It counts as if all kJ/calories measured are all fat and ALSO (which is impossible) are all carbs. When you do: (fat gr x 9kJ/cal)+(carb gr x 4Kcal/kJ)= the result will not match with the amout of kJ you burned...and it's double...

Check your math. You'll need to properly account for the correct kJ/g for fat and for carb and also account for gross efficiency.

Sorry for your trouble. You will require a power meter configured on your Fenix. The app uses power data to estimate fat and carb utliization.

Absolutely useful option, and honestly, I use it to help me with my 'Polarized' Training. Everyone knows how to go hard - it's going EASY that takes "work". this little gadget uses known metrics to help you understand just what is going on, gram-wise, between your power output and your stored energy systems. For Base training and Ultra-Marathon cycling, this is a MUST-HAVE.
