Obesity What are the risk factors
Lifestyle very early influence the risk of obesity.
Several factors have been identified: sleep time, time spent watching TV, standard growth curve, fast fat grain ...
They are identified in the first years of life.
Childhood obesity and the environment: the link is here
The environment is very early and plays a decisive role in the development of childhood obesity. The early identification of factors that promote excess weight makes a suitable and effective prevention.
A study conducted from 8000 children aged 7 years and followed from birth, allowed to list many risk factors for obesity, identifiable during infancy.
Of course, a high birth weight and parental obesity increase the risk.
A genetic mechanism, family environmental or dietary habits can be the cause.
But other environmental indices were also recorded as the duration of sleep: sleep and less than eleven per day at the age of three years favors the appearance of excess weight.
Hormonal factors, late food intake or lack of physical activity can play an important role.
Time spent watching TV is also implicated, even among the very young. Thus, from the age of three years, a child who spends more than eight hours a week in front of the screen has a high risk of becoming obese and 7 years.
Other risk factors for obesity
Continuing finer analysis, the authors identified other risk factors:
an early difference between 8 and 18 months, compared with the growth curve;
a rapid gain of fat tissue before 4 years;
a high weight gain in the first year of life.
Two other factors can not be ignored: the protective effect of breastfeeding and diet appropriate to the age of three years.
Conclude to better prevent obesity in children?
In conclusion, there are many signs that must be identified early childhood to adopt preventive measures, all the more effective they will be in place early, before the extra pounds will be installed.
Its worth to be vigilant (e) and talk to his doctor or pediatrician at the first warning signs!

Gut Flora Disease and Obesity
---the other 200 posts---
The health of your gut flora (the interacting trillions of bacteria of a couple of hundred different species that make up the pound of bacteria that you carry primarily in your large intestines) is more important than your genetics to your overall health. Thus, your health is a result of diet, gut flora adapted to your diet and exercise. Everything else, your genetic risks, environmental toxins, etc. are of only minor impact.
I am trying to paint the big picture of how the food that you eat and your gut flora interact to determine your health, by which I mean whether you get sick, become obese and/or bloat with gas.
Health Depends on Gut Flora
If you are healthy, you have a couple of hundred different species of bacteria that help you to digest the protein, fats and carbs that you eat in meat and vegetables. Your body easily digests protein and fats in meat, fish, eggs and dairy, because enzymes to digest them are present in your stomach and small intestines. The only carbs that your body can digest are some simple sugars and starch. The rest of the polysaccharides present in plants cannot be digested without the help of bacteria. The polysaccharides that your gut flora can digest are fermentable, soluble fiber, e.g. resistant starch, pectin, inulin, arabinogalactan, xylans, beta-glucan, etc. If you can’t digest soluble fiber, because you have damaged gut flora, dysbiosis, and are missing essential bacterial species normally found in a healthy gut, then the soluble fiber just passes through as insoluble fiber and readily dehydrates into hard, constipated stools. Partial digestion due to just a few missing bacterial species produces the symptoms of food intolerances.
Constipation Results from Dysbiosis
The bottom line is that the volume of healthy, soft, firm stools is made up of gut flora that digested dietary soluble fiber and converted it into more bacteria. If you eat more soluble fiber, this food for your gut flora, will produce proportionately more bowel movements.
Gut Flora Guide Immune System Development
Most of cells of your immune system are in the lining of your gut and there are particular species of gut bacteria directly involved in the development of immune cells that have different functions as they spread throughout your body. Some of these cells are aggressive and attack pathogens, while others make sure that the aggression doesn’t get out of control and cause autoimmune diseases or allergies.
