Body composition and weight maintenance with a very-low-calorie diet for the treatment of moderate obesity.

We report body composition in 11 moderately obese patients (mean BMI less than 30) treated for 8 wk with a 2530-kJ/d (605-Kcal) diet. Mean weight loss was 9.4 kg. Fat-free mass (FFM) loss of 2.3 kg was 23% of total weight loss and essentially equal to loss of total body water (2.5 L). Body composition was measured by the Futrex-5000 near-infrared technique. We conclude there is no excess loss of FFM in moderately obese patients treated with MNP 70/70, a 70-g protein, 70-g carbohydrate dietary supplement for 8 wk.
