The goal of this clinical trial is to investigate the safety and efficacy of MB-1 on metabolic health in overweight and obese adults. The main question it aims to answer is:

What is the difference in change in body weight from baseline at Day 84 between MB-1 and placebo?

Participants will be provided MB-1 or placebo and be assessed for anthropometric measurements, blood pressure, heart rate, and asked to complete appetite and satiety questionnaires and undergo a DEXA scan.
