The problem isn't the data, it's the services, which for the most part are geared towards motivating and entertaining you, not helping you interpret your data.
One reason for this is that the human body is too complex (and the data too incomplete) for simplistic advice like "walk x steps per day to reach weight y".
You're also unlikely to discover a novel correlation that can be used to lose weight (and write a book and get rich)... But what you can do is use your data to determine which known solutions are working for you, and which are not (e.g. do I really sleep better when going to bed before midnight, all else being equal?).
I'm eager to see how exist.io handles all of this! (I run another service in this space, zenobase.com)
