At the beginning of fitness, because the amount of exercise is not large, we just need to supplement enough protein through diet. With the increase of training, the body's demand for protein increases. At this time, there are two ways. One is to adjust the diet and increase high-protein foods, such as eggs, milk and meat. The other is protein powder.

Compared with diet, protein powder has three advantages. First, it is convenient to eat. Protein's supplement must be that it is a bit difficult to finish a meal within half an hour after training, and it is very simple to brew a cup of protein powder; Second, the price is cheap. High-protein foods are mainly meat, eggs and milk, which need to be eaten in large quantities for fitness. If converted, protein powder is more cost-effective; The third is good absorbability. The nutrition in protein powder is purer and better absorbed.

So people who exercise can eat like this, drink a cup of protein powder for half an hour after exercise, and then eat meat, vegetables and staple food at night. It is best to use coarse grains instead of polished rice, which can provide more nutrition.
