Anyone else only have 10lb to lose?

Hi, In my profile pic I am 12 pounds less than I am now, I wan to get back to this weight in time for my holiday in April.
I am on week 6 of 16.
I need 1700 cals a day to maintain (im 5'3") so im eating 1200 cals a day at the mo in the hope ill lose 1lb a week.
I know I need to have a deficit of 3500 cals a week to lose 1 lb a week.

Any one else already slim but have few pounds to lose?

The reason I want to lose weight is to get rid of some of the fat on my stomach, hips, thighs and chin :)

May be worth mentioning that I have a desk job and log all exercise.

Is 1lb a week reasonable? If any has done the same sort of thing when did you notice a difference?

Thanks
