Johnny Walker discussed his plans to transition to the heavyweight division. He revealed that he has trained and sparred with Francis Ngannou, and even with a 20kg weight difference while on a diet, he was able to work comfortably with the former heavyweight champion. Walker explained that he would feel much better at heavyweight because his current diet leaves him unable to train properly, experiencing dizziness and low energy due to insufficient carbohydrates. He believes the move would benefit his performance and overall health. The post includes a poll asking whether he should try the move or if there are concerns about the transition.
Brazilian light heavyweight Johnny Walker has publicly stated his intention to move up to the heavyweight division, citing serious physical difficulties making weight at 205 pounds and encouraging sparring sessions with former heavyweight champion Francis Ngannou.

Walker, who stands six-foot-six with an 82-inch reach and carries a record of 22-10, is currently ranked 11th in the light heavyweight division. The 34-year-old SBG Ireland product explained that his current diet leaves him dizzy and low on energy due to insufficient carbohydrate intake, making it difficult to train properly. He described feeling noticeably more comfortable when working at a heavier weight, noting that even with a 20-kilogram gap between himself and Ngannou while dieting, he was able to spar effectively with the former champion. Walker lands 4.06 significant strikes per minute at a 55 percent accuracy rate, numbers that suggest his offensive output could carry well into a bigger division.
Ngannou, a Cameroonian heavyweight standing six-foot-four with an 83-inch reach, holds an 18-3 record and ranks 12th in the pound-for-pound listings at age 38. His willingness to share the mat with Walker provides a credible measuring stick for the Brazilian's transition ambitions.

Why it matters
- Walker's elite size for light heavyweight — six-foot-six, 208 cm reach — translates into a natural physical fit at heavyweight.
- A successful move could shake up a heavyweight division that has seen renewed flux since Ngannou's departure from the UFC.
- Walker's ranking at light heavyweight would not transfer automatically, meaning he would enter heavyweight needing to rebuild his position from scratch.
- Health-driven division changes tend to produce improved performances, which could make Walker a more dangerous version of himself against bigger opponents.
