I agree that for most people a regular diet is probably just fine, and the right choice. However, it takes very little looking to see that there is interest in keto in the UK, for example: https://www.bhf.org.uk/informationsupport/heart-matters-magazine/nutrition/ask-the-expert/keto-diet-weight-loss https://www.bhf.org.uk/informationsupport/heart-matters-maga... The vast, vast majority of people I know in real life (in the US, in case it is not obvious) have exactly zero interest in any kind of extreme diet. The ones that do tend to be louder, which you may mistake as implying it is a commonly held belief.
