The invention relates to dietetic foods in the context of weight control or weight reduction, comprising at least one n3 fatty acid (omega-3) in combination with dietary fibers. Advantageously, the foods further comprise a balanced ratio of carbohydrates, protein and fat. Preferably, the inventive foods comprise a balanced ratio of fatty acids, in particular relating to the ratio n3 to n6 fatty acids (approximately 1:1 to 1:10). The inventive food combinations serve the purpose of a sufficient supply of essential fatty acids, in particular long-chain omega-3 fatty acids, in particular docosahexaenoic acid (DHA), in the context of a targeted weight reduction. The inventive food combinations are of particular advantage in the case of restricted fat supply, e.g. in the context of a reduced-fat diet with the purpose of weight reduction or weight control. In addition, the invention relates to a method for producing such dietetic foods, and also to their use.
