[size=45]Protein is an essential macronutrient that serves many functions in the body.
The recommended amount of protein is 0.37 grams per pound of body weight, or 0.8 g/kg (1).
However, physically active individuals need 0.6–0.9 grams per pound, or 1.4–2 g/kg (1, 2).
Research shows that high-protein diets also help with weight loss (3).
The simplest way to increase your protein intake is to eat more high-protein foods.
That being said, not all high-protein foods are equal. Some of them are extremely high, almost nothing but protein and water.
