Floyd Mayweather is a flamboyant personality that does his part for the media. When you see Mayweather cruising around looking for a burger joint prior to his fight with Canelo for example- this is his way of making a statement for the public and a psychological game for Canelo that you have to remain starved and weak for another 2 days to make weight whilst I can relax, eat whatever I want and come fight night it wont make any difference, I'm still going to kick your ass!

What you have to realise is that behind the scenes of what you see on the cameras, Mayweather is a very dedicated fighter who trains very hard around the clock, not fooling around what you are shown on TV, and his team would have a dietician hired to cater to his requirements whether he is moving up or down to maximize his energy like every other top level boxer today. His dad and uncle would not be in charge of something like that. And I think his dietician is introduced in a Mayweather documentary. A pretty lady by no small coincidence lol. I don't think that diet consists of Kool-Aid and McDonalds very often!
