Kell Brook is in the final stages of his most demanding weight cut to date. Sky Sports investigated keto diets, burning calories and cheat meals…
Nutrition expert Greg Marriott, the mastermind behind Brook’s weight cut to defend his IBF belt against Errol Spence Jr live on Sky Sports Box Office next weekend, exclusively explained the secrets of how to beat the scales.
How did the camp start?
Kell came out to Fuerteventura before the 10-week camp to get into a routine. He does two weeks without me so his weight doesn’t look so bad! He weighed 12st 5lbs. His body is just so dense.
After having 10 months out, we always knew he could get back to welterweight – but how long would it take, and how hard would it be?

Stone | 10st 7lbs | 11st | 11st 4lbs |
What was Brook’s diet like?
It’s very personal working with an athlete – you can’t just get a uni degree and give them a textbook diet. You need to make sure he’s feeling good, mentally and physically.
First, we put him on a strictly-controlled keto diet for a couple of weeks which burns fat. Then, at Sheffield Hallam University, we test his blood to see how many carbs he’s using. Then he goes on a low-carbohydrate high-protein diet.
