Our bodies all react differently to the food that we eat, so there are different levels for all of us. The studies that are done are on a very small scale when you look at the amount of people who suffer from any type of diabetes. I got diabetes in 1979 aged 3 where you had to carb count. Then as the years have gone by new things have come on the market. When I was offered a insulin pump they said that I need to go on a 5 day carb counting course, I told them that I had been doing it for 25 years. Then they said will you go on a half day course. I went and they showed a jacket potatoe and said you will need 5 units for this, to which I replied if I done that I will hypo in less than 2 hours. In the end we went to the cafe, checked my BG ate the jacket potato and took the 5 units. Within 90 minutes I was hypoing as I said, I said everyone is a different diabetic and research is a good thing but when you get all the results, you look for the middle and that's what you go off but how many people are the average diabetic when we are told we are all different?
