I simply do not believe that the so-called health side is really composed of people who are solicitous about everyone else's health. I can't prove it, but my intuition is that all the strength on the "health" side of this war comes not from people who really care whether other people are healthy, but from people who don't like having to see fat people. They are concerned about their own aesthetic pleasures, and they think fat is ugly.
That, and being hooked on the thrill of bossing other humans around as if they were things.
