Kristen Mancinelli, RD · Weight Loss · Metabolic Health

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

Nutrition counseling is highly personal. It goes well beyond macros and meal plans to understand the motivations and beliefs driving health behaviors, identify a client’s primary health risks and concerns with food, and work within the context of their life to create better outcomes. After thirteen years of practice I am still amazed at how quickly this process can help people transform their lives.

My training spans health science, research and analysis, and behavior change. I have a bachelor’s degree in chemistry from NYU and a master’s degree in nutrition and public health from Columbia University, and I am a registered dietitian (RD).

My clients say engaging with me is “refreshing,” I am “insightful in ways [they] didn’t expect,” my “non-judgmental approach is very helpful,” and they “haven’t felt this good since high school!”

If you’re looking for guidance to improve your health or eating habits and want to see if we’re a match, send me a text or book a no-commitment discovery call here.

Who this is for

Clients come to me when their health becomes a priority. Here are some common reasons.

A concerning lab result or new diagnosis.

You have an elevated A1c, triglycerides, or an abnormal lipid test (e.g., LDL, HDL); or a new diagnosis (e.g., prediabetes, PCOS, metabolic syndrome), and you want to improve things before medication becomes necessary.

Signs of insulin resistance.

You want to improve insulin sensitivity and glucose control through diet and training.

Midlife shifts in body composition or metabolic health.

You're noticing changes in energy, weight, or how your body responds to food, and you want to change the trajectory rather than accept gradual decline.

Using a GLP-1 medication.

You want to preserve muscle mass and bone density, support your metabolism, and ensure the weight you're losing is primarily fat.

Coming off a GLP-1 medication.

You've had significant changes in your body weight, and you want a strategy to maintain your results.

Books

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. Metabolic markers and symptoms associated with insulin resistance improve. Keto isn't for everyone, but it's an incredible tool in the right circumstances.

Intermittent fasting is a very effective way to reduce caloric intake and give the body a break from the constant stream of insulin that comes with eating throughout the day. The benefits to cardiometabolic health are significant. Diet quality and resistance training are priorities for anyone seeking good health, including people practicing intermittent fasting or those eating less while on 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!
