The major issue with this paper and this protocol is that it is not reproducible.
As the protocol is not accessible / published, we cannot determine how the difference in the set of measures between participants were determined and as such no researcher can independently replicate this study.
This is why those licensed diet / lifestyle change are never science: by definition. Even if they actually produce the desired outcome, all the research is produced either by the creator or by researchers that entered a license agreement and thus have conflicting interests and bias.
