GLP-1 medications like Ozempic, Wegovy, and Mounjaro are everywhere — but almost no one is talking about how they work differently in the context of perimenopause and menopause. In this solo episode, Karen Martel breaks down everything midlife women need to know about GLP-1 therapy: why it is not a replacement for HRT, how to protect muscle while using these medications, what microdosing actually means, and how to think about long-term metabolic health rather than just a number on a scale.

Every week there seems to be a new headline about GLP-1 medications. Someone in your feed swears they changed her life. Someone else insists they are dangerous and you should never touch them. Most of those conversations are happening in a vacuum — without any consideration of what is actually going on hormonally for women in midlife.

That is the conversation I want to have today.

If you are in perimenopause or menopause, your metabolic landscape is fundamentally different from what it was in your thirties. Estrogen is shifting or declining. You are losing muscle more easily than you used to. Insulin sensitivity may be changing. Sleep is disrupted, which affects cortisol and hunger hormones. Belly fat appears where it never did before. And the advice to simply eat less and move more is not adequate — not because willpower does not matter, but because the biology driving midlife weight gain is more complex than that.

GLP-1 medications — semaglutide, tirzepatide, retatrutide — work on pathways that go well beyond appetite. They affect insulin, glucagon, gastric emptying, inflammation, and even brain signaling around reward and satiety. That is why so many women feel they finally have traction on weight that would not budge despite doing everything right. But these medications also come with real considerations, especially around muscle loss, and especially in midlife.

This episode is my attempt to give you the most accurate, nuanced picture I can — without hype in either direction.

In This Episode, We Discuss

• Why menopause changes fat distribution and increases abdominal fat for many women
• How declining estrogen, muscle loss, disrupted sleep, and shifting insulin sensitivity affect midlife weight
• How GLP-1 medications work beyond simple appetite suppression
• Why using a GLP-1 is not cheating — and why that framing is unhelpful
• Why GLP-1 therapy does not replace hormone replacement therapy
• Whether HRT and GLP-1s can be used together
• Why muscle loss is one of the most significant risks with GLP-1 use in midlife
• Why protein intake and resistance training are non-negotiable on these medications
• Why having no appetite does not mean your dose is calibrated correctly
• Microdosing versus standard GLP-1 dosing and why slower is often better
• What a realistic and sustainable rate of fat loss looks like
• The role of thyroid optimization and hormone balance when weight loss stalls
• Why your maintenance plan needs to be part of the strategy from the very beginning

Frequently Asked Questions

Do GLP-1 medications work differently during perimenopause and menopause?

GLP-1 medications act on the same physiological pathways regardless of where a woman is hormonally, but the context of menopause matters significantly. Declining estrogen affects insulin sensitivity, fat distribution, muscle mass, sleep quality, and the body's overall metabolic rate. Because of these changes, midlife women may experience a greater risk of muscle loss on GLP-1s, may have underlying thyroid or hormonal issues that interfere with results, and may need additional support — including HRT — that a woman in her twenties would not. The medication is one layer of a more complex picture.

Should I do HRT before starting a GLP-1?

For many women, getting hormones optimized first — or at minimum evaluated — before adding a GLP-1 makes sense. Estrogen and progesterone influence metabolic health, sleep, cortisol, insulin sensitivity, and muscle retention. Starting HRT before or alongside a GLP-1 may make the medication work more effectively and may reduce some of the risks around muscle loss. That said, individual circumstances vary. A conversation with a clinician who understands both hormones and GLP-1 therapy is the most important first step.

Can I use HRT and a GLP-1 at the same time?

Yes. HRT and GLP-1 medications are not mutually exclusive, and for many women in perimenopause and menopause, using both together may offer complementary benefits. HRT addresses the hormonal root causes of many menopause symptoms and supports muscle and bone health. GLP-1 medications help regulate appetite, insulin, and body-weight set point. They work through different mechanisms and are generally considered compatible. Always work with a clinician who can monitor both.

How much protein do I need while taking a GLP-1 medication?

Protein needs increase significantly when you are in a calorie deficit, and GLP-1 medications can reduce appetite enough that many women are not eating nearly enough protein. Most practitioners working in this space recommend a minimum of 100 grams of protein per day, and many suggest 1.2 to 1.6 grams per kilogram of body weight or more when muscle preservation is the priority. Prioritizing protein at every meal — especially when total food intake is low — is one of the most important things you can do to protect muscle while losing fat.

What is microdosing and is it better than standard GLP-1 dosing?

Microdosing refers to using GLP-1 medications at doses lower than those used in major clinical trials — often starting very low and increasing slowly based on individual response rather than following a standard escalation schedule. Some practitioners and patients find this approach produces fewer side effects, better tolerability, and easier long-term adherence. It may also allow for more consistent protein intake because appetite is not suppressed as dramatically. However, the clinical evidence specifically comparing microdosing protocols to standard protocols is limited, and individual response varies considerably.

Why am I not losing weight even though I am taking a GLP-1?

Several factors can interfere with weight-loss results on GLP-1 medications. Undertreated hypothyroidism is one of the most common and underappreciated causes of a stall. Suboptimal estrogen or progesterone, high cortisol from chronic stress or poor sleep, insufficient protein intake, inadequate resistance training, or a dose that is not well-matched to your individual needs can all play a role. A stall is worth investigating rather than simply increasing the dose.

What happens when I stop taking a GLP-1?

Weight regain after stopping GLP-1 medications is well-documented and reflects the fact that these drugs address a regulatory issue in the brain and body — not a willpower deficit. When the medication is removed, the signals that were helping to reduce appetite and lower the body's defended weight set point are also removed. This is why having a maintenance strategy in place from the beginning matters. For some women, a long-term low maintenance dose may be appropriate. For others, the combination of optimized hormones, consistent resistance training, adequate protein, and improved metabolic health developed during treatment may help sustain results. This is an individual conversation.

Is taking a GLP-1 medication cheating?

No. Using a medication that corrects a physiological dysregulation is not cheating any more than using thyroid medication or HRT is cheating. For many women, GLP-1 medications address real biological barriers to weight loss — including impaired satiety signaling, insulin resistance, and elevated body-weight set point — that cannot simply be overcome through restriction and willpower alone. The more useful question is whether the medication is being used thoughtfully, with appropriate support for muscle preservation, nutrition, and long-term health.
