A comparison of effects of lard and hydrogenated vegetable shortening on the development of high-fat diet-induced obesity in rats

Abstract

We conclude that lard-based high-fat diets accentuate the increase in weight gain and the development of obesity and insulin resistance more than hydrogenated vegetable-shortening diets. These results further point to the importance of standardizing fatty acid composition and type of fat used in determining outcomes of consuming high-fat diets.
