Obese people six times more likely to get gullet cancer than normal weight people, according to a study published in the British journal “Gut”. Obesity and gastric acid reflux are major risk factors for developing esophageal cancer. Combination of both factors will increase gullet cancer risk by 16 times. Highly obese people with body mass index (BMI) of 40 or more are at very high risk of developing gullet cancer than people with a BMI of between 18.5 and 25. Obesity is the second most cause of cancer while smoking is the most common cancer cause. Obesity is also responsible for diabetes and heart diseases. United States of America is the number one country in obesity. How does Obesity raise cancer risk? 1. Obesity increases insulin level in the body which raises production of insulin-like growth factor. 2. Both hormones stimulate cell proliferation and inhibit apoptosis (cell destruction). 3. Above 2 causes are triggers for cancer development. Obesity is already reaching epidemic proportions even in children due to junk food eating habits and lack of exercise. Obesity “time bomb” will explode at any time. … [Read more...]
How to control Obesity epidemic?
Obesity is gradually attaining epidemic proportions not only in developed countries but also in developing countries. People are getting obese cutting across country, class, economical status and region. Lack of physical exercise, junk food habits, lack of awareness and advertisements are fuelling the growth of obesity. Surprisingly, obesity is rapidly growing in low to middle income families due to use of cheap junk foods. Obesity causes more than 50 diseases of which Diabetes, heart disease and stroke are major ones. It is very difficult to control blood sugar and blood pressure in obese patients. They gradually develop metabolic syndrome and insulin resistance if they failed to control their weight. How to control Obesity? 1. Exercise for 30-45 minutes is best. Brisk walking is ideal and simple exercise to control one’s weight. 2. Eating diet rich in vegetables and fruits is good. 3. Stay away from fast foods which are rich in unsaturated fatty acids. 4. Never skip breakfast. 5. Stay away from soft drinks and other high calorie diet. 6. Encourage children to play physical games than computer games. 7. Schools should not allow the vendors to sell soft drinks and fast foods in their campuses. 8. Parents should control TV watching habits of children. 9. Governments should levy higher taxes on junk foods and high calorie drinks. Controlling weight is in our hands. We just need determination to control this epidemic. … [Read more...]
Food Craving- Beware of that temptation
Some persons have got no feeling of appetite, but, they still have the desire to eat some sort of food items. This sort of situation is known as “craving”. So, they take either chocolate or ice-cream or pizza or chips and afterwards they obtain some sort of mental satisfaction and jolly mood. Mainly, women prefer to take this sort of “ready to eat foods”, where as men like to have foods prepared at home. 92% of females are showing interest in taking ‘chocolates’’. But tastes may change depending on the moods. Causes for food craving: 1. Anxiety and tension: Craving is more in these types of persons suffering from anxiety, etc. These individuals exhibit keenness to take more sweets and fatty foods. When persons are under stress conditions, some chemicals are released in their brains, and in order to get relief from the stress, they go on eating and obtain calmness. Moreover, they do not take into consideration, the quantity of food they are taking. There after they put on excessive body weight and become obese, within no time. As, the foods containing more carbohydrates, if taken in excess amounts, can not be digested by the body so easily. 2. Hypoglycemia: some times, the blood glucose levels fall into below normal levels and leads to craving. 3. Meal timing: The time schedule between breakfast and lunch or the gap of time between two main meals is five (maximum 6) hours, not more than that under any circumstances. But, if the time -gap is more, it leads to craving. 4. Changing in hormone levels: It is more commonly seen in females (than males). Especially, during pregnancy and also before monthly menstrual cycle periods, the change in hormone levels in females, have effect on their food habits and prone them to eat more. How to control this habit of "craving for food”? 1. Never Miss break-fast or main meals. 2. Take foods (not oily fatty, and sweet food items), containing less calories for every three hours. Prepare the diet-planning, so that the feeling of appetite cannot arise. By taking less amount of food at frequently (not more in quantity at a time), so that the blood glucose levels do not rise and be kept at normal levels. 3. Take foods containing more fiber and also fruits. 4. Take less salt and sugar, otherwise, they create temptation to eat more. 5. Reduce the habit of going to restaurants or fast-food centers. 6. Not stop taking the chocolate or ice-creams or any other food item you like altogether, but take rarely, that is weekly once that too a small piece. 7. After taking some food item, if you wish to have it more, take two glasses of water instead of that food item, as sometimes we mistake thirst for appetite. 8. Do walking or play with children, whenever you feel the sensation of craving. 9. Taste and smelling technique: If you still have the feeling of craving, feel the smell of banana or peppermint. By inhaling the smell of vanilla, the desire of taking sweets will gradually diminish. Continue this for one month; the desire for craving sweets goes away for good. The result is you lose the excess body weight. The golden rule is: "Where there is will, there is a way’’. … [Read more...]
