Greenfield resolves the meat debate by rejecting the idea of one perfect diet and instead balancing the biochemistry. Muscle meat is rich in methionine, a pro-growth amino acid that, unbalanced, is linked to cancer and heart-disease risk, so longevity populations eat nose-to-tail (marrow, broth, liver, organs) to supply balancing glycine and nutrients. He layers in maximum dietary diversity to build a microbiome that can safely handle plant defense compounds like oxalates and lectins in trace, hormetic amounts. The verdict on any meat comes down to its source, what it's eaten with, and the quantity, refined by personal testing.
Origin
Drawing on the 1960s book 'Biochemical Individuality' and his study of longevity hotspots beyond the plant-leaning blue zones, Greenfield concluded that meat-eating centenarian populations thrive because they eat the whole animal with high dietary diversity, a pattern he now cooks into his own tri-tip recipe.
Core principles
- 01There is no single perfect diet for all humans (biochemical individuality).
- 02Muscle meat is high in methionine, which drives pro-growth pathways that can shorten lifespan if unbalanced.
- 03Eating the whole animal (bone broth, marrow, liver, organs) supplies glycine and nutrients that balance methionine.
- 04Dietary diversity builds a robust microbiome that can handle plant defense compounds.
- 05The health effect of meat depends on its source, what it's eaten with, and the amount.
How to run it
- 1
Interrogate the meat, not just 'meat'
Before judging red meat as healthy or not, ask where it's sourced, what it's eaten with, and how much you're eating.
Pro tip In the West, red meat is often eaten with fries, soda, seed oils and processed sides that skew the health data against the meat itself.

Eat nose-to-tail to balance methionine
Include bone broth, bone marrow, liver, kidney and heart alongside muscle meat so methionine is balanced by glycine and organ nutrients.
Pro tip Soak tough organ meats in a dairy medium like kefir or buttermilk for ~24 hours to draw out gamey flavor and pre-digest them; organ capsules are a shortcut.
Watch out Excess muscle-meat methionine without glycine keeps a mammal in pro-growth mode, raising cancer and heart-disease risk.

Cook to counter charring
Add herbs and spices (turmeric, oregano, garlic) that help combat the carcinogenic effects of heating or charring meat.
Pro tip Greenfield rubs his tri-tip with salt, pepper, turmeric, oregano and garlic and cooks it under a layer of beef tallow with marrow bones as sauce.

Maximize dietary diversity
Surround meat with a wide array of herbs, spices, fermented foods, fish, eggs, vegetables, fruits, seeds and nuts to build a diverse microbiome.
Pro tip A diverse microbiome lets your gut bacteria handle plant defense compounds (oxalates, lectins, phytates) as beneficial hormetic stressors rather than irritants.
Watch out A myopic, low-diversity diet leaves your gut unable to handle plant defense mechanisms.

Personalize with data
Use food-allergy, genetic, blood, stool and urine testing to distinguish a true allergy from a diversity-solvable sensitivity and tailor the diet.
In the wild
For dinner Greenfield rubs a tri-tip with salt, pepper, turmeric, oregano and garlic, cooks it under a layering of beef tallow, and tops it with bone marrow bones as a sauce, deliberately combining tallow, marrow and muscle meat with anti-carcinogenic spices.
→ A meal that balances muscle-meat methionine with organ-derived nutrients and counters the downsides of charred meat.
Common mistakes
Eating muscle meat in isolation
Consuming only muscle meat delivers excess methionine without balancing glycine, keeping the body in a lifespan-shortening pro-growth state.
Assuming one diet fits everyone
Biochemical individuality means genetics, organ sizes and digestive capacity vary widely, so no single diet is optimal for all humans.
Is it for you?
Best for
Omnivores who want the benefits of meat without the growth-signaling and microbiome downsides of the standard Western pattern.
Not ideal for
People with true diagnosed food allergies to specific foods, who need a personalized rather than general approach.

“they are having bone broth, bone marrow, uh liver, kidney, heart, and many parts of the animal that allow them to not just be consuming…”
