The Claim

Whey protein intake results in prolonged suppression of ghrelin levels compared to simple carbohydrate intake in women with polycystic ovary syndrome, with ghrelin levels rising after 2 hours following carbohydrate consumption and remaining suppressed for up to 5 hours following whey protein consumption.

In plain English

In women with polycystic ovary syndrome, consuming whey protein keeps ghrelin levels lower for up to five hours, while consuming simple carbohydrates causes ghrelin levels to rise after two hours.

See the scientific wording

Whey protein suppresses the hunger hormone ghrelin for a longer duration than simple carbohydrates in women with polycystic ovary syndrome, with ghrelin levels rising after 2 hours following carbohydrate intake but remaining suppressed for up to 5 hours after whey protein intake.

Why this might work

Whey protein triggers the pancreas to release both insulin and glucagon at the same time. Insulin lowers blood sugar, but glucagon prevents it from dropping too low. This stable blood sugar keeps the stomach from releasing the hunger hormone ghrelin for up to five hours. Simple carbohydrates cause a quick spike in blood sugar and insulin, followed by a sharp drop. That drop tricks the brain into thinking the body is starving, so it releases ghrelin to make you hungry again after just two hours.

  1. Study: Reactive Hypoglycemia: A Trigger for Nutrient-Induced Endocrine and Metabolic Responses in Polycystic Ovary Syndrome

    In women with PCOS, eating a whey protein snack keeps hunger away for up to 5 hours, while a sugary snack makes hunger come back after just 2 hours. So protein helps you feel full longer than sugar.
