A team of scientists in Britain examined three hundred people who became severely overweight at a very young age. They did this to determine whether a faulty gene was involved. Researchers were looking specifically at the gene in charge of what is known as the leptin receptor. Leptin is a hormone that controls appetite and can influence how much we feel like eating or overeating. It has been previously implicated in animal obesity research studies.
Scientists examined the obese study participants to see whether this so-called obesity gene was disturbed in any way. They found that only 3 percent of people had an abnormal leptin gene — indicating that leptin is probably not a factor for most obese people. And scientists in New Zealand are dispelling the common myth that obesity is caused by “bad genes.”
In what is referred to as a burst through discovery, scientists from Auckland University’s Liggins Institute have found that genetic pre-disposition to fatness can be reversed through good quality nutrition in early childhood. Their studies shows that when a mother is undernourished, her child’s body is pre-set to cope with a life of scarcity-the energy-dense fast food diet of the Western world results in kids who are likely to become fat and obese. This is from poor diet and nutrition.
In laboratory tests, newborn offspring from both well-fed and undernourished rats were given leptin, a hormone that signals to the body when it has eaten enough. When they became adults, the long-term effects were measured by looking at genes that regulate metabolism in the liver. Rats from well-fed mothers reacted to leptin in the opposite way to those from undernourished mothers.
The researchers urge mothers to eat a more balanced diet (with the right amounts of protein and vitamins) during pregnancy. However, if the fetus is undernourished in the womb, the long-term effects can still be corrected through good nutrition.
So what’s the final word on all this? Is it our genes that make us easily gain weight which leads to becoming overweight or even obese or is it our behavior that shapes (and sculpts) our bodies? The most likely correct answer is: BOTH. You are born with a set of genes you cannot change. Some people can eat and eat and never gain a pound. Others can’t. But as the recent research is showing – you have much more control over the final outcome than most people are willing to take credit for. No matter your genetic make-up, you can choose to eat properly and exercise.

Excessive weight leads to obesity and is debilitating. There are a number of associated health problems such as heart disease, diabetes, stroke, high blood pressure, certain type of cancer and osteoarthritis. Excess weight and expanding waist denies you the pleasure of being agile, light and energetic. An overweight person gets easily tired and finds movement difficult. Weight loss is possible when there is a loss of body fat, fluid, and deposits in the tendon or other connective tissue. One may intentionally lose total body mass to be physically fit or improve appearance or health. Such weight loss can decrease the possibility of being afflicted by disease. There are many ways one can lose weight.
The most common of all methods to lose weight is by changing the eating habits so that calorie intake is reduced. Physical exercise and increased physical activities are yet another method. Medicines, herbs and food supplements are also used so that appetite decreases, volume intake is reduced or the absorption of fat is even blocked. There is a booming weight loss business. They offer crash diet courses, physical fitness programs and medication. There are crmes, CDs, books, body belts, pills, lotions food products and supplements that are available in the market. Fitness centers, weight loss groups and weight loss specialists have sprung up. All these can be expensive. Most resort to self-help and take to diet and fitness plans. Only when these do not help do they resort to the assistance of professionals.
A number of weight loss diet plans are available in the market. Some of them are The Atkins diet, the 7 day diet, NutriSystem, Anne Collins Weight Loss Program, Beverly Hills Diet and Diet Smart. It is not as though all diet plan programs may suit you. You need to plan your diet that best suits you personally as are offered by Ann Collins’ Weight Loss Program. Nine diet options are offered in the nine manuals under this program by Anne Collins, a nutritionist and weight loss consultant. These manuals can be bought online and downloaded in e-book format.
However, there is no one sure way to lose weight. Each person has to work out ways to counter the cause of weight gain and to lose excess weight.
Losing weight is not at all easy and it may be tiring as well. Thus, determination is always necessary in losing weight.

The spread of the problem of overweight and obesity has been so much that it has now come to take a top slot amongst the health concerns worldwide. Not long ago it was presumed that this problem afflicts only the richer sections in the society. But it is now evident that it has afflicted the poorer sections in the affluent countries. It is also a phenomenon amongst the affluent in the developing countries. The role of diet and lifestyle in obesity is clearly indicated. The people in affluent countries consume more carbohydrates when compared to fat. Sweetened beverages are the main source of increased consumption of carbohydrates. A quarter of the calorie consumed by the adult population in the United States comes from consumption of beverages. There has also been an increase in the calorie content in the fast food that is available for consumption over time. While consumption of fast food increased three times, the calorie consumption from fast food was four times in the last two decades. The increased calorie intake amongst the population is the major cause of overweight and obesity.
There has been a shift from fresh food to processed food. The improved agricultural techniques and support to agriculture in terms of subsidy has lowered the food prices in the United States in such crops as wheat, soy, corn and rice. Production of these food crops has also generally increased. All these have in turn made possible cheap processed food. In comparison, vegetables and fruits are costlier.
Along with the rapid rise in the overweight population, there has also been a growing weight loss market where various weight reduction regimes and prescriptions are available. Combating obesity has also become professionalized. Expenditure on weight loss programs have been increasing in leaps and bounds. The investment in research and search for effective remedies has increased with the high demand. The research has been both into the psychological cause of obesity as well as weight loss remedies. Shrink Yourself by Roger Gould for instance explains the emotional basis of over eating.
There are many diet regimes, pills and capsules, physical exercises, herbal remedies, drinks and shakes, professional experts and fitness centers. It is necessary to evaluate these remedies in terms of which could be most suitable for you. You could also seek the help of an expert to help you decide.
Amidst the wide choices of diet regimes, quality should always be your determinant. By looking into quality, your body will only be taking in the good ones.
