Clinical Trial Summary

This study aims to investigate the effects of equicaloric texture modified and regular meals that are either fortified with protein or not on dietary intake and satiety in older adults (65+) living in the United Kingdom (UK).

Description:

- To investigate whether there are any differences in appetite responses following a texture modified meal compared to a standard meal. - To investigate whether protein-enriched versions of a texture modified meal and/or standard meal affects satiety and subsequent intake in healthy older adults. - To investigate the effects of a texture modified diet, standard diet and their protein-enriched versions on gastric emptying in healthy older adults.

Intervention

Behavioral:
• Preload meals that are solid or texture modified and are fortified with protein or not fortified with protein
Immediately after consuming the preload meal, volunteers will use a 100mm visual analogue scale (VAS) to rate their liking towards the meal, their hunger, fullness, desire to eat and prospective food intake. Subsequently, they will record these every 30 minutes until they consume their ad-libitum dinner

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Intake at ad-libitum dinner	Intake at the ad-libitum meal is measured (grams). Volunteers are instructed to eat only until they feel comfortable satisfied and are given 20 min to consume the meal.	4 days in total (one measurement per study day)
Secondary	Ratings (Appetite, hedonic and palatability) of breakfast, preload lunch and ad-libitum dinner	Appetite, hedonic and palatability ratings are assessed using validated 100 mm Visual Analogue Scales (VAS, sscale 0-100). Before and immediately after breakfast and assessed every 30 min for 360 min	Regular ratings each study visit, 4 days in total
Secondary	Gastric emptying	Gastric emptying will be measured using 13C-labelled sodium acetate which will be added into a bottle of water. This will be consumed alongside preload meal. Measurements will be taken every 1 hour after consumption of breakfast up to preload, then every 15 min after the preload for 180 min.	Regular samples each study visit, 4 days in total
