especially on a 1500 calories diet.. how is it possible to burn more then you eat if they say more then a hour or 2 of cardio isnt good an thats not even 800 calories within a hour.. will my bmr play a role into my calories that i eat per day like for example my bmr is 2400 will i lose 900 calories off of me if i eat 1500 a day?

    Your body uses calories just to function everyday.

    My stat estimates for yesterday (from fitbit):

    Total Daily Burn: 2526 calories (includes the 416 calories I burned doing 42 mins of cardio exercise)
    Steps Taken: 8938
    Total Food Intake : 2114 calories

    2526 - 2114 = 412 calorie deficit

    So yesterday, I burned 412 calories more than I ate. I'm 5'4.5" and 200.4lbs currently.

    "Definition: Basal metabolic rate (BMR) refers to the minimum amount of energy -- in the form of calories -- that your body requires to complete its normal functions, such as breathing, breaking down food, and keeping your heart and brain working. Age, gender, weight, and physical activity directly effect on basal metabolic rate."

    My estimated BMR is around 1695. So I eat at the very least 1695 calories a day if I don't work out or do much of anything (like I watch tv all day or when I get really into a game).

    What do you mean how is it possible?

    That would be a 900 calorie deficit. To burn one pound of fat you need to burn or be at a deficit of 3500 calories. Therefore at a 900 calorie deficit per day you would be losing 1.8 pounds per week. In theory, anyway. It also depends on your body, metabolism, water intake... etc.

    Calories are a measure of energy. The body uses energy in order to function, as well as for everything you do, including getting up out of bed, walking around and getting dressed. The amount of energy used for things like breathing, keeping your temperature at 37C and so on is called your Base Metabolic Rate, or BMR. This is the amount used if you lie prone 24 hours a day, not moving a muscle.

    On top of that you actually DO stuff, which adds to your energy expenditure. This energy plus your BMR is your Total Daily Energy Expenditure (TDEE), and varies depending on your level of activity. Someone driving everywhere and sitting at a desk all day will have a lower TDEE than someone working out 3 days a week. Mine is about 2800kcal/day.

    If you eat less than your TDEE you will lose weight, and if you eat more you will gain weight.

    its possible to eat less than your BMR cos your body will eat its own fat to get energy rather than get energy from food

    but isnt my bmr getting its own energy wich is burning my own calories if i was in coma because what is the 2400 mean then...? an then again if im suppose to eat my bmr then how come people have a diet at 1000-1500 calories a day wich is way lower then there bmr an once again how is it possible to lose more calories then you gain because eating 1500 or more calories a day is in possible to burn 1500 calories a day unless its excersise plus your bmr burning the calories because dont they say to much cardio isnt good? 1 hour of cardio is no more then 600 calories..

    Are you sure that's your BMR number? That sounds like your TDEE which includes your level of activity.

    It's a 900 calorie deficit from the posters BMR.... you take a deficit from your TDEE though. You really shouldn't be netting under your BMR for too long as it will increase muscle loss.

    OP, search online for TDEE calculator. That is how many calories you burn in a day doing your normal activity (and exercise if you factor that in).

    Omg! THANK YOU! I had the same question and didn't bother asking.
