Why Does My Forerunner 245 Show Zero Calories Burned?
Garmin is aware of an issue where the Forerunner 245 will display zero calories burned when using a Connect IQ watch face. We've released a beta software update that has corrected this issue: Forerunner 245 beta software update
If you wish to wait for a production build of the software update, calorie information can also be viewed from the My Day widget on the watch. Otherwise a temporary workaround is to choose a preinstalled watch face and customize it to display calories.
Hold the UP button
Select Watch Face
Select the UP or DOWN button to preview and select a default Watch Face
Select START then Customize
Select Data then use the UP or DOWN button to scroll through and select calories as a data field.
