I was diagnosed as type 1 and told I had to start insulin straight away, but managed to stay off insulin for the first two years with exercise and intermittent fasting, eating low carb and only one meal a day. I had to monitor my ketones and got a c-peptide every 3 months to check for deterioration Eventually, my blood sugars were above 13 mmol/l and nothing would bring them down, so I accepted I needed insulin. If I started using low doses of insulin, I may have been able to extend my honeymoon period by preserving beta cell function, so I'm not convinced I did the right thing. I was scared of insulin, the hypos, the variability, I guess. On reflection, once you have to start taking insulin, it's not the end of the world.
