I've been fasting here and there and I'm down from 130Kg to 98Kg in about 5 months. Apparently your body handles that sense of deficiency better if you fast vs multiple small meals. Something about that large meal letting you experience the "I'm so full" feeling.
There's a study in the NEJM where they tested 3 meals a day vs one. The participants ended up at the same weight at the end, but with smaller waists and less belly fat for one meal a day.
It's all interesting albeit frustrating stuff...

I might be remembering the results wrong as I can't find the details in that study, I'm going off this video mainly https://www.youtube.com/watch?v=thgVz3837l0
If I'm wrong about the results it seems the other benefits make it worthwhile anyway, preventing diabetes etc