Gut Flora Divided into Groups to Show Involvement in Disease
Recent studies have demonstrated the role of gut bacteria in producing nutrients, vitamins and neurotransmitters. To highlight the essential role of gut flora in disease, I have divided the hundreds of species of gut bacteria into groups to illustrate their direct involvement in development of the immune system and regulation of the flow of dietary nutrients involved in obesity. A recent study shows that an infection can produce a change in gut flora associated with marshaling additional fatty acid nutrients for the host instead of just producing more gut flora. Chronic change of gut flora in this way leads to obesity. Other types of dysbiosis contribute to infections, cancer, autoimmune disease, allergies, food intolerances, gas and bloating.
Group A Bacteria Provide Aggressive Immunity
There are several dozen species of bacteria in healthy gut flora, including the filamentous bacteria, that trigger the development of the aggressive part of your immune system that attacks pathogens, and kills cells of your body that are infected with viruses or are cancerous. Most antibiotics don’t permanently damage this group of bacteria, so after a course of antibiotics you can usually still stop infections. Excessive suppression of aggressive immunity contributes to cancer.
Group B Bacteria Provide Suppressive Immunity
There are dozens of other species of bacteria, including Clostridia, that control the development of the suppressive half of your immune system that produces immune cells, such as regulatory T cells, Tregs, that stop the aggressive cells of your immune system from attacking your own cells and innocuous things such as food and pollen. Many common antibiotics damage these species of bacteria and are thought to contribute to the development of autoimmune diseases and allergies. Inflammatory bowel disease is characterized by a simplified gut flora with only half the healthy number of bacterial species. Resistant starch preferentially feeds these bacteria to enhance suppressive immunity and in some individuals cure autoimmune disease.
Group C Bacteria Convert Soluble Fiber to Short Chain Fatty Acids (SCFA)
The fermentable soluble fiber in your diet is typically from vegetables and it is converted by the largest and most diverse group of bacterial species into short chain fatty acids. Each different plant polysaccharide, and there are hundreds, requires many enzymes for complete digestion to the simple molecules used by the bacteria to make its own proteins, fats and polysaccharides. Absence of bacteria that are specialized for the digestion of particular polysaccharides or other dietary components can disrupt gut flora and cause digestive disturbances that are experienced as food intolerances (also confused with food allergies that are rare.) Some of the bacterial species convert polysaccharides into butyric acid and other short chain fatty acids that are the major source of energy for cells that form the lining of the intestines. These SCFAs are also a major food source for other gut bacteria.
Group D Bacteria Convert SCFAs to Fecal Bacteria to Produce Bulk of Bowel Movements
In healthy people, the SCFAs produced by gut flora feed the intestines and the remainder produced in the large bowel is converted into more gut bacteria, which forms soft stools. Antibiotics typically damage these bacteria and result in constipation. These bacteria are typically more sensitive to antibiotics than those that digest the soluble fiber and produce SCFAs, so the excess SCFAs pass into the blood stream and contribute to obesity instead of stools. Lean mice with gut flora exchanged from obese mice, become obese. Cattle are fed antibiotics to enhance the conversion of corn polysaccharides into SCFAs and body fat prior to slaughter.
Group E Bacteria convert Soluble Fiber to Methane and Hydrogen, Bloat
Increased volume of the intestines, bloating, results from conversion of soluble fiber into methane, hydrogen and carbon dioxide gases. Some of this gas is absorbed into the blood and can pass from the large intestines, through the blood, and back to the stomach and small intestines. Helicobacter pylori, the cause of stomach ulcers and gastric cancer, can utilize hydrogen from the blood as an energy source.
