    As someone in the same boat using the same app for calorie tracking, I just wanted to share something that may be of use to you: the calorie expended/burnt estimation that MyFitnessPal and Strava estimates is WAY too high. Once I started using the heart rate monitor with my Garmin 920xt, I found the calorie estimation to be 15-30% less. After reasearching it, it turns out this “newer” technology Garmin uses called Firstbeat is much more accurate (in the range of 90%). I think by seeing the pics you’ve shown that you have a Fenix 3 and it has the same technology when you use the heart rate monitor. Anyhow, this isn’t meant to rain on your parade but more as something to help you so you can lose weight easier. If you calorie burnt estimations are too high, you’ll find the weight staying on–which happened to me and it really annoyed me.

      hey avery,

      yeah i’ve noticed that too with strava and myfitnesspal.

      i’ve been eating roughly 4,000 calories a day and running 50 miles a week for some time now and have maintained the weight of 203lbs for too long. i think 3,500 a day for me would lead to a very small loss if i was running those same distances. it’s tough to get the details right though. still guessing.
