The diet-heart hypothesis was built on cherry-picked data from 1960. The science has moved on. The guidelines haven't.

Niklas Gustafson — celiac from birth, 13-time Ironman finisher, co-founder of Natruly, and host of Hungry for Change — on ancestral nutrition as a lived practice, why real food is the most radical act left, the plant milk scam, oxalates nobody talks about, and what four years without alcohol actually changed.

The CO₂ tolerance system for BJJ over 40 — why you gas out mid-round, what's actually happening in your body under pressure, and the exact protocol to fix it.

Sunlight isn't a cancer risk — it's the master signal for every hormonal, circadian, and metabolic process in your body. Avoiding it is the disease.

Not despite high-frequency training — because of it. Here's the full breakdown of how intermittent fasting and daily grappling coexist and reinforce each other.

Not all bread is bread. The long fermentation that makes real sourdough destroys anti-nutrients, colonises your gut with beneficial bacteria, and lowers the glycaemic response. Here's the science.

Not a compromise. Not a modified, gentle version of grappling. The full system for staying on the mats, staying dangerous, and staying hard to kill.

Nature's original supplements. More bioavailable nutrition per gram than anything else on earth — and we threw them away.

Sodium Bicarbonate is not just for baking. It's a proven acid buffer, a gut alkalizer, and — according to University of Arizona research — a potential anti-cancer agent. I use Bob's Red Mill daily.

The IARC classification, the cherry-picked data, and why the epidemiology on red meat has been systematically misrepresented to the public.

No supplement, cold protocol, or sauna session competes with what happens when you sleep correctly — and most midlife athletes are destroying their recovery every single night.

Cold immersion is one of the most studied recovery tools available — and for midlife grapplers training twice a day, the hormonal and performance case is hard to argue with.

Quantity doesn't fix quality. Here's the science on why plant protein fails midlife combat athletes — and what to eat instead.

Staph doesn't need an invitation — it's already living on most of us. The question is why your body lets it in. The answer is more complex, and more within your control, than the mats-gave-me-staph narrative allows.

Tai chi rebrands. Lymphatic tapping goes viral. Mobility flows get sold as transformations. None of it is wrong — but the packaging changes every six months and the principles never do. Here is what the science actually says, and why the routine we do every morning works.

Polyester underwear is quietly destroying testosterone, fertility, and hormonal health in men — and the rash guard you train in every day is making it worse. Here is what the research actually says, and what you need to do about it.

Free electrons, cortisol reset, and the recovery tool your ancestors used every single day — that you stopped using the moment you put on shoes.

A full-day, science-backed framework for athletes training hard after 40 — every element, every mechanism, and exactly why it works.

You're not panicking because you're unfit. You're panicking because your CO2 tolerance is low. Here's what that means, why it matters, and how to fix it.
