Changes in Body Composition Including Muscle With Anti-Obesity Medications, Both With and Without Exercise (M3-E)
The goal of this clinical trial is to learn whether adding either cardiovascular exercise or resistance exercise to pharmacotherapy treatment for obesity improves the retention of lean mass compared to pharmacotherapy alone in adults with overweight or obesity who are prescribed pharmacotherapy for obesity treatment by their personal physician. It will also provide information about whether either form of exercise added to pharmacotherapy for obesity treatment has additional benefits on other health and fitness measurements. The main questions it aims to answer are:
- Is there a difference in the change in total lean body mass between pharmacotherapy alone and either pharmacotherapy plus cardiovascular exercise or pharmacotherapy plus resistance exercise?
- Is there a difference in the change in muscle mass between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in muscle quality between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in body weight between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in body composition (fat mass, fat mass distribution) between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in cardiorespiratory fitness between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in muscle strength between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in physical function between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in bone mineral density between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in bone biomarkers between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in resting blood pressure between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in energy intake between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there a difference in the change in physical activity between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)?
- Is there an effect of sex, race/ethnicity, age, menopausal status, obesity management medication type, or other demographic characteristics on the outcomes that are being measured.
- What is the extent to which the retention of lean body mass or muscle mass mediates the effect of exercise on weight changes.
Participants will:
- Initiate and continue throughout the study period an eligible obesity management medication that is prescribed by their healthcare provider, and to report their adherence to this medication to the investigators.
- Participant in this study for a period of 6-8 months to complete outcome assessments that occur at baseline and at the conclusion of 6 months of the intervention period, and monitoring visits that occur at weeks 3, 6, 9, 12, 15, 18, and 21.
- If attend 3 supervised exercise sessions per week if assigned to either the cardiovascular exercise intervention or the resistance training intervention for a period of 24 weeks.

Experimental: Standard Care with an Obesity Management Medication
Participants will receive standard medical care from their personal physician related to their obesity management medication for a period of 6 months.
Progression of this medication will be monitored as part of the participation in this study.
Participants will undergo screening and baseline assessments prior to initiating the use of the medication and after a period of 6 months.
Upon randomization, participants will receive a "Nutrition 101" session where dietary considerations while taking this medication will be discussed.
We will also have a brief contact (weeks 3, 6, 9, 12, 15, 18, and 21) with the participant to monitor changes in weight, blood pressure, health status, and medication adherence and use (including the dose of the obesity management medication that they have been prescribed).
Participants will be instructed to maintain their current level of physical activity throughout the 6-month study period.
|
Participant will receive standard medical care that includes the prescription and titration of a study eligible obesity management medication.
Participant will receive brief nutrition counseling specific to obesity managment medications after randomization for this study.
|
|
Experimental: Standard Care with an Obesity Management Medication Plus Cardiovascular Exercise Training
Participants will receive the same standard of care as described for the "Standard Care with an Obesity Management Medication" condition; however, participants will also engage in supervised cardiovascular exercise training.
This will occur on 3 days per week and will progress to 50 minutes per session (150 minutes per week).
The intensity of the exercise will progress from 60%±5% to 70%±5% of age-predicted maximal heart rate (if taking beta-blocker medication intensity will progress from a Rating of Perceived Exertion of 11-13 to 12-14 based on the 6-20 Borg scale).
While walking will be the preferred mode of exercise, we will allow for alternative forms of cardiovascular exercise (upright or recumbent cycling, elliptical, etc.) to accommodate any physical limitations that may be present for a participant.
Heart rate will be monitored throughout these exercise sessions.
