Well, no s**t, Sherlock! You just proved the point made in "Super Size Me."
So, the point of "Super Size Me" was that eating at MacDonald's is fine as long as you exercise?
Or was it that "If you eat more calories than you burn, you will get fat?"
Rumor control has it the the point was "Evil corporations conspire to make people unhealthy."
I haven't seen the film, so perhaps you could enlighten us as to which of the above is closest to being correct.
