Overview- In this study, overweight or obese, sedentary participants (age=35-55 years, n=20) will be randomized to a 12-week control period or an aerobic exercise intervention. Those randomized into the control group will then complete the exercise intervention subsequently. The planned energy expenditure per week of exercise will be 10-12 kilocalories per kilogram of body weight per week. Participants will complete three non-consecutive exercise sessions per week. Body weight, resting metabolic rate via indirect calorimetry, peak oxygen consumption (VO2peak) through graded exercise testing, fasting blood samples, CGM, sleep and dietary habits via self-report, and physical activity monitoring will be completed at prior to and following the aerobic exercise intervention.
