groups, but was slightly better in the group receiving feedback.

"The results suggest that using an electronic diary improves treatment adherence," said Lora E. Burke, Ph.D., study author and professor of nursing and epidemiology at the University of Pittsburgh in Pennsylvania. "Over time, participants' adherence declined, particularly in the later phase as contact frequency declined and subsequently ended. Adherence in the paper diary group declined more than in the device groups."

Study participants recorded their exercise levels and daily food and beverage intakes. Devices displayed the consumed daily calories and fat grams next to targeted amounts. Users with devices providing feedback received messages on diet once a day and exercise every other day.

Thirty-nine group sessions were offered in the first 18 months, followed by one "maintenance" session in the last six months.

THURSDAY, March 15 (HealthDay News) -- Researchers say they've discovered clues about how a fatty diet increases the risk of colon cancer.

"There have always been questions about why things like diet and obesity are independent risk factors for colon cancer. This study suggests how and why high-fat diets are linked to colon cancer," lead author Carmen Sapienza, a professor of pathology in Temple University's Fels Institute for Cancer Research and Molecular Biology, said in a university news release.

He and his colleagues examined healthy colon tissue from colon cancer patients and found that epigenetic marks on genes involved in breaking down carbohydrates, fats and amino acids -- which are all common in a fatty Western diet -- seem to have been retrained.

Epigenetic marks are chemical modifications that act as on/off switches for many genes, according to the release.

"These foods are changing the methylation patterns on a person's insulin genes so that they express differently, pumping out more insulin than the body requires," Sapienza explained. "In people that have colon cancer, their glucose metabolic pathways and insulin-signaling pathways are running at completely different levels than people who don't have colon cancer."

Cancer cells "love" insulin and studies have shown that tumors feed off insulin, Sapienza noted.

Most cases of colon cancer occur in people 50 and older, and it is unclear when these genetic changes begin. If such changes can be detected in other healthy tissues in the body, it might be possible to use blood or saliva tests to determine a person's colon cancer risk or diagnose the disease, Sapienza suggested.

The study was published in the March issue of the journal Cancer Prevention Research.

THURSDAY, March 15 (HealthDay News) -- Consuming the toxic metal cadmium in the foods you eat may raise your risk for breast cancer, a new Swedish study suggests.

Cadmium, which is found in many farm fertilizers, can make its way into soil and water, the researchers explained. Some of the main sources of cadmium in the diet are bread and other cereals, potatoes, root crops and vegetables. Once it enters the body, cadmium may mimic the effects of the female hormone estrogen, which can fuel the growth of certain breast cancers.

"Modern life has become increasingly dangerous for our breast health," said Dr. Marisa Weiss, director of breast radiation oncology and breast health outreach at Lankenau Medical Center in Wynnewood, Pa. "Now, there's cadmium hanging onto our carrots and whole grains, the very vegetables that are supposed to be good for us," she noted.

"To help our patients reduce their exposure to environmental chemicals (like cadmium), which might increase their risk for breast cancer, we have to partner with our farmers to make sure our foods are grown in healthy soil without chemically loaded fertilizers," said Weiss, who is also president and founder of Breastcancer.org. "Sticking to real, whole (unprocessed) foods remains a healthy strategy until we can be more sure of what's inside the package."

In the Swedish study, the researchers followed close to 56,000 women for more than 12 years. Women filled out food frequency questionnaires, which the researchers used to estimate how much cadmium they consumed in their diets. There were 2,112 breast cancer diagnoses during the follow-up period, including 1,626 estrogen receptor-positive and 290 estrogen receptor-negative cancers.

Women who had the highest amount of cadmium in their diets were 21 percent more likely to develop breast cancer than women who had the least amount of cadmium in their diets. This risk increased to 27 percent among women who were lean or normal-weight, the study showed. The risk was similar, 23 percent, for both estrogen receptor-positive and -negative tumors.

Those women who consumed higher amounts of whole grain and vegetables had a lower risk of breast cancer compared to women exposed to dietary cadmium through other foods.

"It's possible that this healthy diet to some extent can counteract the negative effect of cadmium, but our findings need to be confirmed with further studies," study author Agneta Akesson, an associate professor at Karolinska Institute in Sweden, said in a news release from the American Association for Cancer Research. "It is, however, important that the exposure to cadmium from all food is low."

The findings are published in the March 15 issue of Cancer Research.

