“Roll the clock forward, and here we are in 2016 with whole countries refuting the fat is bad, sugar is good mentality. Sweden has adopted a low-carbohydrate approach to public health messaging, lifestyle choice, and health interventions. The switch in dietary advice followed the publication of a two-year study by the independent Swedish Council on Health Technology Assessment. The committee reviewed 16,000 studies published up until 31 May 2013 and upended existing advice in favour of a low-carbohydrate model. Here in the UK we see, almost weekly, documentaries and publications advocating that we reduce our carbohydrate intake, especially for the treatment of obesity and diabetes, and yet the accepted advice is still low fat.”
