Hi, although I am not yet confirmed as being diabetic I have been reading about a complication that diabetics can get called ketosis which I think is something to do with burning fat which is the point of dieting? The pharmaceutical companies say that it is serious but can only come about from eating the wrong things. They say there is a simple urine test that can be done but I don't want to spend money unnecessarily and that may be just what they want me to do. Does it only occur with people who are overweight, or is it something that I should be asking my GP to check? As I am not carrying excess fat (I don't think!) maybe I am immune to this?
