Ben Greenfield: The Biohacker Who Eats Like a Caveman and Trains Like a Machine
If Bryan Johnson is the anti-aging, data-obsessed mad scientist of biohacking, then Ben Greenfield is the primal warrior who hunts down optimization like it’s his last meal.
The former bodybuilder, endurance athlete, and human guinea pig has built a reputation for pushing his body to the edge — then dragging it back stronger, leaner, and sharper than before.
Greenfield’s brand of biohacking isn’t about hiding from age in a multimillion-dollar tech bubble. It’s about building an unbreakable body and mind using a mix of ancestral wisdom and cutting-edge science.
The Greenfield Grind
Want to know what peak human performance looks like? It starts with treating your body like a high-performance engine. Greenfield’s daily protocol is a blend of hardcore training, primal nutrition, and borderline insane recovery tactics:
🔥 Workouts That Crush Souls – Rucking, kettlebells, cold plunges, altitude training. Greenfield doesn’t just lift weights — he makes his body battle the elements.
🥩 Meat, Organs, and Bone Broth – Forget the plant-based. Greenfield’s diet is a carnivore’s dream, packed with grass-fed beef, wild-caught salmon, raw dairy, and organ meats loaded with nutrients.
🧊 Ice Baths & Heat Shock Therapy – This guy lives in saunas and ice baths, pushing his nervous system to adapt like a modern-day Viking.
💉 Peptides, Nootropics, & Biohacks Galore – From testosterone-boosting peptides to light therapy and microdosing, Greenfield treats his body like a science experiment — except he’s the mad scientist AND the test subject.
What’s Real & What’s Hype?
🦾 Fact: Strength Training is the Ultimate Anti-Aging Hack
Muscle is longevity gold. Greenfield trains with resistance daily, keeping his testosterone high and his body lean. Lifting heavy keeps you young — science backs it up.
🥩 Fact: Eating Nose-to-Tail is a Nutritional Power Move
Organ meats like liver, heart, and bone marrow are nutrient-dense powerhouses loaded with bioavailable vitamins. Greenfield swears by them — and honestly, modern science agrees.
🧬 Fact: Biohacking Is Still an Experiment
Peptides, nootropics, and high-tech recovery tools might speed up results, but long-term safety is still in question. Greenfield bets big on these hacks — but you don’t need a lab full of gear to level up your body.
Should You Go Full Greenfield?
If you want to build a body that can go to war, Greenfield’s methods aren’t a bad blueprint. Train like a beast, eat real food, and expose yourself to stressors that make your body adapt.
