2,000 calories!!
The rule that a doctor told me was to multiply your weight by 10 and that is what your daily intake should be to maintain your weight. Similarly if you want to lose weight, tally your daily intake for a week, find your average daily intake, and reduce that by 500 calories. So for instance I weight 175 pounds, so I should be consuming 1750 to maintain my body weight.
To maintain your weight you simply need to expend the same amount of calories that you intake.
