Hmm, I would think you could use any meal plan and eat all meals at the same time in the window. I would probably suggest eating the protein and veggies first so you're less likely to overeat on carbs.
At the same time I probably wouldn't want to eat 3 separate meals right after each other. If you prefer one larger meal then I doubt you could follow the meal plans exactly as they are. You would want to build one meal with all of the necessary macros and nutrients, you could definitely base it off the provided meal plans and adjust as you go but it would depend on your experience with nutrition in general. If it's all pretty new to you it's probably best to find a plan/meals built around intermittent fasting first until you feel more comfortable.
Not sure if that helped
