Blaze Heart Rate Zones / Custom Zones

[dinaree]

After wearing my Blaze for four weeks now I find somehting very interesting and have to question the accuracy. On an average day with NO excericse, my tracker says I'm in the Fat Burn Zone 11+ hours per day. Therefore, my calories burned is always over 2000.  This just seems way too high.

Having done some reading up on heart rate zones, it seems that Fitbit has my fat burn zone on low end - 50% of my max heart rate and starting at 86 bpm. Everything I read elsewhere says my fat burn zone should start around 60% and at 105 bpm. 

I created a custom zone with 105 as my low limit and 175 as my max. What I am finding however, is that the device itself will now only say 'In the Zone' if I am within that 105-175 range that I created (as opposed to indicating fat, cardio etc as it did before I created the custom zone). The APP though is still categorizing by fat, cardio etc. Why is there a discrepancy between the tracker and the APP?  If I create a custom zone, shouldn't the tracker and the APP both reflect that? 

My goal in all this to prevent the device from saying I'm saying I'm in the fat burn zone when I really am not. I would like to see a more accurate calorie burn. 

Thoughts? Suggestions? Much appreciated.

I'm assuming the heart rate zones are based on age and resting heart rate automatically. Although, I prefer seeing 5 zones and not 3.

When you make a custom zone there are only 2 zones, not the three.

The zones are based on your BMR, which is based on gender, age, weight . for an average person, but there is only 1 average person, everyone else will be higher add lower.

@dinaree Unfortunately the Custom Zones allow you to set a range for you and have no bearing on the calorie burned issue. It is more of a detection if you are monitoring your max and min HR.

Your Fat Burn zone is in the range of 50-69% of your max HR which is 220-age..

I am in the fat burn zone around 15 hours every day.  I was sick for a while and in bed and it was at 12 hours for the day.  I'm glad that I'm not the only one who is seeing this.
