EXCELENTE A base de 28 reseñas Publicado en Adam LaamouzTrustindex verifica que la fuente original de la reseña sea Google. These two photos are taken 8 weeks apart. I started working with Byron 8 weeks before my fight. When I first went to him, I had a very clear problem: 10 weeks to lose 11 kilos. I sent him my photo and asked him straight up if it was even possible for me to make weight. Byron looked at it and immediately told me, yes — it’s possible. We jumped on a call where we discussed everything: what I like and don’t like eating, my habits, my training load, and the intensity I train at. Within a few days, he came back to me with a fully customised plan designed not just to lose weight, but to preserve and even build muscle. Honestly, at first, I didn’t believe it. Eight weeks felt like too little time to change that much and drop so much weight. But within the first few weeks, the results were undeniable. I started losing a significant amount of weight, yet I wasn’t getting smaller. Quite the opposite — I was clearly losing fat and gaining muscle at the same time. The diet itself was extremely sustainable. It included snacks, pasta, rice, cheese, and a lot of protein — and I mean a lot. I was never starving, always full, and even had things like orange juice included. We constantly adjusted the plan around my training schedule, and whenever I felt depleted, Byron adapted things immediately. What really stood out was the personal support. Byron checked in on me frequently and made sure I was okay both physically and mentally, and that my energy levels were always where they needed to be. During the final cut phase, Byron was with me every single day, right up until the weigh-in. On fight day, I felt fully replenished and noticeably bigger. I regained 5 kilos, felt incredible, and performed exactly how I needed to. I highly recommend Byron as a combat sports nutritionist. I’ll also be continuing to work with him to maintain a lower walking weight. More than that, I highly recommend him as a person as well as a professional. Thank you, Byron.Publicado en Leeon MontanaroTrustindex verifica que la fuente original de la reseña sea Google. Really happy I worked with him.

Working with Byron has been a game-changer for my weight goal. From the very beginning, he took the time to understand my goals, lifestyle, and training regimen, and built a customised nutrition plan also including an exercise program that was both effective and sustainable. Since I started the nutrition plan, I already noticed major improvements in my training performance, energy levels and body composition.
