I have type 1 diabetes, so my pancreas can’t deliver insulin. Now when I fast, my blood sugar rises. Be it through strenuous exercise or simply by natural means after getting up in the morning. In healthy people, the body automatically releases a little bit of insulin to control blood sugar. If I now have to inject insulin, for example because my blood sugar has risen during the night, does it break my fast because it is a large amount of insulin at once and not continuously and small as in healthy people? In my opinion, it would have to break the fast, because sugar goes from the blood into the cells. On the other hand, this also happens in healthy people, only more continuously. I’m really only talking about increased blood sugar by natural means. Not if, for example, I have injected too little insulin in the evening and have to correct it in the morning.
I have long searched the Internet and could not find anything. I look forward to any answer even if it is only guesses! Thank you!

No, it is not going to break a fast. You’re moving extra glucose from your blood into cells, but it’s not coming from food you’re currently digesting.
All of us have extra glucose reserves stored in our liver. And when we’re (us non-diabetics) are fasting we are either using glucose from our liver, or our bodies are breaking down fat cells to get extra glucose stored there.
You break a fast when you eat something and you’re body starts getting glucose from food you’re digesting.
It definitely doesn’t break a fast.
Good question. Obviously only correct with the rapid acting insulin you need as you have to eat fast acting carbs if you go hypo.
Fasting with Type 1 is a balance. You want to cut your basal insulin enough to get into ketosis but you don’t want high blood sugars.
Always correct significant hyperglycaemia with insulin.
Always break a fast if you don’t feel well.
You really need to test blood ketones. Get a ketomojo. You really need your fluid and electrolytes on point. You may need a lot more sodium than most people. Magnesium levels are often low to start a fast as hyperglycaemia is a magnesium wasting state.
Drastic weight loss could be dangerous dehydration.
It might be more productive to talk to the endocrinologist about low calorie dieting than to talk about fasting. Fasting can be done safely with Type 1 but you can’t expect endocrinologists to condone fasting. It’s not in their scope of practice.
You need to talk to your doctor. You should not be non-compliant with your insulin. Sugar entering your cells does not break a fast, on a cellular level of your cells are not intaking sugar you’re dead. By fasting and not taking your insulin as a type 1 diabetic you’re just pushing yourself toward Diabetic Ketoacidosis much quicker than normal. Please talk to your doctor and use your sliding scale as prescribed
The answer to your question does not matter because you absolutely still need to take your insulin as recommended so you don’t damage your body with hyperglycemia or god forbid go into diabetic ketoacidosis.
Have you read the obesity code? Fung discusses Type 1Diabetes in a few places. The primary reason for Fasting is to lower insulin so that the body can access fat stores for energy production. It seems the answer to your question has more to do with the total level of insulin in your body and the ability to burn fat in a calorie deficit.
Experimenting with a continuous glucose monitor could be helpful.
i would say no, you and your body are doing the best you can to manage you blood sugar levels. the fact that you are doing it manually makes no difference as far as im concerned. plus i agree with everyone else, go talk to a doctor and find out if its a healthy thing to be doing, and how best to keep your insulin in line with what it should be. going to guess what it should be will have little resemblance to normal eating insulin levels
You definitely shouldn’t fast if you have diabetes, more so if you haven’t consulted with a doctor. So only start fasting after and if your doctor says it’s okay.
Nothing is more important than your health so take care of your body and know your limits.
