Intermittent Fasting in Midlife: Yes, No, or Maybe?

Skipping breakfast isn't a personality. It's a tool — and not always the right one.

The quick explanation

IF can improve insulin sensitivity, but extended fasts can spike cortisol and impair sleep in perimenopausal women. Most do better with a 12-hour overnight fast and protein-forward breakfast.

Why this matters

Generic IF advice was studied mostly in men. Midlife women need a gentler version.
