Can cooking classes curb dangerous pregnancy weight gain?
NCT ID NCT07828743
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Women with class III obesity who gain too much weight during pregnancy face higher risks of diabetes, high blood pressure, cesarean delivery, and larger babies. Standard prenatal care often does not include nutrition counseling based on weight. This trial tests whether adding group nutrition classes with cooking demonstrations helps these women gain less weight during pregnancy compared to standard care alone. Researchers will measure weight gain from the first prenatal visit to delivery and check blood sugar levels.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- group nutrition education classes with cooking demonstrations
- What this could lead to
- If it works, this could give pregnant women with severe obesity a low-cost way to manage weight gain and lower their risk of diabetes, high blood pressure, and cesarean delivery.
- What could go wrong
- Nutrition classes may not change eating habits enough to affect weight gain, and the trial is small. Results may not apply to women with different circumstances or those who receive care elsewhere.
