It depends on your weight, and body make-up I'm afraid. Even someone your height and weight, but who has a different Lean Muscle to Fat ratio will have a different experience.
To lose 1lb a week, you need to burn 3500cal more than you take-in. Which is 500 a day. So for 2lb it will be 1000cal a day. If possible I would recommend trying to achieve the majority of that through increasing your exercise wherever possible (I try and walk for at least 45 mins a day).
42" jeans(25/01/2013) 40"(28/02/2013) 38"(20/03/2013) 36"(25/05/2013)
Down from 60" waist jeans since June 21st 2012.
Still keeping to my 26" jeans, but they are too tight for comfort. too many tasty things in the US, and over Xmas.
