Ahk, I will defiantly increase my calories from what everyone is saying here. I am at home now, so I do have a little more freedom, but I'm not entirely sure what the best/safest things to do other than small weights would be to work out?  You seem to know a lot more about this than I do, is there any specific types of food I should be eating more/less of? At the moment I'm eating a very high fibre, low carb diet, as the painkillers unfortunately mess up my bowels pretty bad... And any other exercise you could recommend?
