Over time, changes in body fat mass result from the consistent difference between the amount of energy consumed and the amount of energy expended.
In previously sedentary, overweight or class I obese women, a structured 10-month exercise program involving high-intensity circuit training three times per week is associated with a reduction in body mass and body fat, along with increases in fat-free mass and resting metabolic rate, due to higher energy expenditure without changes in diet.
In overweight women, high-intensity circuit training can raise the number of calories burned at rest by 6–10%, which helps reduce body fat over time even without changing food intake, due to increased muscle mass and higher energy use after exercise.
After 10 months of high-intensity circuit training, sedentary overweight women experienced a 27% increase in aerobic capacity and muscle strength, and about half of those gains remained after stopping training for 5 months.
After stopping 10 months of intense circuit training, overweight women lose some of their fat loss and fitness improvements over 5 months, but not all of it—body fat goes up slightly and aerobic fitness drops a bit, yet stays better than before they started training.
