“carbs build fat, never muscle”. That statement is not correct. "
A few points:
Vince never advocated steroid use. Carbs are of the most use when “on”.
Given that the average American eats a whole shitload more carbs than he needs to, Vince thought it prudent to try to swing the balance the other way a bit.
Given that he was maintaining the above in the 70’s and 80’s, when high-carb, low-fat diets were all the rage, again, he thought it prudent to try to swing the balance the other way a bit.
No one knew anything about post-workout nutrition at the time. All they knew was that you should eat “something” soon after you worked out. Actually, most people didn’t even know that (as they still don’t today, although this is changing). Vince was one of the few who was advocating getting something into your system within an hour after working out.
He knew this back in the 50s.
He got better results with P+F meals than Anything+C meals. Basically, it was the Anabolic Diet that he advocated (again, half a century ago), with a carb-up every four or five days, depending on the person.
Sound a little better to you now?
