Study: 15 % of Finnish adult population follows low-carbohydrate diet
According to annual Finnish health survey called "Health Behaviour and Health among the Finnish Adult Population", 13,4 % of all adult males and 16,4 % of all adult women followed low-carbohydrate diet in 2011. This was the third most popular choice of the studied diets after low-fat diet and lactose-free diet. However at the same time 60 % of the adult male and 44 % adult women population were overweighted (BMI >25 kg/mē). This is the first time the study included diet preferences.
You can see the distribution of diets on Table 123a on page 160 of the study.
