starvation mode malarky?

[faithstar 3]

I am sure this question/point has been covered many times, however I wanted to see what the main consensus was on the issue of 'starvation mode.' I am undecided as I have heard many different things...I also heard if you exercise too much and take in little calories, it doesn't speed your metabolic rate up either...can anyone shed any light?

Spirited discussion about this going on right now in this thread:

Lots of great information (and I am too lazy to rewrite)
