Here's a little insight into long-term dieting from the journal Nutrition & Metabolism. Researchers recruited 58 male and 72 female overweight subjects and had them stick to a diet reduced by 500 calories per day for 1 year. Half consumed 1.6 grams of protein per kg of body weight per day (about 161 grams for a 180 pound person), while the rest got just 0.8 grams, or 66 grams for that same 180 pound subject.
Males lost about the same amount of weight as females, approximately 10% of their original body weight, and there were no weight loss differences between high protein and high carbohydrate diets. But there were significant differences in body fat loss.
The high protein diet was much more effective at reducing the amount of body fat. Men tended to lose fat in the mid-section more easily than women, but they typically carry more weight in the abdominal area. Women tend to have more fat in their legs, but lose is at about the same rate as men. For Breaking News on a popular weight loss supplement, visit optimumnutrition.com
