It seems wherever we go or whatever we see and hear there is always something about obesity. We all aware of weight gain is bad for you, but what are surrounding us are supersized meals and neighbourhood not designed for walking, is there any way to win this battle against obesity?
Luckily, the answer is yes. And the strategy begins with knowing your enemy.
What Is Obesity?
Obesity rates have been increasing steadily in last 25 years. According to a recent survey results conducted by National Health and Nutrition Examination, 35 % of women and 33 % of men were found obese. Moreover, among adolescents and children, 16 % of them were obese.
In simple words, obesity is carrying excess body fat enough to put you at risk for various health problems such as hypertension, diabetes, cardiovascular disease, pulmonary disease, stroke, reproductive disorders, cancer, osteoarthritis, and so on. Dr Jennifer Nasser, assistant professor in the department of biology at Drexel University in Philadelphia claims ìTo be brief, obesity can impact on all main body organ systems.î
Obesity is determined by your body mass index. It is figured out by using your height and weight. If you are adult, figure of 25 or more is considered to be overweight, and 30 and over falls in the obese category.
However, children and teens are not applicable for this formula. Rose Clifford, clinical dietician in the department of pharmacy services at the Washington Hospital Center in Washington, D.C. says ìThis format for teens and children are gender and age specific, as the body fat volume changes with age and boys are different from girls.î The Centers for Disease Control and Prevention provide an appropriate BMI calculator, Child and Teen BMI Calculator for people under the age of 20.
What Causes Obesity?
There are various of factors causing the present obesity epidemic. Caroline M. Apovian, associate professor of medicine and pediatrics at the Boston University School of Medicine and director of the Center for Nutrition and Weight Management at the Boston Medical Center says “Number of obese people are increasing because of the type of foods that are easily accessible and cheap. We are consuming 200 more calories daily now compared to 50 years ago.”
The society of advanced technology seems and looks good on the surface, our life is more convenient and easier. However, we are lazier as we can drive instead of walking, and we can just e-mail instead of walking to a colleagueís desk. Also, the environment can cause us to gain extra weight. Linda Bacon, associate nutritionist at the University of California, Davis, and author of ìHealth at Every Size: The Surprising Truth About Your Weight ìclaims ìWeight gain occurs by the interaction of environment and genes. Environmental circumstances are changing and some peopleís genes make them vulnerable to put on weight in the present environment.î Bacon claims that the environmental pollutions such as toxins, can cause changes in hormones which results in storing fat, and alter our eating habits. Some of the food commonly consumed in modern society, could interfere with our internal weight management mechanism, unlike the foods cone from nature.
What Are The Effects Of Obesity?
Not only causing health dangers, obesity can also put negative impact on economy and cause psychological problems such as depression and negative self esteem. However, the worst effect of all may be the discrimination which obese people have to cop in their daily life. Bacon claims ìDiscrimination against obese people is more common nowadays even more than racial discrimination or gender discrimination.î Even though obesity can be caused by the environment and genetics, still there are plenty of things you can do to battle and win. Keep yourself active by organizing regular exercise routine and stop spending too lazy time such as watching TV. And eat healthy and balanced meals. The portion size have to be appropriate, and include five servings or more of vegetables and fruits every day.
