Brock Lesnar is an American professional wrestler, WWE performer, and UFC mixed martial artist famous for his fighting skills, aggression, and monster strength. For nearly two decades, Brock Lesnar’s name was synonymous with brute power. He was “The Beast Incarnate”-a freak athlete who dominated the NCAA mats, conquered UFC cages, and ruled WWE rings. By his late 40s, the same body that made him famous was wearing him down. Chronic inflammation, fatigue, and weight fluctuations began to take their toll. “I built myself into a monster,” he once told a friend. The hard-hitting heavyweight, Brock Lesnar, works hard to stay in shape.
Brock Lesnar’s weight loss wasn’t about vanity or performance. It was about survival-physically, mentally, and spiritually. He had to look in the mirror and ask himself what he really wanted. With the support of his family and a newfound commitment to his health, Lesnar embarked on a weight loss journey that would not only reshape his body but also his outlook on life. As Lesnar put it best, “You don’t stop being The Beast when you change.
The Turning Point: A Need for Change
At 6’3” and over 285 pounds, Brock Lesnar was the definition of a powerhouse. His size, speed, and explosiveness made him a genetic marvel. Years of heavy lifting, protein-bulking diets, and relentless physical punishment left his body under siege. “I felt trapped inside my own strength,” he reflected privately. Lesnar’s intense lifestyle-high-calorie diets to maintain muscle mass, extreme weight training sessions, and adrenaline-fueled performances-started to catch up with him. By 2022, he began to notice something different: his stamina was fading. Simple movements felt heavier. According to sports nutritionists, this decline is common among aging athletes. “As men enter their 40s, testosterone levels and muscle recovery drop,” explains fitness expert Mark Voss.
After a family fishing trip on his farm in Saskatchewan, Lesnar’s daughter challenged him to a friendly sprint back to the house. He accepted-of course he did. “She laughed, but I didn’t,” he later said. “That moment hit me. That night, he decided to make a change. Not for the cameras. Not for a comeback. “I don’t want to be bigger anymore.
Nutritional Transformation: Simplifying Food Sources
Brock’s first change was in the kitchen. Gone were the processed foods and excessive supplements. Nutritionists often note that simplifying food sources reduces inflammation and promotes metabolic efficiency. “For someone like Brock, who’s experienced gut issues, whole-food nutrition is a game-changer,” says sports dietitian Dr. He shed over 30 pounds in the first three months, most of it from water retention and body fat. But the biggest change came from how he felt. “I finally had energy again,” he said. “I didn’t feel like a machine.

Brock Lesnar’s meal plan is designed to maximize muscle, boost energy, and support recovery. He avoids processed foods and focuses on nutrient-dense whole meals. Lesnar follows a high-protein, high-carb plan with eggs, chicken, rice, vegetables, whey protein, bananas, and baked potatoes. In 2022, Lesnar revealed that he had adopted a keto diet at times to keep his body fat low and energy levels stable. Having spent his early years in South Dakota, Lesnar always prefers eating game meat over store-bought meat. Game meat is considered one of the healthiest sources of meat as it is low in fat and cholesterol.
Lesnar added that he consumes around 300 grams of protein every day to maintain his monster physique. In other words, he eats close to one gram of protein per pound of body weight every day, which is more than the recommended 0.8-1 gram of protein per kilogram of body weight per day. Although the WWE superstar follows a high-calorie diet, he does not use it as an excuse to binge on unhealthy foods.
Lesnar's battle with diverticulitis forced him to overhaul his diet. He lost 42 pounds during the fight. He's put some of that weight back on but doesn't plan on going back to the days of walking around at close to 300 pounds between fights. "I've gotten rid of a lot of bad things in my diet. I'm eating a lot cleaner," said Lesnar, during a UFC 116 teleconference. He mentioned he was eating some chicken, broccoli and boiled potatoes. "The four food groups is kind of a hoax." "I've had to change my diet, and you have to make food part of your life," said Lesnar. "I feel better. I recover faster. If I wasn't seeing the results I'm seeing, it would be very hard to do." Lesnar said he was at 265 this week and won't need to cut weight next week.
