Apart from that, the recommendation is to follow Nordic Nutrition Recommendations (NNR) for overweight people (www.slv.se), i.e. to eat much fruit, vegetables, fish, and to choose low-fat meat, and low-fat dairy products, and to avoid candy, ice cream, snacks, cakes, pastries, chocolate, potato chips, beer, soft drinks and juice. In order to match carbohydrate intake between the intervention arms, a high intake of potatoes, root vegetables, fruit and other carbohydrate-rich foods is recommended.~Guideline: 200-400 g of potatoes, 300-500 g of root crops, 400-600 g of vegetables, 200-300 g of beans, peas and corn, and 600 g of fruit and berries per day.
