Why?
THere is nothing it does that can't easily be done with the right diet (which you should have to begin with)
By keeping blood sugar levels low, you encourage the body to burn fat stores.... or so I thought

"Lowered plasma insulin levels (on a long-term [re: 24 + hours] basis)
= elevated catecholamine levels
which in turn:
= more fat-cell mobilizing blood flow activity in your adipose tissue
which in turn:
= a rise in blood FFAs which are more likely to be burned as substrate (especially if you are glycogen depleted, which elevates CPT activity in skeletal muscle and FFA oxidation in the liver as well).
(also: less carbs = more calories available in a given deficit for protein consumption, which has all sorts of positive lean-tissue-sparing + FFA-burning effects for our dieter.) "
It seems to make sense to me.
