If I'm fiending for late night snacks, it means I should have eaten a proper healthy meal hours before. It's easier to start from 3 proper meals, with fiber and vegetables, and cutting out sugar, and then go from there to skipping meals. If you are still on sugar, low-fiber carbs, and high calorie meals, then it's just going to be really hard to transition to fasting.

To me the transition order is:

Sugar + Simple carbs + High calorie meals -> No sugar + Complex carbs + Fiber + High calorie meals -> Smaller meals + letting yourself get hungry for an hour before you eat -> Skip a meal -> Skip multiple meals

Minimize (if you can) the amount of food you keep in your home. Ensure that what food you keep is healthy.

interesting point, this would also make mindless snacking more difficult

It's not entirely deliberate, more a consequence of my somewhat minimalist approach to life, but I do this and it works. In don't have chips or crackers or sweets or whatever in my home often. Typically specifically for a party or small servings for me. The worst is after a party of it didn't get eaten. But that's not terrible, a day or two of overeating quickly offset by my normal exercise routine and getting back to normal (low) levels of food at home.
