The other thing that I can't see discussed in the paper is the strong potential for a placebo effect (i.e. people know they're in a study on personalized nutrition, so the ones in the personalized group adhere better to treatment because they think it's more effective)
I mean, the main outcome measures were basically adherence anyway so...maybe people who are told that their diets are being specially personalized just pay more attention to the results?
Also worth noting that in this, the largest trial of personalized nutrition, no benefits were seen for weightloss or energy intake (although that was not a primary outcome measure)
