This is some solid advice and stuff I follow. Diets don't work, you need to make gradual lifestyle choices instead (like limiting soft drinks).
The one advice I don't agree with is on fruits. People need sugar/carbs for energy, but obv in our culture we get too much of it from crap. If you limit the crap you should never say "hmmm I guess I shouldn't eat this apple because it has too much sugar", you will be missing out on a lot of nutrients. Unless you are grossly obese this advice is bunk.
