Of any UFC lightweight who’s most likely to draw a ‘what weight are these guys? Welterweight?’it’s got to be Gleison Tibau. There are fighters that are ‘big’ for the division, and then there are competitors who are ‘massive’ for thei weight class. Mr. Tibau is definitely the latter.

While Tibau is a BJJ black belt and extremely talented fighter, there’s no question that the strength and size advantage he usually has over opponents is a key reason why he’s been with the UFC going on seven years. Most recently, Tibau worked his way to a split decision win over former WEC champ Jamie Varner at UFC 164 to extend his overall record to 28-9. So how much did the lightweight weigh that night? According to a report from MMA Fighting.com, 181 pounds. That’s right. The 30 year-old fighter put on approximately 26 pounds between the weigh-ins and fight night. That’s ridiculous.

The story also includes several comments from Tibau’s trainers at American Top Team, who evidently have helped the fighter master the weight cutting process. Here is some of what one of the vet’s trainers, Stephane Dias, had to say about the process.

“During the fight week, he works on the technical part with striking coach Luciano ‘Macarrao’ and jiu-jitsu coach Marcos da Matta, but also maintenance the aerobic workouts to help weight loss together with a dietary restriction of solid foods and an increase in fluid intake ranging from six to eight liters per day (distilled water) — or water with zero percent sodium — for a period of two days after gradually reducing the water,” Dias said. “This causes the body to eliminate more water and not retain anything in the moments prior to weighing.”

“After this brief recovery, he eats light food which is quickly absorbed, like bananas, grapes, fruit salad, as well as Vitamin Water or Gatorade,” Dias says. “The weigh-in usually occurs late into the night and the athlete is already semi-recovered. We continue with the intake of low-fat foods that are rich in carbohydrates every two hours, and also make shakes with added glutamine, dextrose, maltodextrin and vitamins to obtain a super compensation carbohydrate and assist in performance the athlete. We also add calcium pills, potassium and magnesium due to dehydration to avoid cramps on fight time.”

Another of Tibau’s trainers, Everton Bittar, revealed that the fighter has even got up to 186 for a fight, but that they noticed it “negatively affected his movement” in the cage. Yup, that’s a pretty massive lightweight.