In Summary:
A+B+C+D = healthy, normal weight
A+C+D = normal weight, autoimmunity and allergies
B+C+D = normal weight, susceptibility to cancer, chronic Lyme disease, food poisoning
A+B = normal weight, constipated
A+B+C = obese, constipated
A+B+D = normal weight, food intolerances
A+B+C+E = obese, constipated, bloated
Cure for Dysbiosis and Associated Diseases is Repair of Gut Flora
The excitement about the use of resistant starch (RS) and probiotics with Clostridia and other soil bacteria to reverse the symptoms of autoimmune diseases is based on the ability to repair gut flora damaged by poor nutrition and antibiotics. Low carbohydrate diets that do not provide soluble fiber to feed gut flora lead to dysbiosis and chronic diseases. Resistant starch, as the name suggests, passes on to the colon by avoiding digestion with amylases in the small intestines and acts as a soluble fiber to feed gut flora in the colon. Clostridia convert the RS to sugars and SCFAs usable by other gut flora. Note that some species of Clostridia produce toxins and it is these pathogens that take over in hospitals after the healthy species are killed off with antibiotics. Fecal transplants are the best treatment for these hospital acquired infections.
I have discussed the role of hygiene, muddy veggies, fermented foods, etc. in several other posts on repair of gut flora.
Complete repair of gut dysbiosis is possible, but it requires more than just changes in diet and dairy probiotics, as typically recommended erroneously by the medical industry.
Health is dependent on:
- an Anti-Inflammatory Diet,
- gut flora adapted to your diet
- exercise and
- adequate sleep
The rest (genetics, vegan vs. paleo, environmental toxins, organic veggies, GMOs, etc.) are minor contributors, less than 10% in aggregate, to overall health.

Abdominal obesity is the biggest enemy of your health! life diets
Abdominal obesity is the biggest enemy of your health!
Abdominal obesity appears in two different forms. The first figure is the fat under the skin. The second is fat guts. They are found around the internal organs, which is the real enemy of health!
Thursday, May 2, 2013 fight against abdominal obesity
Abdominal obesity and health
How much should be weighed, Doctor? Its a common question, an important question. It is common because two-thirds of Americans weigh more than what should be their weight. It is important because excess weight goes to what is beyond the distortion of body shape. fats:
Responsible for high levels of cholesterol low-density proteins ("harmful") and triglycerides.
Reduce cholesterol high-density proteins ("good") at the same time.
Disruption of the bodys response to insulin, which leads to higher levels of blood sugar and insulin.
Contribute to the major causes of death and disability, including heart attacks, strokes, high blood pressure, cancer, diabetes and inflammation osteoarthritis, fatty liver and depression.
Responsible for approximately 1,000 deaths in the United States every day.
Given these risks, it is not surprising that you want to find out how much should be weight. But this question is common and what is important is in fact the wrong question. For health, the problem is not in how much is your weight, but in the level of abdominal obesity that you have.
Increase the size of the abdomen
During the past few years, attracted a number of studies of attention to the importance of abdominal obesity. Some research showed that abdominal obesity is a predictor of danger factor, more than body mass index (BMI).
For example, a study in 2008 conducted on 245 533 dollars that large waist circumference was associated with an increased mortality rate, even in people who have a normal body mass index (BMI). Another study showed the 2,229 victims of heart attacks that patients with large waist circumference had a higher rate of death, so that they have a low body mass index (BMI).
Deficiencies in body mass index (BMI)
Although the body mass index (BMI) is the official standard, but has several disadvantages.
Athletes professional people with big muscles and a few body fat can have a body mass index (BMI) of up to 32.
Perhaps BMI fails in that accurately reflects the level of body fat in adults who have lost a basic amounts of muscle.
The most important problem is that BMI reflects the level of total fat in the body without considering how to distribute these fats. Although there was no increase fat good, but the increase in abdominal fat is the worst case.
What makes abdominal obesity is very harmful? Scientists do not know why is certain, but new research offers important interpretations.
Abdominal obesity appears in two different forms. The first picture is of fat under the skin, which is located just under the skin. These fats behave the same fat found everywhere in the body. Its not friendly to your health, but it is not a source of danger particularly well. The second type is fat guts. They are found around the internal organs, which is the real enemy of health. Why?
Interpretations of early the entrails obesity was associated with excess activity of the bodys response to the pressure, making it produces large amounts of stress hormones, such as adrenaline and cortisol.
