• Conditions: Obesity and Overweight

• Registration Number: NCT06911073
• Lead Sponsor: ResBiotic Nutrition, Inc.

Brief Summary

This study aims to evaluate the impact of a specific oral postbiotic supplement on metabolic health in overweight adults.

Detailed Description

Obesity poses substantial health challenges contributing significantly to chronic metabolic disorders such as type 2 diabetes mellitus, cardiovascular disease, and diminished quality of life for people worldwide. Central to obesity-related metabolic dysfunction is dysregulation of appetite control, glucose homeostasis, insulin sensitivity, and systemic inflammation. Evidence indicates a strong connection between these metabolic disturbances and alterations in the gut microbiome, implicating microbiota dysbiosis as a potential target for intervention. Microbiome-based interventions underscore a promising approach in weight management and metabolic health.

Primary Outcome Measures

Name	Time	Method
To determine the effect of resM™ on weight	8 weeks	Change from baseline in weight (lb)
To determine the effect of resM™ on BMI	8 weeks	Change from baseline in BMI. Weight and height will be combined to report BMI in kg/m\^2)
To determine the effect of resM™ on food cravings	8 weeks	Change in reported food cravings from baseline based on Food Craving Questionnaire Trait-reduced (FCQ-T-r) scores. The total score reflects the severity of food cravings where 90 indicates the most severe and 15 indicates the least severe.
