It can be seen that beef with the same weight has lower calories than chicken breast, and the proportion of nutrients is more suitable for bodybuilders.

In addition, eating more beef has several other benefits:

Increase training time:

Beef is rich in nutrient-rich sarcosine. As one of the sources of muscle energy, sarcosine can help to supplement adenosine triphosphate, so that the fitness time can last longer and fatigue will not be easily felt.

Beef is rich in alanine. When carbohydrate intake is insufficient, alanine can provide energy for muscles in time, and alleviate the physical decline caused by insufficient energy supply.

There is also vitamin B 12, which can promote the metabolism of branched-chain amino acids and provide energy for muscles during high-intensity training.

Helps to exercise muscles:

Beef is rich in carnitine, much more than other meat products. Carnitine participates in the metabolism of fat and produces branched-chain amino acids, which is of great help to gain muscle.

And other nutrients such as potassium, zinc and magnesium that are rich in beef. ...

When the potassium content is low, the human body will inhibit the synthesis of protein and the production of growth hormone, thus affecting the muscle gain efficiency.

Zinc is an antioxidant, which contributes to the synthesis of protein.

Magnesium can promote protein synthesis, help muscle growth and improve the efficiency of insulin synthesis and metabolism.

Iron is an essential mineral for hematopoiesis.
