Am I missing something? What's with all the piss-taking?
As I said, unless I'm missing something and I'm just feeding a troll here, then well done mate, can clearly see you've lost a lot of fat around your torso. 9 months is slow not gonna lie, but you're there and that's all that counts. If you want to start leaning bulking now then go for it, if you want to get a bit leaner before you start lean bulking then do it. Entirely up to you mate. Wouldn't worry about being temporarily underweight, it won't last for too long once you build some muscle. I was underweight on the BMI scale for several years before I started lifting and I was fine, as are many people.
