Data Field: Fat Burner

The Fat Burner is a simple datafield which fulfills a user request from Susun.

Connect IQ App Store Link: https://apps.garmin.com/en-US/apps/7...2-20971e02898b

This field calculates the fat calories burned depending on heart rate zone & calories:

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 (Advice : do to consume too much carbs per hour, the absolute maximum is 70g/hour)

During your run it looks like this:

On Garmin Connect you can afterwards consult how many fat and carbs you have burned (if you have indicated in the settings to record it):

how to activate the app on your watch?
(it might be slightly different on your watch, this is how to do it on a fr735xt: from watch face - click start - choose an activity profile (eg Run) - hit down button - activity settings - click start - data screens - click start - screen 1 - click down button - field 1 - click start - hit down until you're over connect iq - hit down until you' re over fat burner - click start )

Advice by Susun:
For the users that want more accuracy, better if you use Karvonen formula using Garmin profile settings.
Karvonen method is more precise because is related to VO2 max for the most of people so I recommend it.

Go to your user profile and then HR zones configuration, choose %HRR and put your HR-Rest and set the zones as this:

Z1: 50-65
Z2: 65-75
Z3: 75-85
Z4: 85-95
Z5: 95-100(HR Max)

Hi Pete,
Thanks for your response and sorry for not opening the second activity, totally forgot, but now it is public.

LeoPac72 I'm in contact with Garmin about this bug and they have requested the fit files from these activities. Could you download the fit files from these 2 activities (choose download original) and either attach them to a post or email them to me? Thanks. :)

hi Pete, Here are both files for the activities:

Please let me know if you need something else.

Regards!! Leo

you have updated the app, what's the changelog ?

peterdedecker over 6 years ago

The app got auto updated (this is to add support for new devices). When i make changes i post the changelog in this thread.

Hello,

Im the guy that suggested to display fat/carbs per hour in the app review section. So i m tranfering our discussion here.
What im saying is basically to do it in a simillar way as Flexirunner or Dozen run do the energy expanditure graph where they display how much calories you would burn per hour during your run.

peterdedecker over 6 years ago

Without a formula to transform the fat value in grams to a fat calories/hour figure I won't add it to my to do list. With I might add it to the list as alternative display.
How does the value in grams correspond to the calories/hour figure. Is the sum of the fat and carbs calories in grams considered to be 100% of the calories?

Hi again,

Sorry if i wasn't clear enough.
My suggestion is not about fat calories or carb calories.
From my understanding what im suggesting should not require any new formulas. The data that you already have should be enough with just an addition of a simple calculation.

For example
In the graph bellow you can see that i burned 0.73g of fat during the first minute of my run. With a simple calculation you can get how many grams of fat/per hour im burning during that 1 minute period.

If i burned 0,73g in 1 minute how much fat would i burn in 60 minutes? 0.73 * 60 = 43.8
So basically during that 1 minute period i was burning 43.8g of fat per hour. Also for a more detailed graph i suppose that you can simply lower the periods in the calculations from 1 minute to 1 second.

Ok, so you want to have the rule of three applied to record the total value in grams / time period to be total value in grams / hour. Do you want the base for this time period to be a fixed slot of eg 1 minute recalculated to an hour period or the total time passed so far recalculated to an hour period?

I suppose that calculating with total time passed so far would give a much more detailed/meaningful graph.Basicaly, wouldnt that be the same as calculating on a fixed 1 second slot?
The point of all this would be to be able to see through the graph at which point in your run you where burning the most fat or carbs per hour and potencially try to duplicate this on your next runs based on your goal.
The fat-carbs/hour or avg fat-carbs/hour could also be very usefull to be displayed in the datafield while in an activity as well.

peterdedecker over 6 years ago

No.
It would be a totally different graph if you take in the total time versus timed slots, eg in the case of interval session or walk/run sessions the graph over total time wouldn't be so meaningful.

The point of all this would be to be able to see through the graph at which point in your run you where burning the most fat or carbs per hour and potencially try to duplicate this on your next runs based on your goal.

Don't you see this best the way it is now?
The advantage of the current presentation is that you can pick your own time slots and make the difference between the points.
