Now that you mention the healthy eating plan, I think you have requirements for yourself, which is very rational. Boys don't have to be too rigid in their diet, just grasp a scale. For example, three meals a day can follow the traditional principles of good morning, full stomach and less lateness, and dishes can be matched with vegetarian dishes according to taste, and they should be moderately diverse. Avoid eating a lot for a long time, drink plenty of water, choose more tea suitable for taste and stomach, try to be punctual for three meals, and avoid midnight snack and overeating.
Before, it was diet, and exercise was also very important. You don't have to join a health club. You can appropriately increase outdoor exercise, find a suitable exercise, and stick to it for a long time. Let's go. It's not bad to ride a bike.
If you want to be hard, you need training. It's best to get the guidance of a professional fitness coach, and don't get sports injuries.
In short, healthy diet and exercise are long-term, and it is best to follow them for a lifetime.
