Acute Effects of SATIOSTAT Ingestion on Satiation Hormones, Gastric Emptying, Subjective Feelings of Appetite and Energy Intake

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.

Description

Inclusion Criteria:

• Otherwise healthy
• Informed Consent as documented by signature (Appendix Informed Consent Form)

Exclusion Criteria:

• Food allergies, food intolerance
• Evidence of relevant cardiovascular, pulmonary, renal, hepatic, pancreatic, gastrointestinal, metabolic, endocrinological, neurological, psychiatric or other diseases at screening
• Chronic or clinically relevant acute infections
• Clinically relevant abnormalities in chemical, haematological or any other laboratory parameters
