In the development of obesity are influenced by different factors than those already mentioned, genetic factors or environmental and psychological factors. It was noted that adopted children with biological parents obese tend to be overweight if their adoptive parents are not obese. However, it is unclear how genes influence obesity. Studies in mice showed that when certain genes are missing or mutated facilitated the development of obesity. However, these investigations have not had the same result in humans. On the other hand, social and family eating habits are also important and often resort to excessive intake of food in times of stress and anxiety.

Regular exercise may reduce cancer risk in women. However, these benefits could be missed if the woman is sleeping too little. Thus put forward a number of U.S. researchers recently.

The study, involving 5968 women in Maryland confirms previous findings, stating that people who perform regular physical activity face a lower risk for esophageal cancer.

But when the researchers looked at women aged 18 to 65 years of diligent exercise every week, they found that sleep seems to play an important role in cancer risk.

People who sleep less than seven hours each night to face the risk of 47 percent for esophageal cancer than those who sleep more among women who are physically active. The researchers reported that a meeting of the American Association for Cancer Research.

“We thought it was very interesting and arouse curiosity. It’s like the first time doing research. That’s not something that has been studied extensively, “said James McClain from the National Cancer Institute, part of the National Institutes of Health, the government, in an interview.

McClain, who led the study, said it was unclear how real is too little sleep may make people more susceptible to cancer. “Sleep has long been sufficiently related to health,” said McClain.

U.S. Centers for Disease Control and Prevention (CDC) called the lack of sleep as a public health problem that is not considered, and stated the Americans getting less sleep. The CDC states the percentage of adults who report sleeping six hours or less per night increased from 1985 to 2006.

Experts say lack of sleep on chronic sleep associated with obesity, diabetes, high blood pressure, stroke, heart and blood vessel disease, depression, smoking and drinking to excess.

Diabetes exacerbates

Sleep deprivation was obstructing the adrenal glands produce DHEA (dehydro-epiandrosteron), a compound that helps stimulate the sleep soundly. As a result, the body becomes more produce cortisol, a steroid trigger stress.

These conditions disrupt the body’s response to the hormone insulin, which is in charge of distribution of blood sugar throughout the body, either to be stored and reused. In the long run, the chaos of this insulin response stimulate the emergence of disturbances of type 2 diabetes symptoms are not dependent on insulin.

The low insulin response caused the decline of blood sugar (hypoglycemia), which can trigger a chain reaction. Because of the limited blood sugar levels, the brain continues to get orders for our body “stays on”. This led to a sleep disorder, which actually aggravate diabetes.

In diabetics, the sugar supply is limited due to various reasons (too late to eat, work too hard, a strict diet) can trigger hypoglycemia. If you experience hypoglycemia, patients become less sleep and interfere with healing the disease.

Monosodium glutamate is the sodium salt of glutamic acid (found in most protein foods as a protein) and obtained through a fermentation process from products such as sugar cane and some cereals.

It then passes through a refining process to obtain pure MSG. It consists of glutamate (glutamic acid), water and salt. As additive it is used as flavoring or aroma enhancer and has been using in food for half a century.

What is the other name of MSG?

Monosodium glutamate is also known as hydrolyzed protein, or yeast extract autolysates under the number E-621.Monosodium glutamate and the “Chinese restaurant syndrome”

The controversy has not ceased since 1968, Dr. Robert Ho Man Kwok, described a series of symptoms that some people presumably would feel after eating Chinese food. Some of these symptoms include: headache, asthma attacks, allergic reactions (mild to moderate), tachycardia, nausea, vomiting, tightness in the neck, face and chest and generally feeling unwell. Symptoms are usually mild and temporary. More recent studies, however, say there is no reaction and that in any case we are talking about a food allergy reaction or as may be to any other food.

