Sorry to interject, but the engineer in me can't get past this. I agree with this statement 110%! The correct equation is Energy In = Energy Out + Energy Stored :yes: I disagree with this statement.. well sort of. For "the regular joe".. sure. HOWEVER, as a blanket statemnt.. I don't think it is true if you follow conservation of energy. AS an example, if you believe what Michael Phelps says he eats when he is training hard combined with swimming a lot, he most certainly "over eats" per any definition we can come up with.. He works it off.
