Feeling at peace with our eating habits and our bodies can feel rare in a world full of constantly changing messaging about what we should eat, how much, how often, etc. Working on your relationship with food, exercise, and your body can be transformational in building trust in your body's ability to tell you what it needs and your ability to listen. If you're tired of swinging from one end of the eating spectrum to the other, I can help!

You are the expert on you, but don't know where to start. The expanse of the internet often provides confusing, unprofessional, and potentially harmful information about nutrition, weight, and health. I am not focused on "perfect" nutrition. Does it even exist? Let's look at the health and weight messages that influence you and find out what's relevant to YOU. Person versus population. We will have an honest conversation about what you need to focus on and how to make it happen. People expect a dietitian to judge them - but most people leave my office with hope, feeling like they are supported in making incremental change.

I am a Massachusetts Chinese Medicine doc and Licensed Dietitian. I studied Functional Medicine before it became a buzzword 15+ years ago, although no longer use expen$ive testing but focus on Chinese Medicine diagnosis and treatment. I have a special interest in the areas of digestive issues such as bloating, gas, diarrhea, IBD, IBS, and reflux but see SIBO as a symptom rather than a cause. I do not give out SIBO diets, but work on fixing the underlying issue. If you have GYN issues such as heavy bleeding, menopausal symptoms, or pain during periods I can almost certainly help you with Chinese Medicine.

My primary goal: help you love food. I grew up in a household where food was fun, varied, and adventurous. My Mother was a home economics teacher turned preschool teacher.

There's an overwhelming amount of messages out there that tell us what or how we "should" eat. These messages tell us to abide by prescriptive “diets” or practices, and can keep us from trusting or connecting with ourselves. If you’re ready to break free from diet culture, and hope to restore your relationship with food, body and/or movement, but are wondering where to start, I’m here to help! I work with a variety of age groups, from adolescents to older adults. I work with those who are recovering from diet culture, disordered eating and eating disorders.

We live in a challenging time in regards to food, nutrition and body image. We are submerged in nutrition myths, quick fix diets and “perfect” bodies on social media. We feel immense pressure to change our bodies, and work tirelessly to eat and move in a way that will do just that, only to find ourselves defeated, exhausted, and back where we started. Over time, we forget that eating and movement should be pleasurable and nourishing.

Polycystic Ovarian Syndrome (PCOS) Nutritionists and Dietitians
What is Polycystic ovarian syndrome (PCOS)?
Polycystic ovarian syndrome (PCOS) is a condition characterized by hormonal imbalance, leading to symptoms such as irregular or absent periods, weight gain, excess hair growth, infertility, and acne. The exact causes of PCOS are not well understood, but it is believed to result from a combination of genetic and lifestyle factors, including stress and nutrition.

How is PCOS treated?
PCOS is typically treated with a combination of medication and lifestyle changes. Many individuals with PCOS are prescribed birth control medication to help regulate the abnormal hormone levels associated with the condition. With regard to lifestyle modifications, healthcare professionals often recommend maintaining a balanced, healthy diet and engaging in regular physical activity. This is particularly important for women diagnosed with obesity or diabetes, as weight loss and improved insulin regulation can significantly alleviate PCOS symptoms.

What diet is best for people with PCOS?
In general, experts recommend a plant-based diet high in fiber, healthy fats, and lean protein as the best nutritional approach to managing PCOS. Because women diagnosed with PCOS are at a higher risk of specific conditions, such as type 2 diabetes, hypertension, and heart problems, a diet that helps prevent such conditions can be highly effective. The "Mediterranean diet," characterized by the consumption of lots of healthy fats, vegetables, beans, and whole grains is one common diet with evidence supporting its efficacy in preventing cardiovascular and metabolic diseases. In addition, other lifestyle modifications that support weight management and healthy insulin levels—such as exercise, smoking cessation, and alcohol consumption reduction—are often also incorporated into PCOS treatment.

What foods should people with PCOS avoid?
Due to the high blood sugar levels and insulin resistance characteristic of PCOS, experts typically advise individuals with PCOS to avoid foods that cause large blood sugar spikes, such as sugary snacks and refined carbs like white bread. Instead, they recommend consuming foods rich in healthy fats, whole grains, and fiber, which can help stabilize blood sugar levels. Individuals with PCOS may also find that certain foods trigger their symptoms. Therefore, identifying and avoiding these specific foods can be important for reducing symptom severity on an individual level.
