The thing you have to take into account is that these guys are already huge! Toney Freeman uses Palumbo diet and gets shredded no doubt, but he is already huge, he built that physique from years of eating massive amounts of carbs. I'm sure the same thing goes for Centaponi, he gets ripped when using Palumbo's diet, but I pretty sure to put all that mass on his frame he ate a ton of carbs for years, then used Palumbo's diet to refine and tighten up..right now he's trying to put mass on to compete in the pros and I'm sure he includes ton of carbs in his meals daily, but when he starts his contest prep I'm sure he'll go fat/protein.
