Identify a cheaper way of getting people to change lifestyle that is actually possible to get agreement on and that actually works, and you'd be showered with money.

Trying to get support for changes to what food is available etc. may well be better in the long term, but in the short term you're doing the equivalent of asking a bunch of addicts (me included) to voluntarily vote to banish our dealers.

Many of us will, but the measures will remain weak enough that we'll still find ways of satisfying the addictions anyway.
