Research at Harvard Medical School suggests that the human body reaches a weight-loss limit about 12 weeks into any diet and then plateaus, refusing to lose another pound, at least for a while.
Our bodies, it appears, can’t stand to lose more than 5 to 10 percent of their weight at once. It’s best to take a rest for another 12 weeks, giving your body a chance to adjust to the weight loss. Don’t revert to high-calorie eating habits, but don’t strive to cut calories, either. Figure out some reasonable approach between the two. Then head into another 12-week dieting period and watch your weight drop anew.
