Children�s Belly Fat Increases More Than 65 Percent
Abdominal obesity increased more than 65 percent among boys and almost 70 percent among girls between 1988 and 2004. The finding of growing girth is significant because abdominal obesity has emerged as a better predictor of cardiovascular disease and type 2 diabetes risk than the more commonly used Body Mass Index, a weight to height ratio that can sometimes be misleading.

Link between short sleep duration and obesity uncovered
Soaring levels of obesity might be linked to children sleeping fewer hours at night than they used to, claims Dr Shahrad Taheri of the University of Bristol. Dr Taheri, reporting in the Archives of Disease in Childhood, blames the increasing availability of computers, mobile phones, TVs and other such gadgets on the diminishing nightly quota of sleep, and suggests they should be banned from children's bedrooms.

'Portion Distortion' may contribute to expanding waistlines
New research shows that people's perceptions of normal portion sizes have changed in the past 20 years. A study out of Rutgers published in the September issue of the Journal of the American Dietetic Association reports that Portion Distortion may be the cause1. This phenomenon occurs when consumers perceive large portion sizes as appropriate amounts to eat at a single eating occasion.

BMI is an unreliable indicator of obesity
Body mass index (BMI) -- the commonly used measure of obesity - cannot reliably predict the outcome for patients with heart disease, concludes an Article in this week's issue of The Lancet. This is because BMI is an unreliable indicator of obesity, say the researchers. Doctors already know that obesity is a risk factor for developing heart disease. However, how obesity affects people with established heart disease has been unclear because previous studies have had contradictory results.

Exercise important in reducing size of abdominal fat cells
Reducing the size of abdominal fat cells � which are a risk factor for diabetes and heart disease � takes more than cutting calories, according to new research from Wake Forest University Baptist Medical Center. Early results from a five-year study show that exercise should be added to the equation.

High BMI doesn't always spell obesity
For years doctors have used the body mass index (BMI), a ratio of height and weight, to characterize the clinical weight status of their patients. The lower the number, the presumption goes, the leaner the person, and anyone with a BMI above 30 is characterized as obese and at high risk for the associated complications.

Health Risks in Obesity are Underestimated
The health risks for women who are extremely obese may be underestimated as a new study indicates they have a higher prevalence of hypertension, diabetes, and high cholesterol than women at lower levels of obesity, according to a study in the July 5 issue of JAMA. Obesity diagnosis and treatment are typically based on body mass index (BMI) of at least 30. BMI is calculated as weight in kilograms divided by height in meters squared. However, three categories of obesity are defined: obesity 1 (30-34.9); obesity 2 (35-39.9); and extreme obesity (40 and greater). (A 5�4� person would have a BMI of 40 if they weighed 233 lbs). The latter 2 categories, sometimes termed severe obesity, are reported to be increasing especially rapidly in the United States, according to background information in the article. From 1986 to 2000, prevalence of BMI of 30 or higher approximately doubled, while that of BMI of 40 or higher quadrupled and that of BMI of 50 or higher increased 5-fold. In 2000, 2.8 percent of all U.S. women, and 6 percent of black women reported measurements consistent with extreme obesity. Estimates of obesity-related risks in women have generally been based on weight data that preceded the increase in extreme obesity. It has been unclear whether health risk increases or plateaus as body weight increases throughout the obese range.

New study shows some people just can�t resist food
Scientists have discovered why some people�s brains are particularly vulnerable to food advertising and product packaging, putting them at risk of overeating and becoming overweight. The research provides fresh insight into one of the neurobiological factors underlying obesity by showing how some people are more attracted to the prospect of being rewarded with tasty food than others. The findings from a group of scientists at the Medical Research Council�s Cognition and Brain Sciences Unit in Cambridge led by Andy Calder and Andrew Lawrence are published in the Journal of Neuroscience.

Dairy is not associated with weight gain - Research
Calcium intake was not associated with weight gain in men over a 12-year period, according to a new study published in the American Journal of Clinical Nutrition1. The study included more than 19,000 healthy men aged 40-75 years who were enrolled in the Health Professionals Follow-up Study. The researchers evaluated the relationship between total calcium intake from diet and supplements and changes in body weight based on self reported weight at the beginning and end of the 12-year study period. Study participants followed their normal diets, not calorie-restricted diets.
