Question on net calories

Lysander666

Right, I will try to keep this as simple as possible. I'm looking to lose 2lb per week. My BMR is 1600 kcal, and my net calorie intake is 1200 at the moment. A pounds of fat is something in the region of 3500 kcal.. so at this rate I should lose only about 1lb per week, but MFP says I will lose two. How is that possible? I must be missing something because my deficit is only about -400 per day.
