Carty.
If you are trying to put weight on I am not sure that going low carb (which is in your profile) is your best way forwards....??? That may control Bg levels but you still need something filling and that will help you put on weight.
40kgs is very low....have you seen your GP and asked about something that could help you with this ? I once needed to rapidly gain weight for a job medical I was attending.......I was prescribed some sort of supplement which did the trick and helped me get my chosen career, then after eating regular meals for around three months I was then fit as a flea and fighting fit too as I also had plenty of exercise along with the food. You could possibly benefit from seeing a Dietician too, someone who can take everything into account
I have lost over 5 stone which is scattered around all over the place, you are welcome to them if you can find them........ :lol: :wink:
