I can imagine smaller efficient cars becoming the norm. If we also make the atmosphere actual poison, this may make a full comeback.
Garmin lets you set your calories per day, which you can get measured at certained locations (RMR: resting metabolic rate). Garmin instinct is a great tracker, and if you're looking for something a bit more fancy, the Fenix is a great series, too.
Edit: I can't find the settings for setting daily calorie burn, but my calorie tracking does line up with my RMR pretty well.
