About 2 from breathing. Keep moving.

you will lose on average 150 calories doing 230 sit ups.
Barely any, maybe 1 or 2 calories for a whole situp.
The number of sit-ups that you need to do to lose two inches depends on many factors. The first is how much you weigh when you begin. The second is how long it takes to do those sit-ups. The faster you do them, the more calories you burn. Doing 100 sit-ups in 10 minutes will burn approximately 57 calories.
It depends on how many calories you eat versus how many calories you burn through this exercise.
3500 calories equal 1lb of fat. So a reasonable weight loss is to cut out 500 calories a day and lose an average of 4lbs per month. To answer the question as is, she needs to cut out 1500 calories a day. That's the basics. Of course you can sit down and figure out Basic Metabolic Rate and how many calories it takes to maintain that 200 lb weight each day, then cut out calories from there. There is a formula out there for that.

Sit-ups have to be done briskly in order to burn a significant amount of calories. Fifty sit-ups on average would only burn about 30 calories.
too many, cut down on the pies cheeky.
500 cal is a ridiculous diet, it's not sustainable and not healthy. If you only want to lose one pound you might as well go sit in a sauna for an hour or so and you'll lose that weight until you reach for a bottle of water again.
Yes, standing up burns more calories than when you sit.
It would be practically impossible to lose weight just with exercise alone. An average person weighing 145 lbs. would need to perform a total of 17,500 sit-ups in order to burn a pound of fat which is equivalent to 3500 calories. This is why doctors recommend combining diet and exercise.
