Read time: 6 minutes

If you’re a woman in your 40s feeling drained, foggy, or like your body just isn’t keeping up anymore — you’re not alone. Perimenopause fatigue is real, but it’s often misunderstood (and misdiagnosed). The good news? You can boost your energy naturally by working with your changing hormones, not against them.

You’re Not Lazy — You’re in Perimenopause

One of my clients — a powerhouse CEO and mom of two — told me she was in bed by 8:30 every night.

Not because she wanted to.
Because she had to.

She was barely making it through the workday. Her brain felt heavy. Her motivation was gone. And no matter how much sleep she got, she still woke up tired.

Her question to me was simple:

“Is this just aging?”

The answer? Absolutely not.

Why Perimenopause Causes Fatigue in Women Over 40

If you’re noticing these symptoms:

  • 😴 Afternoon crashes that wipe you out

  • 😵‍💫 Brain fog and memory slips

  • 🍫 Sugar cravings like clockwork

  • 😡 Mood swings that don’t feel like “you”

…it’s not a personal failing. It’s a full-body hormonal recalibration.

Here’s what’s happening inside:

  • Estrogen & progesterone fluctuations disrupt your natural energy rhythm.

  • Mitochondria (your cells’ power plants) slow down production.

  • Cortisol spikes from stress & poor sleep drain your reserves.

  • Blood sugar instability makes your energy rollercoaster.

And yet, most women are told to:
“Get more sleep.”
“Cut calories.”
“Exercise more.”

❌ That advice doesn’t work — and can make things worse.

How to Boost Your Energy Naturally in Perimenopause

Here’s what I teach my clients and inside my programs — science-backed strategies for women 40+ that actually work:

1. Start the Day With 25–30g of Protein

Stabilizes blood sugar, reduces cortisol spikes, and sets the tone for steady energy.

2. Swap HIIT Marathons for Strength + Walking

Build muscle to support metabolism, and use brisk walking to regulate hormones.

3. Calm Your Nervous System Daily

Breathwork, journaling, stretching, or meditation — even 10 minutes helps regulate cortisol and prevent energy crashes.

4. Eat in Rhythm With Your Body

Skipping meals or eating late at night disrupts hormonal balance and deep sleep.

5. Prioritize Strength Training Over Endless Cardio

2–3 focused sessions a week preserve lean tissue and keep metabolism humming.
