My name is Carolina (Carol) Guizar and I love puns. I also love eating and consider myself an authority on it. From these two loves, Eathority was born.

I have been a professional eater since birth. My most vivid memories of childhood revolve around food---my Mexican grandmother's plump hands shaping cornmeal into the perfect tortilla, me standing on tip toe as I watched them slowly rise on the stove; or my mother concocting savory breakfast burritos from leftovers in the fridge, me gobbling one down as I drove my brothers to school. I never gave much thought to what I ate and developed an affinity for all things fast food, but would also have balanced meals at homes. I look back on it now and realize it was an inherently healthy relationship with food---I was active, ate mostly whole foods and did not feel shame about my food choices. 

But some time after college, I strayed from this. I stumbled upon the raw food diet, then the Paleo diet. Food fears abounded and I was terrified to eat things like white rice, bread and sugar. I would read books on nutrition, written by non-health professionals, and dole out advice to anyone who would listen. But there was always this nagging voice inside: is the information in these books true? Are my food fears warranted? Will I never be able to eat my favorite foods without guilt that I'm harming my body? 

I became a dietitian because I needed clarity on the science of nutrition and wanted to provide people with accurate information to make informed decisions. Along the way, it also became apparent that people need help feeling confident in their food decisions, learning to trust themselves around certain foods. You can easily eat yogurt and fruit in the morning, but how do you manage a night out with alcohol and fries? How can you have cake and meet health goals, too? 

Whether you're a student, business traveler or working mom, I marry sound nutrition information with practical recommendations that fit into your life. We will also rewrite your food story as we confront old habits and thought patterns to help you achieve a more peaceful relationship with food. You will start to clue into how food makes you feel and make decisions based on what you want and need, versus what you think you should have. We will clarify your health goals and implement sustainable changes that last a lifetime, so you can indulge in your favorite foods and never feel like you're on a diet again. Let's cheers to that!

Eathority's Approach

Eathority nurtures collaborative partnerships with clients to help them achieve nutrition goals that are safe and sustainable. This is not a practice that promotes “cleanses” and “detoxes”. Eathority is about real food and evidence-based practices to prevent or manage chronic disease. No food is restricted, but nutrient-rich choices are the central focus and emphasis is placed on mindful and intuitive eating. 


Is Eathority right for you?

Eathority‘s programs are tailored to your needs and lifestyle, but flexibility and open-mindedness are key to your success. Curiosity, self-introspection and a willingness to address behaviors that undermine long-term health goals will also lead to ongoing results.
