I was just listening to the first part of the teaching and haven't finished it yet, but you made the incorrect differentiation between Type I and Type II diabetes again Chris.
If a Type I diabetic fasts they will be able to reduce their insulin requirement while fasting because their system is not having to process food but rather they are living on the breakdown products of muscle etc, but unless they take insulin the glucose produced will never make it in to the cells that require it. A type I diabetic is on insulin for the rest of their life and will die without it.
The Type II diabetic has functioning Islet of Langerhans cells in their pancreas that are producing insulin but the insulin is not working because the person's diet and usually overeating has rendered their cells insensitive to the insulin that is present. There would be no point giving insulin to a Type II diabetic because they already have insulin present. Hence, when they start fasting and getting their diet sorted out, often their cells will regain sensitivity to insulin and they will no longer be a Type II diabetic. The reason many of the Type II diabetics managed to get by up until they were on a changed diet is because they cheated the effects of diabetes because their doctor prescribed something for them that overcame that problem of the cells not being sensitive to insulin and the glucose made its way in to the cells by changed biochemistry. Not a good doctor and not a good patient in not dealing with the cause of the problem but rather just dealing with the symptoms. I just looked it up and the chemical they prescribe usually is called Metformin. I have no idea how it works and I can't really be bothered looking either because that's pharmacy kind of stuff and I've never had an interest in that.
All that diabetic means it that a person is passing way more urine than is normal. There is a third less common type of diabetes called diabetes insipidus where the pituitary gland in the brain doesn't produce Anti-Diuretic Hormone (ADH) that has an effect on the kidneys for water reabsorption and so they also pass lots of urine and drink lots of water to compensate.
I thought I had better write this because tomorrow your mail inbox might have some angry comments from some Type I diabetics or their relatives or others about insulin and now you will be able to let them know that you made an error.
