lternate-day fasting: How good is it for your health?

lternate-day fasting: How good is it for your health?
Scientists report that fasting or eating half as much as usual every other day may shrink your fat cells and boost mechanisms that break down fats.

Consuming less calories and increasing physical activity is commonly what people do to lose weight and stay healthy. But some people prefer to adopt a diet which consists of eating as much as they want one day while fasting the next. On each fasting day, these people consume energy-free beverages, tea, coffee, and sugar-free gum and they drink as much water as they need. Eventhough a number of people claim that this diet, called alternate-day fasting (ADF), help them lose weight and improved their health, the effects on health and disease risk of ADF are not clear.

Krista Varady and his colleagues studied the effects of alternate-day fasting on 24 male mice for four weeks. To assess the impact of ADF on the health of the mice, the researchers not only tested mice that followed and didnt follow an ADF diet, but they also studied mice that followed the diet only partially: a group of mice consumed 50 percent of their regular diet every other day (ADF-50%) and another consumed 75 percent of their regular diet every other day (ADF-25%).

The researchers noticed that the mice that followed the complete ADF diet.........

Less than 3 percent of UK 11-year-olds take enough exercise

Less than 3 percent of UK 11-year-olds take enough exercise
Less than 3 per cent of UK 11 year olds are taking enough exercise, suggests research published ahead of print in the Archives of Disease in Childhood.

It is recommended that kids spend at least an hour a day doing some form of moderate to vigorous physical activity, in a bid to promote good health and stave off the risks of subsequent obesity and diabetes.

The scientists monitored the physical activity levels of more than 5,500 11 year olds in the South West of England over seven consecutive days between January 2003 and January 2005.

The children were part of the Avon Longitudinal Study of Parents and Children (ALSPAC), which has tracked the health of more than 14,000 children since birth.

Each child was kitted out with a special piece of equipment (accelerometer), worn on an elasticated belt, which recorded minute by minute the intensity and frequency of physical activity.

The scientists were especially interested in total levels of physical activity and the amount of moderate to vigorous exercise the kids were taking daily.

When the data were analysed, they showed that the children were around twice as physically active as adults, but they were not yet active enough.

Boys were more physically active than girls, and they were also more likely to engage in moderate to vigorous forms of activity.........

Correlation between GERD and obesity in females

Correlation between GERD and obesity in females
A group of researchers recently discovered an association between being overweightand a disease called gastro-esophageal reflux disease (GERD) in women.

This discovery was reported in the Sept. 14 issue of the World Journal of Gastroenterology by a research group led by Dr. Corazziari from the University La Sapienza of Rome. Dr. Corazziari has been a leader in the field of gastroenterology for a long time and published over 200 research articles and 20 professional books. He and his fellow scientists (with Dr. Piretta being the first author of this article) discovered that, compared to average population, overweight and obesity are risk factors for GERD in women and not so much in men.

GERD is a disease with chronic symptoms or mucosal damage produced by the abnormal reflux of gastric contents into the esophagus. Heartburn (burning discomfort behind the breastbone) is the major symptom of GERD because the gastric acid gets into esophagus.

It is known that fatty foods produce a prolonged inhibitory effect on the lower esophageal sphincter (LES), especially following intra-duodenal lipid perfusion, but this inhibitory effect would appear due to a cholecystokinin-mediated action on LES. An epidemiological study revealed that overweightedness, but not excess fatty food intake, increases the risk of hospitalisation for GERD. Gastric distention following a copious meal also relaxes LER and increases the possibility of GERD.........

Children who learn heart healthy eating habits

Children who learn heart healthy eating habits
A new study in a mid-August edition of Circulation: Journal of the America Heart Association confirms that when young children learn about heart healthy eating habits, it can strongly influence their heart disease risk during the later part of life.

Results from the Turku Coronary Risk Factor Intervention Project have landmark implications on how children should be taught to eat. In this study, a childs fat intake, primarily reduction in intake of saturated fat, was found to be one of the greatest influencing factors, as per the research.

The publication of this study is timely since September 2007 is National Cholesterol Education Month, sponsored by the U.S. National Heart, Lung and Blood Institutes National Cholesterol Education Program.

