Serious question: how does a ketogenic diet work for people with type 1 diabetes?
Can you achieve stable blood sugar levels?
Does it mean lower insulin doses and less blood glucose testing?
Does it make you more vulnerable to hypos?
Is it too easy to slip from ketosis to ketoacidosis?
Can it be done safely?
Low carb or keto is helpful for type 1 (or any of the low/no insulin production types.)
Low carb means the range of readings the patient has to control is generally narrower. Lows are the result of too much insulin. Trying to get to 100 from 300 without going below 70 is riskier than from 150. Low carb/low insulin intake makes exercise safer.
Operating in a narrower potential range of readings means less development of insulin resistance and easier exercising safely.
It's challenging to start a low carb diet while taking insulin, so please be careful and talk to your doctor. For me, reducing my insulin "too much" while starting the diet made the transition nearly free of lows at the acceptable expense of fasting too high for a few days until the new situation became stable, but I realize not everyone can do that.
