Summary

This study looked at how liquid versus semi-solid meals influence appetite and calorie intake in 20 healthy adults. Participants ate either a liquid meal or oatmeal with the same calories and nutrients, then later ate as much lunch as they wanted. Researchers measured how full people felt, how fast their stomach emptied, and how many calories they ate at the next meal. The goal is to understand if food texture plays a role in controlling appetite and energy balance.
