I think that Vince is the kind of guy that 'goes by feel'
Feel what - the layers of lard presently there? Look - there is a way to get rid of fat fast cleanly - its called stop eating and do a lot of work. Neither of which I think VG is mentally in that place for.
Secondly - VG is now what 40 something? Its not as easy now as say when he was in his late 20's early 30's. He can Keto whatever the f he wants, eat chittlens and pork rinds and lard to his hearts content, but if he wants to get in anything resembling decent shape - not a stage which to me seems he needs minimum 52-64 weeks - he needs to get real.
Its gonna suck - he needs boot camp workouts daily - diet restriction - stop FNG this southern BS cooking w biscuits gravy ocra chittlens grits or whatever the f they eat. He needs straight broccoli - steamed white chicken breats, fish, and a little rice - a little - nothing else. And gallons of water to drink. No grape juice, OE, Colt 45, none of that crap.
Lets see if it happens.
