Effects of weight loss with and without exercise on metabolic health

Official title: Metabolic Adaptations to Weight Loss With and Without Exercise

Run by University of Michigan · NCT05806801 · Data updated 2026-11-12

This study is testing whether losing weight with exercise helps improve metabolic health more than just losing weight through dieting alone for people with obesity.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-40 with a BMI between 30-40 kg/m2 who are weight stable and do not engage in regular exercise.

Probably not a fit

Patients with cardiovascular disease, diabetes, or other metabolic diseases, as well as those on medications affecting metabolism, may not benefit from this study.

What this trial studies

This study investigates how combining caloric restriction with exercise influences metabolic health in individuals with obesity. It aims to understand the mechanisms behind the health benefits of exercise during weight loss, particularly focusing on changes in abdominal fat tissue. Participants will be assigned to either a moderate-intensity continuous training exercise group or a control group with no exercise, allowing researchers to compare the effects of these interventions on metabolic adaptations. The findings could lead to more effective lifestyle interventions for obesity-related disorders.

Why it matters

Potential benefit: If successful, this study could provide insights that enhance the effectiveness of weight loss programs and improve metabolic health outcomes for patients with obesity.

How similar studies have gone: Other studies have shown that combining exercise with caloric restriction can lead to improved metabolic outcomes, suggesting this approach is promising.
