The Claim

Elevated leptin levels mediate 51.75% of the protective effect of gluteofemoral adipose tissue on the risk of polycystic ovary syndrome, indicating that leptin's regulation of energy balance and reproductive hormones constitutes a key biological pathway connecting fat distribution to polycystic ovary syndrome.

How it works
1 study reviewed
In plain English

Higher levels of the hormone leptin explain about half of why fat stored around the hips and thighs is linked to a lower risk of polycystic ovary syndrome, as leptin influences how the body manages energy and reproductive hormones.

See the scientific wording

Elevated leptin levels mediate 51.75% of the protective effect of gluteofemoral adipose tissue on polycystic ovary syndrome risk, suggesting that leptin’s role in regulating energy balance and reproductive hormones is a key biological pathway linking fat distribution to PCOS.

What the research says

  1. Study: Beyond BMI: A Mendelian Randomization Study of the Causal Effects and Mediating Pathways of Regional Adipose Tissue Depots on Polycystic Ovary Syndrome

    This study found that having more fat around the hips and thighs lowers the risk of PCOS, and about half of that protection comes from a hormone called leptin, which helps regulate energy and hormones. So yes, leptin is a big part of why this type of fat is protective.
