I recommended low-carb and intermittent fasting for nearly 20 years.

Then my labs started telling a different story.

In this episode, I break down why I stopped fasting, increased carbohydrates, lowered fat intake, and how that shift improved my fasting glucose, thyroid markers, LDL, sleep, and recovery.

This isn't anti-keto/carnivore. It's anti-dogma.

If you care about metabolic health, ATP production, thyroid function, or insulin sensitivity, this conversation will challenge what you think you know.