There latest interpretation says that the entrails fat cells release their metabolic products directly into the blood that goes directly to the liver. As a result, the entrails fat cells that grow and are filled Balglsaredat triple pour excess free fatty acids in the liver (all fat is made up of free fatty acids). And this can be toxic to the liver. And free fatty acids accumulate also in the pancreas, heart and other organs, where it caused damage.
A third theory shows the complex nature of the fatty cells. The scientists believe that fat cells are just a place to store excess calories in the form of fat. But it is now clear that in addition to storing excess energy, fat cells produce a large number of proteins that enter the bloodstream and affect other organs. Some of these proteins leads to damage, and others can be protective. And entrails fat cells produce many harmful substances, with a little bit of useful material.
Measurement of abdominal obesity
The most accurate way to measure obesity entrails are imaging computed tomography (CT) or magnetic resonance imaging (MRI). However, the much easier way is to determine the ratio of waist to hip circumference. But many experts have turned up to a simpler method: measuring waist circumference.
To measure your waist circumference properly, you need a tape measure clothing stainless stretchable, not metal measuring tape drive.
GIVE your shoes stop with the put your feet next to each other.
Make sure to have your belly naked. Relax and exit . Not Pull exhalation the belly inward, it may give you better figure but will not improve your health. And the use of belt size instead is unrealistic.
Measure the circumference of your waist at the navel. And make sure you make the tape parallel to the ground. And record the measurement in inches with rounding to the nearest ten, and then repeat the measurement to make sure you are set correctly.
Check the table below to know what means the circumference of your waist for your health.
Waist circumference control
So, what can you do to reduce your waist circumference? You must forget the tummy tuck. Its good to increase the strength of the abdominal muscles, which may improve your health, but it does not burn abdominal obesity are optional. Tools that are reducing the fat is the worst, too, because they waste time and money without the lead to reduce the circumference of your waist.
You must forget liposuction. That surgery can remove fat under the skin of your torso, but not fat guts. Cosmetic surgery will improve your appearance and reduce your waist circumference, but will do nothing for the metabolism in your body will benefit your health.
Remember basic things. The only way to reduce the fat guts are losing weight, and burn more calories - by exercise - so that the amount of burning more calories that are ingested through food. Continuous weight loss requires reducing calories while increasing exercise. Here are some tips:
Reduce the amount of food in your meals.
Choose your wisely foods. And avoiding foods high in sugar and / or fat. It is caloric-ally dense, and slip into your stomach very easily. Instead, eat fruits and vegetables and whole grain products. Its high dietary fiber, and you need a longer time to eat, and probably Chbek more. Piece of chocolate, medium-sized and medium-sized apple, both of which contain about 100 calories (if already medium-sized). Now the thought of eating 5 pieces or 5 apples. It is clear that most people can easily eat the pieces, however, only few can finish eating all five apples.
Exercise more from the exercise. Walking two miles a day will significantly reduce the risk of heart disease, stroke, diabetes, high blood pressure and early death. It will also burn calories. The man who weighs 200 pounds will be used about 220 calories in 30 to 40 minutes of brisk walking. That alone means the loss of about 30 pounds in one year - without any nutritional changes. The exercises also help in maintaining weight loss, unlike popular diets significantly. Secondly, it will burn excess abdominal fat, which is the thing that never does a tummy tuck and ways to reduce fat in certain areas.
In order to lose weight fast, each less and exercises more.
Male body shape
Abdominal obesity has many other names, including obesity, the upper part of the body, stem obesity and central obesity and obesity entrails. In terms of more versatile, also known as the belly of cola and shape of the apple and alternative cupboard. And thats where this type of fat distribution more common in males than in females, perhaps known as the male body shape.
According to the name, abdominal obesity is a form of risk - and abdominal obesity are increasing even faster than the body mass index (BMI) in our society. But by using a simple program of diet and exercise, can men with apple shape to lose weight. If you change the the "alternative Dolapk" will maintain your health.
