Research shows that if your body is not taking the protein it needs from food, it starts breaking down muscle proteins to maintain its function (2).
It can be difficult to get enough protein for a low-calorie diet. “If you have too many calories, your body will betray you!” says Jaeger.

In other words, if your goal is to build a lean mass, you may not be able to see the outcome you want.
You get tired for no reason
Proteins make up hemoglobin, a component of red blood cells that carry oxygen throughout the body. This literally gives you the energy you need to live! If your body does not have enough protein to make hemoglobin, you may experience fatigue Or, in severe cases, anemia (4).
