Comparison of weight loss on low-calorie (800-1200) and very-low-calorie (300-600) diets.
Conventional food diets of 300-600 kcal (14-20 days) were not as efficient as anticipated in increasing the rate of weight loss in ten obese patients previously given diets of 800-1200 kcal (13-30 days). The greatest efficiency was 76 per cent of the theoretical. The final weights after refeeding the 800-1200 kcal diets (9-14 days) were 0.5-2.0 kg greater than expected to result from the increased caloric deficit, and close to the weights that would have been reached had the 800-1200 kcal diets been continued without increased reduction in caloric intake.
