The Mind Behind the Meals

Meet Karen Grecea, MS, RD

Registered Dietitian. Critical Thinker. Compassionate Guide.

Hi, I’m Karen, registered dietitian, personal trainer, former ICU dietitian, and founder of Bite Into Balance. I created this practice to provide a supportive, practical, and approachable space for clients to feel empowered in their nutrition journeys. After years working in critical care and personal training settings, not to mention dealing with my own health journey, I witnessed the confusion and frustration patients experienced when trying to follow generic nutrition advice. I knew there had to be a better way.

My Story

In my first year of undergrad, I was new to lifting weights and, like many (as I was an athlete before college), turned to social media for guidance. I found an influencer who called herself a “nutritionist,” not realizing at the time that she had no formal credentials. 

Desperate for direction, I signed up for her coaching. 

Instead of providing real support, she put me on an extreme diet that left me undernourished and overtrained. My body fat plummeted to unhealthy levels, and I lost my period for nearly a decade. What started as a desire to get stronger spiraled into years of obsessive body manipulation, over-exercising, and under-eating, leading to orthorexia, chronic stress, and ultimately, an autoimmune disease. After undergrad, I was working as a personal trainer at Equinox, helping others reach their fitness goals, all while struggling with my own health.

That’s when I had a pivotal realization: training wasn’t enough. I needed to understand nutrition, not just for myself, but to help others avoid the same pitfalls I had experienced.

By 2019, I was diagnosed with Hashimoto’s hypothyroidism, and it became clear that the damage I had done to my body wasn’t just temporary.

I became a registered dietitian, diving deep into the science of nutrition and metabolism. But even after years of conventional nutrition training, I felt like something was missing. Doctors focused on treating my lab results, not my symptoms. The standard approach didn’t provide the answers I needed, so I took matters into my own hands. I explored functional and integrative nutrition, questioned traditional medical approaches, and learned to advocate for myself in the healthcare system. This journey led me to finally regain control over my health, resolving lingering and sometimes debilitating symptoms of my Hashimoto’s.

Now, through Bite Into Balance, I aim to help others navigate their own health journeys without extremes, misinformation, or quick fixes. My approach blends functional and conventional nutrition, empowering clients with evidence-based strategies that are personalized, realistic, and sustainable. Whether it’s managing a chronic condition, improving metabolic health, or fostering a healthier relationship with food, I believe in guiding people toward balance—one bite at a time.


My experience taught me that nutrition isn’t just about numbers, weight loss, or aesthetics. It’s about fueling your body, reclaiming your health, and feeling your best—without obsession or restriction.

I’m here to help others find that balance, so they can feel confident, energized, and empowered in their own skin.

what's the difference?

Dietitian vs. Nutritionist

It’s easy to confuse the two, but they’re not the same. A registered dietitian (RD or RDN) is a credentialed expert in the field of nutrition. To become an RD, one must complete an accredited academic program, a supervised clinical internship, and a national board exam. RDs are licensed professionals required to maintain continuing education and uphold strict standards of care.

In contrast, the title “nutritionist” is unregulated in many states, meaning anyone can call themselves one without formal training or certification. When you work with a registered dietitian, you can trust that your care is grounded in evidence-based science and tailored to your specific health needs. Your well-being deserves that level of precision, care, and credibility.
