Skimming through it you can tell there are major problems with the study design, data, and conclusions. The data comes from a mix of self-reported and investigator measurements. Should have only been done by the investigators, but some datapoints clearly show signs of bad self-reporting, should not have been used as baseline. Nearly every measurement goes up, highly unlikely to be real biological data. All 14 subjects were friends, never seen that one before in a paper. Finally, extremely weak attempt at explaining a mechanism or explaining their hypothesis for why they explored this in the first place.
