My diet is a no processed food diet. And that means as close to zero processed foods as possible, no purchased snacks or junk food unless the circumstances are extreme. I almost always buy foods that are at a very low level of processing - for me that means fruits, veggies, nuts, grains, milk, cheese, eggs, meat, fish, all are okay. Single ingredient canned or frozen foods are okay. It's amazing how few of the foods in the grocery store pass this criteria. You might call it a "buy ingredients" diet.

And the "no processed foods" is a strict limit for me, it's not a "processed foods in moderation is fine". I find that moderation is far more difficult. Having a line in the sand that you don't cross is much, much easier than one would think.

This means cooking a lot. I do go out to restaurants occasionally, I guess technically that's processed foods, but mostly it's cooking at home.

I don't try to buy organic. I honestly think organic is a bit of a scam.

I do have treats and "junk food". The thing is, I make all of them. I bake my own cookies, etc. I'm under no illusion that my snacks are healthier than purchased snacks. They probably are, but the real benefit is that it takes effort and time. You can also get into some interesting food related hobbies. For instance, candy making, and making fancy popsicles (which are lots easier than ice cream and just as good, and also limited in portion).

I grind my own wheat. It's quite fun, and pre-ground whole wheat flour goes bad quickly, whereas the actual wheat kernels keep forever. I bake my own bread, because it's easy and tasty, and you get picky once you've had your own bread.

It's a process. The first step for me was to say an absolute no to french fries, which I always had problems with. Next was - no fried foods (unless I fry it myself). Now I'm at "no processed foods", and it works very well for me.

The other thing I do that's a little different is extended water fasting. Extended, for me, is 3 days or so. I never got further than 4. There are some very powerful, astonishing benefits, even if you're not trying to lose weight. You will lose weight, of course, but it'll come back quickly unless you're trying to keep it off, which means changing habits.
