[Chances in the serum lipid values after conversion to a "reasonable" diet (author's transl)].

Six to ten days after conversion from usual alimentary habits to a so-called "reasonable" regimen, the serum concentrations of different lipid fractions were examined under standardized conditions, in a total of 325 in-patients, who had not been pre-treated, and 268 of whom showed - after diverse examinations - a hyperlipoproteinaemia; the other 57 patients had normal lipid values. This diet food is vitamin-rich, poor in calories, protein-rich with a 20 per cent to 25 per cent part of calories, poor in carbohydrates (maximum 120 g/day), and extensively renouncing monomeric and dimeric carbohydrates; furthermore, it contains a percentage of 40 to 45 calories of lipids with a standardized part of multiple-unsaturated fatty acids. During the period of observation, there was in none of the patients an alteration of the body-weight exceeding 1 kg. During the period of the regimen, the following highly significant decreases - without any medicamentous measures - were stated with regard to the serum concentrations: Total cholesterol (average) 9.9 per cent, triglycerides (average) 23.1 per cent, beta-cholesterol (average) 17.6 per cent, and phosphatides (average) 14.2 per cent - all percentages being in relation to the reference values. A hyperproteinaemia (type IIa/Fredrickson) disappeared in 14 out of 18 cases, a hyperlipoproteinaemia (type IIb) in 14 out of 44 cases, and the same happened with this disease type IV in 114 out of 206 cases. A change of type was stated 16 times.
