i can only see it improving his athleticism. not that that's been a problem for him, but more athleticism is always better, and it wouldn't in this case come at the expense of anything. the excess fat is just that - excess. non-functional. he'd very likely be able to perform higher quality work in his camps at a lower weight which would transfer over to a more vigorous physical performance in the ring. even just considering the running/jogging work.. he'll set personal bests in those solely by losing weight, thereby increasing his cardio capacity, and in turn, with his newly acquired ability to recover better from his workouts, be able to do more in training (volume + intensity).
The problem with dieting is that he will also lose muscle along with the fat. We've seen it negatively effect Fury IMO.
Depends on how the diet is approached. It's best if the loss is incremental, not a blowout of negative calorie intake + extremely intensive exercise. I think the potential for loss of strength and muscle mass can be countered by moderate - high intensity weight training. I'm assuming Fury dropped the weight too fast. These instances are when truly professional nutritionists and conditioning coaches working in tandem really make a difference.
Well I wouldn't work with anyone who called them self a nutritionist full stop. If you're not good enough to become a certified dietician then who the hell are you to come in and advise a pro athlete on what to eat? I hate that all these charlatans can take people's money without being remotely qualified. Ed. This is aimed at 'nutritionists' not you BTW.
Just be here after the fight and remember what you said. Don't run, don't hide when those words come back to haunt you.
