"Mice fed a high-fat diet experienced a sudden disturbance in their
circadian clocks, which caused them to overeat when they should have been
resting or asleep."
According to a more detailed article, the mice were fed a diet containing 45% fat for two weeks to create the disturbance of the body clock. There was no mention as to how they controlled for other nutrients (if half the calories are coming from fat, how nutrient-dense are the rest of them? Are the control mice getting more vitamins and minerals, and that's having an effect on the circadian?)
"The eating behavior of mice in the study mimicked that of people who experience munchies non-stop and then, after snacking all day, launch midnight raids on their refrigerators, Bass said."
Oh, right. I forgot. Fat people are fat because they eat ALL THE TIME, day and night, never pausing in the quest to stuff their face with baby flavored donuts and milkshakes made from kittens. How silly of me.
I really need to get a subscription to access studies beyond the abstract. I'd really, really like to know details that get handily left out by the media. What was the activity level of the mice? What were the total calories consumed by each group? Did they try a group of naturally fat mice as a control, or just overfeed a bunch of thin mice to make them temporarily fat (which would indeed mess seriously with their biological functions)? Did the researcher find out if the circadian is altered in mice that were born fat?
More importantly, why didn't I know that all fat people sleep badly? Gosh and Geburah, this could explain everything! Sleeping pills for everyone, lets cure this pesky epidemic.