Evolving Workout Routine: Quality over Quantity
Brock’s workouts used to be brutal-two-hour powerlifting sessions, heavy deadlifts, and Olympic lifts designed to build mass and explosiveness. He trained less often but more efficiently-45 to 60 minutes, five days a week. “I used to lift like I was angry at the world,” he admitted. Fitness coaches often stress that as athletes age, recovery becomes as important as training. Lesnar follows a high-volume training regimen and performs at least 21 sets in each workout. Lesnar might spend up to 2-3 hours in the gym on a typical day. However, he breaks down his MMA and weight training routines into two different sessions. Lesnar works out six days a week, including his MMA, gym, and circuit training routines. The former UFC Heavyweight champ follows a four-day strength training regimen to build muscle mass and strength. Lesnar performs one set of each round in his circuit training routine. You are allowed a thirty-second rest in between exercises.
However, running with a tree trunk on your back alone cannot help you exchange blows with the top fighters in the world in a UFC cage or beat the Undertaker at Wrestlemania. Being in the WWE is an exercise in endurance. Many wrestlers perform some 200 days a year. Lesnar has learned the importance of taking recovery time and prioritizes it. Besides, he uses a personalized diet and supplementation program to help with his recovery. Lesnar has learned most of his dieting and training principles the hard way.

Lesnar is quick on his feet for a big guy with massive muscles. This is because while he dedicates his time to his training, doing a lot of lifting, he also does a lot of cardio. Brock Lesnar often runs down the hill with a 180 lbs weighted log, which helps him build strength. Lesnar’s progress and achievements are awe-inspiring because, as a young athlete, he didn’t have a gym at his disposal. So, he used any equipment he could find on the farm he lived to train. Brock Lesnar mostly does a bro split, focusing on different body parts during the week. For instance, he may work his lower body on one day and his chest and shoulders the next. He also prioritizes rest, which helps his body recuperate after intensive workouts. Before his daily resistance training, Brock Lesnar starts his day with total body movement as warm-ups to get the blood pumping into parts of his body. Brock Lesnar strikes for 25 minutes at least twice weekly. He also wrestles for 10 minutes at least four times weekly before moving to his resistance exercises.
Mental Fortitude and Lifestyle Adjustments
Brock Lesnar has always been known as a private man. He began prioritizing peace. Life on his farm became his sanctuary. Mornings started with silence, not screens. “I used to think rest was weakness,” he said. He also adopted a minimalist lifestyle, focusing on family, nature, and faith. “I’ll always be The Beast in the ring,” he smiled. Despite his progress, the journey wasn’t seamless. There were days when the old cravings returned. Social media speculation added another layer of pressure. Fans noticed his leaner frame, with comments ranging from admiration to concern. But Brock stayed focused. “The world will always have opinions,” he said. Experts emphasize that identity shifts are the hardest part of long-term health changes. “When someone’s career revolves around physical dominance, letting go of that identity takes courage,” says performance psychologist Dr.
According to The Beast Incarnate, the game is mental as much as it is physical. Lesnar has also created a hobby of hunting and butchering meat. He even invented his brand of seasoning for his meat.
The Results: A Sustainable Transformation
By early 2025, Brock Lesnar had lost nearly 40 pounds and reduced his body fat by over 6%, dropping from around 285 to 245 pounds. But more than his appearance, what stunned fans was his vitality. His WWE colleagues noticed, too. “He walks differently now,” one insider said. “I’m still strong,” Brock said. “But now, my strength feels sustainable. I can pick up my kids, ride horses, and wake up without pain.
Lesnar said he was at 265 this week and won't need to cut weight next week. He's usually the much bigger man in his fights but not this time around. Shane Carwin is also naturally up around 300 and this week was 275. But Carwin said he won't be fooled into thinking Lesnar is an easier mark now. "With cleaning up his diet, I'm sure he's just as strong and probably more explosive," Carwin also said on the conference call.

Diverticulitis and its Impact on Lesnar’s Career
Lesnar's battle with diverticulitis forced him to overhaul his diet. He lost 42 pounds during the fight. He's put some of that weight back on but doesn't plan on going back to the days of walking around at close to 300 pounds between fights.
