Moreover, said study, which was published in the peer-reviewed scientific journal BioMed Research International, recently (Pruimboom. 2016), doesn't even have the world "paleo" in title of full-text and could still be called "the true paleo" study. It does, after all, revolve around a 10-day mimic of a "hunter-gatherer lifestyle" and its favorable effects on anthropometrics and clinical chemical indices such as the reductions in insulin, triglycerides, HDL, elevated liver health markers and other indices that are usually far from being optimal in the average student, scientist, physician, and other health professionals who participated in the study at hand.
As the researchers point all, all subjects (n=10, n=32 and n=11) "were interested to experience the impact of ancient lifestyle on their own health and well-being and therefore jointly decided to engage in this study" (Pruimboom). In that, the term "this study" refers to three separate 10-day trips through the Spanish Pyrenees during the summers of 2011 (𝑛 = 10), 2012 (𝑛 = 32), and 2013 (𝑛 = 11), on which ...
"[t]he participants lived outdoors and walked from one watersource to another. Food was provided by the organization and with help of forest-guards from official institutes of the Catalan county. Food intake was planned before the trip, based on the average daily food intake by the traditionally living Hadzabe people in Tanzania. The use of mobile phones or other electronic devices was not allowed" (Pruimboom. 2016)It is obviously debatable, if "mayonnaise" is a paleo food (not sure if they made it themselves) and how "paleo" the rest of the subjects' diet which may have been designed to mimic the macros, but probably not the foods of the Hadzabe (see Figure 1, tabular overview on the left) actually was.
