Episode notes

The eating window gets positioned as a weight loss tool. It isn't. For women in perimenopause, the mechanism that makes meal timing powerful has nothing to do with calories or fat burning — and everything to do with your circadian clock, your liver's overnight hormone clearance, and your adrenal rhythm.

In this episode, functional nutritionist Miriam breaks down why the eating window works — and why it backfires for so many women in perimenopause when it's positioned as a fasting protocol rather than a circadian tool.

You'll learn what your liver, adrenal glands, and gut are actually doing during the overnight fasting window — and why eating late doesn't just disrupt sleep, it disrupts estrogen clearance, cortisol regulation, and gut repair at the cellular level.

Plus: how the optimal eating window looks completely different across the four gut-hormone patterns — and why a 16-hour fast that helps one woman will actively worsen another.
