without some specifics it's difficult to be helpful. How tall are you? Age? do you have a scale that will tell you your BMR (Basal metabolic rate).
In my experience, Fitday sort of over rates how many calories you burn a day. 2900 calories without exercize is a LOT of calories unless you are a very large guy (and if you ARE 177 lbs wouldn't be very heavy). Try choosing sedentary as a lifestyle and see what that gives you.
