No, just one day off at a time, then I exercise the next day again. When I worked out 6 days a week I was doing 10 hour overnight shifts four times a week. I could have spaced my workout days better, but you learn from your mistakes.
You said earlier in this thread that you don't really count calories, so how did you know that you had a fast metabolism? Were you given specialized tests by the doctor or someone in that sort of profession? Are you just going by quantity consumed visually? Teenagers usually can get away with eating more calories than an adult of the same size, obviously. One reason many fat people fail to lose weight is that they grossly underestimate the calories they consume and just think they have a slow metabolism. Most of the time, fat people actually have a higher metabolism than skinny people. Unless you really count calories, you can never be certain. I know it sounds counterintuitive when you don't have to worry about excessive weight, but it will definitely help if you learn you need to eat more.
