The principle of muscle growth is to slightly destroy muscle fibers through resistance movement. When protein and amino acids are used as "raw materials" to repair damaged fibers, the repaired muscles will be stronger and grow. Oats do not contain protein and amino acids, while protein and amino acids are the "raw materials" needed for muscle growth. Oats are mainly composed of carbohydrates, although they are also a kind of energy that the human body needs. But not suitable for muscle gain.

Oat is suitable for people who need to lose weight, because it contains low carbohydrate content, which makes people feel full after eating and is suitable for reducing fat.
