Sleep routine affects your weight, diabetes and heart attack states
Finally a study shows conclusively how your daily rhythm, routine and sleep is completely tied in with your insulin activity, body weight and diabetes risk.
“Our study confirms that it is not only what you eat and how much you eat that is important for a healthy lifestyle, but when you eat is also very important”
Postdoctoral fellow Shu-qun Shi, Vanderbilt University Medical Center’s Mouse Metabolic Phenotyping Center.
The researchers have shown that disruption in the body’s circadian rhythm can lead to obesity, diabetes and heart disease.
The really interesting part is that insulin activity is controlled by the body’s circadian biological clock; when you eat - as well as what you eat - matters.
Most types of cells contain their own molecular clocks, all of which are controlled by a ‘master circadian clock’ in the suprachiasmatic nucleus in the brain.
“People have suspected that our cells’ response to insulin had a circadian cycle, but we are the first to have actually measured it. The master clock in the central nervous system drives the cycle and insulin response follows”

“That is why it is good to fast every day...not eat anything between dinner and breakfast”
