1. You will not gain weight if you eat steak, because beef is rich in protein and amino acids. The composition is closer to the needs of the human body than that of pork, and can improve the body's disease resistance. The fat content of steak is lower than other meats, so eating steak will not make you fat. The arginine content in beef is higher than any other food. This makes it particularly effective for building muscle and enhancing strength. In the first few seconds of training, arginine is the source of fuel for the muscles, and the demand for protein is also relatively large.

2. The diet contains more vitamin b6. Beef contains enough vitamin b6, which can help enhance immunity and promote protein metabolism and synthesis. Beef contains carnitine. The content of carnitine and arginine in chicken and fish is relatively low, but the content of beef is high. Carnitine is mainly used to support fat metabolism and produce amino acids, which play an important role in muscle growth for bodybuilders.
