This seems like an ad for "virta health." Which itself seems to be a pile of supplements, a scale, and a Keto Diet plan.

Keto Diets (and intermittent fasting) have been shown to help "reverse" type-2 diabetes, since it moves people out of the medical criteria for the disease. But if the original lifestyle returned that individual may become classified as a type-2 diabetic again.

The article-writer states he is an investor in Virta Health because he actually believes their approach will work to reduce T2D at scale.

[Someone1234]

He has to believe that because he is financially vested on the outcome.

On the other hand, why would he financially invest in something that he didn't think would work; why would he put his reputation as a researcher on the line to back it?

Depends what the rate of return is.
