Energy balance
Exercise-induced weight loss is superior to diet-induced weight loss for reducing total fat, abdominal fat, and improving insulin sensitivity in obese women.
If you are trying to lose weight, combining exercise with a moderate caloric deficit is more effective for fat loss than dieting alone. Specifically, exercise helps you lose more total and abdominal fat while preserving muscle mass. Aim for daily aerobic exercise burning ~500 calories alongside a modest caloric reduction.
GoodSupportsHIGH confidence
In comparison with controls, a significant reduction (p < 0.001) in total fat was observed within both weight loss groups; however, the average reduction in total fat was greater (p < 0.001) in the exercise weight loss... than the diet weight loss group.
Why this rating
RCT design, clear statistical significance.

- Daily moderate-intensity aerobic exercise (approx. 500 kcal/session) for 14 weeks significantly reduces total, abdominal, and visceral fat in obese women, even when caloric intake is adjusted to maintain body weight (exercise without weight loss).Good
- Exercise-induced weight loss improves insulin sensitivity in obese women, whereas diet-induced weight loss alone does not significantly improve insulin sensitivity in this population.Good
