If you cut dietary fat to manage your weight in perimenopause, your hormones noticed.
Estrogen clearance requires bile. Bile production requires dietary fat. When fat drops, bile slows — and used estrogen stops clearing efficiently.
It recirculates instead.
That recirculating estrogen re-binds to estrogen-sensitive tissue. It amplifies the pattern: bloating, breast tenderness, weight that won’t shift, mood that tracks your cycle.
That’s a clearance problem — built directly into the low-fat approach women were told to follow.
The other piece: every steroid hormone your body produces — estrogen, progesterone, cortisol — is synthesized from cholesterol.
Dietary fat is not optional. It is the infrastructure.
If this explains something you’ve been living with without a clear answer — the quiz in my bio identifies your pattern and the specific gaps it creates.
