Here's an article on weight loss using cocoa.
http://www.progressivehealth.com/using-cocoa-for-weight-loss.htm

The relevant section is:

"The 3 cocoa extracts are Lavado, regular and Dutch-processed cocoa extracts.

Of the three cocoa variants, Lavado cocoa undergoes the least processing. To prepare Lavado cocoa, the beans are washed and not fermented. Therefore, it has the highest concentration of polyphenols and flavanols.

On the other hand, Dutch-processed cocoa has the lowest concentration of these flavonoids. During preparation, it undergoes alkalization which degrades some of the polyphenols in the cocoa beans.

In this study, Lavado cocoa extract was the most powerful inhibitor of the 3 enzymes and Dutch-processed cocoa was the least inhibitor. The study showed that cocoa extracts can inhibit the selected digestive enzymes in vitro, and by this means may also contribute to weight loss."

I think that means that the best kind - Lavado -is also the cheap stuff. i.e., Nestles, Hershey's, etc.
