At a time of fad diets and health crazes, the importance of protein in a diet is often ignored.  According to a recent study published in the New England Journal of Medicine, low-protein diets often result in a loss of lean body mass.1

 

High protein diets where individuals consume up to 200 grams of protein are popular in body-building circles, however current evidence is mixed as to whether unusually large amounts of protein help to increase lean muscle mass. What is clear though is that a moderate amount of protein is essential for maintaining a good balance of fat and muscle. When considering a vegan diet, it is even more important to ensure that adequate protein is consumed. Indeed, a higher volume of plant matter than meat must be consumed to ingest equivalent levels of protein.2
