Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

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:

    • >30 kg/m2, or
    • BMI >27 kg/m2 with presence of comorbidities (e.g., type II diabetes, hypertension, hypercholesterolemia)

Exclusion criteria

Exclusion Criteria:

  • Medical 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)
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Placebo comparator
    Medication alone

    Participants will be randomly assigned to the incretin-based pharmacotherapy only.

    Drug: Incretin-Based Treatment

  • Experimental
    Incretin-based pharmacotherapy combined with a 6-month lifestyle intervention

    The intervention group will receive an incretin-based pharmacotherapy combined with a 6-month lifestyle intervention (weekly group exercise sessions, individual consultations with a kinesiologist and a registered dietitian every two months)

    Behavioral: Intervention

Interventions

  • BehavioralIntervention

    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.

  • DrugIncretin-Based Treatment

    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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2026 (actual). Primary completion is estimated for Mar 2028, 20 months after the start.

Of 3,680 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's planned 20 months is below that.

Counting every sponsor, half of 3,843 studies reached it within 22 months; a quarter within 10 and three quarters within 42.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
