Brief Summary

The goal of this clinical trial is to learn whether adding yoga exercise to a behavioral weight loss intervention improves weight loss in adults with overweight or obesity. It will also provide information about whether this approach to weight loss has additional benefits on other health and fitness measurements. The main questions it aims to answer are:

  • Is there a difference in weight loss between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in how much physical activity is completed between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in body composition (fat mass, lean body mass) between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in cardiorespiratory fitness the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in muscle strength between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in resting blood pressure between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in food intake or eating behaviors between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in feelings of stress or mood between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in sleep between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise?
  • Is there a difference in the change in mindfulness between the behavioral program that includes aerobic exercise plus yoga compared to the behavioral program that includes only aerobic exercise? Participants will:
  • Participate in a weight loss program for a period of 12 months that involves attending behavioral weight loss sessions. This involves coming to a session at the research center weekly for the initial 6 months and then every other week for the remaining 6 months.
  • Attempt to reduce the amount of food that they eat to reduce the calories they consume.
  • Participate in a combination of aerobic exercise plus yoga or just aerobic exercise.
  • Keep a record of the food they consume, use a digital scale provided to them, and wear an activity tracker provided to them for the period of 12 months.
  • Visit the clinical before starting the weight loss program, after 3 months, 6 months, 9 months, and 12 months to complete measurements of their weight and other measurements to monitor their progress.
  • Complete exercise sessions in the clinic between weeks 2-6, at month 6, and at month 12 to provide information about how they response to a single session of exercise.

Study Arms (2)

Behavioral Weight Loss Plus Aerobic Physical Activity

EXPERIMENTAL

The intervention is a 12-month behavioral intervention focused on modifying eating behaviors and physical activity. Participants will be provided weekly group-based behavioral session for months 1-6, with these sessions being offered twice per month during months 7-12. Participants will be instructed to self-monitor their weight, eating behaviors, and physical activity. A reduced energy diet ranging from 1200-2100 kilocalories per day will be recommended for participants. Physical activity will be recommended in the form of aerobic types of activity such as brisk walking and will progress from an initial amount of 100 minutes per week to 300 minutes per week across the initial 6 months of the intervention, with this level of physical activity continuing to be recommended between months 7-12.

A reduced energy diet ranging from 1200-2100 kilocalories per day will be recommended for participants. Physical activity will be recommended in the form of aerobic types of activity such as brisk walking combined with yoga. Aerobic activity will progress from an initial amount of 60 minutes per week to 180 minutes per week across the initial 6 months of the intervention, with this level continuing to be recommended between months 7-12. Yoga will progress from 40 minutes per week to 120 minutes per week across the initial 6 months of the intervention, with this level continuing to be recommended between months 7-12.
