5:2 and Diabetes - Can they mix?

[terminalerror]

Hi everyone, new here so sorry if this is well-covered ground.

I am fairly new to this 5:2 concept and with all of the incredible information I've found here, I'm really excited about this journey! I'm also seeing a lot of potential health benefits, but there's one gap I have concerns about. I'm hoping to mine some of the experience here to get some insight.

I would be interested in introducing this diet to my middle-aged parents (50). I have seen some notes about how this diet may not be ideal for people with diabetes. This is because of the risk of becoming hypoglycemic on fasting days, ie blood sugar levels dropping to potentially dangerous levels.

I'm looking to understand:

• the exact risks associated with this diet for people with Type 1 Diabetes.
• will the body respond differently to this diet than someone who is not diabetic?
• are there ways you can increase your sugar levels while still maintaining the 500/600 calorie limit? ie including a glass of juice, taking sugar pills, etc?

Is there anyone here who is diabetic/medically inclined and can provide advice on this?

Note: of course we will consult a specialist before taking any risks. :)

Yes, medical advice is essential for Type 1 or 2 diabetics considering ANY type of IF (Intermittent Fasting)

Your doctor might want to monitor / change any medications, even if they agree to your doing IF.
Or they might say IF is too dangerous in your particular case.

Intermittent fasting has quite different effects on those with Type 1 to those with Type 2 diabetes, but "safety first" applies to both.

There are no studies yet wrt diabetics on 5:2 or ADF, but Mosely advises against 5:2 for Type 1
There have been studies on Ramadan, involving daily fasting with a short eating window:
For Type 1 diabetics, doctors warn of risks of sever complications: BMJ , DiabeticsJournal

Some folk with Type 1 diabetics have posted success online - e.g. FastDietForum , ManageDiabetes - but they don't mention any medical supervision or advice, which I found concerning.

Ask your doctor about 5:2 with 1000-cal FDs
We advise any BFers to do these higher cal FDs. They lose weight more slowly than classic 5:2, but it is lower stress and much safer.
For Type 1 diabetics, I think meals should be spread out more over the day, instead of in the reduced eating window we recommend for non-diabetics.

For anyone wondering about IF on Type 2 diabetes, risks seem low both for Ramadan fasting and daily 16:8 for weight loss, e.g.
A study on people with Type 2 diabetes in DiabetesJournal found that eating only breakfast and lunch (which is just 16:8) was better than 6 small meals (with same total calories) for reducing weight and fasting glucose.

Varady and others have shown ADF can help avoid Type 2 diabetes in those at high risk. So, 5:2 is probably also helpful.
Again, if you actually have Type 2 dianetes, consult your doctor before daily IF or 5:2 / ADF.

Thanks so much for all the information. I'll use this as a starter to discuss with a specialist.

Appreciate your time!
