Ready to get better results for your clients?

We’re about to teach you everything we know about the #1 most-searched (and misunderstood) nutrition coaching topic: Macronutrients.

Most people are unsure about how adjusting their macros can help them reach their goals. And most coaches are confused about how to advise them. But not you. Not anymore.

When it comes to macros, it’s not all about the numbers.

This is something a lot of coaches miss, but it’s so important: Macronutrients are about people as much as they are numbers.

People with their individual physiology… complicated lives… and wildly varying degrees of experience and motivation.

Any coach can give their client some numbers to follow. But a great coach knows how to translate those numbers into smart action steps and life-transforming results.

With this PN Definitive Guide: The Science and Practice of Macros, we’ll show you the methods we use to help our clients achieve their loftiest goals.

Not only will you gain a metric ton of macronutrient knowledge, you’ll get access to the best, most advanced tools to use with your clients.

So whether you just want to know more for your own nutrition and body composition goals, or you have a full roster of paying clients who expect results, we’ll give you everything you need to succeed.

How the guide works.

Once you register, you’ll get instant access to the entire digital guide via our online learning portal. You can access it from any device, anytime you want.

The guide is structured into three units...

Unit 1: The science of macros

This is your crash course in truly understanding what affects energy in and energy out, and the science of how protein, carbs, and fat can affect the equation. It’s the “why” you need so you can better implement the “how.”

Unit 2: How to determine and calculate macros

You’ll learn step-by-step instructions for calculating and tracking macros using outcome-based decision making. This isn’t just about macro math and checking boxes. It’s the art of fine-tuning: how to dial-in the numbers based on the progress you’re seeing.

Unit 3: How to coach macros

These are the elite coaching skills that turn good coaches into great coaches. Because even if the numbers look perfect on paper, they still have to work in the real world… with the progress-blocking physical, mental, and emotional challenges people face every single day.

With each unit, you’ll get:

  • An in-depth Research Guide that reviews the most up-to-date knowledge
  • A Quick Reference Guide that quickly covers key concepts
  • A video lecture (plus audio and transcript) that helps explain macros and their application
  • An Expert Roundtable podcast with PN experts discussing core ideas and “behind the scenes” tips on understanding and applying macros
  • Additional resources such as handouts, assessment forms, worksheets, and our suggestions for further reading and learning

Case study

The best way to solidify what you’ve learned is to practice it. So we’ve included a detailed case study (based on real clients) to help you apply the knowledge from the guide.

Quiz

You’ll get an opportunity to test your knowledge and prove to the world that you’ve mastered the material. (This is totally optional. And don’t worry: You will master the material.)

BONUS: Precision Nutrition Calculator, Professional Edition

Get access to the most comprehensive calorie, portion, and macro calculator anywhere. Simply enter your client’s age, weight, activity level, exercise habits, goal, timeline, eating style… and it will instantly calculate everything for you.

Built specifically for health and fitness pros, this world-class tool is full of advanced features and options, including the ability to fully customize your client’s eating plan—down to the most granular detail.

The best part? You can instantly download, print, and share these plans with your clients featuring your logo—for a personalized, professional touch

“This calculator is GENIUS. It’s going to save coaches a ton of time and guesswork.”

-Tony Gentilcore, Men’s Health writer and strength coach
