Summary
Simple datafield to accomodate a request by Susun.This field calculates the fat calories burned depending on heart rate zone & calories. The following defaults are configured:
- Z1: 9kcal burned = 1 gram of fat burned
- Z2: 80% fat
- Z3: 50% fat
- Z4: 20% fat
- Z5: 0% fat
In the settings you can:
- opt to see Fat Burner (=default) / Carbs Burner / Fat Burner and Carbs Burner
- finetune the percentages for each zone
(Advice : do to consume too much carbs per hour, the absolute maximum is 70g/hour)
Installation
- Install the Data Field on your watch by clicking download in the Connect IQ store
- Configure your watch to use the data field:
- Choose the Activity Profile for which you wish to install this data field for (eg Running)
- Choose Activity Settings
- Choose Data Screens
- Choose “Screen 1” (or another screen)
- Choose field 1 (or any of the other fields)
- Choose “Connect IQ”
- Select “Fat Burner” from the list
The sequence on how to do the above things is a little bit different on each watch (you can find the buttons to press in the user manual of your device in the section “Customizing the data screens)”
Configuration
You can configure how the app behaves in the application settings (via Garmin Express or Garmin Connect Mobile)

hi,
can i see the fat burn in percentage and not g?
currently only a value in g is exposed.
Hi, is there any way to increase the size of the font on screen? Thank you.
This data field is of the simple data field type where the font is chosen by the Garmin Software, so no not possible. However, I’ve also integrated the Fat Burner logic in my “All In One” data field, perhaps the font in that app is better readable for you?
hi, I like to think I am a data geek/freak but I can’t tell what this app does for me or how to personalize it. Is there a place I can read more about it?

Could you explain why there are 5 zones? What do I have to know to configure it? I have studied the maximum fat oxidation is at 60-70 % of my FC Max.
The 5 zones correspond to the 5 heart rate zones which you have in Garmin Connect. (So to get your numbers, see your zones on the Garmin Connect web site)
Ok, then I have to put the 80 % (that you put in the second one) on the third zone because it is the 60-70 % of my FC Max. Is it ok?
Sorry, now I understand you. I have this %: https://ibb.co/8zHbM87
Could you help what % I have to put in your app now?
You can either leave it at the defaults that the app presents (I use it that way) or if you think the fat burn or carbs burn in a certain zone should be adjusted you can tweak it to your liking. For example if you want max fat oxidation at 60% you’d have to put the value to 1 for zone 2.
Thank you for taking the initiative to create this app!
Some labs offer performance diagnostic tests that give you an exact burn rate of carbs and fat as a function of power output (which one could relate to heart rate). This carb:fat ratio depends on your individual metabolic profile and can change a bit with time depending on the type of training you do. Nonetheless, the default estimates already give approximate values that should work well enough.
For athletes with a power meter (mostly cyclists, but nowadays also runners) it would be really great to add the option in the app to define the carb:fat ratios using power zones instead of heart rate. The burned calories can be more accurately calculated using power. Moreover, if one has personalized carb & fat burn rates (from test mentioned above) it could become accurate enough to really fine-tune fueling.
Thanks for creating this neat app.
How do you have total burnt grains of fat/carbs in the file instead of graph? Is it possible to have both?
Thanks for your reply Peter.
I think the total fat/carbs also shows in the summary statistics
Can I see details from my walk earlier today either in Garmin connect or somewhere else?
if you indicate in the app settings to record fat / record carbs then this data is written to the fit file and as a result visible in the activity summary on Garmin Connect Web.
I see that is possible change Kcal/g for fat and for carbs, but is not possibile put value in decimals, so I can not write 9.14Kcal/g for fat and 3.81 for carbs: why?
I’m not sure I understand, it’s per default with values after the decimal.
I have a question about this. I’m on keto, and i been on keto for more than 6 months where i already reached the fat-adaptation stage of solely burning fat for fuel. If im on a 0 carb diet, and all am i burning is fat/ketones, especially after fasting and running on an empty stomach, then do i count the “carbs burned” in this app as fat as well? Because i am no longer burning any carbs or have glycogen stores left.
