Calorie Consumption Question?

Can someone explain this to me?
I know that to lose weight you must burn more than you consume in terms of daily calories…
Here is where I may sound a bit stupid, but…Let’s say I eat below the “average” diet of 2000 calories a day; I eat 1700. How do I burn more than that in one day? I spend 30 minutes doing fairly intense cardio at the gym and burn about 300. I do anaerobic exercise as well, but I couldn’t assume that this burns as much as cardio.
How do I burn more than I take in without cutting my caloric intake to about 700 a day (unhealthy) and staying at the gym all night?

    Your body naturally burns calories all day long…you have to do a burn rate calculator or see a doctor to figure out how many calories your specific body specifications burn a day……I did the calculator and it told me I burn about 1600 colories a day, and being put on a program, that means I can eat about 1350 calories a day to slowly loose weight (the healthy way with a healthy diet). You burn calories all day long, so the more excersise you do, the more daily calories you burn and once you boost your metabolism (by working out and getting into shape) your body will burn even more calories naturally per day.

    Well, your body doesn’t burn calories only when you excerise. Your body is always burning calories, day and night, while it carries out its regular functions like your heart beating, digestion, etc. Even when your body is “at rest”, it is burning calories to the tune of about 750 to 1,000 a day. I don’t know it off the top of my head, but there is an equation you can use to figure out how many calories you burn during the course of a day based on your resting heartbeat. But if you’re clocking in at about 1,700 calories a day — and you keep up your exercise routine, you should see a regular and steady weight loss, especially if you’re a man. If you’re a woman, you may want to cut your calorie intake back to between 1,200 to 1,500 calories a day.

    In order to lose weight you must use more calories per day than you consume. BUT, if you don’t do any physical activity calories are still burned in your body just for normal body functions; maybe 80 or so per hour. So you have to take that into account when you are counting calories.
    If you consume 2000 calories a day and spend 30-45 minutes per day in medium to strenuous exercise, you will lose weight.

    What you are missing here is your AMR and BMR. Active Metabolic rate and basal metabolic rate. BMR is how many calories you burn just laying down, breathing, living. AMR is how many calories you burn during your normal daily activity aside from exercise.
    Example my BMR is 1,490 calories, doing NOTHING
    My AMR is 2,490 calories just doing my normal stuff, waking, eating, showering etc..
    So in order for me to loose weight I MUST eat less than 2,490 calories. To see a measurable weight loss I’m cutting my calories to about 1,400 per day and I’ve lost 10lbs in one month and I’m definitely not starving. I can eat upto 2,490 per day and not gain weight but stay at my current weight.
