A la carte Programs for Purchase

Eat to Achieve

3-week food plan offering nutrition education & lifestyle medicine.

21 days of nutrition education and lifestyle support offered in a convenient self-study program. This program teaches you how to shift toward a whole-foods eating approach while freeing yourself from the diet mentality to support overall health.

With Eat to Achieve™, you will learn a lot about choosing food, how to shop, how to seek out ingredients, how your stress response works, how digestion works, and what you can do to help it all along. There are 3 levels within the program to allow you to meet yourself where you're at. There is even an option to use this as an elimination-style diet to suss out food sensitivities. Content is rolled out daily, along with a 100+ page book to kick things off (the book is available immediately upon purchase). 

Shift away from addictive, potentially allergenic, and difficult-to-digest food and embrace whole foods. Learn how to crowd out unhealthy habits while boosting your existing good habits. This program will create the space for positive and sustainable changes to your diet and lifestyle. 

This food plan removes foods that may trigger an immune response. It supports brain health, gut health, detoxification, blood sugar stability, and combats inflammation. You start to pay attention to the sourcing of food and understand why it matters. You WILL NOT count calories, weigh food, or measure portions. You WILL reprogram your body's hunger and satiety cues, keeping you from overeating. 

 If you’re looking to adopt a real food lifestyle, and learn the ins and outs and the how-tos, Eat to Achieve™ is perfect for you.

Carb Compatibility Project™

An intuitive 4-week plan to determine your body’s unique carbohydrate needs and end the carb confusion.

Use real food, and low-carb principles to balance blood sugar, crush cravings, heal digestive issues, gain energy, lose weight, and feel great! This intuitive 4-week online nutrition plan helps you determine your body's unique carbohydrate needs and end the carb confusion once and for all. 

The Carb Compatibility Project™ rolls out weekly content over 4 weeks: food templates, weekly lessons, and weekly intuitive eating practices.

The Carb Compatibility Project™ doesn't spend much time going over the same concepts of Eat to Achieve™. This project assumes that you're already familiar with the principles of a whole foods diet and takes them a step further, talking more specifically about calories and carbohydrates, and dialing in more specific macronutrient ratios. We also explore higher-level concepts, including blood sugar regulation, hormonal health, gut health, pre-and post-workout nutrition, and more. The Carb Compatibility Project™ is designed with low-carb exploration in mind. We start with a moderate-carb diet and slowly work down to a low-carb diet. There is a chance toward the end to experiment with a very low carb/high fat (aka keto) way of eating.

If you’re already comfortable with a whole foods diet but want to continue to experiment and dial in your unique nutrition, the Carb Compatibility Project™ is perfect for you.

Body Intentions Breakthrough

A brain-based course to rewire for weight loss, health goals & body success with lifetime access for continuous programming: The more you do this, the more you will see breakthroughs, shifts & results. And you can continue to use these techniques for ANY future goals.

In this course, we’re going to be reprogramming, re-patterning, and rewiring the brain using very specific health techniques to get you to where you want to go.

You will learn about why building new neurological pathways leads to biological shifts that last (and how to do it), and you’ll receive a guided breathwork practice for somatic release & breakthrough, plus a guided quantum timeline goal setting.

This course comes with additional resources: a workbook with specific journal prompts for rewiring, a guided hypnosis for daily goal infusion, bonus meditations, a bonus Weight Loss for Women class, a bonus Unpacking Body Beliefs class, and a curated list of relevant podcast episodes hand-picked by Erin.

Your Hormone Revival™

3 month comprehensive balancing program for female adrenal, thyroid, and hormone health. Understand your hormones and unlock the root of imbalance with educational modules, food and lifestyle medicine, community support & optional functional labs & individualized protocol.

Your Hormone Revival™ blends the best of both worlds: the education platform and community of a group program, with optional access to functional lab testing and analysis for an additional fee. Over the course of 12 weeks, educational modules are rolled out through videos, audios, and transcripts so you can watch, listen or read depending on your learning style.

This program is the perfect fit for you if you experience any of the following symptoms or imbalances: fatigue, burnout, anxiety, overwhelm, sleep issues, weight loss resistance, menstrual cycle irregularities, painful periods, PCOS, hormonal issues or thyroid dysfunction.

This program is currently offered through The Funk’tional Nutrition Collective.

The Boundaries Course

Prevent burnout through defining and upholding boundaries. Uncover the blocks of why boundary setting is so freaking hard.

As I always say, boundary setting IS healthcare. This is a game-changer of a program that you don’t want to miss.
