A study that was published by the University of Leeds for the PLOS journal found that a lack of sleep in one’s life could end up causing serious weight gain problems.It may particularly cause a person to develop obesity.

The new study reviewed 1,600 adults in terms of their sleeping and eating habits.It included regular measurements of each person’s weight, waist size, and blood pressure.

The analysis found that those who do not get a regular amount of sleep each night will be more likely to become overweight and struggle with obesity.

The 1,600 people who were reviewed were from a diverse grouping of people although a little more than half of them were women.Also, the people were from 19 to 65 years of age and were analyzed over the course of a few days with their dietary habits analyzed in appropriate journals.

Specific Totals

There were several specifics found within the study.First, the body’s weight was linked to sleep in that a person who sleeps less will be more likely to gain weight.It is estimated that a typical person gained about 0.46 kilogram per square meter of body mass for every fewer hour of sleep.

Meanwhile, a typical person will gain 0.9 cm of waist size for every hour of sleep that is lost.This means that a person could potentially gain an added inch of waist size if one is getting a significantly short amount of sleep.

The BMI, or Body Mass Index, was particularly noticeable in the study.A person who gets eight hours of sleep will have one lower point on one’s BMI than someone who gets only six hours of sleep.That number increases to around two when four hours of sleep are considered.

Also, the total HDL cholesterol amounts in those who get enough sleep were analyzed.These totals were found to be strong as there were minor increases in HDL cholesterol totals among those who get more sleep in a typical evening.HDL cholesterol has been noted for being the “good” form of cholesterol which assists in improving how vessel walls are formed, thus regulating a healthy blood pressure level.

No Dietary Influences

The study did not find any significant changes in the results based on the overall dietary habits of people.This comes amid the common belief that a lack of sleep often causes people to overeat.

An analysis of food found that there had been very few changes between each person in the study in terms of one’s dietary habits.There was very little deviation in the diets of those who do get enough sleep and those who do get it.

The body’s fasting glucose or blood sugar rate did not appear to have any changes as a result of the total amount of sleep one gets.The total amount of LDL cholesterol, a harmful form that restricts blood flow, did not appear to be impacted by the amount of sleep one gets.

The General Cause

There is also the concern that the body’s metabolic rate will suffer when one is not getting enough sleep.As the body gets into the deeper stages of sleep, its metabolic rate has been measured as improving.It can move back to the body’s natural rate when it is fully restored.

This could especially be linked to the production of critical neurotransmitters in the brain.When the body does not get enough sleep, the brain produces less leptin, a hormone that tells the body to stop eating.This in turn reduces the ability of the body to keep from consuming foods.

The study still revealed that there was not much of a dietary change among those who slept less.Even with this in mind, further reviewed may be required to understand how such changes might work.

How Much is Needed?

The University of Leeds study found that there is no definite answer as to how much sleep people need in order to lose weight.It was estimated that around seven to nine hours of sleep a night are recommended.

The results of the study suggest that there is not too much of a deviance between the seven to nine hour marks.However, those who sleep for more than nine hours are not going to get much of a benefit off of that extra sleep.This comes as the decline in one’s typical waist size and BMI starts to taper off at the nine-hour rate, thus making it so a significantly larger amount of sleep is not going to do much for a typical person.

The general results confirm that getting enough sleep is critical to having a healthier life.This includes ensuring that one is able to keep from gaining more weight.
