Kristen MancinelliMS, RD

I’ve been a nutrition and public health professional for over 20 years, translating the science of how to be healthy into practical approaches people can use in their everyday lives and advocating for healthcare and food systems to do the same. In my private practice I see clients who want to lose weight or reduce body fat, manage midlife changes to their metabolism and physique, and improve biomarkers like cholesterol and glucose. I also see clients who want freedom from constant thoughts of food and wish to make eating less of a stressful event.

My training spans the science of the body and that of behavior change. I have a Bachelor of Arts in Chemistry from NYU and a Master of Science in Nutrition and Public Health from Columbia University. I am also a Registered Dietitian (RD). I’ve published two books: The Ketogenic Diet (2015) and Jump Start Ketosis: Intermittent Fasting for Burning Fat and Losing Weight (2018), though I don’t favor low-carb diets for everyone.

Nutrition counseling is highly personal. It goes well beyond macros and meal plans to understand the motivations and beliefs driving health behaviors and reshape them toward better outcomes. After 14 years of practice I am still amazed at how quickly this process can help people transform their lives.

My clients say I am “insightful in ways [they] didn’t expect,” my “non-judgmental approach makes all the difference,” and they “haven’t felt this good since high school!”

The Ketogenic Diet by Kristen Mancinelli

Ulysses Press, 2015

The ketogenic diet works by restricting carbohydrates to the point where insulin stays low and the body shifts from using glucose to burning fat instead. Appetite drops and food noise quiets. Symptoms associated with insulin resistance tend to improve. Keto is difficult to do and isn’t for everyone, but it’s an incredible tool in the right circumstances.

Jump Start Ketosis by Kristen Mancinelli

Ulysses Press, 2018

Intermittent fasting is a very effective way to reduce caloric intake and give the body a break from the excess stream of insulin that results from eating throughout the day. The benefits to cardiometabolic health are significant. Diet quality and resistance training should be high priorities for anyone on a reduced calorie diet, especially those practicing intermittent fasting or taking a GLP-1.

Testimonials

Kristen guided me through a year-long journey of creating habits to support my weight loss and lower my A1c. Her insights and guidance made the process both comfortable and challenging — and led me to not only achieve my health goals, but also to a lot of personal growth.

Kristen helped me eat better, and ultimately feel better, when I didn’t have much interest in eating and had pain when I did. She has consistently offered me simple and effective advice to support my daily routine, and she always has a solution when I feel like something is off balance. This has made all the difference.

When I began seeing Kristen, my control of my diabetes was erratic and certainly uninformed. Kristen took the time to explain how my eating habits, my exercising and my hunger were all inter-related, and I have been very successful in keeping my glucose in check, as well as becoming stronger, and a better cook too!
