Timing our meals can fend off diseases caused by bad genes or bad diet. Everything in our body is programmed to run on a 24-hour or circadian timetable that repeats every day. Nearly a dozen different genes work together to produce this 24-hour circadian cycle.

These clocks are present in all of our organs, tissues and even in every cell. These internal clocks tell us when to sleep, eat, be physically active and fight diseases. As long as this internal timing system work well and we obey them, we stay healthy.

Mice that lack critical clock genes are clueless about when to do their daily tasks; They eat randomly during day and night and succumb to obesity, metabolic disease, chronic inflammation, and many more diseases.

Circadian Clocks

Even in humans, genetic studies point to several gene mutations that compromise our circadian clocks and make us prone to an array of diseases from obesity to cancer. When these faulty clock genes are combined with an unhealthy diet, the risks and severity of these diseases skyrocket.

Time-restricted eating

The benefit surpasses any modern medicine. Such an eating pattern popularly called time-restricted helps overweight, and obese humans reduce body weight and lower their risk for many chronic diseases. 

Decades of research had taught us what and how much we eat matters. But the timing of eating is like an external time cue that signals the internal circadian clock to keep a balance between nourishment and repair.

Eating And Fasting

They thought that the timing of eating and fasting was giving cues to the internal clock timing cues to the internal clock and the clock was flipping the switch between nourishment and rejuvenation every day.

Broken Internal Clock

In a new study,  they took genetically engineered animals that lacked a functioning circadian clock either in the liver or every cell of the body To test if time-restricted eating works with dysfunctional clock, we simply divided these mutants into two different groups one group got to eat whenever they wanted, and the other group was only given access to food during restricted times.

Restricted Eating Times

But to our utter surprise, the restricted eating times trumped the surprise the restricted eating times trumped the bad effects of faulty clock genes.
