If you’ve ever been told a pound of muscle burns 50 calories a day, that carbs make you fat, or that you must do fasted cardio to see results — this one’s for you.

In this episode, I sit down with exercise scientist James Krieger to unpack what’s real, what’s outdated, and what actually matters for lasting results.

We cover:

  • The real number of calories muscle burns (it’s not 50 per pound)
  • Why “slow metabolism” is mostly a movement problem, not a genetic curse
  • How much muscle you can realistically build per month
  • Why low-carb and fasting aren’t magic — they just help people eat less
  • What insulin really does (and why healthy people don’t need glucose monitors)
  • Why the “anabolic window” is mostly myth
  • The real reason fasted cardio doesn’t outperform fed cardio
  • How overcomplicating your health with gadgets and “cycle syncing” just adds noise

James and I also talk about how perfectionism and micromanaging every detail can actually make you miss what matters most — consistency, adherence, and real-life flexibility.

🎧 Hit play — and get ready to rethink everything you’ve been told about metabolism and fat loss.
