The funny thing is, fatty food in itself is not nessecarily bad, it's whether you're ingesting foods that rank high on the glycemic index... After all, having your blood sugar spike too much causes an overproduction of insulin which will cause your fat cells to store energy and swell at a much greater rate, due to the effect of overstorage causing your body to not use the energy it consumes, which will in turn cause your energy level to drop as your metabolism slows due to all that insulin forcing the energy that would normally go to your organs and muscles to be used to go into fat storage instead, which compounds intoa near never ending cycle of lazyness, hunger that really shouldn't exist(mis representation of signals from the body telling your brain that you are hungry, when it's really just your body processing the food you have eaten incorrectly) therefor overeating, therefor overloading with nonessencial calories, and making you fat and tired.
When you eat at a fast food place, it's not the burger that's doing the damage, it's the sugary soft drink and the processed simple carbohydrate rich fries that do it, not the fat...
but I can see how someone who's studying the effects of media violence might not exactly know much about nutrition or biology... so it can be forgiven to some extent.
I would just think that it might be a little more poignant if he had referenced something he actually knew something about as an example, because as it stands, to people who know anything about either field, his statement seems to be rather a ploy to get funding from retarded govenment officials who already hate violent games, than an actual attempt at doing real research.
