The logic of denying treatment to smokers and people deemed obese goes against the underpinning ethos and point of the NHS. Aside from making little sense — why not exclude people who participate in risky sports, or drivers with a record of speeding or other moving violations. Or how about denying treatment to people with terminal conditions — it could be said they will die anyway so why waste the money? Take your pick. Life is risky. People have issues. And NHS treatment should not be parsed out on grounds of (some peoples) moral intolerance, body intolerance or preexisting medical problems.
