Beziehung zwischen Frühstückskalorien, täglicher Energieaufnahme und Lebensmittelverzehr

Energy intake during breakfast is important for overall daily energy intake. In the present paper dietary records of 480 obese and normal weight subjects were analyzed to characterize the food items that are important for the fluctuation of breakfast and total daily energy intake. For changes of breakfast energy intake mainly food items with medium (1,512,49kcal/g) and high (2,5kcal/g) energy density were responsible. Only 10 of 32 analyzed food groups contributed significantly to the observed changes of breakfast energy intake (bread, cheese, cake, sausages, butter, marmalade, honey, eggs, yoghurt, cereals). With the exception of sausages and yoghurt the same food groups were also of relevance for changes during the whole day. When days were selected on the basis of high breakfast energy intake associated with lower intake during subsequent meals (ratio of breakfast to total energy intake) similar changes were observed for the food items at breakfast. This was the result of a significant reduction of bread, cake, cheese, sausages and carbohydrate acconpaniments during lunch. At dinner subjects consumed less bread, cake, cheese and oil. Reductions during the morning snack were due to bread and fruit. In the afternoon cake and cream, and in the evening chocolate and nuts were reduced. For dietary counseling in obesity treatment reduction of breakfast energy intake is a good option to decrease overall daily intake. There is no evidence for an automatic reduction of daily energy intake by high intakes during breakfast.
