To do this you will need to eat 1000 calories a day under your maintenance level.
There are 3500 calories in a pound of fat, So you will need to burn 7000 calories a week which works out at 1000 a day under your maintenance.
The average women needs to consume 1700 (ish) calories a day. You will need to eat 700 calories a day for 6 weeks.
If you want to do this then here is a diet plan.
breakfast - 50g oats and semi skimmed milk (280 cals)
lunch - Ham sandwich (220 cals)
dinner - 1 chicken breast, 50g new potatoes + greens (200 cals)
And thats it. No snacks, no coffee, no sugar, just the above if your that serious.
If you want to eat more then i am affraid the only solution is exercise. The average person burns 300 calories for 30 minutes running. That will buy you another meal.
Oh and some advice "fat" does not make you fat. Eating more than your body needs does.
