If you mean "health insurance providers", then we already have that in Switzerland.
My anecdata is when an obese acquaintance walked in to the (for profit) insurance company and asked for "extra" service; the insurer is not obliged to offer that to everyone (whereas there is also a compulsory insurance), simply based on the looks, I guess.
I kinda loathe these insurance providers, however, I can't disagree with some of their policies (lack of exercise induced obesity and smoking is a big no in my book). So indeed, using the "walk enough" information is probably the future, OTOH countries without similar systems (UK, and Eastern Europe comes to my mind) have collapsing public healthcare where they can't filter out self destructing lifestyle, everyone bears the responsibility.
