Re:Theoretical question... saturated fat percentage vs exercise
saturated fats increase cholestrol in your blood which can ultimately lead to a heart attack/stroke and narrowing of the arteries etc.
Exercise reduces blood pressure and decrease cholestrol in your blood.
I would assume that depending on the proportion of each would depend on how much risk you have. For example, if you have 1000 calories of saturated fat a day, but you exercised to an amount that would negate the effects of consuming said saturated fat, then i cannot see why there would be able negative biological effects.
However in addition to this, generally foods with a lot of saturated fats in are processed (refined) and thus are generally made of simple carbs, which cause a fat increase with the exception to fruits, milks and yogurts. (Got to have everything to a moderation otherwise anything and everything will be bad for you)
