James Ko | Nutrition & Performance Expert • Fat & BMI Scientist • Sports Physical Therapist • Over-50 Dad on a Mission

James Ko is a research-driven health professional with a heart for people and a bone to pick with outdated advice.

As a fat and BMI scientist, nutrition strategist, and licensed physical therapist with over 20 years of clinical experience, Ko has helped thousands—from CEOs to soccer moms—shed chronic inflammation, ditch stubborn weight, and rebuild strong, pain-free bodies.

But what sets him apart? He’s not just about hacks or hustle—he’s about healing the root cause.

When he saw 91% of adults (and 69% of kids) struggling due to metabolic dysfunction, he asked the hard questions:
“Why are we still telling people to cut calories and do more cardio—when that backfires for most?”

His answer: the 21-Day Metabolic Reset—a breakthrough protocol that retrains your body’s systems to burn fat efficiently, heal inflammation, and restore energy… fast.

Ko’s mission is simple:
To help you feel amazing again, and make it stick for life.
Because short-term wins mean nothing if you can’t turn them into a lifestyle.
