Weight loss can happen to both T1s and T2s when blood glucose levels are so high that the body pulls glucose out of the bloodstream and dumps it out via the kidneys. It is dependent on having high blood glucose and insufficient insulin to lower that blood glucose.
In the past you have posted to say that you are still titrating your insulin upwards, and that at the moment your blood glucose levels are still high.
Until you get your insulin doses increased enough to control your blood glucose, then weight loss is possible (as I described above).

Please make sure that you are drinking enough, since dehydration is possible, if you are urinating enough to pee out the excess glucose.
Also, please discuss all of this with your consultant when he calls.
