A new study finds obese people have 8 percent less brain tissue than normal-weight individuals. Their brains look 16 years older than the brains of lean individuals, researchers said today.
Those classified as overweight have 4 percent less brain tissue and their brains appear to have aged prematurely by 8 years.
The results, based on brain scans of 94 people in their 70s, represent “severe brain degeneration,” said Paul Thompson, senior author of the study and a UCLA professor of neurology.
“That’s a big loss of tissue and it depletes your cognitive reserves, putting you at much greater risk of Alzheimer’s and other diseases that attack the brain,” said Thompson. “But you can greatly reduce your risk for Alzheimer’s, if you can eat healthily and keep your weight under control.”
The findings are detailed in the online edition of the journal Human Brain Mapping.
Dietary Supplement Influences Body Composition
More than one billion human adults worldwide are overweight and, therefore, are at higher risk of developing cardiovascular diseases, diabetes, and a variety of other chronic perturbations. Many believe that use of natural dietary supplements could aid in the struggle against obesity. So-called “starch blockers” are listed among natural weight loss supplements.
Theoretically, they may promote weight loss by interfering with the breakdown of complex carbohydrates thereby reducing, or at least slowing, the digestive availability of carbohydrate-derived calories and/or by providing resistant starches to the lower gastrointestinal tract.
The study found:
After 30 days, subjects receiving Phaseolus vulgaris extract with a carbohydrate-rich, 2000- to 2200-calorie diet had significantly greater reduction of body weight, BMI, fat mass, adipose tissue thickness, and waist,/hip/ thigh circumferences while maintaining lean body mass compared to subjects receiving placebo.
The results indicate that Phaseolus vulgaris extract produces significant decrements in body weight and suggest decrements in fat mass in the face of maintained lean body mass.
