What color is your fat?

What color is your fat?

Getting up at 4 am every day and listening to BBC World News and NPR Morning Edition can be mind broadening or maybe mind bending.

This morning there was a discussion about the color of body fat. Now having attended hundreds of autopsies I will tell you point blank that body fat is yellow. Not white. Not green. But yellow. Even the thinnest dead person has fat. Nice yellow fat. It looks just like suet that you would get from the meat cutter for your bird feeder.

This morning I found out that the bad fat in our bodies is yellow and the good fat in our bodies is brown. Yes brown. Never saw any brown fat. Apparently brown fat actually eats calories. It has something to do with producing heat. Yes calories are measured in heat production.

Anyway the study is going to be published this week in the Journal of American Medicine.

The bottom line is that if you keep your house at 60 degrees all the time your body will produce more brown fat to generate more calories or heat to offset the cold. In simple terms we are too fat because we keep our homes too warm.

There will be a test later. g
