My Body Clock

Ok.. I'm sleeping way too late now, I sleep around 3:00 A.M. or 4:30 A.M. sometimes around 7:00 AM in the morning since last 3 years ago or more. The problem is.. if I sleep too early like 9:00 P.M. I usually ended waking up too early and I can't easily go back to sleep. And maybe because of my high-fat diet.. i'm eating to much and getting fattier every second. That's really horrible.. me? FAT?!

I guess it's time to realize that Iim cutting my lifespan short. NO!!!!!

Somebody HELP ME!!

High-fat diet can alter body clock -- study

CHICAGO -- A high-fat diet is not just bad for your heart, it can also throw off your body clock, setting off a chain reaction that interferes with many metabolic functions, a study released Tuesday said.

The study in mice suggests that the functioning of the body's internal 24-hour clock, which regulates our sleep/wake cycle and the timing of hunger pangs, is closely tied to the rhythms of certain metabolic processes.

A Western-style diet with a lot of calories from saturated fat can disrupt the body's clock or circadian rhythms, setting up a vicious circle which throws off the timing of certain metabolic processes, potentially increasing the risk for obesity and diabetes.

"Timing and metabolism evolved together and are almost a conjoined system," said Joe Bass, lead author on the paper and an endocrinologist at Northwestern University in Chicago.

"If we perturb the delicate balance between the two, we see deleterious effects," he said in the study published in the journal Cell Metabolism.

He took two groups of mice and put one on a regular diet and the other on a high-fat, high-calorie diet for six weeks.

After two weeks, the mice on a Western-style diet with 45 percent of their calories in the form of fat, showed a spontaneous shift in their normal pattern of activity-eating and rest-sleep rhythms.

They began to eat during their typical rest or sleep period. The mice on regular diet did not show this behavior.

"It's not just that the animals are eating more at regular meals," said Bass. "What's happened is that they actually shift their eating habits so that all excess food intake occurs during their normal rest period."

In addition to the behavioral changes, lab tests showed that levels of certain messenger molecules produced by genes that regulate circadian rhythms were depressed in the brain, liver and fat tissues of the mice on the Western-style diet.

"One of the damaging effects of excess calories is to perturb this very delicate and important timing mechanism that is present in all of us," said Bass, noting that the internal 24-hour clock is a feature common to plants, animals and humans.

"In so doing, it may exacerbate the process that connects diet to diabetes and obesity."
