I don't think a low carb diet will reverse an insulin injecting patient. I was diagnosed in 2004 and had my medical withdrawn same date, haven't flow since. Been advised the CAA is more tolerant of my type of treatment - hence the question do they generally allow insulin injecting diabetics to hold a licence. Also now discovered the UK has 2 types of licence; EASA-PPL and a EASA-LAPL. Am assuming a PPL is what I would require if available, but it seems to have 2 classes of medical, class 1 and class 2. Not certain yet what I require. As an aside, the medical was withdrawn as you can pass out (have a hypo episode) if you are diabetic and have low blood glucose readings. DVLA say about 3% of diabetics have low readings, the other 97% have high readings and are not likely to pass out, me included. I have never had a hypo since diagnosis. Seems to me the CAA are on the right lines.
