Dr. Ted is incorrect. "Dropping below 15% protein risks Kwashiorkor – it’s the reason why those starving kids in the television commercials have fat bellies – lack of protein actually causes more fat to be deposited!"
More fat is not deposited. [A swollen belly in these cases is a symptom of] edema (fluid) that collects in the abdomen or feet. It comes from the capillaries when there is a lack of protein in the diet and the liver cannot produce enough albumin. Thus the blood is hypo-osmotic and fluid is lost into the peritoneum, also called third-spacing. – J.W.M.
