Calories are not created equal. They are equal in physics sense, but your body is not a "bomb calorimeter" (device to measure caloric content of whatever). So maybe instead of cutting your calories in half, you cut less and replace carb calories with fat calories or protein calories. Or maybe you can even cut to 1000-1200 by replacing your calorie source with something else. For some weird reason carrots with butter work very well for me and I love the taste :-)
