What this study is about

The purpose of this study is to learn more about how common lifestyle interventions, such as exercise, affect how our brains respond to performing thinking tasks and to viewing pictures of foods and various other objects. The investigators are also interested in how changes in hormones that might be different in men and women could affect how lifestyle interventions change these brain responses.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Treatments and study arms

Exercise

Behavioral

12 weeks of aerobic exercise, with 4 sessions per week.

Primary outcomes

Percent change in blood oxygen level dependent (BOLD) response to visual food cues as measured by functional magnetic resonance imaging (fMRI)Baseline, 12 weeks

Percent change in blood oxygen level dependent (BOLD) response from baseline to after the 12-week intervention period while viewing visual food cues. The primary contrast of interest is the comparison of high-calorie food images to nonfood object images.

Change in serum cortisol response to counting taskBaseline, 12 weeks

Change from baseline to after the 12-week intervention period in serum cortisol levels (micrograms per deciliter (mcg/dL)) throughout a counting task involving mental math (measured as area under the curve).
