Официальное название
Probiotic Regulation of Food Intake Through Satiety Stimulation and Gut Microbiota Modulation
Обзор
The goal of this 16-week randomised, placebo-controlled parallel study is to investigate the effect of a newly formed probiotic supplement on satiety and gut microbiota composition in healthy men and women with overweight or obesity form 20-70 years old. The main question it aims to answer is: Does the probiotic supplement increase feelings of satiety and alter gut microbiota composition? Participants will: * Receive a daily dose of 6 g probiotic supplement (packed in sachets of 3 g) or placebo for 16 weeks. * Visit the research unit 3 times at baseline, week 8 and week 16 of the intervention for blood draws and delivering fecal samples. * Keep a study diary to report deviations from their daily habits and fill in food questionnaires.
Подробное описание
Rationale: Satiety hormones, including glucagon-like peptide-1 (GLP-1), are key regulators of food intake. Deficiencies in the release of satiety hormones as well as alterations in the composition and the function of the gut microbiota are hallmarks of overweight and obesity. Probiotics can improve the overall structure of the gut microbiota, and show strain-specific differences with regard to their ability to stimulate satiety hormones. Those animal-based findings, if confirmed in human studies, may pose a gateway for decreased food intake, weight management, and ultimately weight loss. The investigators hypothesise that a newly developed combination of probiotic strains, specifically selected for their potential to (in vitro) influence pathways related to weight management, will decrease food intake through increased release of satiety hormones (i.e. GLP-1) and beneficial alteration of the gut microbiota in humans.
Objective: The primary objective of the study is to investigate the effects of a combination of specifically selected probiotic strains in a new probiotic formulation on ad libitum food intake, in individuals with overweight and/or obesity. The investigators will address this objective firstly with an acute study followed by a proof-of-concept 4-months intervention study comparing a total of 98 individuals in a 16-week randomised, placebo-controlled parallel study (49 participants probiotic/ 49 participants placebo).
Study design: This intervention study will have a randomised, controlled parallel design. The total study duration will be 16 weeks.
Study population: A total of 98 men and women between the ages of 20-70 years old, with overweight/obesity (BMI: 26-40 kg/m2) will be recruited, accounting for a drop-out rate of 20%.
Intervention: Study participants will receive a daily dose of 6 g probiotic supplement (packed in sachets of 3 g) or placebo for 16 weeks.
Main study parameters/endpoints: At baseline and after 16 weeks, participants will visit the research facilities for assessments. The primary endpoint is the difference in satiety measured by ad libitum food intake comparing the probiotic and control intervention. Secondary outcome parameters are related to changes in satiety hormones (including GLP-1), fecal microbiota analysis, insulin sensitivity (HOMA-IR), inflammatory markers and lipid metabolism.
Exploratory outcomes concern perceived satiety, body composition and mental health. This study will provide insight into the potential beneficial effect of a newly composed probiotic supplement on satiety in overweight/obese adults.
