Meet Ella Davar, RD
Clinical gut health dietitian. Creator of the Gut-Brain Method™. The person who fixed her own gut — and built a clinical system from what she learned.
I didn't become a dietitian because I had the answers. I became one because I was out of them.
For years I dealt with chronic bloating, low energy, and symptoms that didn't match any diagnosis I was given. I had the training — NYU, Mount Sinai — and I still couldn't figure out what was wrong with my own body. So I went deeper. Functional medicine. Microbiome science. Psychoneuroimmunology. And eventually, I pieced together a clinical framework that actually worked. Not just for me. For the 20,000+ clients I've worked with since.
That framework is the Gut-Brain Method™. It's not a wellness trend. It's a clinical protocol that starts with your lab results and ends with a plan your body can actually follow.

What is the Gut-Brain Method™?
Most health programs treat symptoms. The Gut-Brain Method™ treats causes.
It's a clinical protocol built on three things most wellness programs skip: functional lab testing (not standard blood panels — actual gut microbiome analysis, hormone mapping, and metabolic biomarkers), evidence-based nutrition science applied to your specific results, and neuroscience-informed support for the gut-brain axis that drives mood, sleep, and metabolism.
The result is a plan that fits your body. Not a template. Not a protocol built for someone else's labs.
This is why clients come to me after seeing other practitioners. Not because those practitioners were wrong — but because they were working without the right data.

The Gut-Brain Method™ Program
approach to health
I don't believe in one-size-fits-all nutrition. I believe in bio-individuality — the idea that your gut microbiome, genetics, metabolism, and history make your nutritional needs genuinely different from anyone else's.
That means I don't prescribe the same protocol twice. Every program starts with your data. Every recommendation follows from what your body shows us.
I also believe that healing your gut changes more than your digestion. Mood, energy, skin, hormones, and even how you think about food — all of it shifts when your gut is actually working.
Your Health by Gut-Brain Method™
Digestive Health
if you are struggling with frequent bloating, diarrhea, constipation, acid reflux, SIBO, IBS, inflammatory conditions, candida, etc.
I offer my clients life-changing digestive health protocols with personalized diets, functional nutrition, and supplement programs according to various assessment tests such as comprehensive stool test result, GI map

If you are struggling with autoimmune conditions, allergies, low moods, unexplained fatigue, and vulnerability to colds and flu. I can help you to maintain a young, healthy, and beautiful glow which is possible with proper nutrition and lifestyle changes. You’ll learn to incorporate key nutrients and superfoods to sustain your youthful glow and stamina. Together we will develop a lifestyle plan (even for busy folks)aimed at you looking and feeling your best. I’ll introduce you to some of the world’s healthiest foods and teach you how to find what’s healthiest for your unique body!
Deconstructing Cravings and Food Addiction
Cravings and addiction play a critical role in understanding what your body needs and shouldn’t be ignored. When you learn how to deconstruct your cravings and understand what they’re really telling you, you will be able to reclaim a sense of balance, harmony, and confidence.
Weight Loss
Losing weight and keeping it off can be difficult. If you’ve tried everything and still find yourself spinning your wheels, Diet and cleanses are not the answer for permanent weight loss. I can help you make sustainable lifestyle changes according to your body’s needs and keep you motivated so you can lose weight and learn how to keep it off for good. Together we will create a 28-day meal plan around your cycle.
Bio-Individuality™
I approach each client as a unique individual. Bio-individuality is the idea that each of us has unique food and lifestyle needs. Working on the principle of bio-individuality, I’ll support you in making changes based on your unique needs, lifestyle, preferences, and ancestral background according to your genetic tests, microbial makeup, and metabolism.
Healthy Mindset with Guided Meditations
It’s easy to overlook everything that contributes to our sense of nourishment and fulfillment. It’s not just the food we eat that affects our health, but all of the other factors present in our daily lives. Healthy relationships, a fulfilling career, regular physical activity, and a spiritual awareness are essential forms of nourishment. Through Food Therapy (guided meditative hypnosis) you are able to create a vision for your life, heal, and let go of food trauma to create a new version of yourself.
