[Carbohydrate-reduced diet and metabolism: about the influence of a 4-weeks isocaloric fat-rich, carbohydrate-reduced diet on body weight and metabolism (author's transl)].
The influence of a 4-weeks carbohydrate-reduced, fat-rich diet on 9 slightly overweighted men was investigated. Caloric and protein intake remained unchanged. 70% were fat, 20% carbohydrates. Glucose, cholesterol, triglycerids, serumproteins, urea, uric acid, sodium and potassium were measured in rest. At a 60 minutes bicycle ergometer test glucose, triglycerids, free fatty acids and glycerol were registrated before and after 20 and 60 minutes work. The intensity was 70% of the maximal oxygen uptake. These were the most important results: (1) Body weight decreased continuously. One of the causes is an elevated heat production. (2) Serum-protein and -glucose remained unchanged. Cholesterol and triglycerides were reduced. Serum-urea, -sodium and -potassium diminished continually. On the contrary, uric acid raised over the normal range. (3) Work performance was reduced for 20%. (4) Hypoglycemic values did not appear. The oxidation of fat by the working muscles, and fat mobilisation increased by a fat-rich diet.
