Effect of High Fat Diets on Energy Balance and Thermogenesis in Brown Adipose Tissue of Lean and Genetically Obese ob/ob Mice

Abstract

The effects on energy balance and brown adipose tissue thermogenesis of feeding high fat diets of differing fatty acid composition have been investigated in lean and genetically obese (ob/ob) mice. Groups of mice were fed either a low fat diet or a high fat diet based on corn oil or beef tallow for 2 wk. Energy intake and body weight gain were higher in both lean and obese animals fed the high fat diets than in respective mice fed the low fat diets. Carcass energy gain was greater for the obese than for the lean consuming each of the diets. Both lean and obese mice had a higher energy gain when fed the beef tallow diet than when fed the corn oil, despite isoenergetic intakes of the two diets. The thermogenic activity of brown adipose tissue, assessed from measurements of cytochrome oxidase activity and mitochondrial guanosine 5'-diphosphate (GDP) binding, were greater in both lean and obese mice fed the corn oil diet than in those fed the low fat diet. However, GDP binding and cytochrome oxidase activities in lean or obese mice fed the beef tallow diet were not different from those of mice of the same genotype fed the low fat diet. These results indicate that in both lean and obese (ob/ob) mice energy deposition and the stimulation of brown adipose tissue thermogenesis during the voluntary hyperphagia induced by feeding high fat diets are influenced by the fatty acid composition of the diet. A diet rich in polyunsaturated fatty acids appears to result in preferential stimulation of the thermogenic activity of brown adipose tissue, particularly in the ob/ob mouse.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
