The Claim
Ovariectomy in female mice partially reverses weight gain and fat accumulation induced by a ketogenic diet but does not restore glucose tolerance, indicating that estrogen suppression contributes to fat loss under ketogenic conditions without fully resolving insulin resistance.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In female mice, removing the ovaries reduces weight and fat gained from a ketogenic diet but does not improve blood sugar control, showing that estrogen influences fat storage but is not the only factor affecting insulin resistance during ketosis.
See the scientific wording
In female mice, ovariectomy partially reverses ketogenic diet-induced weight gain and fat accumulation, but does not restore glucose tolerance, suggesting that estrogen suppresses fat loss but is not the sole determinant of insulin resistance under ketogenic conditions.
When estrogen is removed, the body increases a hormone called FGF21 in brown fat, which turns up heat production and burns more fat for energy. This causes weight and fat loss. But even with more fat burning, the body still cannot process sugar properly because something else — not related to estrogen or FGF21 — keeps the insulin system broken.
What the research says

When scientists removed the ovaries from female mice on a keto diet, the mice lost weight and fat, but their blood sugar stayed high. This means estrogen makes mice store more fat, but something else causes their blood sugar problems—even without ovaries.
