I didn't. I was talking about a media hyped weight-losing strategy called keto, not about genetic health issues. Keto is nothing but a good working marketing plan. If you can't eat fruit due to a genetic problem, then of course you shouldn't eat them - and follow a diet that has been customized by a doctor according to your specific situation and needs instead.

I am allergic to avocado which is why I have to avoid them completely. So I fully agree on what you said about preferences. Yet, keto promotes something completely different: it tells people to exessively eat fat and protein, independently from their personal situation or constitution. No human being in the world is able to process such amount of fat ever, which is why so many are suffering health issues after such a diet. They start having diabetes, increased blood presure or even suffer a cirrhosis of the liver.

Talk to a scientist or a doctor who's not paid by those gurus, and you'll get a valid response yourself if you don't trust mine :-) Or read the comment from @honeycup-waters in this thread...
