I added my two cents on this here earlier today. In short, there’s a limit to what I can say as the journal is one my university doesn’t subscribe to, but a) it’s hard identify causal relationships from this kind of data and b) I’d be extremely surprised if IF with a healthy diet was anywhere near as dangerous as being overweight.
This was t a study, it’s looking at data from a prior study. It doesn’t confine the participants to just those skipping meals as part of IF, but anyone who was.
Ie, if you are doing IF and strategically limiting your eating window to lose weight, and eating proper that is extremely different from “I m poor and only eat one meal a day I buy from 7-11”
Skipping meals doesn’t always mean IF. Someone can ‘skip’ breakfast but still snack throughout the day; there’s no indication that they were actually fasting. Skipping meals like that is indeed unhealthy and tends to lead to more snacking and binge eating later and in that context, this study makes more sense. I feel like extrapolating that and stretching it to apply to intermittent fasting is a bit of a reach and I’d take this study with a grain of salt.
