The Claim

In non-obese women with polycystic ovary syndrome, higher dietary intake of total fat, saturated fatty acids, and monounsaturated fatty acids is associated with higher serum leptin concentrations, and higher dietary intake of total fat, monounsaturated fatty acids, polyunsaturated fatty acids, and long-chain polyunsaturated fatty acids is associated with lower serum ghrelin concentrations.

In plain English

In non-obese women with polycystic ovary syndrome, higher consumption of certain dietary fats is linked to higher levels of the hormone leptin and lower levels of the hormone ghrelin.

See the scientific wording

In non-obese women with polycystic ovary syndrome, higher dietary intake of total fat, saturated fatty acids, and monounsaturated fatty acids is associated with higher serum leptin concentrations, while higher intake of total fat, monounsaturated fatty acids, polyunsaturated fatty acids, and long-chain polyunsaturated fatty acids is associated with lower serum ghrelin concentrations, suggesting a link between dietary fat composition and appetite-regulating hormones in this population.

Why this might work

When more dietary fat is consumed, the body becomes less responsive to insulin, causing insulin levels to rise. Higher insulin signals fat cells to release more leptin, making the brain feel full, while also telling the stomach to produce less ghrelin, reducing hunger signals.

  1. Study: The Association of Serum Levels of Leptin and Ghrelin with the Dietary Fat Content in Non-Obese Women with Polycystic Ovary Syndrome

    In women with PCOS who aren't overweight, eating more healthy fats like those in olive oil and nuts was linked to higher levels of the 'I'm full' hormone (leptin) and lower levels of the 'I'm hungry' hormone (ghrelin), which could help control appetite.