Harri Niinikoski, M.D, Ph.D, lead author and a pediatric endocrinologist at the University of Turku in Finland, says: The aim of the diet counseling in our study was not to reduce the total number of fat calories in the diet, but to shift the childs intake from saturated toward unsaturated fats and have cholesterol intakes of less than 200 mg (such as the use of more vegetable oils than animal fats and butter.) .

Key dietary changes in the intervention families included: 1) using soft margarine and liquid oils instead of butter to maintain adequate fat intake while lowering consumption of saturated fat and cholesterol, and 2) appropriate adjustments to the type of milk consumed by the children.........

UI professor identifies new eating disorder

UI professor identifies new eating disorder
A University of Iowa professor is making a case for a new eating disorder she calls purging disorder.

The disorder is similar to bulimia nervosa in that both syndromes involve eating, then trying to compensate for the calories. What sets the disorders apart is the amount of food consumed and the way people compensate for what they eat. Women with purging disorder eat normal or even small amounts of food and then purge, often by vomiting. Women with bulimia have large, out-of-control binge eating episodes followed by purging, fasting or excessive exercise.

"Purging disorder is new in the sense that it has not been officially recognized as a unique condition in the classification of eating disorders," said Pamela Keel, associate professor of psychology in the UI College of Liberal Arts and Sciences, "But it's not a new problem. Women were struggling with purging disorder long before we began studying it".

In a paper published this week in the Archives of General Psychiatry, Keel shares the results of a study indicating that purging disorder is a significant problem in women that is distinct from bulimia.

Keel recruited participants for three groups: women without eating disorders; women who purge to compensate for binge episodes; and women with purging disorder who purge to control their weight or shape but do not have binge episodes. Participants came from the Boston and Iowa City/Cedar Rapids areas and were within a healthy weight range. The women completed self-report questionnaires and clinical interviews. They also had blood drawn before and after consuming a liquid test meal and reported their feelings throughout the meal, including feelings of fullness, hunger, sadness or tension.........

You're likely to order more calories at a 'healthy' restaurant

You're likely to order more calories at a 'healthy' restaurant
An important new study from the Journal of Consumer Research explains the American obesity paradox: the parallel rise in obesity rates and the popularity of healthier food. In a series of four studies, the scientists reveal that we over-generalize healthy claims. In fact, consumers chose beverages, side dishes, and desserts containing up to 131% more calories when the main dish was positioned as healthy.

In our black and white view, most food is good or not good, explain Pierre Chandon (INSEAD, France) and Brian Wansink (Cornell University). When we see a fast-food restaurant like Subway advertising its low-calorie sandwiches, we think, Its OK: I can eat a sandwich there and then have a high-calorie dessert, when, in fact, some Subway sandwiches contain more calories than a Big Mac.

In one study, Chandon and Wansink had consumers guess how a number of calories are in sandwiches from two restaurants. They estimated that sandwiches contain 35% fewer calories when they come from restaurants claiming to be healthy than when they are from restaurants not making this claim.

The result of this calorie underestimation" Consumers then chose beverages, side dishes, and desserts containing up to 131% more calories when the main course was positioned as healthy in comparison to when it was noteven though, in the study, the healthy main course already contained 50% more calories than the unhealthy one.........

Surgery for severe obesity saves lives

Surgery for severe obesity saves lives
An extensive swedish study from the Sahlgrenska Academy has established that surgery reduces premature death in patients with severe obesity. A long-term follow up has shown that mortality is significantly lower among patients who undergo surgery than among those who do not.

The results are published recently in The New England Journal (NEJM).

We show for the first time that surgery against obesity not only leads to long-term loss of weight, it also significantly reduces mortality", says Lars Sjstrm, professor emeritus at the Sahlgrenska Academy, located in Gteborg in Sweden.

Over 4,000 severely obese patients were included in the study, which Lars Sjstrm started as long ago as 1987. Half of these patients underwent stomach surgery (bariatric surgery) intended to give weight loss. The remaining patients received advice concerning lifestyle changes, also intended to give weight loss. Some of these patients also received medicines for weight loss, but even so, the conventional therapy was considerably less effective than the surgical procedure.

The group receiving conventional therapy had even increased somewhat in weight after 10 years, while patients who had undergone surgery decreased in weight by 16%, on average. Bariatric surgery is the only therapy for severe obesity for which there is scientific evidence that it reduces mortality", says Lena Carlsson, professor at the Sahlgrenska Academy.........

