Well yes, it is personal. As such no dietary advice is worth more than the experiments one conducts on themself, to see how one responds specifically. If something isn't working, then sure, look to the science for potential solutions and try them out. Nothing, however is guaranteed. If you're not getting the results you're hoping for, move on. Conversely, if it ain't broke, don't fix it, even if someone out there is telling you that you're doing it wrong. For example I have a weakness for sugar cereal. I know it's on the bad list of sweet, ultraprocessed foods. I also know that, as a pre-workout meal, I perform great after crushing a half-box of Trix or Captain Crunch.
