A glass of water gulped down while eating may cause weight gain? It made people eat more food

A Cornell and Penn State study of 86 adults found that drinking more water during meals was linked to eating more food.

For every 100g increase in water intake, participants ate about 39g more food, or roughly 49 kcal.

Researchers say the effect may be due to delayed sensory-specific satiety, meaning fullness cues arrive later.

The findings suggest that drinking water while eating could unintentionally increase meal size, relevant to weight management.
