But the more alcohol content it has, the more calories it has. That's the entire point of the example I made for you. The major component that gives calories is alcohol. In other words, yes there are some beverages that give more or less calories without the alcohol, the amount of pure alcohol you consume is the main source of calories - so it doesn't really matter what vessel you use for it. If you want to lose weight, you have to cut down on alcohol.
I know you don't want to. I didn't want to either. I used to be a daily drinker, and I drank heavy. However, at some point my metabolism slowed down (and I realized I wasn't accomplishing as much as I want to, but I imagine that this isn't as much of a problem for you because you are NEET [no offense meant]). As a result, I started getting a sizeable beer gut. Nowadays I've cut down to drinking once or twice a week, and I feel fine. The transition period sucked, but most days I hardly even think about drinking anymore. The sooner you cut down the better IMO.
