Tomorrow at midnight PST, enrollment for the FDC closes. So let me be very clear about what you're getting when you enroll in the Flex Diet Cert. Not hype. Not promises. Just the actual deliverables. → 8 Modules, 40 Action Steps Each of the 8 metabolic flexibility interventions gets its own complete module covering: The ongoing physiology of metabolic flexibility (why it works) A deep research dive on each intervention condensed into 1 hour using language you can understand with complete...

I could have built the Flex Diet Cert in a vacuum. Just me, my research, my experience, tons of coffee, and my opinions packaged into 8 interventions... ...But here's the problem with that approach: No matter how much I know about metabolic flexibility, I'm not the world's leading expert on protein metabolism. I'm not the top researcher on sleep and circadian biology. I'm not the guy who literally discovered the molecular mechanisms of muscle growth. So I didn't pretend to be. Instead, I...

Most people know what works. Protein helps.Calories matter.Sleep matters.Training matters. That’s not the bottleneck. The bottleneck is knowing when to stop doing the thing that used to work. Every intervention has a lifespan. Protein increases satiety, until intake drops too far.Low-carbZ improve glycemic control, until training quality degrades.Fasting improves fuel partitioning, until recovery collapses. The real coaching skill isn’t knowing what lever exists. It’s knowing when to let go...

There’s a moment most people never reach. It’s the moment where you stop asking“What should I do?” …and start asking“Why am I still guessing?” Adam hit that moment in late December. No cleanse.No public declaration.No desperate attempt to out-suffer biology. He just decided it was time for a drastic change, so we set out on a gameplan based on the Flex Diet Cert to get him significantly leaner and stronger in record time. 41 days later, the numbers told a story the internet hates. Bodyweight...

If physiology cared about your plans, coaching would be easy. You’d set the variables.Your body would comply.Everyone would clap. …But adaptation doesn’t work that way. I often joke that physiology is associated with every “bad” engineering word as it is nonlinear, anisotropic, messy, and constrained by stress, recovery, and timing in ways no spreadsheet can fully capture.This is why many lose fat for three weeks and then stall.Why performance jumps and then inexplicably dips.Why the “perfect...

Fasting is one of the most misunderstood tools in nutrition. People “out there” talk about it like it’s a moral test. As if the goal is to endure hunger long enough to earn metabolic salvation. Physiologically, fasting is not a diet per say, it is a metabolic stressor. A useful one, for sure, but only when placed correctly. When you remove food, you amplify signaling: catecholamines rise fat oxidation increases AMPK activity shifts insulin dynamics change That’s the upside. The downside is...

Most people still think creatine is just for bigger biceps and better deadlifts. That’s outdated. In this rebroadcast of my conversation with Dr. Eric Rawson, we dig into what might be the most underappreciated role of creatine: brain energy. We cover: How creatine influences cognitive function Why measuring brain creatine is so difficult The difference between animal models and real human data What we actually know (and don’t know) about concussion recovery Why creatine monohydrate has one...

A funny thing happens when people first encounter metabolic flexibility. They hear the term and immediately sprint toward the sexy parts. Carb cycling.Ketones.Fasted training.Fuel switching like a metabolic DJ. And I get it. I really do. Those are the parts that make you feel like you’re finally doing something sophisticated. But here’s the part nobody wants to hear: If you start there, you’re already behind. Every time. At the cellular level, metabolic flexibility is boring before it’s...

Real talk. In about 5 hours, the fast-action bonuses disappear. Not "maybe." Not "extended if we hit a goal." Gone. Here's what vanishes at midnight PST tonight: → The 6 Level 2 Advanced Modules This is the stuff I don't advertise. The deep work on adrenal fatigue, vegan athletes, hormonal testing, metabolic efficiency, the 80/20 rule, and adaptive cycles. These modules exist because after 20+ years of coaching, I realized the basics only take you so far. Eventually, you need to understand...
