I think we should also put culture/group back into the equation.
Instead of being bored on a couch watching channels, spend time with people gathering fruits and making your own meals as a fun thing to do. It may first feel dull at first but I think it's a good blend of social, physical and nutritional health.
Points 1 and 2 are certainly controversial for endurance athletes doing intense workouts or races. Those are a small fraction of the population, but the point is there are hardly any universal guidelines.
1. Sugar bad
2. Eat less
3. Find good eating-habits that you can maintain indefinitely
Point three is where people will naturally have different outlooks. I don't read that as disagreement as much as diversity.
