Welcome back Robbo80, I hope you get back in to fasting easily. If I understand correctly the warrior diet is an extreme form of time restricted eating. On fast days I eat just the evening meal with one or two pieces of fruit and cups of tea to get me through the day, but I wouldn’t want that level of restriction every day.

It’s helpful to have some strategies for the FDs to make them a little easier.
Plan the meals ahead and make sure food is ready to prep easily or even just reheat.
Choose filling but low calorie meals – that means padding meals out with lots of veg. A pot of hearty veggie soup like a minestrone or scotch broth can work really well. They are filling, warming and generally keep you feeling satisfied for a while.
Drink plenty of water as it can deter your appetite for a little while.

You said you haven’t succeeded eating 3 meals a day. I wasn’t sure if you meant that you no longer wanted 3 meals, or that snacking was the issue. If you don’t want 3 meals, you don’t have to eat them. I never eat breakfast because I’m not hungry first thing in the morning. I usually eat a late brunch and dinner because that matches my appetite. If it’s snacking that’s the issue then it’s an issue many of us have, me included. On the NFDs I plan healthy snacks, mostly fresh fruit or a handful of nuts. When the snacking gets too bad you need to distract yourself with a task or a walk – something that you can focus on that takes you away from the food source. Something I use on a FD if I’m craving something I can’t eat that day is “Yes, you can have it tomorrow”. Our subconscious doesn’t like NO, so I find this little mantra works better for me. Of course when tomorrow comes around and it’s a NFD the obsession to eat that particular thing has usually vanished. You can also adapt this mantra to delay snacks until meal time by saying “Yes, you can have it with lunch/dinner”.

Good luck Robbo
