Two things TS.
First, you mean "this raises the question.." because begging the question is a form of logical fallacy in which a statement or claim is assumed to be true without evidence other than the statement or claim itself.
Second, "no!" Food also provides strength and allows fighters to heal. Your suggestion raises the equally stupid question (see how I did that?) of "should the UFC ban food and test for food consumption?"
I know you were trying to be glib and clever at the same time but you failed on both.
