REVVed: to have made something more active or energetic.
Seattle Registered Dietitian
Meet Your Dietitian.
Hi, I’m Marissa Beck, MS, RDN, Registered Dietitian, Certified Intuitive Eating Counselor, and Founder of REVV Health!
I’ve been a registered dietitian since 2009, working with thousands of people whose health histories, relationships with food, and goals look nothing alike.
From eating disorders and chronic dieting to medical nutrition therapy, sports nutrition, and weight concerns, I’ve learned that you can’t understand someone’s nutrition needs without understanding their story.
I don’t believe in handing you another set of food rules or deciding what you should want for your body. I believe in asking better questions, listening closely, and helping you make informed choices that support your health and your life.
You bring your story. I’ll bring the science, experience, and curiosity 🙂
And yes, we have a lot of fun along the way.
Behind the Scenes!
Who I Am
Hi, I’m Marissa Beck (and I really love food).
I say that because people tend to assume dietitians live on kale salads and protein shakes. Sorry, Charlie. I’m a big believer in enjoying ALL kinds of food, especially chocolate gelato.
I’ve been a Registered Dietitian Nutritionist since 2009, working with everyone from executives at major tech companies to athletes, parents, kids, and people navigating complicated relationships with food.
After years in corporate wellness, I started REVV Health because I wanted to do nutrition care differently. I wanted the freedom to look beyond the diagnosis, the food log, or the number on the scale and really get to know the person sitting across from me.
A little more about me, originally from Queens, NY (Let’s go, Mets!), a mom of two girls, and a lifelong athlete. I believe in moving my body in ways that are fun, freeing, and occasionally a little fierce.
My Philosophy
I believe you can care deeply about your health without letting food or your weight consume your life. You deserve to feel heard and respected, no matter where you are in your journey. I approach nutrition with curiosity and a belief that we’re all capable of learning and growing, myself included. Together, we’ll build on what you know, challenge what no longer serves you, and find a way of eating that supports your health and the life you want to live.
Client 💗, Features, & Speaking
Throughout my career, I’ve had the opportunity to write for and contribute my expertise to publications including EatingWell, Today’s Dietitian, Seattle’s Child, and more. I’ve also had the pleasure of working with employees at Microsoft, Nintendo, and local corporations and nonprofits, making nutrition education practical, engaging, and actually enjoyable.

Don’t Just Take My Word for It.
“You really have a talent to bring nutrition education into a format that is easy to understand and motivates me to try to hit tricky goals, like fiber, that I’d otherwise not think about. I really appreciate your down to earth, no fuss advice!”

My Values for Our Work Together
Compassion
This is a no-judgement zone. I understand the deep struggles with food and body image that many people face and approach our work together with compassion.
Body Autonomy
Your body. Your goals. Your choices. I’m here to help you make informed decisions grounded in evidence and guided by a harm-reduction approach.
Flexibility
Real life rarely follows a perfect plan. We’ll find ways to care for your health that leave room for living.
Growth
There’s always more to learn. I bring that mindset to every session, and I’m still learning right alongside you.
Inclusion
You deserve respectful nutrition care at every body size, with your experiences and concerns taken seriously.
Family
The way we talk about food and bodies can echo for generations. I want to help change that conversation, and do so even in my own family everyday.
Why I Do This Work
I never thought I’d wake up one day and not care what the scale said. That I could go an entire day without counting calories, questioning every bite, or feeling like food controlled my life.
But here I am. And I want you to know that kind of freedom is possible.
As a high-achieving student and collegiate athlete, I spent years going after perfection while struggling with an eating disorder, PCOS, and IBS.
In 2005, an injury forced me to stop running just after qualifying for the Boston Marathon. It was a turning point that made me confront how much I needed to heal.
And I did. Fully.
I was fortunate to receive professional treatment and support in my twenties. By 2008, I had fully recovered from my eating disorder. And when I say fully, I mean fully.
For nearly two decades, I haven’t struggled with food, weight, or the thoughts and behaviors that once consumed my life. Even through some of life’s most difficult experiences, those old patterns never returned.
I never take that freedom for granted, especially knowing that not everyone has access to the care and resources that helped me recover.
From Lived Experience to Clinical Expertise
My experience helped shape my decision to pursue a master’s degree in Nutrition and Exercise Science and become a registered dietitian.
Since 2009, I’ve worked with thousands of people navigating eating disorders, chronic dieting, medical conditions, sports nutrition, and weight concerns.
And here’s what nearly two decades of practice have taught me: People are complicated. Nutrition care should be able to handle that.
Sometimes people need more structure. Sometimes the rules themselves are making things worse. And sometimes, improving physical health means addressing someone’s relationship with food at the same time.
I’ve done the personal work to make sure my own history doesn’t become someone else’s treatment plan.
My recovery has given me perspective, but my years of clinical practice have taught me how to help others find their own way forward.
Today, as a mom, I’m also raising the next generation to enjoy food, respect their bodies, and know that life has so much more to offer than worrying about either.
That’s why I do this work. And why I take the responsibility of doing it well so seriously.

My Bio
Hi, I’m Marissa Beck, MS, RDN!
I’ve been a registered dietitian nutritionist since 2009, helping thousands of people navigate nutrition, improve their health, and build a better relationship with food. My experience spans eating disorders, chronic dieting, intuitive eating, medical nutrition therapy, sports nutrition, and the many ways our health and eating behaviors intersect.
Before founding REVV Health in November 2022, I led nutrition programs at companies like Nintendo and Microsoft and worked with employees at Google, Facebook, and other tech companies. My career in corporate wellness began in New York City, where I developed and managed health initiatives at a fast-paced eCommerce startup.
I earned my Master of Science in Nutrition and Exercise Physiology from Columbia University and my BA from Tufts University. After working with thousands of people, one thing is clear: even when symptoms look the same on paper, the person behind them rarely does. That’s why I take the time to understand your story before figuring out what might help.
As a former gymnast and collegiate athlete, I’ve always loved movement. These days, you’ll find me on my Peloton, skiing, or hiking around Seattle, where I live with my husband and two daughters.
And yes, I’m a proud foodie. I love exploring different cultures through cooking and sharing good meals with family and friends. I believe food deserves to be enjoyed, and there’s so much more to life than spending it worrying about what’s on your plate.
Looking for nutrition support for yourself, your family, or your team? I’d love to connect!
“Marissa is amazing. She is empathetic to all the realities of life when it comes to eating in any stage of life. I found her in conversation about my weight struggles for menopause. She said she had tools and I said YES PLEASE. My biggest fear was moving from a M to a L in my shorts. After hiring her, I actually love and have confidence in my body at any size.”
