Summary

Introduction: It is known that weight loss results in decreased Resting Energy Expenditure (REE), due to a decrease in lean body mass (LBM), but also due to metabolic adaptation, resulting in a higher energy efficiency, responsible for weight regain. Powerlifting athletes submit themselves to caloric restriction before a competition to reach their desired weight category. After cessation of the restrictive diet body mass will quickly return to pre-diet values with a disproportionate gain of fat mass. To avoid fat gain 'reversed dieting' has become popular among athletes. This involves increasing caloric intake in a stepwise fashion with the assumption that the small increases in caloric intake might help to restore energy expenditure toward pre-dieting levels and decrease the chance of increasing fat mass. While anecdotal reports of successful reverse dieting are available, research is needed to evaluate its true efficacy. In addition, if the method would work in non-athletes this could be an important change in the risk of weight regain after a weight loss diet. .

Aim: To test the effects of the reverse dieting protocol in the prevention of metabolic adaptation following a period of caloric restriction in weight training athletes. .

Methods: A convenience sample of 3 powerlifters is used in this study. They are submitted to a 750kcal/day caloric deficit with a protein intake set at 2x bodyweight (kg) and 30%en from fat for 6 weeks, adjusted weekly. The reverse dieting protocol adds 100kcal during week 1-4 and 150kcal during week 5-8. REE is measured bi-weekly and body composition at day 1 of caloric restriction and day 1 and day 56 of reverse dieting. Exercise is kept constant during the entire period. .
