Eat well.
Feel the difference.

Meat, fruit, dairy, eggs. Cut the seed oils and ultra-processed food. Feel better, sleep better, have more energy. PMAB is a free, practical guide to eating in a way that actually works.

Why this exists

We started PMAB because we were tired of wading through three-hour podcasts, Reddit rabbit holes, and half-baked blog posts just to answer a simple question: what should I actually eat?

There's a lot of good information out there about metabolic health, animal-based eating, and the ideas of people like Ray Peat and Paul Saladino. It's just scattered everywhere. We wanted one place to bring it together — organized, honest, and easy to browse whether you're brand new or already deep in it.

We're not claiming these ideas as our own. The thinking belongs to the researchers, physicians, and communities who've been doing this work for years. We just want to make it more accessible — and if it helps some people feel better, great. If it doesn't land for you but unlocks something else that does, that's great too.

This isn't a finished project. It's a living thing — we're learning as we go, fixing what's wrong, adding what's missing. Some of what's here will probably turn out to be incomplete or off. That's fine. We'd rather put something real out there and improve it than wait until it's perfect.

What it is

Simple food. Real results.

Your body runs on energy — give it the right fuel
Chronic tiredness, poor sleep, sluggish digestion — research links these to how well your cells produce energy. Saturated fat from animal foods is a stable, clean fuel. Ripe fruit provides sugar in a form your liver actually uses. Together they support your thyroid, which regulates everything else.
·
Thyroid function drives metabolism, warmth, and mood
·
Fruit sugar (glucose + fructose) fuels liver and thyroid conversion
·
Saturated fat from beef and dairy is stable and hormone-supporting
Cut the stuff that works against you
Seed oils — canola, soybean, sunflower — are high in linoleic acid, a polyunsaturated fat that accumulates in your cells and disrupts how they produce energy. Studies show it suppresses thyroid function and increases inflammation over time. Swap them out, cook with butter or tallow, and most of the rest takes care of itself.
·
Linoleic acid from seed oils builds up in tissue over years
·
Saturated fats are chemically stable and don't oxidize in your cells
·
Whole food cooked in butter beats anything processed
The nutrients your body needs are in animal food
Beef, eggs, dairy, and shellfish deliver vitamins and minerals in forms your body absorbs directly — no conversion required. Iron from red meat absorbs at 25–35%. From plants, 2–5%. Vitamin A from liver is preformed retinol. From vegetables, it's beta-carotene that many people can't convert efficiently. The difference is real.
·
Heme iron from beef absorbs 10× better than plant iron
·
Liver provides real vitamin A — not the kind you have to convert
·
B12 only exists in animal food — no plant source provides it
The idea

Backed by two independent frameworks.

Ray Peat spent his career as a biologist studying how food affects energy production in the body. Paul Saladino is a physician who researched what humans evolved to eat. They had different methods — one was studying cells, the other studying evolutionary patterns — and they arrived at the same foods.

PMAB is the overlap. Meat, fruit, dairy, eggs. Skip the seed oils. Eat real food. It's not complicated, and the science behind it is solid.

"I think people shouldn't eat things that damage them, and should eat things that taste good and that provide the essential nutrients, while making them feel good and function well — is that a diet?"

— Ray Peat
