Exercise-Induced Gut Permeability in Normal-weight Obesity

The investigator's overall goal is to examine how indicators of gut permeability change in response to exercise in individuals with normal-weight obesity (i.e., normal body mass index \[BMI\] and high body fat percent) relative to those with a normal BMI and low body fat percent and those with a BMI in the obesity range and high body fat percent. The investigators will examine indicators of gut permeability (specified in primary outcomes) in response to a short, intense bout of exercise (i.e., VO2 max test on a cycle ergometer) and sustained, moderate bout of exercise (i.e., 45 minutes at 65% measured VO2 max on a cycle ergometer). Additionally, the investigators will measure basic anthropometrics, blood lipids and glucose, and body composition with DXA.
