In 1983 a Stanford-trained MD named Stephen Phinney published a paper in the journal Metabolism that should have ended thirty years of sports nutrition orthodoxy in a single afternoon.
The conventional wisdom in 1983 was simple. Carbohydrates were the fuel of endurance athletes. Without them, performance would collapse. Every coach, every nutritionist, every sports drink company agreed.
Phinney decided to test the assumption.
He recruited five well-trained cyclists and locked them in a metabolic ward. Week one, they ate a normal high-carbohydrate diet. Then for the next four weeks they ate less than twenty grams of carbohydrate a day. Eighty-five percent of their calories came from fat. Same total energy as before. Every macro counted, every meal supervised.
He took muscle biopsies. Muscle glycogen dropped by fifty percent.
Then he sent them to ride to exhaustion.
Their average endurance time was maintained.
The body had switched fuel sources. With glucose unavailable, it had ramped up fat oxidation in the muscles. The cyclists were running on body fat instead of muscle glycogen, and they could ride just as long.
Phinney had proven, in 1983, that elite endurance performance was possible on essentially zero carbohydrate. He published the data in a peer-reviewed journal. He submitted it for the world to read.
It was buried.
The sports nutrition industry had nothing to sell to athletes who could run on their own body fat. The gel companies. The drink companies. The pasta-loading rituals. Phinney's paper was an industry-killer, so the industry ignored it.
Thirty-three years later Volek's FASTER study ran the same experiment in ultra-runners and found the same result. The athletes burned fat at twice the rate science had thought possible.
Phinney went on to co-found Virta Health and reverse type-two diabetes through nutritional ketosis.
Your body has been burning fat the whole time.
Phinney proved it in 1983. The sports drink companies still pretend he did not.

People with Type 1 diabetes deserve access to every serious tool that may help improve blood sugar management, outcomes, and quality of life.
That includes learning from experts and patients exploring therapeutic carbohydrate reduction and low-carb approaches for Type 1 diabetes.
LowCarbUSA created a free YouTube playlist featuring presentations from the Type 1 Diabetes workshop at the 2023 Boca Raton Symposium for Metabolic Health.

@dailychartbook@Redfin Two possible contributing factors:
1) owners would lose their very low interest mortgages if they move.
2) Capital Gains. Yes, there is an exemption but if you’re downsizing then you still have to pay on the difference (the boot).
@BenBikmanPhD But now that all of the statins are off-patent, why are statins still pushed? There is no money to be made, except for the generic houses. Manufacturers of generic medications don’t fund academic research. There’s no money in it.
@agingroy@RapaNews@ColumbiaOBGYN@NatureAging That’s just the ovaries. What is the effect on the rest of the body. We cannot yet quantify with any precision but this effect on the ovaries gives us a strong clue.
