Acute Effects of SATIOSTAT Ingestion on Satiation Hormones, Gastric Emptying, Subjective Feelings of Appetite and Energy Intake
Study Details
Study Description
Brief Summary
SATIOSTAT is a composition comprising a specific dietary fibre component (a mixture of hydrocolloids with excellent safety profiles and a long history of use in humans) and a lipid component (long-chain fatty acids). The goal of this combination is to achieve long-acting delivery of long-chain fatty acids to the intestinal lining, triggering the sustained release of satiety-signals from intestinal cells, and consequently reducing appetite and lowering food intake in humans.
Effects of acute ingestion of SATIOSTAT vs. a control will be examined. On a first and second study day, volunteers receive a preload of either SATIOSTAT or a control and then an oral glucose load of 75g enriched with C13 sodium acetate. Gastric emptying will be measured by means of a breath test, and insulin, glucose and satiation hormones will be assessed. On the third and fourth study day, volunteers receive a preload of either SATIOSTAT or a control and are then presented a test meal. Total calorie intake is measured as well as subjective feelings of satiation. In addition satiation hormones are measured.

measured by commercially available ELISA (enzyme-linked immunosorbent assay )-kits
Secondary Outcome Measures
- Acute effects of SATIOSTAT on glucose tolerance measured by oral glucose tolerance test [changes from baseline to three hours after treatment]
measured with oral glucose tolerance test
- Acute effects of SATIOSTAT on gastric emptying measured by 13C-sodium-acetate breath test [changes from baseline to four hours after treatment]
measured by 13C-sodium-acetate breath test
- Acute effects of SATIOSTAT on subjective feelings of hunger and satiety measured by visual analogue scales [changes from baseline to three hours after treatment]
measured by visual analogue scales
- Acute effects of SATIOSTAT on subsequent calorie intake measured by calorie intake from a test meal [changes from baseline to two hours after treatment]
calorie intake from a test meal will be assessed
