It's not that you can't eat it at all. Try not to eat. If you have to eat, choose sugar-free, low-calorie, low-fat snacks, and then strengthen exercise and eat reasonably. Fitness is mainly to reduce sugar in the body, consume fat, and then increase exercise. Obese people consume excess fat in their bodies through certain aerobic exercise, so they can eat a small amount of sugar-free and low-fat snacks, as long as they strengthen their exercise.
