I can't see your history so it's hard to be specific.
If 16 hours of resting and 8 hours of sleeping equals 2404 calories burned then that it the number of calories you should eat to maintain your current weight. Obviously that is not what you are trying to do.
In order to lose 2 lbs a week you need to beat that number by 1,000 calories a day. Every day. Remember that you are burning about 100 calories an hour doing nothing so if you walk for an hour and burn say 450 calories you really only burned 350 calories more than doing nothing.
In your diet calendar you need to get the net to be under whatever your goal is for the day.
Pain is a by-product of a good time.
