Does exercise really help you lose weight or does it make you hungrier? how can you fight over eating after exercise?

Water, small meals: Weight loss occurs when your body uses up more calories than you take in. Exercise causes your body to use more calories, and also can speed up your metabolism so that even when not exercising you are using more calories. Try to eat low calorie foods after exercising like vegetables, drink a lot of water. Also eat smaller meals more frequently.

Exercise hunger: Studies show for weight loss you need only 150min/week of exercise. When you do more, you are more hungry and consume more calories thereby reducing weight loss.
