Obesity has been the recent popular "epidemic" to cause havoc among the people in recent years, with the zero figure becoming the new In-Thing. The duality of this issue is that on the one hand, the world is getting fatter and fatter with the growing popularity of junk food in the market, and on the other hand fitness standards that are acceptable have grown increasingly rigid in order to sustain the increasingly vulnerable human body. With a lot of research and analysis being put in to understand and counter obesity, many contributing factors have been found:
- less physical activity
- high caloric intake
- genetic interaction with environment
- cultural influences
- sleep deprivation
Recent research conducted by various scientific groups, in order to fight obesity has shown that sleep deprivation, to a certain extent, does affect our weight. To understand this, we must look at our history. With electricity and other technology allowing us to expand our day, we sleep almost 27% less daily as our ancestors. This has also been factored with the rise in obesity over the last century, and the resulting prognosis is as follows: Getting less than 6 hours of sleep in a day can increase the likelihood of obesity.

Studies supporting this statement have demonstrated that 1.1 million people worldwide have recorded an increase in their Body-Mass Index (BMI) when their sleep cycles fell to below 7 hours daily over a period of time. For those who aim to lose weight, this is definitely something to keep in mind.
Studies have shown all kinds of trends, such as when a person's sleep pattern falls below 8 hours, the increase in that person's BMI would be directly proportional to the decrease in the sleep. A test done on 45000 children showed that the lesser the child sleeps, the more he or she is at risk of becoming obese. The explanation has been found in that lack of sleep leads to impaired glucose tolerance, which is a marker of the following:
- Diabetes and insulin resistance
- Reduced Leptin - a hormone that usually suppresses appetite
- Increased Ghrelin - a hormone that increases a person's appetite
Knowing that a good night's sleep is the easiest way to stop gaining weight is a stride forward at shedding it. It proves that simply making lifestyle changes such as a longer sleeping schedule can lead to a better metabolic health free of the risk of obesity.
