CR: Caloric restriction; CR+EX, caloric restriction and exercise

No significant differences were observed between CR and CR+EX at baseline. Similar decreases between CR and CR+EX in body weight, BMI, fat mass, and body fat percent.

^*p = 0.026 for group*time interaction, indicating significant difference in magnitude of changes between CR and CR+EX after interventions.

^†p = 0.038 for group*time interaction, indicating significant difference in magnitude of changes between CR and CR+EX after interventions.
