Why Casey Ruff's Clients Lost 732 lbs — And 98% Was Fat
Description
In this episode of The Feldman Protocol, can elite athletes truly thrive on fat alone — with zero carbs? Dave sits down with Casey Ruff (personal trainer, nutrition coach, and host of Boundless Body Radio) to explore his journey from gym kid to keto rebel, high-intensity training principles, a rogue low-carb experiment inside a corporate fitness company that produced 732 lbs of fat loss, the LMHR study saga, carnivore adaptation and anxiety relief, and a surprising email from the American Heart Association.
