So i'm having this issue where my garmin is saying I burn arond 4k calories a day. and Mfp caloric intake goal is at 1850 a day.

now my issue is that i went to my doctors and used an accurate vo2 machine to determine how many calories i burn at rest, being active like working, and exercise. the total for that comes out to be 2700~ calories. and the test says i would have to burn at least 220+ calories from exercise, and about 500+ from daily work.

now the way for me to lose weight said I nees to eat between 1900-1600~ calories a day. i have mfp set at logging my meals down so i eat about 1850-1900~ calories a day.

now this makes sense if you subtract 2700-1800=900 which is the #~ i should i have end every day at to be in a weight loss mode.

so i do have a garmin chest strap and my garmin vivosmart takes my calories from active and resting, and garmin says that i burn about 3800-4k~ calories a day.

3800-1800=2000 which would be the number i have left over daily making it very hard to lose weight. so does anyone have any idea of what i'm doing wrong or calculating wrong? or should i igonre my doctors test and put trust between garmin and mfp?

    Are you wearing the HR chest just during exercise?

    In Garmin Connect: On the activities tab: How many calories are burned in exercise.

    In Garmin Connect: On the activities tab: how many calories is it giving you for steps taken during the day.

    What is the total for both on the page? What does total calories say at the top of page?

    Make sure your personal stats in Garmin (height, current weight, age, etc) are the same in both Garmin and MF. You might want to lower the activity level in Garmin to 1. Garmin uses a special algorithm to come up with total calories burned.

    Did you calibrate Garmin with VO2 information, change or update running or walk stride, anything that customized your device?

    Also, do you have your Garmin synced to MFP? MFP gives you a goal BEFORE purposeful exercise, you get extra calories for exercise.

    No, I wear the chest strap constatly. When I get home from the gym I take the chest strap off and wash it. Here are 2 screenshots from yesterday
    Screenshot_20160923_214830.png Screenshot_20160923_214841.png

    Both stats are the same betwen garmin and mfp. And I know mfp gives me extra calories, so I don't really use the calories burned on mfp.

    My V02 sheet from my doctors is at 3.48ml/kg/min. But that's at rest. and not at running or bicycling as to what the only 2 v02 settings garmin has.
    Also, do you have your Garmin synced to MFP? MFP gives you a goal BEFORE purposeful exercise, you get extra calories for exercise.

    Yes I have both synced. I don't really rely on MFP to give me accurate calories burned. I'm really wondering why garmin has my calories burned acting like I'm an olympic athlete.

    I do a lot of walking at work. I walk about 4-6 miles 5 days a week. Along with going to the gym. Soo idk.

    No, I wear the chest strap constatly.

    First of all, stop doing this. You should only be wearing the chest strap for purposeful cardio exercise, not at all times.

    The other question is, do you have negative adjustments enabled?

    I tried looking up the settings for negative adjustment and I don't have that option. using an androird samsung s7.

    and why would i only wear my hr strap during exercise? i still burn calories before and after i workout. shouldn't i be wearing it for an accurate to a degree measure.

    It is your heart strap.. so you can do with it what you want.. but you are not supposed to use it in the way you are. I do believe that you need to do so some research perhaps on HR monitors in general and their use for exercise.

    So, stop wearing your in the capacity that you are.. as this is not what this is for. It is for exercise.

    If you can log into the web, negative adjustments are found under diary settings..

    well why is my strap for exercise only but people wear their watch with the HR built in to the watch all day?

    OP the HR strap is a transmitter. The HR wrist monitor are optical devices and are not the same. If you want a device to track HR/pulse etc all day long for you, you might want to consider getting a smart watch or optical device such as a wrist tracker.

    Wrist read HR devices are more inaccurate and I believe, only track something as purposeful exercise above a certain heart rate. Chest straps are not designed to be worn all day as you're essentially saying you're exercising at some level all day long, which isn't the case. You should do some research.

    I asked about negative adjustments because there is an issue with them taking away too many calories due to a new algorithm started using earlier this year. I was getting robbed of a fair number of calories and ended up turning negative adjustments off. I believe you need to go to settings on the desktop version of MFP to turn on and off.

    ^^^ All of this true. I too have turned off neg adjustments as well. :)

    And the new total calories burned algorithm is tough to understand and a bit cumbersome as I cannot really explain it. That is why I wanted to see the activities page from GARMIN CONNECT via web..

