The Study
Reactive Hypoglycemia: A Trigger for Nutrient-Induced Endocrine and Metabolic Responses in Polycystic Ovary Syndrome
This study tested two types of snacks on a small group of women with PCOS and saw that one snack (protein) helped them lose more weight than the other (sugar). It also noticed that sugar sometimes made them feel shaky and triggered stress hormones. But it didn't prove sugar causes weight gain—it just showed a pattern in this small group.
Analysis score
Maximum 90 for a randomized controlled trial.
Where the score came from
Some women with PCOS get really hungry and shaky after eating sugary foods because their blood sugar drops too low. This makes them snack more and gain weight. Protein doesn’t cause that crash and keeps them full longer.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — losing 3.3 kg vs.
- 21.1 kg in 2 months is a meaningful difference for someone trying to manage PCOS and weight.
- 3Women who swapped a sugary snack for a whey protein snack lost 3.3 kg weight and 3.1 kg fat vs.
- 41.1 kg weight and 0.5 kg fat in 2 months.
- 5Ghrelin (hunger hormone) stayed down for 5 hours after protein but rose after 2 hours with sugar.

In obese women with polycystic ovary syndrome, eating simple carbohydrates causes a drop in blood sugar in about one-third of them, which leads to higher cortisol and adrenal androgen levels, increased hunger after three hours, and more snacking, resulting in continued weight gain.
In obese women with polycystic ovary syndrome, swapping a 240 kcal daily simple carbohydrate supplement for a whey protein supplement for two months leads to greater reductions in body weight and fat mass compared to continuing the carbohydrate supplement, even when total calorie intake is held constant.
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.
Eating carbohydrates that digest quickly leads to a sharp rise in blood sugar, followed by a drop below normal levels and an increase in hunger.
Among obese women with polycystic ovary syndrome, those who develop low blood sugar after eating carbohydrates have higher body mass index, higher leptin levels, higher insulin resistance, and lower sex hormone-binding globulin levels than those who do not develop low blood sugar after eating carbohydrates.
