Garmin has already started down this path, although they have a lot of room for growth.
Currently my company uses the vivofits as wellness programs where participation is optional. But so much participation is expected out of the employee to minimize health care costs. An employee can fudge what they do, take a bunch of tests and save about $100 a month on their health insurance. Otherwise they don't have to do much at all and pay the extra. Now there are ways to get out of the extra work, such as if your blood work shows your numbers are good, then great. You pretty much don't have to do anything.
There are aspects that I don't like about this, but being in the Midwest and having to pay for Billy Bob and his second helping of gravy covered fries, three 20oz Mountain Dews, and three cheeseburgers during a 20 minute lunch break; I find taking care of myself and a little encouragement isn't a bad thing.
My company is self-insured, so any tubby decides to clog his arteries and require a septuple bypass, some how that seems to affect the profit sharing.
I guess that all depends on what you want to get out of life, but since I started this wellness kick this last year, I think I would rather spend the time and effort slimming down and improve my quality of life a bit rather than require my own personal morning noon and night pillbox for every day.
