About this study

Official title: Holistic Approach to Cardiometabolic Health and Obesity: Incretin-based Therapies, Nutrition, and Active Lifestyle

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • InterventionBehavioural

    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 TreatmentDrug

    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.

Questions about this trial

What is this clinical trial studying?

A study testing Intervention and Incretin-Based Treatment in people with Obesity & Overweight and Cardiometabolic Conditions, run by Laval University at 2 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 16 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Elisa Marin-Couture, Kin, PhD (1-418-656-8711 ext. 6103, elisa.marin-couture.1@ulaval.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in muscle mass (bioimpedance scale) (time frame: Baseline to 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jul 2026.
