Your body stores fat in different places — belly fat is bad for health, but hip and thigh fat might help. This study found that women with more fat around their hips and thighs are less likely to get PCOS, even if they’re the same weight as others.
Surprising Findings
Gluteofemoral fat reduces PCOS risk by 15.5% — not because it’s 'good fat,' but because it acts as a metabolic sink that pulls excess fatty acids away from organs.
Most people think all fat is bad or at least neutral — this shows a specific fat depot actively protects against a major hormonal disease.
Practical Takeaways
If you have PCOS or are at risk, focus on improving insulin sensitivity through low-glycemic foods, strength training, and sleep — not just weight loss.

Men and women tend to store body fat in different areas: men more around the abdomen, and women more around the hips and thighs.
In individuals with polycystic ovary syndrome, a specific type of body fat around the hips and thighs appears to lower risk primarily by improving how the body responds to insulin, with fasting insulin levels accounting for most of this protective effect.
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.
Increased levels of sex hormone-binding globulin, which is influenced by fat stored in the hips and thighs, reduce the amount of free testosterone in the body, and this mechanism accounts for about 25% of why this fat distribution is linked to a lower risk of polycystic ovary syndrome.
People with more fat around the abdomen compared to fat around the hips and thighs have a higher likelihood of developing polycystic ovary syndrome.
