IWTL how to get into shape for the first time in my life.

I subcribed to /r/fitness and started reading the FAQ and it just seems so intimidating. As an obese person I feel like I'm almost looking at rocket science about counting carbs and etc. I just want to build some muscle but not to the point where I look like I'm a meat head and lose some pounds. I want to look fit.

I'm only 5'6 and weigh 161 pounds. I have a big gut and abnormally large moobs. I'm willing to take pics if anyone really wants me to.