Johanna Lampe, a member of the public health sciences division at Fred Hutchinson Cancer Research Center in Seattle, said the new study adds to a growing body of research linking cadmium exposure to breast cancer risk. "It adds another grain of sand to the pile," she said. "We would benefit from more research in this area to understand these risks better."

As many employees spend longer hours on the job, theyre also having more meals, snacks and celebrations with colleagues and that isnt always great for the waistline.

Some coworkers pressure dieters to eat forbidden foods. Others pass home-baked snacks desk-to-desk. Some tease colleagues about their diets, or even order them restaurant foods they arent supposed to eat. All these pose a major hurdle for people who are trying to slim down, according to a survey of 325 dieters last January by Medi-Weightloss Clinics. An ongoing poll of thousands of dieters on the weight-loss website SparkPeople cites co-workers as the second biggest source of negative pressure for dieters second only to spouses or partners.

And peers attitudes can make a difference. A study published in the journal Obesity last month says having teammates who exert positive influence is linked to greater weight loss among dieters. Being surrounded with peers who criticize or discourage a dieter has the opposite effect.

Colleagues often mean well. Some see offering delicious food as a sign of friendship or affection, says Becky Hand, a registered dietician with SparkPeople. Many people dont understand how hard it is for others to lose weight. They might feel guilty that they arent eating a healthier diet themselves. Some might be afraid of losing a friend who changes her life by losing a lot of weight.

Whatever their motivations, critical co-workers can make life tough for dieters.

DENVER, March 14, 2012 /PRNewswire/ --A just-released study from Johns Hopkins University has found that dieters that followed a low-carb diet like the Atkins Diet, shed more weight than those on a low-fat diet 10 lbs. more in six months and that the low-carb group lost more abdominal fat overall. A key finding was the lack of an adverse effect on vascular health in the low-carb group.

"The findings from the Johns Hopkins study demonstrate what we already know to be true Atkins has many scientifically-validated health benefits, including improvements in cardiovascular health markers," said Colette Heimowitz, vice president of nutrition and education for Atkins Nutritionals, Inc. "Atkins is the original and leading low carb weight loss plan that provides quick, satisfying weight loss based on an extensive body of research. It is a safe and effective diet plan for those looking to lose weight and keep it off long-term."

The study was presented on March 13 at an American Heart Association scientific meeting in San Diego by lead researcher Kerry Stewart, Ed.D., professor of medicine and director of clinical and research exercise physiology at the Johns Hopkins University School of Medicine and Heart and Vascular Institute.

The study examined overweight or obese but otherwise healthy individuals between the ages of 30 and 65 years over a six-month period. One group was randomly assigned a low-carbohydrate diet and the other a low-fat diet. The low-carb group consumed a diet made up of no more than 30 percent of calories from carbs and as much as 40 percent of their diet was made up of fats. Exercise was included for all participants and vascular health was checked before and after six months. Successful weight loss and reductions in total and abdominal fat, and BP were achieved with both groups. Greater reductions in weight, BMI, waist circumference, and body fat occurred in the low-carb group. The low-fat diet consisted of no more than 30 percent from fat and 55 percent from carbs.

Additionally, when individual variations were examined, a greater loss of abdominal fat was associated with enhanced vascular health.

In his presentation Stewart said, "These findings are contrary to common beliefs that the less fat you eat the better your cardiovascular health. What this study shows is that a low-carb diet not only helps people shed more weight and abdominal fat, but it did not have any harmful effects on vascular health. Overall, there was an improvement in vascular health that was related to how much abdominal fat was lost, regardless of the diet. These data suggest that more people should be considering a low-carb diet as a viable option, especially since it results in greater abdominal fat loss."

Approximately half of all American adults are estimated to be overweight, with a body mass index, or BMI, of 25 or higher; a third are estimated to be obese, with a BMI of 30 or higher. The effect of having too much weight on cardiovascular health and diabetes risk is even greater if there is a high accumulation of fat in the abdomen, above the waist. The Atkins Diet is designed to "flip the body's metabolic switch" from burning carbs to burning fat. Graduated carb introduction helps avoid blood sugar and insulin spikes, which cause hunger and cravings resulting in overeating and weight gain. Atkins provides a long-term, well-balanced diet plan that teaches individuals to find their personal ideal carb balance. No other weight-loss and maintenance program does this. The Atkins Diet is backed by more than 80 published, peer-reviewed studies conducted over the past several decades.

