Central obesity, diet and metabolic syndrome

Although there were a few recent reports that fat distribution does not poses a health risk but total fat greater percentage, there were still many investigations on the impact of Central obesity on health, suggesting that visceral fat (internal) is a major health risk than subcutaneous fat (under the skin).

Metabolic syndrome is a condition that really describes the set of conditions that together much increases the risk of developing heart disease and type 2 diabetes. A recent book, published in February 2011, looked at central obesity and the metabolic syndrome and has determined that, after a Mediterranean diet it may help reduce the symptoms of the metabolic syndrome.

Conditions of the metabolic syndrome
"Disturbances" that lead to an increase in the risk of diseases of the heart and diabetes are:

CSC: excessive fat in the blood

Hypertension: hypertension blood pressure

Hyperglycemia - high sugar in the blood (glycemia) in obesity blood

Central - aka adiposity

Insulin of fat / Central resistance, also known as the visceral belly - fat when the body no longer meets the insulin and cannot reduce inflammation of the level of blood sugar levels

Low - when internal organs suffer inflammation in response to immunological problems.


It is estimated that the metabolic syndrome affects 34% of the population of the United States. OHS to increase the chances of developing diseases of the heart by 2 and the risk of developing type 2 by 5. Up to 34% of Americans now are 5 times more likely to develop type 2 are only those in good health.

Causes of metabolic syndrome

The main causes for the development of the metabolic syndrome are:

The socio-economic situation of the diet of habits

Low of exercise

Poor

Smoking

Lack

However, there is some evidence that a healthy diet can actually reverse the condition, or at least minimize the risk of development. And it is almost not lose weight, while central obesity is without doubt a problem yet. The answer seems to be the Mediterranean diet.

The Mediterranean diet and metabolic syndrome

Already, there was some research to suggest that obesity alone is not the cause of Metabolic syndrome. It seems that this happens that generally those who follow a diet that leads to insufficient Metabolic syndrome are also more likely to Central obesity.

The real issue is specifically the diet and not the level of deposits of fat in the body. The latest research examined the role of the Mediterranean diet and levels of metabolic syndrome and found;

"Accession to the Mediterranean diet (high consumption of whole grains, fruits and vegetables), olive oil, fish, dairy products that are low in fat and moderate wine consumption has been associated with low prevalence of food".

The study, 180 people suffering from metabolic syndrome at random, they were divided into two groups, a follow-up by the Mediterranean diet and the other continued prudent diet (generally low levels of fat and low in refined carbohydrate). 90 People in the Med diet, 78 people have been cured of all symptoms have metabolic syndrome.

Some parts of the Med diet that appears to reduce the metabolic syndrome are:

N-3 fatty acids and fish consumption

Olive dairy

Low oil

Low-fat

Glycemic Index and an increase of intake

Moderate wine consumption

Whole grains

Fruits and vegetables

Nuts

proteins


All these foods are for the most healthy and natural food.

What the research really shows is that, after that a healthy diet can quickly reduce the risk of developing type 2 diabetes. When diabetes is defined, it is very difficult to control. There are many serious problems to health associated with type 2 diabetes, amputations to increase the risk of diseases of the heart and the damage to the nerves, impotence and kidney damage and blindness.

Once more, the key is to eat a balanced, healthy diet and getting regular exercise.

How to lose weight with diet only

No exercise required

Regular, combined with healthy exercise is the best way to lose weight, however, often people could not exercise such as regularly for various reasons. Therefore if you are not able to exercise, a healthy weight loss diet plan should be adopted to help you lose weight and then to control your weight.


How diet can lead to weight loss?

To lose weight the only thing that we need to do is to ensure that the daily caloric intake is lower than our daily caloric needs.


Why exercise is so important for losing weight?

Exercising it regularly makes it easier for four main reasons:


It increases the amount of calories you burn while you're exercising.


It increases your metabolism as your body creates new muscle tissue


It enables you to manage the appetite for the release of hormones that inhibit hunger


It uses glycogen reserves that triggers the hormone called glucagon from the burning of fat.


So if you can not exercise you are missing a great advantage when it comes to weight loss. However, it is still possible to lose weight.


How to lose the right type of weight?

Where things become more complex, it is to ensure that you would lose to the right type of weight. Everyone wondered "how to lose weight?", but the real question should be "how to lose body fat while maintaining lean muscle tissue."


Muscles are essential for good health. Not only do they make you stronger, they also help keep your metabolism high. Tissue muscle is very "hungry", carbohydrates and proteins for growth, repair and operate and need much more energy for adipose tissue. Another way to explain it is that the muscles are the engines of the body, fat cells are fuel storage tanks. When someone wants to lose weight, they really want to lose fat.


The problem of very low calorie diets

The problem is that when people try to lose weight with diet, they only usually dive into a low-calorie diet, or sometimes a diet very low in calories (referred) which is defined to be less than 1,000 calories per day. Often, these plans do not provide the body with enough protein to maintain muscle tissue and muscle atrophy occurs as well. The body breaks down simply due to our own muscle tissue to provide energy for the other parts of the body. There is also loss of fat, but not in isolation.


Some biology: the relationship of food, storage of fat and hormones

To understand why in this case, we need to explain a little about how the body stores fats then burn. Stakes are two hormones in the body that control the storage of FAT: insulin and glucagon. Both are enabled by changing glucose levels in blood (blood sugar).


When we eat carbohydrates, particularly high-GI carbohydrates such as bread, it increases the level of sugar in the blood. This increase triggers a release of insulin in the liver. The function of insulin is reduced blood glucose levels (long levels leads to health problems). To this end, to help the absorption of glucose in the storage of fat (adipose tissue). Glucose is actually transformed into glycerol and combined with fatty acids to tag (triacylglycerols) and this is what we call "bold".


So, in short, when we eat sweet foods our bodies release insulin which causes that the sugar is stored as fat.



Therefore, what are the causes that you burn fat?
When blood glucose levels fall, the liver releases glucagon. The role of this hormone is simply to inverse of the rate of sugar in the blood so insulin will rise again. Glucose is the main source of power of the brain which is our main body that controls the functions of all other parts of the body.


So primary target of glucagon ensures that the brain is supplied with sugar. This is accomplished by breaking the adipose tissue to extract the sugars in the tags (pause and fatty acids). This is what we call the burning of fat.


It is not easy to get the body to release glucagon well. You should rate sugar in the blood at very low levels. As soon one eats sugary foods, like some bread, pasta, vegetable like parsnips and squash, high breakfast cereals, processed rice, any junk food (cakes, cookies, Donuts), the blood sugar rises and glucagon production stops and takes insulin, so you pass a light of the situation to store fat.


This is why the unhealthy diets can therefore can lead to weight gain, most of what is healthy also is high on the Glycemic Index (high GI) which means causes spikes of sugar in blood, insulin and fat accumulation, thus limiting the high GI foods can help to lose weight with diet only.


The importance of proteins

Protein is important for two reasons:


Without enough daily wear early as blocked amino acid in muscle tissue protein muscles are used to help with the permanent repair of vital organs.Where is the digestion of proteins that the body releases another hormone, PYY, eliminating hunger.


This is another reason why very low calorie diets are bad, the people who consume less than 1000 calories per day to lose weight often consume enough protein, instead, only eat their favorite sugary snacks. The sugar regimen heavy not only causes fat store but also the absence of protein cause muscles from waste and reduces BMR (metabolism unit) which determines the amount of energy used to maintain the body at rest.