Obesity Research: Cold virus may cause Obesity
A common virus, causing cold can be a factor causing obesity, according to a study conducted at the Pennington Biomedical Research centre at Louisiana State University in Baton Rouge. The researcher further says that “virus is not the only cause of obesity but this study provides stronger evidence that some obesity cases may involve viral infections.’’ The adenovirus-36 (AD36) has already been implicated at the cause of weighting gain in animals, and with this study also, researchers showed for the first time that it can also cause humans to pile on the pounds (kilograms). These findings could accelerate the development of a vaccine or an anti viral medication to help fight the battle of the bulge, alongside the diet and exercise which the other factors are causing obesity. A previous study showed that 33.3% of the obese people are infected with the virus, compared to their linear counter parts who are 10% affected. In laboratory experiments, it is found that the bug appeared to promote the formation of fat cells from stem cells. The team took adult stem cells from fatty tissue left over from patients who had undergone liposuction (a procedure to remove fat from the body), and exposed some of it to AD-36, leaving the remaining cells untreated. They are allowed to grow in a tissue culture for a week of time, most of the virus-infected adult stem cells developed into fat cells, (where as the untreated cells did not develop in fatty cells). The researchers further says , “it is not clear what drives the transformation, how long the virus lingers in the human system or whether its fat-enhancing effect continues after the body has cleared the virus.” As the research is going on, the real mechanism will be revealed in the near future. As usual we should always keep in mind the other factors that cause obesity like, Lack of exercise, Excess food intake, Depression (sometimes the patient takes extra food to combat depression), etc. If it is true, it may be difficult to control Obesity. Obesity is a major factor in causing Type2 Diabetes, Coronary Heart disease and other lifestyle related chronic diseases. … [Read more...]
Relation between waist line and Obesity
Researchers say that a quick check around the waist with a tape measure may be a better way of telling, if anybody is at risk of heart disease, than stepping on a scale. People with larger waistlines (even if they are not overweight), are more likely to show the early signs of heart disease, than those with smaller waists. Quote on waist line significance: “Inches are as important as pounds or kilograms (of bodyweight)”. The team of researchers used the methods like, -Magnetic resonance imaging -Electron beam computed tomography scans Several studies showed that-waist size is clearly linked with -Heart attack -Stroke -Heart disease risk. Government of America gave the following guidelines: -Men should aim to have waist of 40 inches (102cm) or less, in circumference, -Women should have 35 inches (89cm) waist line. The researchers found no absolute cut-off but found that “the smaller the person’s waist, the clearer his or her arteries were observed to be.” -High cholesterol level, High blood pressure, Lack of exercise, etc, are other known risk factors for the chances of having early artery clogging. Weight alone does not do early artery clogging, but waist size does have much effect on artery clogging leading to heart ailments. So the golden word is: “the longer the waist line –the shorter the life line.” … [Read more...]
Obesity: Statistics, causes and diseases
Obesity and overweight together constitute as one of the top 10 global health problems as per the recent surveys conducted by the World Health Organization (WHO). Obesity Statistics: 1. Overweight adults in the entire world are: One billion (one hundred crore). 2. Children (under five years of age): more than 22 million. 3. By 2015 approximately overweight persons will be: 2.3 billion (230 Crores). 4. Obese people in 2007: 300 million (30 Crores). 5. By 2015 obese people will be: 700 million (70 Crores). 6. Obesity is a problem not only in developed but also in developing countries, where at present 115 million (11.5 crore), people are affected. Obesity is an abnormal and excessive accumulation of fat mass in the body. Over weight and obesity in adults is calculated as follows: The body mass index (BMI= Body weight(in kg), divided by the square of the height(in meters). "Overweight" in adults is defined as, when BMI is greater than or equivalent to 25 and "obesity’’ as when BMI is greater than or equivalent to 3o. Basic mechanism behind Obesity: The hypothalamus, a region in the brain, regulates food intake and the metabolism process in the body. Lack of balance between calorie intake (over eating) and physical activity (less spending of calories) is the reason for Obesity and Overweight. Then the caloric surplus is converted in to fat and stored in the body as adipose tissue. Overweight and obesity are complex problems depending upon many factors. 1. Genetic factors: The first recessive gene involved in obesity in mice and humans was identified by Prof. Jeffrey Friedman in 1994. Today, five mutations of this gene have been identified. It appears that predisposition to obesity is caused by a complex interaction between at least 250 obesity– associated genes. This would mean that people are not equal in their risk of developing obesity. 2. Nutritional factors (in perinatal period): phenomenon called “Metabolic programming or Metabolic imprinting” during early life ,may modulate later obesity risk. 3. Life style factors: With more number of people consuming energy-densed food and eating often in the day, without hungry, is causing obesity. 4. Sedentary life: Today people are leading sedentary lifestyle than did their hunter-gatherer ancestors. Risks or diseases due to obesity are: 1. Type-2 diabetes 2. Cardiovascular (heart) disease 3. Rising of blood pressure (BP) level 4. Strokes 5. Certain types of cancers, etc. Always keep in mind this golden word: “Longer the waist line- shorter the life line”.

