The late Vince Gironda, aka "The Iron Guru," was one of bodybuilding's most-influential personalities and one of the greatest physique trainers of all-time.
Larry Scott, the first Mr. Olympia, trained at Vince's Gym. Mohamed Makkaway, one of the greatest IFBB pros of the '80s, also trained with Vince.
For 55 years Vince lived and breathed bodybuilding, establishing methods and principles that are still unsurpassed today.
When Vince had a student who wasn't making gains, he would put them on a diet of raw vegetables for 5 to 7 days… no protein or supplements whatsoever.
Vince claimed that excess waste products in the intestines from high animal protein intake, junk food and bad eating habits "gummed up the works" and would prevent gains.
So his students would eat NOTHING but raw vegetables and leafy green salads with a little vinegar for 5 to 7 days.
He would also have them take psyllium seed powder with water to help clean out the colon.
Once everything was cleaned out on the inside, his students would start eating their regular Vince Gironda diet again and would make much better gains.
I can't tell you from personal experience if this works or not… but I'm going to try it soon.
I would add just one very important recommendation because our food supply has changed a lot since the 50′s and 60′s…
Due to the prolific use of toxic agro-chemicals on our produce, I would highly recommend you use only certified ORGANIC vegetables during this "clean out" period.
In fact, I recommend you use organic vegetables at all times… if you're able to get them.
Give this a try for 5 to 7 days and let me know how it goes for you.
