From what I've read, it is better to get calcium from milk, vegetables like Spinach, Kale, Okra, Collards, or Soy or White beans, or some fish rather CaCO3. The Mayo clinic suggests taking CaCO3 with food, because stomach acid helps with the absorption:

The thing that worries me most about this diet is that, while in some ways it may be of great benefit in energy, etc., some of the side effects may not be seen for months, years, or perhaps a few decades.
It is an interesting experiment, but I think it would be a good idea if it were controlled and monitored by a doctor.
Also he said, "This is one case and it's only been a month". I ate almonds, peanuts, cheese, meat, and veggies for a few months, lost 15 lbs. But, since I've gained it all back and then some. One month at a new diet something hardly makes one an expert.
