"This article was originally published in 2004 in the Chicago Tribune. It's still knocking around on the web in various places but the original seems to have disappeared. You can't have too much of a good thing. Obviously Stephan's recent posts on lard prompted me to put this one up. The imported nutritionist doesn't seem quite as dismissive as you might expect! But notice in the last paragraph that the big bogeyman is protein overload damaging the kidneys! On 60g/d of protein??? Sobor clearly knows nothing about high fat diets, certainly not the one he is commenting so authoritatively about in this case!"

"Susceptible strains of rodents fed high-fat diets overeat, gain fat and become profoundly insulin resistant. Dr. Jianping Ye's group recently published a paper showing that the harmful metabolic effects of a high-fat diet (lard and soybean oil) on mice can be prevented, and even reversed, using a short-chain saturated fatty acid called butyric acid (hereafter, butyrate). The butyrate-fed mice remained lean and avoided metabolic problems. Butyrate increased their energy expenditure by increasing body heat production and modestly increasing physical activity. It also massively increased the function of their mitochondria, the tiny power plants of the cell."
