> Best option is to avoid any so you don’t have to count
This is why one of the best ways to lose weight is to just keep a food diary / count calories. You don't need any special / fad diet, just the act of trying to keep a note of everything you eat will cause you to stop and think, "I don't need to eat this".
This is what happened to me when I needed to lose weight. The act of counting calories more or less completely revamped my diet in a positive way.
Turned out I was also stupidly deficient on protein day to day.
Consciouss eating.
One can (and should) extend that concept to anything. Be conscious about what you do. Then you likely know, if you are not doing good - and can change it.
Replace your diet fad with a journaling fad.
(this tip works with finances too)
You can give yourself an ability akin to time travel by writing things down first.
If I write down the calories afterwards, I get the "oh, I shouldn't have done that" feeling at times. I'd like a little time travel button that takes me back to before I did, and let me adjust my behaviour and run through the situation again. If I write it down first I get to have the "oh, that's not worth it" feeling up front and decide to do something else.
This made a big difference for me, both lowering what I was eating and making me happier about the choices I made.
