I take your point about diet not really affecting our ability to exercise enough for significant health benefits.
My initial point was that the effect sizes, even for things like red meat, are small overall compared to that of exercise, even if we accept the validity of observational studies as a given. Also, remember that any diet study in an industrialized society is going to be looking at diet against a background of energy overload and sedentary lifestyle, both of which are likely confounders.
