We carried out the analysis of the changes in the spectrum of neutral lipoids and phospholipoids in blood serum as a response to meals in girls of different somatotypes. We revealed statistically true lowering of lipid acids content in representatives of all examined somatotypes after meals. Statistically true increase of simply oxidized fractions of phospholipoids in girls of sub-athletic and athletic somatotypes testifies on the change in the ratio of dynamics components of lipoid spectrum of lipoproteids. Balanced fractions of phospholipoids as well as free cholesterol are the main structural components in lipoproteid membranes and they didn't change in any of the studied somatotypes as a response to meals. This proves the stability of membrane structure of lipoproteid complexes as a response to the given physiological stimulus.
