What this study is about

The goal of this clinical trial is to evaluate whether combining a six-month structured lifestyle intervention (physical activity and nutrition) with incretin-based weight-loss medication improves preservation of muscle mass and physical function in adults living with obesity, compared with medication alone, and to assess the feasibility of a collaborative hospital-community care model. This one-year pilot study will recruit 120 adults aged 18-70 years with obesity (BMI ≥30 kg/m² or ≥27 kg/m² with at least one comorbidity) receiving routine obesity care at the Institut universitaire de cardiologie et de pneumologie de Québec - Université Laval. All participants will initiate physician-prescribed incretin-based therapy as part of standard care. The intervention group will receive medication plus a six-month structured lifestyle program delivered in collaboration with an exercise facility, including supervised strength-focused exercise and bi-monthly nutrition counseling, followed by a six-month consolidation phase. The control group will receive medication alone. Outcomes will be assessed at baseline and at 3, 6, and 12 months. Participants will be randomly assigned in a 1:1 ratio to either the medication-only group or the combined medication and lifestyle intervention group. Participants randomized in the medication only group will receive a personalized consult with both a registered dietician and kinesiologist at the end of the study.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Full registry criteria

Inclusion Criteria: * Adults aged 18 to 70 years * Prescribed, but not yet initiated, incretin-based pharmacotherapy \[e.g., GLP-1 receptor agonist or dual GIP/GLP1 agonist\] living with obesity, defined as: * BMI \>30 kg/m2, or * BMI \>27 kg/m2 with presence of comorbidities (e.g., type II diabetes, hypertension, hypercholesterolemia) Exclusion Criteria: * Medical contraindications to physical activity practice (e.g., unstable cardiovascular disease, severe orthopedic limitation) * Prior or ongoing incretin-based therapy or history of bariatric surgery * Pregnancy, current breastfeeding or planned pregnancy during the study period * Implemented medical devices (e.g. pacemaker, defibrillator) * Chronic conditions affecting protein metabolism or nutrition (e.g., advanced kidney disease, active cancer)

Treatments and study arms

Intervention

Behavioral

Participants in the intervention will receive standard incretin-based pharmacotherapy combined with an individualized lifestyle intervention. Supervised physical activity sessions, delivered by a registered kinesiologist, will focus primarily on resistance training and will be tailored to each participant's fitness level and medical status to support the preservation of skeletal muscle mass and physical function. In addition, participants will receive personalized nutritional counseling from a registered dietitian to optimize dietary quality, ensure adequate protein intake, and reduce the risk of nutritional deficiencies.

Incretin-Based Treatment

Drug

Participants assigned to the medication-only arm will receive standard medical care consisting of incretin-based pharmacotherapy prescribed and monitored by their treating physician, in accordance with usual clinical practice. No structured or supervised physical activity or nutritional intervention will be provided during the study period.

Primary outcomes
