Study Overview
Brief Summary
The primary aim of this work is, to 'relate psychological and behavioural parameters of hunger/satiety and food preference to gut hormones, neural activation and energy metabolism by dietary manipulation, across the human lifespan'.
Detailed Description
The Full4Health project aims to further understanding of the mechanisms of hunger and satiety. The proposal integrates investigation of human volunteers and laboratory rodents throughout the life course, applying imaging and other cutting edge technologies to critical research questions. Full4Health will combine study of the mechanisms of hunger and satiety with intervention studies to validate the effects of the relevant food characteristics on the regulation of satiety/hunger. The development of cerebral responses to food through the gut-brain axis across lifespan particularly during childhood, adolescence and elderly will be studied.

Arms & Interventions
Phase 1: Breakfast Study
Intervention: Breakfast Study (Other)
Phase 2: fMRI Study
Intervention: fMRI Study (Other)
Outcomes
Primary Outcomes
Changes in concentrations of biomarkers of appetite in response to each milk-based beverage
Time Frame: During each of the four 'Breakfast Study' visits blood will be taken at baseline, and 30, 60, and 120 minutes after consuming the milk-based beverage. Each visit will be seperated by one week.
The following blood-borne biomarkers of appetite will be measured: * Glucose * Total cholesterol * Triglycerides * Low density lipoprotein * High density lipoprotein * Insulin * Ghrelin (active) * Glucagon-like peptide-1 (active) * Peptide YY (total) * Leptin
Secondary Outcomes
- Neural responses to images of food when fasted and after consuming a milk-based beverage(There will be one week between both conditions (fasted and fed))
