Why You Need This Checklist

What if you found out that hitting your daily protein goal still isn't enough to actually build muscle? That's not a hypothetical — it's what Thomas DeLauer breaks down in one of his most eye-opening videos, and once you understand the mechanism, you can't unsee it.

Here's the uncomfortable truth: your body doesn't care about your total protein number. It cares about a single threshold. Every meal you eat is either flipping a switch that builds muscle or it isn't — and most people are landing just under that line, meal after meal, without realizing it. You could be eating 100 grams of protein a day, buying expensive supplements, and still slowly losing muscle. That's not a motivation problem. That's a trigger problem.

Imagine waking up knowing that every meal you eat is actually working. That your protein is hitting the threshold, your muscle-building switch is firing, and your body is doing exactly what you're asking it to do. You feel leaner, stronger, and more in control — not because you're eating more, but because you finally understand how your body responds to what you're already eating. That's what this system unlocks.

Thomas DeLauer has spent years breaking down the science of muscle, fat loss, and metabolic health into strategies real people can actually use. He references peer-reviewed research — studies from the Journal of Nutrition, the Journal of Physiology, Clinical Science, and the American Journal of Clinical Nutrition — and translates it into practical steps anyone can follow. This isn't bro-science. This is the kind of evidence-based guidance that separates people who spin their wheels from people who actually get results.

This PDF checklist takes everything Thomas covers — the leucine threshold, protein distribution strategy, the age-related anabolic resistance problem, and the three non-protein compounds that amplify your results — and turns it into a clean, actionable reference you can use starting today. You'll know exactly how much leucine you need per meal, how to space your protein for maximum muscle protein synthesis, which protein sources carry the highest leucine content, and which supplements to stack to make your entire system more responsive. No more guessing. No more wasted meals. Just a clear protocol that works.

What's Inside — Preview

Every checklist item comes with actionable notes to guide you — things like "Don't forget to do this before you start," "Avoid this common mistake," or "Set a reminder for 30 days out." Nothing vague, just clear next steps.

LEARN Understand that leucine — not total protein — is the trigger for muscle protein synthesis via the mTORC1 pathway
MEASURE Target 2–3 grams of leucine per meal if you are under 40 years old
MEASURE Increase your per-meal leucine target to 3–4 grams if you are over 40 years old
DECIDE Choose whey protein as your primary protein source to most reliably clear the leucine threshold
BUY Select a clean, third-party tested whey protein brand — Thomas recommends Purity (Puring) due to contamination concerns in the industry
