BMJ readers

Thanks Nina for this insightful and evidence based piece .

I am a Family Physician in the number 2 obese state in the USA - West Virginia and yes you can reverse T2DM and prevent it with low carb healthy eating.

If you look at the rise in obesity and the implementation of the 1979 US dietary guidelines there is no doubt a direct correlation if you overlay the maps. Based on this we need to reframe our assumption and maybe take the null hypothesis to be that we would have a healthier nation if the government (or their agencies) did not tell us how to eat. Given this past history of a failed experiment we need to be really careful that all the evidence and options are explored and studied before discarding Jennifer Elliott.

There is undeniable basic science that healthy essential fats are needed for a healthy body and just by the fact that the food category of fats does not appear on the "my plate" (USA) is concern in itself that may be our governments needs to relook at what they are promoting. If a citizen with no nutritional background were to look at a plate the government is promoting and it does not even include fats he/she would take the assumption that fats are inherently bad and should be avoided at all costs. This is what many in our country do and their health suffers the consequences. We also as a profession do not understand the breadth of insulin resistance and a Blue Zone style diet might not be optimal for them, even if optimal for one who is not insulin resistant.
