It is illogical to Hollywood Keto think that your health and weight are going to be in balance if your nutrition consists mainly of twinkies, chips, and donuts. Sure you can burn it off by exercising, but most people whose diet consists of mainly junk food are probably not disciplined enough to stick to a workout routine. I do know a few people who, from the outside, look like they are in good shape, because they are not "fat, but who have high cholesterol.
Just because I feel sorry for crushing the hearts of so many twinkie lovers out there, I would say this. You can eat junk food, cookies, chips, ice cream, pizza, burgers.... All of those "soul satisfying foods", but it should be in moderation. Anything in excess is never good.
