imo, i think that shyt a waste of money and something a fighter should take the time out to study on their own. as a fighter, i always want to know what it is im putting in my body. how hard is it really to read a book, or even ask a doctor to find out what nutrients your body needs? really?
im no genius at losing weight but as far as using common sense, you should know to stay away from junk food(candy, burgers, soda, etc). being a pro fighter, nutrition should be apart of your lifestyle. im not saying you have to be a super healthy motherfukkka, i believe in living life and eating bullshyt here and there on a occasion.
