How do you know if your body needs more protein?
Swelling
. One of the most common signs that you’re not getting enough protein is swelling (also called edema), especially in your abdomen, legs, feet, and hands. A possible explanation: The proteins that circulate in your blood — albumin, in particular — help keep fluid from building up in your tissues.

.
What disease can you get if you don’t have enough protein?
Too little protein may cause changes in body composition that develop over a long period of time, such as muscle wasting. The most severe form of protein deficiency is known as
kwashiorkor
