How to support your body and avoid common pitfalls from a Registered Dietitian with 15 years of experience.
Medications like Ozempic, Wegovy, and Zepbound are being used more frequently for metabolic conditions, including insulin resistance and PCOS. While they may reduce appetite and lead to weight changes, I also see a lot of confusion around how to actually support your body while taking them.
What often gets missed is that how you eat and move while on these medications plays a major role in how you feel, what type of weight is lost, and what happens long-term.
When appetite is significantly reduced, it can be easy to unintentionally under-fuel, skip meals, or rely on the medication alone. Over time, this is where I often see people run into problems like muscle loss, low energy, and more pronounced side effects.
The nutrition do’s and don’ts while on a GLP-1
Do:
- Use the medication as a tool – not a replacement for balanced nutrition
- Eat consistently throughout the day and avoid long gaps without fueling
- Prioritize protein to help preserve lean muscle mass and support metabolism
- Include regular movement – especially strength training – to maintain muscle
- Stay well hydrated to support digestion and reduce GI side effects
- Listen to your hunger and fullness cues and build meals around them in a structured way
Don’t:
- Skip meals or go long periods without eating
- Fall into a binge–restrict cycle
- Rely on the medication without supporting nutrition and lifestyle habits
- Avoid exercise or assume weight loss alone is enough
When these patterns show up, the result is often what many clients refer to as “the wrong kind” of weight loss. The scale may go down, but a larger portion of that loss can come from muscle rather than fat.
This can lead to a slower metabolism, decreased strength, fatigue, and a higher likelihood of weight regain if the medication is stopped—making it feel similar to what many people experience with chronic dieting.
I also see a higher incidence of side effects when the body isn’t adequately supported. These can include constipation, nausea, hair loss, brittle nails and skin, and hypoglycemia – which may increase the risk of dizziness or fainting. Rapid changes in weight combined with loss of muscle and facial fat can also contribute to what people refer to as “Ozempic face.”
This is why I don’t view the medication in isolation. The outcome is shaped just as much by the daily habits that support your body while you’re on it.
Where working with a dietitian comes in
In my practice, I work with clients using a non-diet, weight-inclusive approach that focuses on long-term health behaviors rather than restriction or quick fixes. My goal is to help you support your body in a way that is sustainable, realistic, and aligned with your life.
For clients on GLP-1 medications, I focus on making sure you’re getting enough protein and overall nutrition, building meal structure that supports consistent intake, and helping you stay connected to hunger and fullness cues in a way that doesn’t lead to chronic under-fueling. I also help troubleshoot common side effects, adjust nutrition strategies based on tolerance and lifestyle, and support you in maintaining muscle mass and energy.
Whether you’re using a GLP-1 for weight, insulin resistance, cholesterol, prediabetes, or conditions like PCOS, the goal is the same = to protect your metabolism, preserve lean muscle, and help you feel better in your body—not just see a lower number on the scale.
