It's dangerous if you read "fasting can cure your diabetes", when the article is about mice.
For the record, I have friends that are fasting, and family members with diabetes.
If you have diabetes you can't fast without correcting the dosage of insulin that you're taking. If, for example, you take a normal dosage of insulin, but fail to consume the corresponding amount of sugars, your blood glucose level will start decreasing. Soon you will faint, and your level will still go down. Next step is coma, and finally death. So yes, I consider this dangerous.
The article also says "People are advised not to try this without medical advice.", to reiterate that it is dangerous.