Brock Lesnar has returned to the WWE, and his return is one of the most talked about returns in years. His return, however, was based on the fact that he retired from UFC, and his battle with diverticulitis was the likely cause of his retirement. Brock was one of the greats in UFC until it was discovered that he had diverticulitis, an illness that could have taken his life, had he waited much longer for treatment. In November of 2009, Brock was diagnosed with mononucleosis, and later in the month it was discovered he had a serious case of diverticulitis. The condition was so serious, that surgery was required. Surgery is not the first treatment for this illness, and normally only done when severe risk of infection or other health risks to the patient require a surgical intervention. Diverticulitis is a disease of the digestive tract, normally in the large intestine. On the colon of the patient, tiny pouches form. These pouches are called diverticula. When these pouches become inflamed, diverticulitis is diagnosed. Symptoms of the disease include; fever, lower left abdominal pain, diarrhea and nausea. A blood test can also be done, and if a high white blood cell count is present, along with the above symptoms, the doctor can be assured of the diagnosis of diverticulitis.
Doctors are still unsure as to what exactly causes diverticulitis. The current theory is that increased pressure in the large intestine can lead to this condition. The thought process goes on to say that a lack of fiber in the diet leads to increased pressure. Fiber is necessary for people because it aids the digestive tract. Fiber helps regulate bowel movements. When bowel movements become harder to pass, fecal matter gets backed up in the intestine. The backup of fecal matter increases the pressure in the intestine and in the colon. This is an interesting theory, especially when you consider it in the case of Brock Lesnar. Brock was a mixed martial artist for the UFC. This type of job puts the body under a great deal of stress, and forces the athletes to train, and fight while hurt. It is not uncommon for these athletes to have prescription pain-killers to help them work through the pain. One of the main side effects of these types of pain-killers is constipation. Constipation is the inability to have regular bowel movements. It is not uncommon for someone to go a week without a bowel movement while on these medications. This alone could easily account for the increased pressure in the colon and intestine, that doctors believe cause diverticulitis.
On November 16, 2009, Lesnar underwent surgery for his condition. The surgeon had said that fecal matter was leaking into the abdominal cavity of Lesnar. This leakage was causing abscesses to develop, and it also forced Lesnar's immune system to work overtime. The anti-bodies of Lesnar's immune system were attacking the fecal matter as if it were a virus. The anti-bodies were not able to remove the fecal matter, and continued to attack it. Lesnar had become very susceptible to other illnesses and infection because his immune system was focused exclusively on his abdominal cavity. Surgeons went in, and closed up the perforations in his intestine that were leaking the fecal matter. This would not be the last surgery Lesnar would need for this condition. In May of 2011, diverticulitis struck Lesnar again. Surgery was done once more, and Lesnar had a foot of his colon removed. Brock Lesnar is incredibly lucky to be alive. Diverticulitis, left untreated can lead to serious problems. Surgeons have said that the damage Lesnar had from the illness showed that he went undiagnosed with it for a year, and he had many fights in the octagon while he was undiagnosed with diverticulitis. At any time, a punch to his abdomen could have led to a rupture of one of the diverticula. The toxins released from a rupture like this could lead to a condition known as peritonitis. Peritonitis is when the tissue covering the organs of the abdomen become inflamed. Left untreated, peritonitis is almost always fatal.
Lesnar retired from UFC after a match he had in December 2011. During this match, his opponent targeted the mid section of Lesnar. Lesnar may have realized that he dodged the Angel of Death once, and that he needed to step away from the octagon. His opponents would always target his abdomen, and Lesnar would likely always have fear in the back of his mind that the diverticulitis could come back. No man can compete in the UFC if they have any doubt about their own health. Lesnar made the right decision. It is always important to choose health over a career. Now, Lesnar has come back to the industry that made him a star. Lesnar is back with the WWE. The environment of pro wrestling is still hard on the body, but it will be much safer for Lesnar in regards to his medical history. Lesnar will be able to compete knowing that he will not be subjected to repeated blows to the stomach. One thing that all athletes need to take away from the story of Brock Lesnar is to never ignore the symptoms your body tells you.
