Our intervention diets were well matched as were our items in the test meals. A secondary aim was to examine food choice of either UPF or MPF items. More info on the foods is in our previous paper. doi.org/10.1016/j.cc...

We also tested eating in the absence of hunger, a metric that predicts later weight gain in young people. Again the adolescents ate more after the UPF diet than the nonUPF diet. They weren’t any hungrier before either meal and controlling for hunger or weight variation didn’t change our results.

We were of course inspired by @kevinh-phd.bsky.social but also asked what happens to energy intake if you hold weight stable and test younger people. We found that overall w/o weight gain UPF consumption did not increase energy intake. But if you examined our data by age younger people ate more.

@davybrenda.bsky.social and I’s UPF RCT is finally published! We tested the effects of a eucaloric UPF vs no UPF diet on energy intake in young people. Our age subgroup analysis found adolescents ate more in a buffet meal after the UPF diet. 🧵🧪 onlinelibrary.wiley.com/doi/10.1002/...
