Rapid weight loss is better than slow?

There's so many conflicting ideas about weight loss, and every time
something becomes the accepted truth, another conflicting story comes
out. I read an article in the paper recently that claimed rapid weight
loss is better than slow -- and it's confirmed on several online articles
as well. But the conventional wisdom has always been slow and steady
wins the race -- especially if you want to keep it off. What to believe
now?
I must say I agree with the rationale in the story that when weight loss
is too slow, you lose motivation. But is it healthy to lose weight
rapidly? I mean -- what would you have to do to keep it coming off at a
rapid pace -- restrict calories to extreme levels, or just work out
heaps more? It's no wonder we struggle -- even the experts can't
agree.
