OK, this is a chart showing obesity's progression (worsening) in the U.S. from 1990 to 1998 to 2007 (credit 15th edn of Basic Pharmacology for Nurses):
I'm in Canada, and I believe we're lagging the US in obesity by perhaps 10-15 years, and I'm guessing similarly for you folks in the UK -- but clearly, we're all trending in this direction so the writing's on the wall.
Is there any hope of stemming this obesity tide and the predictably horrific consequences on our healthcare systems?

Problem with those three approaches is that the budget for the opposition is gigantic (we'd never be able to match, let alone, outspend the convenience / processed / junk food industries), and 'screen time' is fun -- who wants to give up fun? (especially when we're less limited just now to safe alternative activities)