A study in 99 American men demonstrated that a high total fat intake is linked to lower total sperm count and concentration. It also showed that men, who consumed more omega-3 polyunsaturated fats, i.e. fats found in fish and plant oils, had better formed sperm compared with those who ate less of these fats. The researchers warn however, that the findings need to be supported by further research to validate the impact of fats on men's fertility given that this study was only performed in a small number participants.

Professor Jill Attaman, Clinical and Research Fellow in Reproductive Endocrinology and Infertility at Massachusetts General Hospital and an Instructor in Obstetrics, Gynecology and Reproductive Biology at Harvard Medical School declared:

Even though numerous earlier studies of the association between body mass index (BMI) and sperm quality have produced mixed outcomes, little knowledge exists regarding the potential impact of dietary fats on sperm quality.

Prof Attaman and her team decided to evaluate whether dietary fats affect sperm quality in 99 men attending a fertility clinic, between December 2006 and August 2010. The team first surveyed the participants about their diet after which they analyzed the men's sperm samples, including measuring the levels of fatty acids within the sperm. They also measured seminal plasma in 23 of the 99 participants.

The participants were then split into three groups based on their consumed fat intake. The researchers found that the sperm count was 43% lower, with a 38% lower sperm concentration in the highest fat-intake group than the group with the lowest fat intake. The team defined the 'total sperm count' as the overall number of ejaculated sperm and the 'sperm concentration' as the concentration of sperm in number per unit volume.

According to the World Health Organization, a "normal" total sperm count should contain at least 39 million sperm in the ejaculate, whilst the concentration of spermatozoa should contain a minimum of 15 million per ml. The study showed that the link between dietary fats and sperm quality was largely affected by the consumption of saturated fats, i.e. participants who consumed the most saturated fats had a 35% lower total sperm count and a 38% lower concentration of sperm compared to men who ate the least fat.

When it comes to managing children's obesity, cutting portion sizes and cutting carbohydrates can work equally well -- though carb control is tough for many kids, a new clinical trial finds.

If there were a "Saturday Night Live" skit that sums up Kevin Roberts' life, it would have to be The Loud Family. "My family is full of loud talkers," says the 42-year-old author and educational consultant from Detroit.

Many adults have tried to win the battle of the bulge by shunning carbohydrates, especially highly refined or starchy carbs like white bread and potatoes.

But much less has been known about how those eating plans work for kids, including whether they are safe and nutritionally sound -- since low-carb diets tend to be relatively high in fat.

For the new study, researchers randomly assigned 100 obese 7- to 12-year-olds to one of three eating plans: one that followed the conventional wisdom of portion control; a low-carb diet; or a "reduced glycemic load" plan that cut down on certain carbs that typically cause surges in blood sugar -- like white bread, sweets and white potatoes.

Over one year, all three plans worked equally well in controlling kids' weight gain. The difference, researchers found, was that the low-carb plan was tough to stick with.

"All of these plans can work," said lead researcher Shelley Kirk, of the Heart Institute at Cincinnati Children's Hospital Medical Center.

"But the low-carbohydrate one was really challenging for kids to follow," Kirk told Reuters Health. The diet still helped control kids' weight, she said, because they followed it to an extent -- reducing carbs and calories, but not to the strict limits of the low-carb plan.

All of that, Kirk said, suggests that a modified version of low-carb could work well for at least some kids.

Low-carb diets help obese kids but tough to follow

NEW YORK (Reuters Health) - When it comes to managing children's obesity, cutting portion sizes and cutting carbohydrates can work equally well -- though carb control is tough for many kids, a new clinical trial finds.

Many adults have tried to win the battle of the bulge by shunning carbohydrates, especially highly refined or starchy carbs like white bread and potatoes.

But much less has been known about how those eating plans work for kids, including whether they are safe and nutritionally sound -- since low-carb diets tend to be relatively high in fat.

All of that, Kirk said, suggests that a modified version of low-carb could work well for at least some kids.

And the diet based on reduced glycemic load was essentially that: Certain carbs were "unrestricted" -- including fruit, vegetables low in starch and 100-percent whole grains. More limits were placed on starchy carbs, but they were still allowed.

Over one year, children in all three diet groups had similar improvements in their body mass index (BMI), a measure of weight in relation to height, after accounting for the fact that they were still growing.
