Brock Lesnar's diet: What does WWE's beast incarnate do to stay fit?

Brock Lesnar is one of the biggest WWE superstars

Brock Lesnar is more than just a dominant force in WWE. He’s a machine built on discipline, hard work, and a carefully curated diet. Known as “The Beast Incarnate,” Lesnar’s fitness approach is rooted in precision, favoring function over flair.

Behind his powerhouse persona lies a routine defined by clean eating, intense training, and a relentless commitment to recovery and performance. His nutrition plays just as big a role as the time he spends in the gym.

Brock Lesnar has a high-protein diet

Brock Lesnar’s meal plan is designed to maximize muscle, boost energy, and support recovery. It’s not fancy, but it’s brutally effective.

Breakfast

• 6 whole eggs
• Plain porridge
• 2 cups of raw eggs (blended and consumed)

Lunch

• 2 cups of brown rice
• Chicken breast (grilled or baked)
• Mixed vegetables (preferably homegrown)

Dinner

• 1 scoop of whey protein
• 1 banana
• 2 baked potatoes

He avoids processed foods and focuses on nutrient-dense whole meals. Lesnar has also shared his preference for homegrown vegetables, believing they pack better nutrition than store-bought options.

Hydration is key; he drinks over 5 litres of water a day to keep his system running optimally, especially given his physical demands.

The Beast Incarnate’s training regime is no less

Lesnar’s workout routine is split into multiple disciplines. He combines wrestling drills, striking, strength training, and cardio to maintain both mass and mobility.

Striking session

• 25 minutes, twice a week

Wrestling drills

• 10+ minutes, four times a week

Strength training split

• Chest & Triceps
• Back & Biceps
• Shoulders
• Legs

He trains with purpose, targeting specific muscle groups with compound lifts, and focusing on explosive power and endurance.

In 2022, Lesnar revealed that he had adopted a keto diet at times to keep his body fat low and energy levels stable. The high-fat, low-carb approach helped him stay lean without compromising his strength.

When paired with his training and clean meals, keto adds another layer of discipline to his already intense fitness lifestyle.

Brock Lesnar’s shocking return at SummerSlam 2025, dropping John Cena with an F5 after Cody Rhodes’ title win, proved that even after two years away, The Beast Incarnate hasn’t lost a step.

At 48, he remains one of the most imposing forces in WWE, thanks in large part to his relentless dedication to staying in elite shape.

Whether he’s stepping back into the ring or preparing for the next big fight, Brock’s fitness approach continues to fuel his dominance.
