ALAYON, Alicia Norma et al. Metabolic and inflammatory postprandial effect of a highly saturated fat meal and its relationship to abdominal obesity. Biomédica [online]. 2018, vol.38, suppl.1, pp.93-100. ISSN 0120-4157.


The postprandial stage is associated with the increase of markers related to cardiovascular risk, and its intensity depends on the metabolic state.


To determine the impact of a high-fat meal intake on the metabolic and inflammatory profile, and its relationship to abdominal obesity.

Materials and methods:

This clinical trial included 42 individuals (21 with abdominal obesity). We measured glucose, insulin, lipid profile, reactive C protein, lipopolysaccharides, and interleukin 6 in fasting blood, and four hours after eating.


Besides obesity, we found insulin resistance and higher levels of fasting triacylglycerides and C-reactive protein. There were higher postprandial responses to glucose, insulin, and triacylglycerides. Interleukin 6 decreased in the non-obese group, and lipopolysaccharides increased in both groups.


A saturated high-fat food intake produced a greater impact on the glycemic variables in the group with obesity, while it affected the lipids in both groups. However, the increase of triacylglycerides was higher in the presence of a high basal concentration, and it promoted the increase of lipopolysaccharides. The basal and postprandial inflammatory state affected the group with obesity more. The postprandial moment reflected the most frequent state of the individuals on a normal day and evidenced the capacity of the metabolic response to food intake, as well as early metabolic risk states.
