Saying a particular study is junk out of thin air just because it does not suit your perspectives as you tend to rely on them (in this case UPF), is pretty disrespectful to the thousands of doctors and scientists who have said the same. It's like asking to reason with an alcoholic or a smoker on why they are bad for you.
UPF, obesity, or lack of nutrition - all of these are not mutually exclusive - as the study clearly stated that UPF increase the risks - not the end-all-be-all reason.
