BMR + calories burned through exercise will be your total calories burned throughout the day. So if your BMR is 1800, and you burn 400 with exercise, you burn 2200 a day. So anything below 2200 calories SHOULD cause weight loss.
If you choose to cut 500 calories a day off that, and eat 1700 calories, then you should lose 1 lb every week.
A 50 year old, 4'10, 100 lb female has a BMR of 1127, so with any exercise at all, she should lose weight. This is why 1200 is a minimum goal, not something people should aim for. A 40 year old at 5'2" and 150 lbs would burn 1411 calories just doing daily activity, so 1200 would cause weight loss, even without extra exercise.
Most people should not be eating just 1200 calories a day. Also, don't use exercise as a tool for weight loss. Most people who work out a lot to burn extra calories, cause themselves to become hungry, and eat extra calories because of it. Exercise should be for cardiovascular health.

Not only would that be near impossible for the average person (burn 1200 cals/day), you'd also probably pass out only eating 1200 cals while doing it! Breathe a sigh of relief; weight loss is not *that* hard.
Your body burns a certain amount of calories just to stay alive; breathing, creating new cells, organs functioning, etc. This is called your basal metabolic rate (or BMR). It means you burn calories just existing, even if you laid in bed all day and didn't lift a finger, you'd still be burning calories. Your BMR is estimated by your age, gender, body weight and height. There are other factors that can effect it but all you really need is a rough estimate. The average woman's BMR is around 1500 cals and the average man's is around 1650 cals. Sparkpeople already calculates your BMR when you enter your personal information into your account and they use this to calculate a calorie range for you that is based on the minimum amount of calories you should burn through exercise. If you burn more than Spark recommends, enter your weekly burn into your "fitness setup" and this will give you a more appropriate calorie range.
Your body burns a certain amount of calories through every day activities; showering, getting dressed, running errands, housework, standing, light walking, working at your job, etc. Spark automatically awards you about 300 cals extra a day for activity. You *can* change your activity level through your "account settings" on your "Start Page" if you work an active job.
Lastly, you burn more calories through exercise. An elevated heart rate in the cardio zone.
I'll put it into numbers. Say your BMR is 1500 cals and you add 300 cals for your daily activity. You burn 1800 cals a day without any exercise whatsoever. If you eat 1200 cals and you subtract it from the 1800 cals a day you burn, you get 600 cals. It takes 3500 cals to burn 1 lb of fat. If you ate that amount every day for a week, you'd create a deficit of 4200 cals/week which is equal to a 1.2 lb/week loss.
If you added exercise and burned an extra 400 cals, you'd now be burning 2200 cals that day. If you ate 1200 cals, you'd be creating a deficit of a 1000 cals. If you did that every day, you'd lose 2 lbs/week.
The safe amount for weight loss is 1-2 lbs/week. The more you weigh, the faster your loss will be (you have a higher BMR and burn more cals through exercise). The less you weigh, a slower loss should be expected.

EAYW47: Let's say that a person had a BMR( calories burned if lying in bed all day) of 1200. OK, now let's say that a person just going through the basics of the day doing typical daily activities burned 300 more calories. Now, she is at 1500. Say, then, that she did an additional 500 calories burned during deliberate exercising. Now she is at 2000. So any amount of calories that she consumes under 2000 should, in theory, contribute to weight loss. So if a person subjected herself to only consuming 1200 calories daily in the above scenario, she would, in around 4-5 days, lose 1 pound. I don't mean this to be exact or "scientific," but just suggesting that if one would only consume 1200 calories a day, she would probably lose weight steadily, assuming her metabolism didn't get screwed up, so to speak.
Most people burn at least that many calories just breathing, pumping blood and all of those other fun things that keep you body alive. The 1200 number is not what you are supposed to burn through exercise.

Please, no laughter. The question is-Does one need to burn 1200 calories a day if on a 1200 calorie a day diet ?
