If your between 20-40, you should not take in more than about 2,500 calories/day. If your closer to 60, about 2,300. There are 3500 cal in a pound of fat. If you intake 2000 cal a day, in 7 days, you would lose 1 pound. (2500-2000*7) If you increase you exercise/activity level, you'll lose it sooner.
That all depends on how many calories you are eating, and what your baseline need is. Let's say your basic need is 2000 calories, and you eat 2500 cals. That means you need to burn at least 500 cals on exercise to start losing weight. Rule of thumb says that when you're 3500 calories short, you've lost a pound of fat. So in this example if you exercise for 600 cals every day it'll take you 35 days to lose one pound. But maybe you're only eating 2000 cals/day, then you'd lose one pound every 6th day you keep it up - assuming that your numbers for your food and exercise are correct.
