I can't be bothered to read the article, but I recently discovered I can lose weight fairly easily by, wait for it... just eating a little bit less of everything I already eat. Other than that, the only conscious change was to sometimes substitute a chocolate snack with an apple.
There has to be something like Dunning–Kruger effect but for situation where you try to improve something, learn a convoluted (and rarely scientifically confirmed) solution, apply it for like a month only to then crash back to the start and realise there is no workaround to eating less calories for example
Instead of accepting that big, sustainable changes are not achieved through shortcuts, my brain needed some convoluted or painful solutions (like extended water fasting) which also makes you think like you "cracked the code" and you are better than your mum who told you to just not eat sugar
