That's great, I'm trying to do that too, keep junk food out of the house mostly. If it's in the house I always end up eating it even if I'm trying not to, if it's not in the house in the first place then I won't go out of my way to a store just to buy it.

I got to a really good place with this a few years ago, where I just rarely ever bought sugary junk food, I was a much better weight/in better shape then. I would walk in the grocery store and not even look at that stuff, I would go in, get what's on my list and get out. It lasted for a couple years. It gets a lot easier over time, but I went back to my old habits slowly due to various reasons

In general it's easier to resist buying it in the first place for me than it is to resist eating it if it's already here
