Men and women have different constitutions. For men, three meals a day is normal. Eating more food will not only enhance physical fitness, but also increase the burden on the digestive system, affecting gastrointestinal function, which is not good for the body. Seriously, it will cause gastrointestinal dysfunction, which will only lose weight and is not good for the body. Women are better in this respect, but they should not eat too much and have no restraint.
The number of meals in the diet is a habit. In rural areas, food was scarce in the past. In order to save time and attach importance to heavy physical labor, it is nothing unusual to eat only two meals a day for many years. Not heavy manual labor. Eating less dinner is not harmful to your health. It's just that I will feel uncomfortable for a few days at first, and I should get used to it. Under the condition of ensuring normal nutrition, properly reducing the number of meals can reduce the burden on the stomach and be beneficial to health.
