Almost all people have the same opinion about the causes of obesity (overweight). If not associated with excessive food intake, which must have been burning too few calories due to less activity.
Many experts now regard obesity epidemic is like a kind of lifestyle and diet is wrong. The two main causes of this was not the only one who played. An international journal of obesity has recently explained some things that can trigger the occurrence of obesity in addition to the food problem.
Slightly different from the opinion of many people and even the medical community stating that lack of sleep can lead to increased lean body, research by experts in the field of obesity to the contrary, and of course with explanations concerning the evidence could be accounted for.
From the study, found people who slept less than 7 hours a day have a risk of a BMI (Body Mass Index) greater than those who slept more hours. Initial data collected U.S. National Health and Nutrition Examination Survey was supported by the U.S. Nurses Health Study is a study of 68 thousand women aged 16 years and found that among respondents who have sleep an average of 5 hours to have more weight than the group who slept for 6 hours and lower in group 7 hours a day.
This evidence they reciprocally connected with the theory that obesity contribute impair quality of sleep in which one effect is to reduce the quality of sleep as hard to breathe or frequent waking. While the initial stage is one to explain the role of the hormone Leptin inhibits the function signal settings hungry, wake up and decreased appetite while ghrelin rose to the state instead of sleep, this has a relationship with a lack of quality sleep after excessive metabolism. Leptin levels are found decreased approximately 18% whereas ghrelin increased 28%, a result often leads to hunger.
These results supported later participated in the National Sleep Foundation survey found most of the U.S. population has decreased hours of sleep in recent years on increasing the influence of obesity cases in the country. All warm-blooded creatures including humans have a body temperature settings depending on the environment through metabolism and transpiration. This security system requires energy unless we are in thermometric zone around 27 degrees Celsius.
Temperature changes that occurred in recent decades due to various causes in the natural climate was expected to participate, which includes the use of climate regulation and cooling the engine radiator influence our weight. In the comfortable climate different for each individual energy expenditure for the settings a little more. Transpiration burning energy like a lot of hot weather in mind and a role in holding the human appetite.
