I’ve done this and it tastes pretty good.

Cant provide any sources but, doesnt caffeine bind to fats similar to the way that thc binds to coffee?

There's actually nothing wrong about this. Video is nonsense. Heavy creamers are basically the same thing not whipped yet.

I see people add milk, I see people add cream - is butter that different?

Reminds me of that olive oil coffee Starbucks was selling that caused people to shit their pants.

I used to do this because it was supposedly better than sugary creamers. You're supposed to use a little blender to whip it up though, then it actually tastes super good.

Bullet(proof) coffee is over a decade old already

Wow, I'll try that tomorrow

Edit: I've tried butter coffee twice, and it's actually decent.

My arthritis got fucked watching this video

I completely agree, but there's an exception: weed butter.

I have tried this out because I got a bit obsessed with learning how to make every coffee drink during the pandemic. The way I did it was a double shot of espresso, a decently sized pat of good quality unsalted butter, and a little bit of hot water. The reasoning was that the butter would accentuate the naturally occurring oils of the espresso and lead to a richer crema on the resulting americano which was true. I thought it was actually pretty good that way, but I also love coffee in any form. It also wasn't something I'd go out of my way to drink again. I also imagine this would do some bad things to your intestines if you drank this every day. If you want a delicious buttery coffee, a good quality whole fat milk is a much better option. As for health claims, I think it's kind of insane that anyone says drinking literal butter could possibly be good for you, and even more insane that people believe it. It feels like an over-reaction to anti-fat propaganda from the sugar lobby where we went from "Maybe eating some fat in your diet isn't a bad thing" to "YOU MUST EAT AS MUCH FAT AND OIL AS HUMANLY POSSIBLE."

keto

I think the part where the coffee is ice cold and doesn't melt butter is probably where the problems started, butter neither made it better or worse at that point

Tried this. It tasted god-awful. Personally, I swear by orange juice in my coffee.

LPT: add a lemon peel and honey to any coffee incl instant and it will taste gourmet. Add condensed milk if you're feeling fancy. This is what I do for fieldwork coffee. I learned this off a good Brazilian friend, never went back. I always do at least the peel now, it neutralises the acids.

Ah yes the keto diet.
