Over dieting when you still have fat to lose? And I'm sure his body didn't "shut down"... I'm sure he was on steroids, thyroid, ephedrine etc... keeping the metabolism high. There is no starvation mode when you are "assisted".
OK Enough of me teasing Jack.....I was just having a little fun.
its total bullshit that your body cant shut down while "on"...but I dont think thats the case at all.
after not competing for a few years, when i warmed up at the golds classic last year before the npc nationals....i was on zero carbs for 4 days untill i started carbing up on thursday...
on wednesday night, i was ready....on saturday i looked like ASS...and was FLAT from CARBS, and could not get a pump at all.
i did the east coast a week later, and for 6 days i went zero carbs but added fats...at the east coast i was tight, hard, and ripped.
i think the same thing happed to jack
