A small amount of low-calorie stuff after occasional exercise usually won’t make you gain weight. If you eat a lot of high-calorie things after long-term exercise, you may gain weight.
Obesity is a long time, day after day, so whether eating after exercise will be fat needs to be based on the frequency of eating, how much to eat, eat the food to judge. If you eat occasionally after exercise, and eat food belongs to low-fat, low-calorie food, while not much intake, generally does not lead to fat.
If you eat after exercise for a long time and eat a lot of high-calorie, high-fat and high sugar content food, it may lead to fat accumulation in the body, which may cause obesity in the long run.
It is recommended that people during weight loss need to control the amount of calories they consume each day and eat less calorie-rich food after exercise.
