Is there a problem with eating a meal consisting only of protein?
By definition, a single macronutrient–be it protein, carbohydrates or fat–cannot entirely makeup a meal. it is not recommended that any primary meal (i.e. breakfast, lunch or dinner) be replaced with a single macronutrient. However, in lieu of skipping a meal, eating protein has several benefits over pure carbohydrates or fat. First, protein helps maintain the body’s metabolism via the digestive pathway. Second, it helps the body maintain a positive nitrogen balance, which helps prevent entering a catabolic state. Third, the human body is very resourceful in that it can convert protein into other macronutrients (i.e carbohydrates and fats) as necessitated by the body.
