Well the things to remember is
1) 1 study isn't proof
2) This was a fairly small short term study with those that have diabetes
I also thought there had been multiple studies showing that multiple meals vs 3 didn't matter but I could be wrong. There have also been other studies in the past that showed greater weight loss with one diet in the beginning but in the long term, other diets performed better. Who knows if this plan would even out in the long term or has a lower compliance level in the long term.
Overall, I still think it is what works for you. You may try 2 meals/day and think it works well but if it doesn't, don't think that you've failed.
You can't out-exercise poor eating habits.
