Hey good morning and happy new year all, I bought this cool watch the other day it tells my heart rate at the push of a button.. it tells me how many calories i burn with a timer on it.. it has another timer.. it has a alarm.. its waterproof.. its a really cool watch i bought from the weight watching side of walmart, I wore it for the first time yesterday, and by accident i erased all info from my adventures in selling gs cookies with my daughters... we were out for around 5 hours walking around town.. it was a fun time... anyway after my shower i put it on to sleep in to see. and it told me i slept around 8.5 hours and burned 2000 calories, my question is how accurate is this and do you actually burn calories when you sleep?
Thanks everyone! :)

    burn 2000 while sleeping 8.5 hours? I would say return the watch and get your money back.

    You do burn calories in your sleep (you burn them until you're dead) but I don't think you burn that many unless you were sleep walking all night!

    You are constantly burning calories every minute as you breath and your heart beats. But if your BMR is around 2500-3000 for most people (the calories you burn just being alive) 2000 for only 1/3 of the day and the resting 1/3 at that, sounds a little high to me, but I am no expert, but yes you do burn calories in your sleep, but only as a part of your daily metabolic functions.

    you do indeed - always, but not 2000 - lol

    You burn between about 60-80 calories per hour - depending on your gender, weight, ect...

    I just the calories burning calculator on my phone and for me (I weigh 196) sleeping 8.5 hours would burn 634.7 calories.
    Hope this helps. Have a GREAT New Year!!!

    Well, you definitely burn calories when you sleep. It's part of your BMR, the calories your body burns just by functioning (breathing, digestion, etc.). However, 2000 seems like way too much to be accurate! I use a BodyBugg to measure my caloric burn & I average around 0.8 to 1.1 calories per minute when I'm sleeping. Do you have it configured properly for your height & weight?

    I have the bodybugg, i burn around 650-800 calories if I sleep until 8-9 am. There is no way you burned 2000 calories in sleeping, haha. Maybe for the entire day. I burn about 2500-2600 a day

    I'm going to say that's not very accurate.

    What is your BMR? that's basically the amount of calories your body would burn if you slept for 24 hours.

    Yes, you do burn calories while you sleep. But not many. If your BMR is 1500 then you would be burning about 60 calories an hour sleeping. So for 8.5 hours, about 510.

    If you look under the "tools" tab there is a BMR (Basal Metabolic Rate) calculator. It gives a general caloric use per 24 hours based on BMI (Body Mass Index).

    2000 calories sounds pretty high for 8.5 hours of sleep, but if your watch calculates calorie use by heart rate, maybe you had some exciting dreams! :)

    Yes you burn calories (thinking, breathing, digesting, moving slightly, maintaining body temperature, running repairs) while sleeping, but nowhere near 2,000 calories overnight

    Go to tools on the home page and you'll find a BMR calculator. That gives an approximation of your basal metabolic rate per 24 hours, ie what you'd burn if you lay flat on your back and did absolutely nothing.

    If you want a heart rate monitor to give a reasonable guess at calories burned (and then only for exercise) you need a proper heart rate monitor with a chest strap.

    if you want to monitor estimated calorie burn 24/7 you can get a body bugg but they cost a fortune.

    But if your BMR is around 2500-3000 for most people


    As a woman, I can tell you that 2500-3000 is not the BMR for "most" people! (Maybe for most men, I don't really know...) Oh, how I wish it were, though... That would make this journey SO much easier for me. :laugh:

    Yeah, no kidding! I'd love a bmr of 3000. Even if grocery shopping would get more expensive!

    I burn about 600 to 650 calories while sleeping a eight to nine hour night. 2200 calories daily

    I have a bodymedia fit band I wear 23 hours a day. I burn 500-800 calories while sleeping. 2000 calories burned would probably be your total for the day.

    Yes you do!! I took a nutrition class last semester. I dont know how high the number would be. Your BMR is the number your burn while at complete rest. You can actually raise that number to work for you, by eating right and exercising. The body will burn more at rest, but it takes a whole lot of time to make a drastic change

    It would really depend on your bmr, and some key factors in that are your age, weight and gender (though in reality a lot of things effect our metabolism). I will say, most heart rate monitors are not designed to track calorie burn on things like showering and sleep so I would not really trust their accuracy on that.

    Oh me too, mine's 1090 right now and if I lost another 7lb it would only be 1050. Thank goodness for an active working day and for exercise!

    It is inaccurate. Approximately 70 calories per hour are burned when sleeping.

    I presume that watch is a heart-rate monitor watch. They are only meant to be accurate during exercise, if used at all other times, the calorie counts are inaccurate. Even the manufacturers of the watches state the same.

    (It sure would be good if 2000 calories were burned during eight hours of sleep though lol)

    Of course you burn calories while sleeping, the body burns calories 24/7. However, a heart rate monitor is only designed to track calorie burn during steady state cardio exercise, it's not going to be anywhere near accurate for all day use, or weight training, or even necessarily intervals. It relies specifically on your change in heart rate, and compares your resting heart rate to the elevated rate, and calculates a calorie burn off of that. Your heart rate only applies to caloric burn while doing steady state cardio, where your heart rate is elevated a specific amount, for a specific amount of time. The rest of the time, various other systems take over that have nothing to do specifically with your heart rate, making an HRM mostly useless.

    Thanks everyone! Im going to check of the page you all told me about.. I understand that I did not burn that many cal at sleep.. I was just curious about how many you do burn. Thanks for all the info.
