Deficiency of both qi and blood will make you thin. Stewed chicken with astragalus and angelica won't get fat. Being fat is not a sign of health, so is being thin. Being thin is not equal to being healthy. It may be spleen deficiency or kidney deficiency. I just want to say that even if you use this chicken soup, you will be healthy and fat, and you won't keep getting fat. Obviously, it's not chicken or chicken soup that makes you fat, but angelica.
