Mice consuming a high fat/high cholesterol Western-type diet for 17 weeks were housed individually. Food hoppers were weighed every second day for 8 days. Mice were returned to their normal housing situations involving cohabitation with littermates for 1 month, and then the procedure for monitoring food intake was repeated. Data from 16 days of monitoring was averaged for n = 6 wild type, n = 6 PTL−/−, n = 7 CEL−/−, and n = 6 PTL−/−, CEL−/− mice and shown as the mean ± S.D. for each genotype. No statistically relevant differences in food intake between mice with various genotypes were detected.
