Once we have described the general laws of our subject matter, we then proceed to try to explain those trends. Epling and Pierce postulated that excessive exercise prompts the body to produce a lot of beta endorphins, which suppress appetite and cause feelings of well-being, sometimes called the runner’s high. This, then, was their explanation for why rats become anorectic under their laboratory conditions. This may not help us explain the problem with humans; humans suffering from anorexia and bulimia have lower levels of beta endorphins.
