Again, I really don't get it. You think cream without loads of added sugar tastes terrible, or you think oil and butter are totally different foods? Anyway, people have been putting oil in coffee since the 1950s as a cream substitute. Don't understand why you're determined to get upset at "the keto people" for something that is, again, way more popular than keto itself.

This is a pretty weird sentiment to me, as high-fat coffee drinks have been extremely popular for decades now. A frappuccino might as well be made with butter, y'all just can't stand it without sugar.

I wouldn't say low-carb diets are pointless. Study after study has shown that if you're going to cut calories from your existing diet, you'll be healthier and less miserable if you cut carbs rather than fat. What's pointless is replacing carbs with fat without lowering your food intake, and expecting health benefits.
