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)