Women lose weight before developing dementia

Women lose weight before developing dementia
Women who have dementia start losing weight at least 10 years before the disease is diagnosed, as per a research studyreported in the August 21, 2007, issue of Neurology, the medical journal of the American Academy of Neurology.

The scientists examined the records of 481 people with dementia and compared them to 481 people of the same age and gender who did not have dementia. The average weight was the same for those in the two groups from 21 to 30 years before the year the disease was diagnosed. But the women who would later develop dementia started losing weight up to 20 years before the disease was diagnosed. On average, those with dementia weighed 12 pounds less than those without the disease the year the disease was diagnosed.

One explanation for the weight loss is that, in the very early stages of dementia, people develop apathy, a loss of initiative, and also losses in the sense of smell, said study author David Knopman, MD, of the Mayo Clinic in Rochester, MN, and member of the American Academy of Neurology. When you cant smell your food, it wont have much taste, and you might be less inclined to eat it. And, apathy and loss of initiative may make women less likely to prepare nutritious meals and more likely to skip meals altogether.

Unlike women, men in this study who later developed dementia did not lose weight in the years before diagnosis. Knopman said the difference could be due to hormones, but a social reason seems just as likely.........

Fat still on the children's menu

Fat still on the children's menu
Parents should think twice before offering a low-fat menu to youngsters, despite concerns over obesity. Children burn more body fat than adults for each calorie spent, as per research in the online open access publication, Nutrition Journal, evidence that fat can be included as part of a childs healthy and balanced diet.

A US team led by John Kostyak from The Pennsylvania State University used calorimetry to measure whole body fat oxidation in 10 children (aged 6-10) and 10 adults. All had a body mass index (BMI) within the healthy, middle range. Kostyak's team checked subjects cardiovascular fitness and body fat, and all were given the same typical American diet for three days previous to testing (eventhough adults had larger portions). Test subjects spent nine hours on three separate days at a low physical activity level, watching movies or reading, in either a room calorimeter or under a hood system, which quantify oxygen and carbon dioxide gas levels. The authors also measured the total amount of nitrogen in the subjects urine, and used these measurements to calculate how much fat they oxidised.

Eventhough the absolute amount of fat burned in a day did not differ greatly between children and adults, children burned considerably more fat relative to the amount of energy they used. In an attempt to determine the contribution of fat oxidation to daily calorie expenditure, the scientists calculated the grams of fat oxidized per kcal of energy expenditure. This value was higher in children (0.047 0.01 g/kcal) in comparison to adults (0.032 0.01, p<0.02). Women and girls used fat at a higher rate than men and boys of a comparable age.........

Obesity, lack of exercise and pancreatic cancer

Obesity, lack of exercise and pancreatic cancer
Obesity and aversion to exercise have become hallmarks of modern society and a new study suggests that a blood protein associated with these lifestyle factors may be an indicator for an increased risk of developing pancreas cancer. Scientists from the Dana Farber Cancer Institute report their findings in the August 15 issue of Cancer Research, a journal of the American Association for Cancer Research.

In a study of 144 patients with pancreas cancer and 429 people without the disease, a subset of patients with low blood levels of a protein called IGFBP-1 were at approximately twice the risk of developing pancreas cancer. Low blood levels of this protein have previously been associated with excess weight and lack of physical activity. Their data originated from tens of thousands of men and women enrolled in four large-scale cohort studies the Health Professionals Follow-Up Study, the Nurses Health Study, the Physicians Health Study and the Womens Health Initiative Observational Study all of which followed the health of participants over numerous years.

The prognosis for a number of patients with pancreas cancer remains poor, so it is vitally important that we indentify and better understand risk factors for the disease, especially risk factors that are modifiable said lead study author, Brian M. Wolpin, M.D., attending doctor at Dana Farber Cancer Institute. In addition to cigarette smoking, exercise and weight control appear to be important modifiable risk factors for this difficult disease.........

Did you know?
Exercise can't stop the aging process, but experts at Baylor College of Medicine in Houston say that for the elderly, whether it's weight training, walking, swimming or biking, 30 minutes of exercise three to five times a week is a good prescription for aging."It's never too late to start exercising," said Dr. Robert Roush, an associate professor of medicine-geriatrics at BCM. "Being physically active and exercising regularly can help prevent or delay some diseases and disabilities as people age.".
