The bottom line is this:
There are many ways to prepare for a show...the one constant I've seen in my 28 years of training and competing...is high protein. You need X-amount of calories just to sustain the amount of muscl mass you have. As one gets bigger and puts on more mass over time...their protein rquirements also get higher. In order to get lean while retaining muscle, the only way to get those calories....is from protein.
What Adonis is preaching has already been tried...many times. This isnt innovative or even original. Dr. Mario DePasquale (and probably some before him) brought this "revolutionary" method to the WBF back in the 90's....with dismal results.
I am personal friends with a few of the guys that were on the WBF, and had to follow this diet made up of high fat foods, high sugar foods, etc....a caloie is a calorie. The physiques displayed were among some of the worst I've ever seen on a pro stage...these guys looked like my balls (with all due respect to my balls!)
The answer to this great debate is simple....IT'S IN THE MIDDLE.
LIKE ALL THINGS IN LIFE...THE ANSWER LIES RIGHT WHERE PEOPLE FAIL TO LOOK...IN THE MIDDLE.
Gez...lets see..should I take 500g. of protein or 100g.??
Should I do 30 sets per bodypart, or 4?
Should I cut my water out 4 days out or 2 hours before the show?
Should I train heavy all the time, or mix in some rep work?
etc.
etc.
EXTREMES are the worst thing a competitive BB can do...every action will produce an equal and greator re-action...usually not for the better.
