"Your theory that losing slower would be more sustainable than losing faster is interesting, but do you have any actual evidence for it?"
I think losing weight quickly for a short period of time (4-6 weeks) works very well (e.g. V-Diet). I also think losing weight slowly over the long term (max 1 pound per month) also works well.
I think most people try somewhere in the middle of the two extremes and it just doesn't work. Trying to lose weight quickly for an extended period just doesn't work for all but the most motivated people.
For evidence in support of losing weight slowly and almost effortlessly take a look at the book Mindless Eating. It covers a lot of interesting research.
