Let's talk about the principle of muscle growth: muscle and fat are different. Fat means that as long as you eat more, calories will accumulate and turn into thick fat. Although there are a lot of protein in muscles, you can't gain muscle just by eating protein. Protein is just a green leaf. The most important thing is to keep practicing in order to have enviable muscles!
During muscle training, every muscle fiber will swell and eventually tear, and then protein will be added to repair and increase the fiber volume. This is called muscle augmentation, so it is useless to supplement the latter without the tearing of the former!
Supplementing protein helps to reduce the accumulation of fat. Especially beef, which is low in fat and high in protein, can be enjoyed to the fullest. Protein's supplement can reduce the intake of fat, so that we can fully burn fat while gaining muscle.
Second, even if you are a muscular Iron Man, you can't eat too much protein. You must calculate according to your training volume and weight. A scientific diet will make your training more effective. After training, we need to supplement not only protein, but also some fruits and vegetables. Some people eat too much protein, which leads to diarrhea. The main reason is acid-base imbalance.
There is no natural muscle, no natural fat, and everyone's efforts are the key to determining your figure. Fat is caused by irregular life, and muscle growth depends on your persistence and hard work every day. This is not born, nor is it given by parents, so recognize the reality! You can't grow muscles just by eating protein! Eating meat doesn't necessarily grow meat, the scientific method is the truth!
