> I find it interesting why that doctor's reasoning is flawed I can't imagine a scenario where that cereal/grain recommendation in GP quote isn't sponsored or populistic at the time though. And while their method/reasoning wasn't flawed if they indeed had no research opposing their recommendation, that's kind of a straw man from the main issue of avoiding fat being legitimately bad. You need energy, and you get some from protein which you desperately need, but you can't get all your energy from protein, and that leaves you fats or carbs. Of those it's so much worse to avoid fat than carbs.
