Direct effects of fatty meals and adiposity on oxidised low-density lipoprotein

Abstract

High-fat intake and high adiposity contribute to hyperlipaemia. In a hyperlipaemic state, lipoproteins infiltrate arterial wall where they are modified and cause an immune response characteristic of atherosclerosis. A small fraction of modified lipoproteins including oxidised low-density lipoprotein (ox-LDL) returns to circulation. The present study tracked high-fat meals during four weeks as to find effects of sustained frequency change on adiposity and ox-LDL. The findings indicated that changes in frequency of consumption of high-fat eating episodes correlated directly with changes in adiposity and ox-LDL. Hence the number of fatty meals consumed by people with overweight or obesity in few weeks could affect the atherogenic process.
