Is it really great #scicomm? The article references one study as follows: "personalized nutrition based on genetics, research has shown, is more effective in reaching long-term weight-loss goals." Let's take a look at the study... https://twitter.com/PhD_Leigh/status/1380582305882857473
The study (linked below) doesn't even report on weight loss! This is a bit of a problem for a couple of reasons. First, the public now thinks that there are effective personalized approaches to to long-term weight loss based on genetics. https://nutrition.bmj.com/content/early/2020/05/21/bmjnph-2020-000073
The second problem is the study itself. The registry for says that the primary outcome was differences in % body fat between groups. This was not reported in the paper which pretends that the main outcome was change in self-reported dietary fat! Hmm. https://clinicaltrials.gov/ct2/show/NCT03015012
I finally found the study publication (not linked in news article) that actually reported the primary outcome of the trial. It ended up showing that the personalized nutrigenomic intervention had no significant effect on long-term body fat change at 1 yr https://onlinelibrary.wiley.com/doi/10.1002/oby.22880
Apparently, another paper from this trial reports some odd effects of the personalized nutrigenomic intervention on physical activity. Stop the hype! https://twitter.com/DylanMacKayPhD/status/1380682691285245953?s=20
