Well that really doesn't make sense, since plenty of non-fat people have type 2 diabetes. That sounds like a very unscientific thing to say which strikes me as being typical of the real thoughts and feelings of many HCPs - it's all down to being fat! Of course, there's also a lot of fat people who don't get diabetes too.
Break your arm? Lose some weight! Have a cold? Lose some weight! Can't have a baby? Lose some weight! Having a nervous breakdown? Lose some weight! There, that's pretty much all the major areas covered and one, easy, dismissive answer.
Could a skinny T2 diabetic consume the 6 serves of bread/grains/legumes each day, as indicated on the eatwell thing, along with the fruit, and not see wild fluctuations in their BGLs? The advice I was given was to eat a healthy diet, and I was shown a picture of a plate which was about 1/4 bread/cereal/oats etc, and at least 2 pieces of fruit per day - and there's always a banana! That woe caused me woe. There was also a can of coke, lollies, chocolate, etc in the bottom corner under the heading "eat occasionally".
