Calorie burn

Hi, quick question about calorie burn!

I just read this on a website: Metabolic Rate is the rate at which the body burns up calories. A body that consumes 2500 calories a day, and burns 2500 calories a day will stay at the same weight. A body consuming 2500 calories daily but burning only 2000 will gain weight at the rate of about 1lb a week.

OK - if this is true how can workouts be effective? Taking the example of my calorie allowance for a day, 1200 - I would have to work off more than 1200 calories to lose weight by those guidelines. That's hours of exercise. Am I missing something? I thought I was doing well by sticking to my plan and exercising as much as possible.
BTW I am following the myfitnesspal app which tracks calories for the day and recalculates when you input workouts/exercise.

Thanks for any info!

    Follow the guidelines here to determine what your body is really burning & what you should be consuming.

    That is a fantastic article, and EXACTLY what I needed to read this morning. I have all the links saved and am going to recalculate today.

    THANK YOU!

    What you're missing is that your body is burning calories just to be alive. If you never got out of bed it is likely you would burn off your 1200 calories.

    You burn calories just keeping all your organs and systems functioning, digesting your food and living your daily life, in total far more than most people burn in formal exercise.

    Hello,

    Hope this helps.......If you burn 2500 calories a day but only eat 2000 you will be short 500 calories. Your body needs to then use 500 calories from stored fat. If you do that for 7 days you will lose one pound. 7 days x 500 calories = 3500 which is one pound. Now, if you exercise and burn say, 500 calories, you get to add that to the 500 deficeit you already have. So then you would be short 1000 calories a day.. if you did that for 7 days, you would then lose two pounds. 7 days x 1000 calories equals 7000 calories. 7000 divided by 2 equals 3500 or one pound. So, 7000 calories equals 2 pounds gone. I hope that makes sense! Good luck and keep up the good work!

    Your body burning 1200 cal per day as rest position if you take 1200 cal per day and exercise, you should add exercise calories to daily burn rate.

    What she said :)
    The details can get horribly complicated, for instance if you eat a lot less your body tries to conserve calories and slows down..... etc... all these are just refinements of the logic above

    Thank you for the answers everyone. Now apologies if I sound silly, but if by the case that the body burns 1200 at rest position, does that mean that anything extra burned in my case is the starting weight loss number? I.e. if I burn 300 to 400 calories a day while keeping under my 1200 consumption goal, then I am on track to slim down?

    Also, thank you lauramacaroni for the awesome link!

    Exactly. For example, I have been sick the last few days so I am just laying around. I know I have to knock a couple hundred calories off because I am not burning as much.

    If you stay the same weight at 1200 calories a day and burn 400 calories a day you should lose but less than a pound a week because 400 x 7 is 2800 calories and it takes 3500 to lose a pound. So you would need to cut an extra 600 calories from your diet to lose a pound. 1200 is very low though, I bet you burn more than that in a day.

    Thanks! : ) I was just reading that link that was posted above, and one more question! How relevant is that Body Fat indicator? It says on some websites that between 20 and 25 percent body fat is considered 'fit' but I feel that I need to knock off some of it. What does anyone consider a healthy body fat percentage, or does this depend on the height or shape of a person?

    Your calorie allowance from fitness pal already cuts calories so you lose weight.

    I can't imagine bringing my daily calorie intake to 600 calories. Maybe 1,000 but when I do that the app tells me I am getting too few etc.

    Sorry, I meant 600 calories a week not a day. I am sure on 1200 you will lose, especially if you do not add back in your workout calories. I would not go lower than that.

    The 1200 calories you have mentioned are irrelevant if they are the calorie goal set by MFP.

    If you want to follow the "eat less than you burn" method, first you have to know how much you burn, and I can guarantee that 1200 isn't it. Most peoipek would burn more than that if they did nothing but lay in bed all day.

    Work out your TDEE (Total Daily Energy Expenditure = calories used per day) as a starting point, and then you need to deduct your deficit.

    Thanks for that Ladyraven! I found a TDEE calculator and have discovered that I am about 40 - 50% under my expenditure, so it's all good! : )

    Actually it's not good.

    50% defict is too large, you should only be at 10-15% defict.

    Ok, thanks. I am eating three normal meals though and only working out for about 30 minutes a day. Maybe the calculator was wrong. It said 2100 was my expenditure. I hope I am not doing it incorrectly yet again.

    Sorry - I thought I was replying to someone else who only had 10lb to lose.

    I have no idea how much you have to lose, so should not have said you should be on 10-15%.

    For fat loss most sites would recommend a defict of around 20%.
