The cost of low carb is to some extent the elephant in the room as far as controlling type 2 is concerned. Even in the relatively wealthy UK some people are already buying the cheapest cuts of meat, bulk buying when there are offers, shopping at Aldi or Lidl just to feed themselves, never mind buying more expensive stuff because they can't eat the cheaper carbs. If there was widespread adoption of a low carb diet then the cost of meat, fish, vegetables, salad etc. would increase in price due to demand and put them out of reach of many more people. I am sure that it must be impractical for doctors to suggest to their poorer patients or those with an ethnic high carb diet that they should cut out the carbs and are suggesting higher GI versions as a lower cost but less effective compromise. Those of us who can afford a LCHF diet should realise that we are fortunate that we are able to control our BG with a method not easily available to everyone.
