Exercise for weight loss still requires eating.
During exercise, the body burns significant calories, which greatly aids weight loss. Many people combine exercise with dieting to lose weight faster. While calorie control is necessary, completely skipping meals is not advisable.
Exercising before or after meals for weight loss
Both pre- and post-meal exercise can aid weight loss, though exercising before meals is generally considered more effective.
Engaging in moderate exercise 1–2 hours before meals (i.e., on an empty stomach) is actually more effective. This is because glycogen levels are lower during fasting, prompting the body's regulatory system to prioritize glycogen for essential physiological functions. Exercising at this time forces the body to mobilize more fat reserves to meet energy demands, facilitating the breakdown of excess fat (especially postpartum fat) and yielding superior weight loss results compared to post-meal exercise.
When is the best time to exercise for weight loss?
Exercising two hours before meals yields the most effective weight loss results.
At this time, the body naturally responds by seeking to raise blood sugar levels. To achieve this, it secretes a hormone called glucagon. In terms of fat-burning efficiency, glucagon actually functions somewhat similarly to adrenaline. It aids in fat breakdown and enhances the activity of fat-burning enzymes.
