Lifestyle Changes, Mushroom Supplementation, and Bupropion to Reduce Adiposity and Cardiometabolic Risk

Not Yet RecruitingPhase 3

Sponsor: Uppsala University

Conditions: Cardiometabolic Syndrome, Obesity and Cardiovascular Risk, Overweight , Obesity

Interventions: Bupropion 150 mg, Lyophilized powder from edible mushrooms, Lifestyle Management

Countries: Sweden

The increasing prevalence of obesity, its serious health consequences, and the substantial economic burden on healthcare systems underscore a pressing need for effective, long-term prevention strategies that can be implemented in primary care. Emerging evidence suggests that combining lifestyle modification with dietary supplements and pharmacological treatment may enhance and prolong intervention effects, yet comparative long-term data on their individual and combined efficacy are limited. Therefore, this study aims to evaluate the independent and additional effects of a comprehensive lifestyle intervention, a mushroom-based dietary supplement, and bupropion treatment over 12 months, to identify more effective and sustainable strategies for obesity prevention in overweight and obese adults.
