This was from the Food4Me study The basic advice group got what I would say is very similar to a standard dietetics consult So either spend 100s or 1,000s on specialized pathology and genetic testing, or see a dietitian once Tough choicepic.twitter.com/qzvSGMTvOm

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)

It's actually amazing - they spent massive amounts of time (and presumably, money) developing complex decision trees for 5 genetic/diet interactions and found that it made 0 difference compared to the sort of basic advice dietitians give every day

So maybe when someone claims that following nutrition recommendations does not make him/her lose weight, improve health or something else and it is because they are not personalized to his/her specific genes, it is not true.
