MyFitnessPal ignores 3rd party app calorie calcs locoblade — Jan 12, 2018 11:54AM PST

Does MFP always ignore the calorie count from linked apps feeding it information and blindly work it out for itself or should it include the data from the partner app meaning I have an issue?

In my situation I've linked Strava to transfer stationary Wattbike rides that I do at the gym. The Wattbike knows my weight, heart rate and actual wattage output so will be calculating calorie burn quite accurately. When the Wattbike updates Strava the calorie count is added accurately but following a MFP sync with Strava, the calorie count is usually about 20% less in MFP presumably because it's making assumptions on effort exerted rather than taking the actual data from Strava?

Having searched the forums here I see it's not the first time this anomaly has been raised and it seems an overight that it wouldnt have been fixed as there's lots of exercise recording apps and connected devices available now with the live inputs available to determine calorie count far more accurately than a generic guesstimate based on exercise time and weight alone so it's annoying that every time I do a ride I have to go in and manually correct MyFitnessPal's data.

Thank you for taking the time to contact us. Occasionally there can be differences between the calories burned on an activity as calculated by Strava and as reported on MyFitnessPal for Strava recorded activities. This typically happens during Strava’s peak traffic hours and is a result in a delay in the elevation lookup process for the Strava activity. Because elevation is a key variable to calculating calorie burn, if Strava is delayed in obtaining elevation data, Strava can’t send the calculated calorie burn to MyFitnessPal so the calorie burn is an estimation based on some general activity parameters.

All the best,

Hi Bruce, thanks for the response but that's not the problem here as there's obviously no elevation changes on an exercise bike and Strava isn't recording my Wattbike ride "live" anyway. At the end of the session the Wattbike updates Strava with ride data including calculated calorie burn which Strava records unchanged so this should then sync to MFP, but then when Strava and MFP sync, MFP seems to ignore the Strava information and calculates calories independently discarding the information stored in Strava. This happens on every workout without fail and MFP is always about 20% lower than the Wattbike calorie calculation stored in Strava.

Thanks for getting back to us. Can you try relinking Strava and MyFitnessPal and see if that helps with the sync?
