How is that actually supposed to work, though? Does the Apple Watch make people walk so much they gain weight?
As pointed out elsewhere you're off-topic. You're confusing ResearchKit with HealthKit and/or the Health app. But yes, one of the health app's functions is to encourage more activity such as walking, by feeding back how much activity you've done today against a target you've chosen. It's not a new idea, pedometers let you do this. But it looks to be a good implementation of it.
