In addition to indulgence and infidelity, there are also light meals. The concepts of indulgence meal and cheating meal are slightly different. Indulgence meal refers to choosing a diet with relatively high calorie, high fat, high sugar and high salt in the diet plan, usually to satisfy taste buds or adjust mood. Cheating refers to choosing a diet with low calorie, low fat, low sugar and low salt in order to lose weight, but it contains some high-calorie foods to cheat the body to reduce fat consumption. Skipping meals is a way to reduce food intake regularly, usually to lose weight or control blood sugar. This kind of diet only needs a small amount of food in a certain period of time, which can help the body detoxify, reduce the burden on the stomach and reduce the desire for high-calorie food. So there are indulgence meals, cheating meals and light meals.
