Obesity can be defined as a body weight that is greater than 30% above a favorable target weight. Culture has often blamed obesity on the individual. We assume that people are overweight because of personal failings.
Obesity has affected so many Americans, it has reached epidemic levels.
There are a number of contributing factors to rapid rise in obesity, WF health experts uncover some major causes.
1. The Gene, GAD2 :
According to the lead researcher Professor Philippe Froguel (from Imperial College London), obesity is a complex problem, which could not be entirely explained by one factor alone. But he said GAD2 may be responsible for obesity in about one in ten seriously overweight people. The Imperial study, of more than 1,200 people, identified two forms of the GAD2 gene. One protected against obesity, the other made it more likely by stimulating the appetite. Thinner volunteers were found to be more likely to carry the protective form of the gene, while the other version was more common in obese people. It seems to stimulate overeating by speeding up production of a chemical messenger in the brain called GABA, or gamma-amino butyric acid. When combined with another molecule GABA stimulates us to eat. However genes do not always predict future health. Genes and behavior may both be needed for a person to be overweight. In some cases multiple genes may increase one’s susceptibility for obesity and require outside factors; such as abundant food supply or little physical activity.
2. Snacks can make people obese and high-wired :
A poor diet—to high-calorie foods that are widely available, low in cost, heavily promoted, and good tasting. These ingredients produce a predictable, understandable, and inevitable consequence—an epidemic of diet-related diseases. While such foods are fast and convenient they also tend to be high in fat, sugar, and calories. Choosing many foods from these areas may contribute to an excessive calorie intake. Some foods are marketed as healthy, low fat, or fat-free, but may contain more calories than the fat containing food they are designed to replace. It is important to read food labels for nutritional information and to eat in moderation.
People who eat breakfast are significantly less likely to be obese and diabetic than those who usually don’t, reported by the American Heart Association at their 43rd Annual Conference on Cardiovascular Disease Epidemiology and Prevention. In their study, researchers found that obesity and insulin resistance syndrome rates were 35 percent to 50 percent lower among people who ate breakfast every day compared to those who frequently skipped it.
3. Fast food infiltration in our culture :
You can drive down the road in many communities and pass five or six service stations, fast food restaurants, and convenience stores in less than a mile. There are fast food restaurants inside some schools. Malls have food courts. Fast foods are showing up on airline flights and in airports. It’s basically everywhere. The food industry spends $30 Billion annually to convince people to eat their products. The problem, is that the industry makes its most if its money through selling highly processed foods.
8. Diseases and Drugs :
Some illnesses may lead to obesity or weight gain. These may include Cushing’s disease, hypothyroidism, depression and polycystic ovary syndrome. Drugs such as steroids and some antidepressants may also cause weight gain. Also, drugs such as steroids and some antidepressants may cause weight gain. A doctor is the best source to tell you whether illnesses, medications, or psychological factors are contributing to weight gain or making weight loss hard.
