  1. 1 Values are mean ± SD. Compared using an unstructured repeated measures model, α = 0.05, with no adjustment for multiple comparisons. 2 Weight measured with a digital scale. 3 Measured with dual-energy X-ray absorptiometry (DXA). a Differs from males within time and diet. b Differs from baseline within diet and gender. CARB = higher carbohydrate diet. PRO = higher protein diet. 4 month = 4 months of weight loss intervention from baseline. 12 months = 4 months of weight loss and additional 8 months of weight maintenance from baseline.
