(1) Fitness enthusiasts who rely too much on special nutrition supplements and ignore normal diet often pay more attention to special nutrition supplements and ignore the basic role of normal diet nutrition, resulting in unreasonable nutrition intake in basic diet. Special nutrition can't replace normal diet. If you blindly pursue special nutrition and buy a lot of supplements such as amino acids and protein powder, it will not only have no good effect, but also cost a lot of money.

(2) The diet emphasizes the excessive intake of protein, but ignores the intake of sugar. Many people may still think that meat is nutritious. If bodybuilders only pay attention to meat intake and ignore the basic role of staple food in diet, it will not have good results. Because sugar is the main energy source during exercise, if the sugar supply is insufficient, the body will consume protein to provide energy. This is a waste of protein, and it can't achieve good results.

(3) Want to quickly increase muscle volume in a short time. The increase of muscle mass is not achieved overnight, but a gradual process. The ideal goal of muscle gain is to gain about 0.45 kg per week.