Relationship between monosodium glutamate, excessive appetite and obesity

However if there is enough unanimity when we talk about its effect on appetite.
Monosodium glutamate, according to tests on animals, can produce a voracious appetite (particularly a 40% higher) and this implies that when we eat foods that contain (snacks, sausages, chips, snacks, etc..) We feel unable to stop. This may promote obesity and also talk about foods high in fat and calories.

Studies of the Complutense University of Madrid Tresguerres Jesus Fernandez, director of the Department of Physiology, Faculty of Medicine, will go on line that MSG and parties affect our brain that regulate feelings of hunger and satiety. It could also affect the production of growth hormone which is responsible for us to have more muscle, not excess fat.

People who cease to use MSG in your diet may be reduced with its voracious appetite which would make it easier to follow a diet and lose weight.

1. Hypertension
Knowledge of the relationship between obesity and high blood pressure goes back to the twenties. Since then numerous studies have confirmed this relationship so that hypertension is more than twice as common among obese than normal weight people. The central obesity or android type is more closely related to hypertension. This fully demonstrated that weight loss reduces blood pressure numbers up even normalize.

2. Venous insufficiency
Obesity, especially the type gynoid hinders the return of blood from the veins of the legs to the heart. This causes a sensation of heavy legs, but also causes dilation of veins (varicose veins), inflammation (phlebitis), itching, ulcers and even clot formation (thrombophlebitis) that can have serious consequences such as pulmonary embolism.

3. Ischemic heart disease
Obese people have higher mortality from coronary heart disease than those who remain at normal weight. In fact obesity is considered since 1998 as one of four major cardiovascular risk factors (together with hypertension, snuff and stress).

Today, this clearly demonstrated the association between obesity and heart disease like angina pectoris, heart attack and stroke. This association occurs mainly in android type obesity, which is the one with higher triglyceride levels. A decrease in weight reduces the possibility of heart disease and mortality that is associated.

4. Stroke
The American Academy of Neurology has submitted, in early May 2001, a study shows that the risk of stroke (cerebral hemorrhage both cerebral ischemia) is increased in overweight males. This risk is linear, ie, rises with increasing weight, so that each point that raises the body mass index, increased by 6% overall risk of stroke.

5. Type 2 Diabetes Mellitus
This type of diabetes occurs in adults and is associated with obesity in most cases, while 85% of type 2 diabetics are obese. It is most often associated with the android type obesity. It causes a decrease in insulin production and also to insulin resistance so that this does not serve to bring sugar into body cells.

Thus the main treatment for this disease at first is diet, trying to be balanced at the same time cause a decrease in weight, which normalizes blood sugar levels.

6. Altered blood lipids
- Increase in LDL or bad cholesterol and elevated triglycerides. The increase in blood cholesterol and triglycerides are a risk factor for diseases that affect blood vessels and heart. This occurs especially in android type obesity. Weight reduction improves the levels of these lipids with the consequent reduction in cardiovascular risk associated with it.

- Decreased HDL or good cholesterol it decreases the cholesterol deposits on the wall of the arteries by preventing these from being blocked with protecting myocardial infarction and stroke.

7. Increased blood uric acid
Increased uric acid, with the consequent possibility that this precipitate in the joints (mainly the toes) and rise to what we know as gout. This disease is associated historically with obesity – who does not remember the king’s image with fat foot raised by the attack of gout? -.

8. Arteriosclerosis
It is favored by a deposition of fat in the inner lining of the arteries which reduces its internal diameter with a consequent decrease in blood passing through them and therefore with a lower blood supply to irrigated areas. As a result can lead to heart attack, thrombosis or circulation problems in legs. This is a slow and silent face not giving up after many years of starting.

The factors causing this disease in addition to increased blood cholesterol, smoking and hypertension and to a lesser extent increased blood triglycerides, diabetes mellitus and physical inactivity. The more factors are given in the same person, the more likely you are to suffer arteriosclerosis.

