Women who exercised a lot for 12 weeks lost fat and gained muscle, but also felt hungrier and ate more snacks.

When overweight or obese individuals perform aerobic exercise that burns at least 1,500 kilocalories per week without changing their diet, their bodies do not fully offset the extra energy burned, leading to a net rise in total daily energy expenditure.
In overweight women, doing 12 weeks of supervised aerobic exercise does not lead to less movement during daily activities or more sitting, but it is linked to less total time spent sitting.
Over 12 weeks, doing supervised aerobic exercise that burns 500 calories five times per week is linked to a decrease in body fat and an increase in lean body mass in women who are overweight, with an average BMI of 27.9.
In overweight women, doing supervised aerobic exercise for 12 weeks is linked to eating more food overall, snacking more often, and feeling hungrier before meals while feeling less full, which may reflect an adjustment in eating behavior in response to increased physical activity.
Overweight women who engage in 12 weeks of supervised aerobic exercise experience measurable decreases in waist size, total body weight, and body mass index.
