Well, from what I found out, monster drinks are high in caffeine rather than glucose, so they don't give you actual energy as such, but rather a drug (caffeine) induced boost.
Proper energy sports drinks are high in calories as they do actually give you energy for exercise, which you then burn off during the exercise. They also contain water and essential minerals which you lose in your sweat.
Personally if I ever do drink sports drnks, I get the low sugar ones so I don't get the extra calories from the glucose, but I do get the minerals. I prefer to eat my calories.
I don't really know the effects of excess caffeine on weight loss. But I do know that it is generally condsidered healthy to drink less caffeine. I have cut down but I find it hard to cut it out.
ETA: I dug a little further and apparently there are ones that are higher in glucose also. I never heard of them so I don't know. Personally I'd stay away from them but it's up to you.
