So I have to think this notion that it is simple matter of calories is at best selective. Maybe for some people, but I reject that claim 100%. When I went on this diet, I was still eating 1500 calories a day, but I was shedding weight so fast that it scared my wife.
Well, most people who diet do not enter the state of ketosis thus the amount of calories consumed should be predictive for their weight gain/loss.

Ketosis is an inefficient metabolic state where energy from fatty acids is partly wasted (acetone) thus caloric requirement for sustained weight becomes higher. I tried to look up exactly what the ratio of energy production is of a normal metabolism vs a ketogenic metabolism, but unfortunately couldn't find it. It would be interesting to know the numbers..
