Your ability to lose weight or put on muscle are going to be constrained by a wide variety of factors including what nutrition you're getting, how much water, how much sleep, what intensity of exercise at what heart rate... even frequency of meals. Hell, you might even be eating too little food, or the wrong food for your metabolism or pH. I've had to tweak ALL of these things in order to lose weight. How many have you tried tweaking? There are tons of variables that could act as constraints on your ability to lose weight, and until you make sure they're all simultaneously satisfied, you're not going to get a result.

I don't know you, but I'd guess that you're deluded about how much productive tweaking you've done. People are useless at figuring out what causes what when there's a large time-lag between cause and observed effect, especially when there's lots of noise too.
