Satiation Clinical Trial
Official title:
The Lunch Study: the Combined Effects of Food Texture and Energy Density on Intake
Meal size is strongly influenced by a number of external features of the food environment
which can promote over-consumption, such as the availability of palatable energy dense
foods. The current research aimed to investigate whether natural food-based differences in
texture could be used to slow down eating rate and reduce intake from large portions and
higher energy dense foods.
A four-session randomised crossover study assessed the effect of faster vs. slower eating
rate, achieved through manipulating food texture, on ad-libitum consumption (weight and
calories) at a meal, alone and in combination with variations in meal energy-density (higher
vs. lower)

Primary | Ad libitum intake of the test meals - weight (g) | The weight of the test meal consumed during the test session was measured. There are four test sessions and participants eat one of the four test meals each session. The amount consumed was measured each time. |
Measured once for up to 20 minutes | No |
Primary | Ad libitum intake of the test meals - calories (kcal) | The weight of the meal consumed was measured and convert to calories using the meal energy density (which is known). There are four test sessions and participants eat one of the four test meals each session. The amount consumed was measured each time. |
Measured once for up to 20 minutes | No |
Secondary | Eating rate of the test meals | Video recordings of the participants eating are coded and from this eating rate was calculated as grams consumed per minute (g/min). | Measured once for up to 20 minutes | No |
Secondary | Changes in rated appetite pre- to post meal consumption and up to 90 minutes post-consumption | 100-point Visual Analogue Scale (VAS) ratings of hunger, fullness, desire to eat, prospective consumption and thirst | pre-meal, immediately post-meal, +15 minutes, +30 minutes, +45 minutes, +60 minutes, +75 minutes, + 90 minutes | No |
Secondary | Energy intake (kcal) for the rest of the test day recorded in a Food diary | Food intake recorded in a food diary | Up to 24 hours | No |
