Menopause and Insulin Resistance: Why It Sneaks Up on You

What… the Menopause?

Each week we spotlight an unexpected and frustrating symptom of menopause that no one warned you about. Because menopause is more than just hot flashes and missed periods.

This week’s spotlight: Insulin Resistance

What’s Going On?

What Is Insulin Resistance? 

Insulin resistance happens when your cells stop responding efficiently to insulin, which is the hormone that helps move glucose (sugar) from your bloodstream into your cells to make energy.

When your cells become less sensitive to insulin (aka insulin resistance), your body makes more of it to compensate. So over time, this can lead to higher blood sugar levels, stubborn weight gain, inflammation, fatigue, and eventually increase the risk of prediabetes and type 2 diabetes.

Basically, your body is working harder to do the same job..and something’s gotta give.

Why does this happen during menopause?

The short answer: declining estrogen changes how your body handles glucose.

Estrogen helps regulate insulin sensitivity, supports muscle mass, and influences where fat is stored. As estrogen declines during perimenopause and menopause, several things can happen:

• Your body becomes less efficient at using insulin
• You may lose lean muscle mass, which reduces glucose uptake
• Fat storage shifts more toward the abdominal area
• Cortisol and stress can hit harder
• Sleep disruption worsens blood sugar control

This creates the perfect storm for insulin resistance.

It’s not just about weight gain. It’s a metabolic shift.

Tune into this episode of my Hack My Age: Menopause Upgrade podcast, where I share why menopause isn’t simply a hormone issue, it’s a whole-body systems issue. Blood sugar regulation is often one of the first places women begin to notice that change.

You’re Not Alone: How Common Is Insulin Resistance in Menopause?

Insulin resistance over the age of 40 is far more common than most women realize.

Research shows that insulin sensitivity naturally declines with age, but the menopausal transition accelerates that process. Many women begin noticing changes in their 40s, often before they realize they are even in perimenopause.

Women with type 1 diabetes who have been wearing glucose monitors most of their lives report that they see they need to add more insulin as they go through the menopause transition. Also, those who take menopausal hormone therapy report they need less insulin. More details are in this podcast episode.

Signs can include:

• Belly fat that seems impossible to lose
• Energy crashes after eating
• Strong sugar or carb cravings
• Brain fog
• Poor sleep
• Increased hunger
• Higher fasting glucose on bloodwork
• Elevated triglycerides
• Feeling “puffy” or inflamed

Many women assume they need more willpower.

Often, they need better blood sugar support.

This is why so many women say: “I’m doing the same things I always did, and now nothing works.”

Because your metabolism changed.

What Can You Do? How to Improve Insulin Resistance During Menopause

In many cases insulin resistance can be reversed, especially when caught early.

The goal is not perfection. The goal is improving insulin sensitivity and reducing the constant blood sugar spikes that keep your body stuck in stress mode.

Here’s where to start:

1. Prioritize protein first. Start your meals with protein, not carbs. Protein helps stabilize blood sugar, improves satiety, and supports muscle mass, which becomes even more important after menopause.

Aim for a protein-rich breakfast instead of starting the day with toast, cereal, or fruit alone.

Think, eggs, greek yogurt, cottage cheese, fish, chicken, tofu, and protein smoothies. Your blood sugar will thank you.

2. Lift weights. Muscle is your metabolic Spanx.

Strength training improves insulin sensitivity because muscle helps absorb glucose more efficiently. It also helps protect against age-related muscle loss.

Walking is great. But resistance training is the upgrade. Even 2 sessions per week can make a real difference.

3. Watch the stress-cortisol connection. Chronic stress drives cortisol. High cortisol drives blood sugar dysregulation.

This is why “healthy eating” alone often doesn’t solve the problem. If your nervous system is constantly activated, your body behaves like it’s under threat.

Sleep, recovery, nervous system regulation, sunlight, and boundaries matter just as much as nutrition.

4. Build meals, not snacks. A coffee and a granola bar is not a meal.

Balanced meals with protein, fiber, healthy fats, and slow-digesting carbohydrates create steadier energy and fewer cravings later.

The more stable your blood sugar, the less your body demands emergency sugar fixes.

5. Test, don’t guess Ask for the following tests: 

• Fasting glucose
• Fasting insulin
• HbA1c
• Triglycerides
• Waist circumference trends

Sometimes “normal” labs still hide early dysfunction.

6. Supplements In addition to the healthy diet and lifestyle:

• Berberine*
• Inositol*
• Chromium*
• Cinnamon

7. Hormone Replacement Therapy (HRT) speak with your doctor:

• Body(bio-)-identical estradiol
• Body(bio)-identical progesterone
• Testosterone

What Worked for Me?

I consistently talk about menopause through the lens of metabolic health, not just symptom management. My approach focuses on:

• Building muscle through strength training
• Prioritizing protein and nutrient-dense meals
• Going to bed and waking at the same time
• Getting 7 to 8 hours quality sleep
• Spending every meal outdoors
• Practice breathwork and meditation daily
• I love to use the sauna
• Hormone therapy for menopause
• Test my blood sugar with a Continuous Glucose Monitor (CGM)*

I often remind listeners that women in midlife are not broken, they simply need a new strategy for a new hormonal landscape.

One of the biggest shifts? Realizing that less cardio and more strength, recovery, and blood sugar awareness often creates better long-term results.

FAQs: About Menopause and Insulin Resistance

Does menopause cause diabetes?

Menopause itself does not directly cause diabetes, but it increases the risk by reducing insulin sensitivity, increasing abdominal fat storage, and disrupting sleep and stress hormones. This makes blood sugar management more difficult during midlife.

Can HRT help insulin resistance?

Hormone replacement therapy (HRT) may improve insulin sensitivity for some women, especially when started at the right time and under medical supervision. It is not a standalone treatment, but it can be part of a bigger strategy.

Why am I gaining weight only around my stomach?

Declining estrogen changes where fat is stored. During menopause, fat tends to shift from the hips and thighs toward the abdominal area, which is more strongly linked to insulin resistance and metabolic risk.

Is fasting good for insulin resistance in menopause?

It depends. Some women do well with strategic fasting, while others find it increases cortisol, cravings, and energy crashes. The best approach depends on your stress levels, sleep quality, and overall metabolic health.

Can thin women have insulin resistance?Yes. Insulin resistance is not only about body size. You can be thin and still experience poor blood sugar regulation, especially if stress, sleep disruption, muscle loss, or hormonal changes are involved.
