Abstract

Background and Objective: Obesity is a widespread epidemic, which is characterized by an increase in adipose tissue and contributes to multiple diseases and premature mortality. Materials and Methods: A quasi-experimental study was designed and implemented in a balanced crossover design. Ten overweight women aged 20 to 35 years with a BMI>25 exercised on a treadmill for 40 minutes on two different days with an interval of one week in the fasting state and after breakfast at 45-55% of heart rate reserve. Appetite, calorie intake, and blood sugar were measured on the day of exercise and the day after. Blood sugar before exercise was significantly higher with breakfast than in the fasting state, but this difference was not observed after exercise. (P=0.015) Appetite before breakfast was significantly higher than after breakfast. (P=0.036) Appetite after exercise was significantly higher in the fasting state than in the non-fasting state. (P=0.017) However, there was no significant difference in post-exercise lunch calorie intake between the two conditions. In the fasted state, subjects consumed significantly more protein (P=0.009) and fat (P=0.039) and less carbohydrate (P=0.003) 24 hours after exercise, but these variables did not differ significantly 48 hours after exercise. Conclusion: Exercise can change the macronutrient ratio 24 hours after exercise.
