The news leaves me skeptical, but on the other hand after talking about the slimming power of coffee (which we have seen in reality does not exist: it speeds up the metabolism for the first time, then nothing, unless you drink liters of it) and slimming power of fats (which can increase metabolism, without exaggerating), it was a matter of time for some genius not to combine the two to obtain a kind of coffee-butter slimming drink .
In fact, adding butter to coffee instead of cream had long since become a bizarre American habit, even registered as a brand ( Bulletproof coffee ) or called butter coffee: energizing, rejuvenating, it would also help to lose weight.
According to what they say here , it is in fact possible to lose weight by mixing two cups of hot American coffee, two tablespoons of high-quality unsalted butter and two tablespoons of coconut (or palm) oil.
There is no medical evidence to confirm the slimming power of this coffee , I don’t know how else to define it. Sure, the final look may be that of motor oil, and it’s not calorie-free. In theory, it should be drunk on an empty stomach to increase metabolism and decrease hunger. In practice it seems nonsense to me.
