Time magazine reports on a New England Journal of Medicine study: simply limiting calorie intake may be the most effective way to lose weight. This should be pretty intuitive but a whole $40 billion dollar industry has sprung up around the idea that you can just eat certain types of foods to lose weight according to different theories. We still don't really have a pill that makes you lose weight with no side effects. Bariatric surgery is safer and has positive effects on glucose regulation but still requires general anesthesia. A simpler option: portion control. Smaller plates less snacking. This is the technique of Weight Watchers which is why I continue to recommend it to my patients. The point system is really just a way to keep track of calories and fat. http://news.yahoo.com/s/time/20090226/hl_time/08599188179500
