(HealthDay News) – In a large examination of laboratory data, fasting times were found to exhibit limited correlation with lipid levels, according to research published online Nov. 12 in the Archives of Internal Medicine.

Davinder Sidhu, MD, from the University of Calgary, and Christopher Naugler, MD, from Calgary Laboratory Services–both in Canada, examined the association between fasting times and lipid levels in a cross-sectional analysis of laboratory data from 209,180 individuals.

The researchers found that, among individuals with various fasting times, there was little difference in the mean levels of total cholesterol and high-density lipoprotein cholesterol. There was slightly greater variation of up to 10% in the mean calculated low-density lipoprotein cholesterol levels among groups of patients with different fasting intervals, and variation of up to 20% for mean triglyceride levels.

“Fasting times showed little association with lipid subclass levels in a community-based population, which suggests that fasting for routine lipid levels is largely unnecessary,” the authors write.
