We see all kinds of routines for dealing with diabetes.Since diabetes is a very vague term, It is common to see a wide range of answers.
The good thing is that we are active in the pursuit of control methods The bad thing that some seem to think that their solution is for everyone. I prefer to keep an open mind and look at all approaches. Most studies and books are well written and very plausible. They spend a lot in editing and refining the books. It is usually a narrow and plausible presentation. Not suitable for real world diabetic care.
