1. Control the amount of food: the portion of each meal should be moderate, not too much nor too little. Generally speaking, three meals a day plus two or three snacks is enough.

2. Nutritional balance: In the case of eating less and eating more meals, we should pay more attention to the nutritional collocation of food. Every meal should contain protein, carbohydrates and fat to provide energy for the body.

3. Timing and quantification: Try to fix the time of each meal, which can help the body establish regular eating habits. At the same time, we should also pay attention to the amount of food eaten per meal to avoid eating too much at once.

4. Pay attention to the time of eating: try to avoid eating within two hours before going to bed, because this will easily lead to indigestion and weight gain. Breakfast should be rich, lunch can be reduced appropriately, and dinner should be as light as possible.

5. Keep hydrated: It is very important to keep adequate water intake during fitness. You can drink a glass of water between meals or add some electrolyte drinks after exercise.

6. Pay attention to your physical condition: If you feel full or uncomfortable, stop eating. At the same time, you should adjust your diet plan according to your physical condition. For example, if you are doing intensive training, you may need more protein to help your muscles recover.
