En överätning innebär alltid en vikt- och fettökning, men det spelar ingen roll om det är överätning av fett eller kolhydrat; påverkan på kroppssammansättningen är densamma.
Citat:
Energy cannot get lost; energy that is not expended will be stored. As the digestibility of foods is not affected by intake level or subject, energy storage during overfeeding can be calculated as the difference between energy intake and energy expenditure.
With carbohydrate overfeeding 75 to 85% of the excess energy was stored and the remaining expended, while with fat overfeeding 90 to 95% of the excess energy was stored, but there was no difference in fat storage after 14 d between the two diets fed isoenergetically to the same subjects.
