Myfitnesspal/strava/muse/Fitbit

I use all of these and have lost over 30lbs since my days as an SVP at Blackberry.

Strava captures my daily commute to work.
Fitbit motivates me to climb the four floors to my office multiple times a day.
muse gets me focused with helping me stay motivated to meditate and deal with cravings.
Myfitnesspal keeps track of my calory intake, my calory burn and keeps tracks of my weight and nutritional targets.
