Weight / Fat loss

For boxing I wouldn't bother with much attention to diets long term, just get the nutrition you need to recover and train well. I would do fuckloads of conditioning though and do an extreme cut close to fight dates including good old fashioned dehydration. It maybe worth practising "cutting" to learn how long it takes you.

DFP - no disrespect but wondered if you've ever done much boxing and what you're basing your advice one?
