The fasting trap nobody warns you about:

Skip breakfast → Stress hormones spike → Thyroid slows → Metabolism crashes → Weight gain → Restrict more → Repeat

The brutal cycle that’s destroying perimenopausal metabolisms.

Here’s what’s really happening: When you fast, cortisol skyrockets to maintain blood sugar (that’s its main job) Your thyroid gets the message “we’re in survival mode” and SLAMS the brakes on your metabolism.

The truth they’re not telling you: Your body will sacrifice your thyroid to keep your brain alive. Every. Single. Time.

At 49 myself and after 20 years of helping thousands of women reverse thyroid dysfunction, I’ve seen intermittent fasting destroy more metabolisms than any other “wellness” trend.

What actually works:
✔️Protein + carbs within 1 hour of waking
✔️NEVER workout fasted (your thyroid will thank 
you)
✔️Consistent meal timing (your thyroid loves routine)
✔️Managing stress BEFORE restricting food
✔️Testing beyond TSH (Free T3, T4, Reverse T3)

Your thyroid isn’t lazy - it’s protecting you from the stress you’re putting it under.

This is exactly why I’m breaking down the fasting-metabolism connection in my FREE masterclass Monday, Oct 14th at 9am PST/12pm EST.

You’ll discover:
✅ Why fasting backfires for perimenopausal women
✅ The cortisol-thyroid-insulin cascade keeping you stuck
✅ The 3 pillars that actually reverse insulin resistance
✅ How to eat to support (not sabotage) your metabolism
