The arrangement of meals is often decided according to one's living and working habits, and there is no strict determination of how many meals to eat a day. But for the sake of health, the law of life is necessary, and three meals a day are basically guaranteed. For thin friends who are busy with life and work, it is also a good way to gain weight by keeping some small foods around them, such as fruits, yogurt and cakes, in case they can't eat on time.
At the same time, we should eat less and eat more meals at ordinary times, with 70% fullness per meal, high starch, low fat and many fruits, which can supplement some basic nutrition such as protein, vitamin B, vitamin C and calcium-magnesium tablets. In this way, after a period of conditioning and physical strength enhancement, you will successfully gain weight.
