Hello @rawadventuress
I think the three that you've outlined can be applied to anything in life, not just eating habits. I have done all three of these at various times and the third one is probably the most damaging because with that we also feel like a failure and it can become a pattern.
Many people beat themselves up a lot about things that they want to do for their own betterment but change takes time and trying to change too many things at once can actually backfire (I wrote a post on this a few days ago).
