I think it's fair to say that we don't have to do something just because there's a plausible mechanism for a benefit. If there are clear and obvious health benefits that are far beyond what you see with a regular calorically restricted diet, I haven't heard them well explained.
The points listed there include heart health and the prevention of diabetes and obesity, which are very clearly things traditional caloric restriction also help with. For the other claims I don't see any comparison with traditional caloric restriction (I can't access the source paper).
I think we are talking past each other actually - I read your question "how did it make you healthier?" as in "how did it act to make you healthier?" and now I think you were saying "how did you determine it made you healthier?". Ambiguity of English strikes again...
