Jim, when you say three kinds of weight loss, are you thinking of three methods? It seems to me that  ‎the three kinds of weight loss can only be fat loss, water loss, and muscle loss, and all real-world weight loss involves all three, in different ratios. 

Carb reduction or fasting start with pronounced water loss, followed by gradual fat loss and a little muscle loss. But there too calories/energy play a role, as does any metabolic idiosyncrasy.

I believe there are three kinds of weight loss. The first comes from taking in more energy than you expend or excrete. We know now that this is not a simple caloric calculus, but I won't get into that in this post. The second is water weight, which is most of the weight you tend to lose when you are eating an equi-caloric Paleo versus standard diet.. And the third is reducing carbohydrates. I believe, other than surgery or accident, that that's the entire universe of possibilities.
