It takes about 3500 calories to lose a pound. You can lose weight by eating 3500 calories less than your body needs or by exercising away 3500 calories.
For example, if your body needs 2000 calories a day to maintain its weight with your current activity level, if you ate 1500 calories a day for a week, you'd have a 500 calorie a day deficit. Times that times 7 and that's 3500 calories which should translate to about a pound loss in weight.
Or if you eat 2000 calories a day and jogged for 9 hours a week, the jogging would burn about 3500 calories and you'd lose about a pound.
Eating fewer calories a day is the easier way to weight loss, but exercise can supplement it and tone your body. Also, as you replace fat with muscle, you'll burn more calories.
