About – 80 Twenty Nutrition

Hi, I’m Christy! I’m a registered dietitian nutritionist and an expert in helping people heal with real food. I’ll show you how to work with your body, not against it.

what I’m about

Here’s what sets me apart from all of the nutrition “experts” out there:


Science + Experience (the best of both worlds)

I became a registered dietitian nutritionist and got a Master’s degree in Nutritional Sciences so I could bring you the most up-to-date, evidence -based nutrition guidance out there. With over a decade of experience getting results for my clients, I’ve seen what works best and what just doesn’t.



I’m not going to force you to give up gluten, dairy, meat, grains, or any other foods for no good reason. I don’t follow a particular type of diet. If you want to follow a certain way of eating, I’d love to support you in doing so in a way that’s as nutrient-dense and has as much variety as possible.


Real Food First

Let’s harness the healing power of food! I won’t load you up with supplements and herbs (that’s a red flag, by the way). Save that money and put it towards groceries so you can focus on eating whole, nourishing foods. I only recommend supplements if I determine there is a true need that can’t be met with food.


Realistic and Sustainable

Weighing or measuring food, counting your macros, tracking what you’re eating, or (gasp!) cutting out your favorite foods isn’t going to work long term. My nutrition strategies are for real people, not robots!

You’re busy and you don’t want your diet to consume your life. I get that. All plans include wiggle room for celebrating with family, eating out with friends and going on vacation. And all of my recipes are easy and quick with you in mind.

WHAT IS THE 80 TWENTY RULE, ANYWAY? It’s not about diets. It’s not about calorie counting. It’s about choosing “healthy” foods 80% of the time and treat yourself to “other” foods 20% of the time.



No cookie cutters here! There isn’t one way of eating that works for everyone. You’re an individual and you should be treated like one. All of our courses, books and resources help you find what fits with your unique personality, lifestyle and goals.

my story

Why I Became a Dietitian

There is so much conflicting and confusing nutrition information out there. If you’re confused or frustrated by what you’ve tried so far, I hear you.

I’ve been there.

Over the years, I’ve watched my family suffer with cancer, diabetes and heart disease. They were disappointed with the lack of reliable information and support they received on how to manage their health problems with nutrition. I knew there had to be a better way.

In an effort to help them and to heal myself from IBS and prevent disease, I tried every diet out there. I lived through weight fluctuations and crashing mood and energy levels. Then my blood sugars crashed too.

Dealing with reactive hypoglycemia made it nearly impossible for me to eat in a way to help me lose the extra weight I had put on.

I continued searching for trustworthy nutrition information but wasn’t satisfied. That’s why I became a dietitian. I cut through the noise and deliver cutting-edge information that actually works.

I healed myself and

helped thousands of people do the same.