    Well, you helped me @RoxieDawn! For quite a while I've been wondering why I earned so few calories for my steps. About 320 for 22,500 steps. (I'm 5'3 and 115.) after reading this, I checked my activity level in Garmin Connect and it was set at 8. I get a lot of steps and exercise, but am sedentary at work (desk job). All my movement is very intentional and has to be planned and added--it doesn't just happen. Changed the activity level to 2. Let's see what that does! :smiley:

    OP, I wear my chest strap during intentional cardio. Only.

    see i don't see why i'd want to use a wrist watch with built in HR that isn't as accurate as using a chest strap HR and seperate watch.

    If the chest strap gives a more accurate reading why would a built in wrist watch be better for at rest/post exercise.

    That is really high. My Garmin actually runs quite low and tells me I burn 1600 calories in a day when I exercise but in reality I can eat 2000 a day to maintain. I don't pay attention to the numbers on there anyway to be honest. I just eat the amount that works for me. Like others mentioned, I only wear the chest strap during exercise, not on walks or things like that. You're essentially double dipping because you're getting extra calories for steps and extra calories for whatever the hrm says.

    Well I'm only going off of what Garmin is telling me. Then I'll take the number that Garmin says that I burned between resting and active. And then subtract that number from the calories I've logged through MFP. I just don't get why Garmin is giving me an incredibly high calorie burn reading.

    So everything that I'm reading says that the chest strap gives an accurate reading for exercise and alltogether vs optical reading. and an optical is accurate only good for walking and some jogging. So there's no reason for me to switch to an optical reader if the chest strap will always give a more accurate reading.

    But the chest strap is not designed to be worn all day. That is not its purpose. That's also the reason wrist read devices don't use HR for calculating calorie burns for normal day to day activity either. It's a misuse of the technology.

    Tracking steps is a perfectly accurate way of tracking energy expenditure outside of purposeful exercise. I too have no real interest in a wrist read device because I see no benefit over just pairing a more accurate chest strap when I exercise.

    We already explained this is you.

    I believe that you are over thinking this quite a bit and still have the two different type of devices confused. The constant use of HR strap (and I am surprised that anyone would want to wear this even if hard or soft strap) is giving you erroneous calorie burns.

    With all of this said, no device is 100% accurate rather it is optical or HRM you are currently using. The HR monitor that you have chosen is a perfectly good choice that can give you a close enough approximation of energy expended through exercise but NOT daily energy expended while watching TV, sitting at your desk at work, grocery shopping, brushing your teeth, cooking, etc..

    Garmin calculates steps data separately anyways, and this is handled in MFP through the negative adjustment. So what you are doing is not doing you any good to obtain a total daily calorie burn output.. Perhaps you will figure all this out as you get used to your device and working with calories over a period of time.

    Once you figure out how all of this works, you may decide that leaving this option OFF is better choice. You might want to turn it on if you want to further analyze about all this works to see the difference between MFP and GARMIN paired data.

    No I fully understand that no device is 100% accurate. And I get that you're saying that the heart strap is not accurate for sedentary activity. But it doesn't make sense that having a watch with HR monitor built in would be somewhat accurate for sedentary activity compared to not wearing a heart strap which gives more accurate data.

    The only answers I've received so far is that a Heart Strap is used for exercise activity. And that is uses a beam technology. I get that. That doesn't explain why the chest strap that's attached to me that gives me an inaccurate reading of my BPM would give me a mis-calculation of how much I burn before activity and after activity. The only answers I've recieved so far is "Because so".

    And I get this. I don't trust a watch with an HR monitor built in. Every internet article that reviews these devices always recommends using a Chest strap.

    Again, you need to do some research on your own. I am liking this that explains how HR work with exercise.

    For example, if you were really stressed out, upset, mad, angry and wearing your heart monitor, its gonna spike that heart monitor and give you erroneous calorie burning you are trying to track during your stress episode. This calorie burning that you did during this stress episode is included in your BMR calories, NEAT, etc. You burn calories at rest (BMR), though NEAT, EAT, TEF, etc.. the heart monitor cannot track all of this EXCEPT "EAT",

    If you know nothing about this stuff time to research it..

    If you don't believe us that you shouldn't wear the chest strap 24/7, why don't you call Garmin and ask them?

    The reason your burns are so high is because you're wearing the chest strap--everything is being counted twice.

    Garmin takes into account your BMR automatically. And it adds exercise on top of that. Since you're logging all daily activity with the chest strap, it's double counting the activity. Once without the chest strap, and once with it.
