I started exercising recently. What should I eat during this time and how to arrange my diet?

Recently, I started full-body exercise. Before that, I consulted a lot of materials and summarized the following points. First, I want to concentrate on exercising a certain part for 45 minutes, which can be divided into several intervals. The rest time for each class shall not exceed 5 minutes. Second, it's best to let my body replenish protein within 45 minutes after exercise. Protein is the necessary food for the fastest muscle growth. Such as eggs, milk, preferably beef. As for what can reduce muscle, I personally think it is fatty food. Everyone knows that being fat means being fat. For example, I have been exercising for a month, and my grades feel good, and my muscles have really increased a lot. The following is my diet for the whole day. I eat milk and bread in the morning and an apple an hour before lunch. It doesn't matter what I eat for lunch, but at least I have a bowl of meat and a dish. Start 45 minutes of local exercise 2 hours after lunch, drink a glass of milk and eat an egg after exercise. Dinner is light. Do 45 minutes of local exercise hours before going to bed, and drink a glass of milk after exercise. Then brush your teeth and go to bed. I used to be thin, but now I am strong and tall. Oh, I am 23 years old. I hope these will help you a little.
