You burn calories in 3 main ways:

* Your metabolism, or what you burn just keeping your natural body functions (breathing, heartbeat, digestion, etc) ticking over. Most people burn between 1300 and 1900 calories per day. (Google 'BMR calculator' to get a better fix on this number for you).
* Normal daily non-exercise activities. Generally reckoned at 20% in addition to your BMR for a sedentary lifestyle.
* What you burn through exercise - probably 200-500 calories for most people for a 30-60 minute workout.

As you can see, exercise is a fairly small component in you overall burn, although useful in swinging a small calorie surplus (which will have you gaining weight) into a calorie deficit.

And at 1200-1500, you are probably already at a deficit even before you start working out.

Oh goodness me no! You don't burn that much in a workout. You'd die. :)

Your body burns somewhere around 1500 calories a day just by existing. So your exercise adds to that, say 300 calories of exercise for a total of 1800. Then if you eat at, say, 1300, you've created a 500 calorie deficit today - just right for a pound a week on average.

You don't exercise ALL your food off! Your body burns most of it just being you! :)

it's not about doing that. 3500 calories make 1 pound. have you set up your workouts and what you eat........? by doing that sparks has set up for you how much you need to eat in calories and then by working out you will loose weight. remember you don't need to eat back those calories you work off.

Soo...a little new to this weight loss thing.

Little confused on this calories in, calories out thing.

Like if I consume 1200-1500 calories a day, how in the world is it possible for me to burn off that many calories in a workout!!??
