that's exactly it! there's a point where making a change...any way, any how...is the most important thing. and getting out of a place of extreme unhealthiness as quickly as possible trumps learning to eat in a sustainable and optimal manner (that's important too but can come later).

When I first began losing weight I had to lose 70lbs before I could walk one mile. And I mean before I could accomplish a mile walk. It was too taxing to do regularly. It took 2 days in bed to recover from the effort.

I was so unhealthy that losing one pound per week would have kept me at a dangerous weight for YEARS. When you have 20lbs to lose a pound a week makes sense. When you have more than 200lbs to lose it doesn't make as much sense.
