In postmenopausal women, doing more aerobic exercise per week—whether 150, 225, or 300 minutes—does not consistently change how much the body reduces its other energy use to compensate for the extra...
Mechanism
Synthesis from 1 study
When these women exercise more, they end up eating more and moving around less during the rest of the day, which cancels out the extra calories burned. That’s why doing more exercise doesn’t lead to more weight loss—it’s not that the exercise doesn’t burn energy, but the body adjusts to balance it...
Most probable mechanism
When these women exercise more, their bodies respond by making them feel hungrier and move less during the rest of the day, so they end up burning about the same amount of extra energy no matter how much they exercise.
Increased aerobic exercise volume elevates total daily energy expenditure
Elevated energy expenditure stimulates hormonal signals that increase hunger and food intake
Increased energy availability from food intake reduces the net energy deficit created by exercise
Non-exercise physical activity, such as fidgeting or walking, decreases to offset the additional energy cost of exercise
