This is what is working for me. I started out doing 16:8 2MAD with some longer fasts added in. I found that I mainly lost weight during the extended fasts and maintained doing 16:8. So I kept doing the longer fasts until I reached my goal weight. Since then I have been doing 16:8. 6’1M started at 270lb, GW 210lb. Reached my GW in 4.5mo, have maintained 205-210 range for 6mo. My 16:8 is 2 large meals, sit down and eat for 30-60min, but I basically never snack outside of meal times. I love it.
