Also, don't get too hung up with the scales. You say 145# and 15% fat. When someone mentioned 10%, you said you'd be too scrawny. Well, that's only one way to get to 10% bodyfat. The other way is to add muscle. If you would be happy at 145#/15%, then would you be disappointed if you were 150#/10%? My guess is that you would be happier with the latter. The scales can often cause unnecessary and unproductive stress.
