ABSTRACT
Ten obese children aged 8-13 years participated in a 4-week program of weight reduction. Dietary restriction of 800 kcal/day and mild exercise were the two features of the program. With this regimen the investigators expected that their lean body mass would be preserved while body fat would decrease. After the 4-week program, we found that those who were mildly and moderately obese lost more than 5 per cent of their body fat but less than 1 per cent of lean body mass. Those children with morbid obesity lost more than 5 per cent of body fat and lean body mass. It is concluded that the regimen is suitable for mild and moderate obesity, but for morbid obesity, a new regimen with higher energy and higher protein in the diet may be more suitable than the current one.
