dc.description.abstractWe hypothesized that exercise training would prevent gains in body weight and body fat, and worsening of cardiometabolic risk markers, during a 4- week period of indulgent food snacking in overweight/obese men. Twenty- eight physically inactive men (ages 19– 47 yr) with body mass index (BMI) ≥25 kg/m2consumed 48 donuts (2/day, 6 days/week; ~14,500 kcal total) for 4 weeks while maintaining habitual diet. Men were randomly assigned to control (n = 9), moderate- intensity continuous training (MICT; n = 9), or high- intensity interval training (HIIT; n = 10). Exercise training occurred 4 days/week, ~250 kcal/session. Controls did not increase body weight, body fat, or visceral abdominal fat. This was partially explained by a decrease in self- reported habitual energy (−239 kcal/day, p = 0.05) and carbohydrate (−47 g/day; p = 0.02) intake. Large inter- individual variability in changes in body weight, fat, and fat- free mass was evident in all groups. Fasting blood pressure, and blood concentrations of glucose, insulin, and lipids were un-changed in all groups. Glucose incremental area under the curve during an oral glucose tolerance test was reduced by 25.6% in control (p = 0.001) and 32.8% in MICT (p = 0.01) groups. Flow- mediated dilation (FMD) was not changed in any group. VO2maxincreased (p≤ 0.001) in MICT (9.2%) and HIIT (12.1%) groups. We conclude that in physically inactive men with BMI ≥25 kg/ m2, consuming ~14,500 kcal as donuts over 4 weeks did not adversely affect body weight and body fat, or several markers of cardiometabolic risk. Consumption of the donuts may have prevented the expected improvement in FMD with HIIT.en_US
