It depends on how fast you want to lose those 15 pounds by. To lose one solid pound of body weight, you need to burn 3,500 more calories than you consume. For 15 pounds, that means you need to burn 52,500 more calories than you consume.

Here is the breakdown of the time it would take and the calories that would need to be cut out.... (this is also assuming that you are exercising and burning a considerable number of calories, daily, too.)

* 1 month = 1750 calories less daily.

* 2 months = 875 calories less daily.

* 3 months = 580 calories less daily.

* 6 months = 290 calories less daily.

* 1 year = 145 calories less daily.
