If you have been watching all access on Showtime or 24/7 on HBO, the documentary series leading up to Mayweathers bouts over the past few years you may have noticed Mayweathers diet. Floyd says he eats junk food every night including soft drinks and other high fat fast foods such as Mcdonalds. However it seems this has been totally scripted and is fake.
Mayweather recently told reporters at the post fight press conference of the Maidana rematch that Alex Ariza was brought into his camp to help him improve his diet. Floyd said that his improved diet improved his legs later in the fight.
