Background The effect of alternate day fasting (ADF) combined with endurance exercise (Ex) on body weight, body composition, and lipid levels, has never been tested. Objective Thus, this study examined whether the combination of ADF plus exercise produces greater changes in the above‐mentioned variables, when compared to each treatment alone. Methods Sixty‐four obese subjects were randomized to 1 of 4 groups: 1) ADF+Ex, 2) ADF, 3) Ex, or 4) control, for 12 weeks. Results Body weight was reduced (P < 0.05) by 7.1 ± 1.0%, 5.8 ± 1.0% and 1.4 ± 0.5% in the ADF+Ex, ADF and Ex group, respectively. Fat mass decreased (6.3 ± 1.5%, P = 0.001) and fat free mass increased (6.7 ± 2.3%, P = 0.015) in the ADF‐Ex group only. Waist circumference was reduced (P < 0.001) in all the intervention groups. LDL cholesterol decreased (7.0 ± 8.0%, P = 0.04) while HDL cholesterol increased (12.0 ± 10%, P = 0.04) in the ADF‐Ex group only. Conclusion These findings suggest that the combination of ADF plus exercise is the most effective treatment in reducing body weight, and improving body composition and plasma lipids, when compared to each intervention alone.
