Most effective enforced exercise time for aerobic exercise to burn body fat

Abstract

Physical exercise is important to limit fat mass and prevent obesity. Of four studied exercise times, aerobic exercise before lunch (4 h after breakfast) was most effective in reducing body fat. This reduced the rate of body fat 1.20 times more than exercise after breakfast, 1.63 times more than after lunch, and 1.30 times more than before dinner (P < 0.01). Exercise before lunch used the most blood sugar, thereby consuming body fat. The difference between exercise before lunch and before diner might be explained by the metabolic efficiency of the body rhythm. This study used four stages of exercise intensity. At any of the four exercise times, the mildest intensity exercise (20% increased heart rate) was effective in reducing body fat. For women who do not exercise regularly, continuous slow movement on an empty stomach may reduce body fat.
