IMHO there's no reason for a black coffee AND a Red Bull. I'd say stick with the coffee but ditch the Red Bull. Coffee does have some positive effects on metabolism due to its high antioxidant content and plant polyphenols, has some liver-supporting benefits, and aids in fat burning. For me, it also functions as an appetite suppressant. Energy drinks don't have this effect on me, which is why I prefer coffee.

But again, too much is still bad because of cortisol-raising effects as well as blunting of adrenaline-receptors (which causes some of the withdrawal symptoms).
