crunches will not lose body fat or weight. aerobic exercise such as running will reduce body fat. it takes 3500 calories to make a pound of fat. reduce your intake by 500 a day/7days = 3500. With exercise, you should lose a pound a week. p.s crunches or resistance work will only tone the muscle but fat will stil be over it.
3,500 calories = 1 pound of body fat
doing crunches makes muscle on top of fat and after that its almost impossible to lose that fat!
It take about 3500 calories to burn 1 pound of fat. So that would mean that if you lower you caloric intake by 500 calories in a week you would lose about 1 pound.

I don't understand your question, but I think you are asking how much weight a 203 pound person can lose in one day. Several factors influence weight loss, such as BMR (basal metabolic rate), hydration, and exercise. If you lose a lot in one day it is often due to dehydration. There are 3500 calories in 1 pound of fat. In order to lose weight, your body needs to burn more calories than you take in. Therefore, to lose weight, you need to create a 3500 calorie deficit per pound of fat you want to lose. However, this deficit should be a sum of the calories you don't eat over a period of time. For example, if you have a 500 calorie deficit each day for 7 days, you will lose 1 pound of body fat per week. Losing weight at a really fast rate is not healthy, and according to the set-point theory, you are more likely to gain weight back if you lose it quickly.
You can find tips on how to lose weight and calories at the following website that provide to help you, http://www.aworkoutroutine.com/how-to-lose-fat/.
you have to lose calories you do that by excising and lose 500 calories each say for one week no junk food you will lose 1 pound in a week if you only lose 500 calories each or 1000 each day you will lose 2 pounds
eat a lot celery all day and drink 3 cups of green tea. You would eat no food to lose weight but skipping out on food would not guarantee losing a pound in one day. In addition, you would add stress to the body by trying to lose that much weight. To give you an idea: one pound of body fat is equal to 3,500 calories and unless you are eating that much a day, you won't lose one pound. You can also lose water weight but when you start eating and drinking regular food, water weight comes right back.
