What Should You Really Be Eating on GLP-1 Medications?
Losing weight is only part of the picture.
Are you eating less but feeling exhausted, constipated, or worried about losing muscle? Or do you want to get off your GLP-1 medication without gaining the weight back?
GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound can make weight loss easier, but they don't necessarily teach you how to nourish your body or maintain your results.
I'm a licensed, board-certified nutritionist specializing in metabolism, thyroid function, digestive health, and sustainable weight loss. I help clients develop personalized nutrition plans that support their health while taking GLP-1 medications - and prepare them for what comes next.
Losing Weight Is Great. But How Are You Feeling?
GLP-1 medications can make it much easier to eat less, but that doesn't always mean your body is getting what it needs. Even when the scale is moving in the right direction, you might be experiencing problems that deserve attention.
Low Energy & Fatigue
Eating too little for too long can leave you exhausted and contribute to metabolic adaptations that reduce energy expenditure.
Muscle Loss
Not all weight loss is fat loss. Without adequate nutrition and resistance exercise, you may lose valuable muscle along with body fat.
Constipation & Digestive Problems
GLP-1 medications slow stomach emptying and can contribute to nausea, bloating, and constipation. Your food choices and eating patterns can make a difference in how you feel.
Fear of Regaining Weight
What happens when you're ready to stop taking the medication? Hunger often returns, and weight regain is common. Developing sustainable nutrition habits now can help you prepare for that transition.
You Don't Need Another Restrictive Diet.
You need a personalized approach that supports your metabolism, preserves muscle, and helps you build healthier habits for the long term.

Let's Build a Nutrition Plan That Actually Works for You
Whether you're currently taking a GLP-1 medication or thinking about stopping, I'll help you develop a personalized eating plan based on your metabolism, body composition, activity level, and health goals.
We'll look at your calorie and nutrient needs, carbohydrate, fat, and protein intake, digestion, thyroid health, and any challenges that may be making weight management difficult. You'll leave with practical recommendations tailored to your body and the foods you enjoy - not another generic diet.
My goal is to help you feel better, preserve muscle, support your metabolism, and develop eating habits you can maintain for the long term.

Hi, I'm Marissa!
I'm a licensed, board-certified nutritionist with over 20 years of experience studying nutrition and metabolism. I specialize in helping people improve their metabolic health, thyroid function, digestion, and body composition without relying on endless restrictive diets.
I've seen firsthand how chronic under-eating can affect energy, muscle, hormones, and digestion. And with GLP-1 medications making it easier than ever to eat very little, I believe good nutritional guidance is more important than ever.
My goal is to help you lose excess body fat without sacrificing your health—and develop an eating plan you can actually maintain, whether you're currently taking a GLP-1 medication or preparing to stop.
