I didn't say much before, and I still do now, but I don't think it's necessary. Because all fitness people are fooled by businesses, they think that the repair and growth of muscles need a lot of protein, and even those who have doubts think that there is no harm in appropriately increasing protein. But when you think about it, muscles are actually 70% water. If you exercise hard for a month, you will gain 0.23 kg of muscle. How much protein do you need? As for repairing muscles, instead of replacing all muscles, do you need 1.5 to 2 grams of protein per kilogram according to your weight? Don't believe this lie. I only eat one egg to two eggs every day now, and I haven't seen any muscle loss yet. What's more certain is that businesses find people to write all kinds of soft articles, which has convinced all fitness people that muscles can't be separated from protein, so buying protein powder is the only way. I just want to tell you that adequate carbohydrates and balanced nutrition are the correct way to eat. You should know that 70% of the sugar that balances blood sugar in the human body comes from muscle. Muscle and bone are actually one of the warehouses of human body's reserve resources, and bone is the largest calcium bank. If you still don't believe me, you can think about it. During adolescence, you can grow more than ten kilograms of muscles without exercise. Have you ever consumed a lot of protein? Adequate staple food is the basis of glycogen storage. To increase strength, we must first increase glycogen storage. Muscle itself is a storehouse for glycogen. If you want to add more muscles to your body, you must convince your body that it is very important to increase glycogen storage instead of converting carbohydrates into fat. This is why after the training intensity exceeds a certain limit, the amount of training is the most important criterion to measure your muscle and strength increase.
