Clinical Trial Summary

The purpose of this study is to investigate how gut hormones and brain areas respond differently to gastric distention, tasteless calories, or palatable food and how this alters appetite.

Related Conditions & MeSH terms

• Healthy

Intervention

Other:
• Functional Magnetic Resonance Imaging (pCASL-MRI)
MRI's will be performed at multiple points on each visit day.
• Intragastric Balloon
Intragastric Balloon will be placed during Visit 2 study day and inflated to maximum tolerated volume. Patient will then be scanned in the MRI.
• Elemental Meal
Patient will ingest the tasteless elemental meal until their maximum level of fullness. Once full, the patient will be scanned in the MRI.
• Hedonic Meal
Patient will ingest meal of their choice from a local food delivery service and eat until they reach their maximum level of fullness. Once full, the patient will be scanned in the MRI

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Difference in Cerebral Blood Flow related to hypothalamus	The mean difference in cerebral blood flow (CBF) at fullness (satiation) and return to hunger (satiety) to the hypothalamic area.	1 month
Secondary	Cerebral Bloodflow related in multiple brain areas	The mean difference in cerebral blood flow (CBF) at fullness (satiation) and return to hunger (satiety) to the other brain areas related to food intake regulation.	1 month
Secondary	Cerebral Blood Flow between three stimuli	The mean difference in cerebral blood flow (CBF) between the 3 different stimuli.	1 month
Secondary	Hormone level	Differences in hormones levels (ghrelin, GLP-1, CCK, PYY, leptin, insulin, GIP, amylin) at each of the stages (I.e., baseline, fullness, maximal fullness) after the three different stimulations. These hormones will be compared before and after the same stimulation days. The hormone measurements on stimulation days will also be compared to each other.	1 month
Secondary	comparison of calories	Correlation the caloric consumption to fullness, maximal fullness with degree of cerebral blood flow(CBF) change on PASL MRI.	1 month
Secondary	calorie corellation to hormones	Correlation the caloric consumption to fullness, maximal fullness with changes in the hormonal levels (ghrelin, GLP-1, CCK, PYY, leptin, insulin, GIP, amylin).	1 month
Secondary	hormone level comparison	Differences in the hormonal levels (ghrelin, GLP-1, CCK, PYY, leptin, insulin, GIP, amylin) between fullness and hunger after the three different stimulations. These hormones will be compared before and after the same stimulation days. The hormone measurements on stimulation days will also be compared to each other.	1 month
Secondary	Time differences in stimuli	Differences in time to next meal after maximal fullness after the three different stimulations.	1 month
Secondary	Caloric consumption differences in stimuli	Differences in the caloric consumption after maximal fullness after the three different stimulations.	1 month
Secondary	FitBit measured Physical Activity	Measurement of daily physical activity during free-living conditions measured through the use of FitBit tracker over the duration of the study.	1 month
