The Body Clock vs. Body Fat


The Body Clock vs. Body Fat

According to a recent research by scientists at The University of Manchester, the body clock plays an important role in body fat. In the words of Professor Ray " Essentially we discovered that the circadian clock, protein REVERB plays an important role in the safe accumulation of body fat. Usually as fat accumulates there is inflammation in the body which leads to diabetes and heart disease. Our research shows that this process is linked to the body clock."
 

The idea of a biological clock may sound like a quaint metaphor, but there is actually a very distinct brain region that is charged with keeping time: It is an area called the suprachiasmatic nucleus (or SCN), situated right above the point in the brain where the optic nerve fibers cross. This location enables the SCN to receive the cues it needs from light in the environment to help it keep time.
 

The team found that REVERB affects obesity-related inflammation by regulating both,

  • a hormone that comes from fat, adiponectin, and

  • a master regulator of inflammation A20

It is known that the body's clock is responsible for more than just sleep and wakefulness. Other systems, like hunger, mental alertness, and mood, stress, heart function, andimmunity also operate on a daily rhythm. It was further observed that patients who undergo weight loss surgery had both an increase in the hormone adiponectin in the circulation, but also the inflammation regulator A20 in fat itself.
 

Previous studies have also shown an association between the dys-regulation of circadian or body clock rhythms and some metabolic disorders. Disruption of circadian clock regulation plays a key role in the development of metabolic diseases, including obesity and diabetes. Eating unhealthy foods causes health problems and that it's much worse to eat unhealthy foods at the wrong time.

Healthy clockwork = healthy body and mind

The Body Clock vs. Body FatThe human body is a cyclical machine, and circadian variation in physical and cognitive performance is readily observable at both the individual and population levels. These behavioural outputs stem from circadian regulation of neuronal, physiological and endocrine function; examples include rhythms in core body temperature, heart rate, and in cortisol and melatonin secretion . Indeed, the majority of body and cell functions, appear to have some circadian component. For example, elements of both the adaptive and innate immune system are subject to circadian regulation , as is the severity of many disease states including myocardial infarction and depression. More than 20% of gene expression in a given tissue has been estimated to be under circadian regulation at either the transcriptional or protein level, with further circadian regulation being evident through post-translational protein modification.
 

There is no doubt, that our bodies are temporally orchestrated by the clockwork. Whether it is the regulation of daily cell metabolism, the cell division cycle or the modulation of mood and neurological function, the circadian clockwork is hard-wired into all body processes.