9. Osteoarthritis
Excess weight causes extra wear on the joints of the body that are subjected to a greater than normal effort. Then comes pain and difficulty in movement, especially in joints that are called the load of the spine, hip, knees and ankles.
Besides excess fat in the joints alters the correct functioning.

10. Respiratory
The accumulation of fat in the chest makes breathing movements of the lung, altering respiratory function. These alterations are greater during sleep causing the so-called sleep apnea. This condition is a temporary interruption of breathing that is recovered with a big snore. At this time lack of oxygen supply to the brain, which can provocaralteraciones heart rate, hypertension crisis or strokes.

Besides the quality of sleep is poor and the affected fall asleep at any time during the day, which poses a risk of accident if you are doing any activity that requires full attention as driving or operating machinery.

11. Digestive disorders
Excess fat in the abdomen increases the pressure at this level. On the one hand, this favors the herniation of the stomach through the diaphragm so that goes to the chest causing what is known as a hiatal hernia.

On the other hand hinders the proper functioning of the so-called cardiac valve located between the esophagus and stomach, preventing the passage of stomach contents into the esophagus. Thus the gastric juice is very acid irritating the esophagus passes the walls and causing esophagitis manifesting as burning sensation and causes injuries to the esophageal mucosa. Besides obesity, especially type gynoid, predisposing to stones in the gallbladder and liver degeneration.

12. Neoplastic diseases
Obesity is a risk factor for various cancers. In humans increases the likelihood of colon cancer, rectal and prostate cancers in women and promotes the growth of ovarian cancer, uterine (endometrial and cervical), breast and gallbladder.

13. Risk in the operating room
The excess fat hinders the realization of any surgery for several reasons. On one hand it is a physical obstruction to access to the areas involved. On the other hand changes, as we have seen, occur in respiratory function, increases the risk of complications. Also in abdominal surgery excess fat delays healing and promotes infection.

14. Mortality
Being overweight increases mortality in the population that suffers. A Body Mass Index (BMI) greater than 29kg/m2 mainly produces higher mortality from cardiovascular disease, stroke, type 2 diabetes mellitus and some cancers.

The risk of heart attack and strokes increases especially in cases of android type obesity that is where the excess fat is distributed around the abdomen. This demonstrated that weight loss and normalization of BMI decreases the risk of mortality from diseases associated with obesity.

“Most fast food hear that promotes excessive food consumption and obesity, and some studies supported this idea,” said Dr. Alexander Kokkinos, lead author of the study.

But what was unknown was the biological evidence that a quiet meal is better for appetite control, said team Kokkinos, School of Medicine, University of Athens, Greece, and Imperial College London, in the United Kingdom.

To study the authors reported them to 17 healthy men eating a generous portion of ice cream in two different situations: in one, in two portions over 5 minutes in the other, in small portions over 30 minutes.

Although the feeling of satiety and hunger in both groups did not differ, the researchers found that men who ate slowly, suffered an increase in the blood of two hormones, peptide YY (PYY) and Glucagon-like peptide 1 (GLP-1) – for three hours after eating ice cream.

The PYY and GLP-1 is released into the digestive tract as a sign of “fullness” to the brain, reducing appetite and calorie intake.

The results, approved for publication in the Journal of Clinical Endocrinology & Metabolism, support the popular wisdom that you have to taste the food.

Some previous studies have shown that when people take the time to chew food and enjoy it, they tend to eat fewer calories when they eat the same food at full speed.

But is not known why this difference.

“Our study offers a potential explanation of the relationship between eating quickly and overdoing it by showing that the rate at which a person eats alter the release of gut hormones, which tell the brain to stop eating there,” said Kokkinos.

The results are particularly relevant when many people choose fast food and eat in a hurry, he adds. The study suggests that reducing the speed at lunchtime favor appetite control, and finally weight.

This is a possible explanation for “the warning they gave us children that ‘devour food fattens you,’” Kokkinos ended.
