Problems of Calorie Restriction

Restricting calories as a means of losing body weight is the most common approach used in the weight-loss industry and by individuals, especially athletes. About 95 percent of those who go on a calorie-restricted diet will fail in the long run. Endurance athletes often count calories to reduce or avoid too much body fat. By restricting calories, runners, cyclists, swimmers, and others risk not supplying sufficient energy for optimal training.

Of those who lose weight initially with calorie restriction, most will gain it back—plus more—in the end. Moreover, most will not lose body fat. Much of this problem is due to the fact that by restricting calories, one’s metabolism is adversely reduced, with the result of eventually storing more body fat.

By performing a computerized dietary analysis on almost every patient I’ve seen in practice, I noticed that most of them who restricted calories also restricted nutrients. This results in a loss of health and athletic performance. Dehydration, nutrient loss, muscle and bone loss, lowered metabolism that shifts to more sugar and less fat burning, and other health issues are most often the real result of weight loss from calorie restriction. In some, the result has been an eating disorder that can be even more difficult to treat.
