There are not really good or bad way to do it, I find 16:8 to be more of a 2.5 meal “diet”, the .5 being a snack, be it at the start middle or end doesn’t really matter. I would count a smoothie as a snack.
Own personal view here :16:8=2.5 meals, 18:6=2, 20:4=1.5 and 23:1 (or omad)=1
Note than when meals and snacks are closer together, they also have a tendency to be smaller, since the are still food from the last time you ate in there. Which can be all good if you try to eat less overall.
Small steps.
Good job so far, keep going!
Imo…you do whatever works for you. Remember that the more times eating, the more insulin spikes. But that is if no real concern if the pattern you are using is a best practice for you to keep generally in line with.