Obesity: Causes and effects on the body
Obesity Statistics: Incidence: As per the W.H.O. report, 30% of the people in western countries are suffering from obesity. Out of the 6 billion people in the world, 1 billion are obese people. The other side of it is 1billion people are without sufficient food and living in poverty. Obesity epidemic is gradually on rise in developing countries also due to fast growing economies. Obesity Causes: 1. Modern life: Due to sedentary habits with little exercise is the main reason behind increased incidence of Obesity. 2. Fast food restaurants: These restaurants are growing in number in leaps and bounds. People are taking more junk and fatty foods. Due to these diet habits, more fat is stored in the body causing obesity. 3. Alcohol causes fatty liver and thereby more fat is stored in the body. Patient becomes obese. The main trouble with many people is they consider obesity as a cosmetic problem rather than disease. But the truth is obesity is a chronic disease due to deposition of more fat in the body. The important thing is over weight is not a disease but obesity is a disease. But the line of differentiation between the two is very thin. 4. Experts opinion: A famous doctor says that obesity simply a bad news for both body and mind. Another doctor says: Asians have more body fat, is not that they eat more but move less. 5. Other Causes of Obesity: A. Increasing affluence B. Little outdoor activity C. Spending more time watching television and playing computer games. 6. Emotions: Can they cause obesity, but how? People tend to eat more, when they are; 1. Upset 2. Anxious 3. under stress 4. Feel boredom. To quell these feelings they eat more. This becomes a vicious cycle. 7. Hereditary: Small parts of the DNA that people inherit from their parents that determine the weight gain in them. These genes do not tell our body how to utilize extra calories. 8. Nutrition and pregnancy: One theory is that when children are under nourished in the womb of their mother, when become adults, they usually develop abdominal fat, even with the normal diet. This put them at greater risk of obesity related illnesses. 9. In Asians: Asians evolved a so called ‘’thrift gene’’ after living for thousands of years under near-famine conditions. Their bodies are, paradoxically, metabolically, efficient to deal with the relative abundance of modern life. It is a genetic trait. Effects of Obesity on the body: Obesity causes following diseases: 1. Diabetes 2. Heart problems 3. Rise in blood pressure 4. Incidence of some cancers is more in Obese people. How to control Obesity: 1. Doing exercise – Walking is the best and simple exercise. 2. Eat more fruits and vegetables 3. Taking less fatty foods.4. Meditation and Yoga 4. Controlling stress and strain … [Read more...]

Facts about Fats
Fat in our body is also called lipids. Fat diet is the major cause for Obesity and Over weight. Types of Fats: Fats are 2 types. 1. Saturated fats 2. Unsaturated fats Unsaturated fats are of 2 types. 1. Mono unsaturated 2. Poly unsaturated At normal temperature, saturated fats are in solid form while unsaturated fats are in liquid form. Fate of fat in our body: IS it good to take more fat in our blood? 1 gram of fat gives 9 calories of energy. Usually body takes the necessary energy for its functioning of routine body activities from fruits and cereals etc. Body utilizes fat as a second alternative only. Hence fat accumulates in the body due to non use in the first phase. After entering into stomach, fat is broken down into fatty acids and glycerol. Fatty acids break into fat globules which gives immediate energy. The excess fatty globules again converted to fatty acids and stored under the skin and around certain organs. Some fat converts to glycogen to be utilized for immediate energy. 1 gram of carbohydrate gives 4 calories of energy. So, accumulated fat causes overweight which in turn leads to diseases like 1. Diabetes 2. High blood pressure 3. Bronchial Asthma 4. Bronchitis 5. Skin thickening Fat in males and females: In females, fat is present more in buttocks and thighs. In males, fat is present around umbilicus (abdominal area). Increase in fatty diet is mainly due to fast foods. Take more fruits and green leaf vegetables.
