Well what ever your diagnosis you are on the right track 2 stone weight loss is amazing well done ! You should be so proud !! Type 1 is based on ratios but I won't blow your mind with that ! It sounds like your having top up insulin so your pancreas is still producing insulin , this does happen with type 1 but only for a honeymoon period . Stay focused and work with your team , your attitude to your diagnosis is excellent , try to eat a varied diet and low gi food is excellent , burgen bread , brown rice , new potatoes the list is long ... All fish meat egg are carb free , but ask lots of questions from your medical team and good luck ... Sorry low gi food keeps blood levels more stable , good luck !!
