Why do some people eat more and stay lean while others diet nonstop and still struggle? Is your metabolism actually slow, or have you trained it to fight you?

I dive into the real science of metabolism, body recomp, and why most weight loss strategies fail long-term. The focus shifts away from eating less and toward building a body that can lose fat, build muscle, and handle more food without constant plateaus. I explain why chronic dieting backfires, how strength training reshapes metabolic behavior, and why metabolism is adaptive, not fixed.

I cover the four components of metabolism, why NEAT quietly drives fat loss, and why muscle is the biggest long-term lever for fat loss, muscle building, and strength training over 40. You’ll also hear about a zero-time habit that can add up to 9,000 calories of monthly burn without changing your schedule.

If you want evidence-based nutrition that actually works, this is where it starts.
