What are the common health consequences and the Major risks of overweight and obesity?
According to the World Health Organization (WHO), "the fundamental cause of obesity and overweight is an energy imbalance between calories consumed and those expended."
The obesity epidemic invading the world is due, according to the same organization,to both " Changes in dietary in the world" (greater consumption of high-calorie foods rich in fat and sugar ) and lack of physical exercise.
Overweight & Obesity: What is the difference?
According to the The organization Overweight and obesity are defined as abnormal or excessive fat accumulation that may impair health.Body mass index (BMI) is a simple index of weight-for-height that is commonly used to classify overweight and obesity in adults. It is defined as a person's weight in kilograms divided by the square of his height in meters (kg/m2).
The WHO definition is:
a BMI greater than or equal to 25 is overweight
a BMI greater than or equal to 30 is obesity.
BMI provides the most useful population-level measure of overweight and obesity as it is the same for both sexes and for all ages of adults. However, it should be considered a rough guide because it may not correspond to the same degree of fatness in different individuals.
So What are The Negative Effects of overweight & Obesity on Your Health and Life?
Raised BMI is a major risk factor for noncommunicable diseases such as:-Cancers: A postmenopausal woman doubles her risk for breast cancer if she gained as little as 20 pounds before menopause. Almost half of all breast cancer cases occur among obese women. The endometrial cancer risk among postmenopausal women also increases with weight gain, and being overweight increases the chances by one and a half times that a woman will DIE from her cancer.
-Diabetes: Nearly 80 percent of people with type 2 diabetes are obese. This disease is particularly linked to weight gain after the age of 18. Even overweight children are getting the kind of diabetes that used to be associated only with overweight adults.
Losing as little as 10 pounds can reduce your risk by 30 percent. And for those who already have type 2 diabetes, reducing body weight by as little as 5 percent can significantly improve blood glucose levels. Weight loss may also improve insulin sensitivity, which means that cells respond more efficiently to insulin.
-Gallbladder disease: The incidence of gallstones soars as a person's body weight increases. A middle-aged woman who is more than 40 percent over her ideal body weight has a 33 percent greater chance of having gallstones than a lean woman of the same age.
-cardiovascular diseases: (mainly heart disease and stroke), which were the leading cause of death in 2012;Nearly 70 percent of the diagnosed cases of heart disease are related to obesity. A weight gain of 20 pounds doubles your risk of heart disease. Fortunately, though, reducing your weight by only 5 to 10 percent increases your HDL levels while reducing LDL and triglyceride levels.
-Hypertension (high blood pressure): Being obese more than doubles your chances of developing high blood pressure. Statistics show that approximately 70 percent of obese American men and women have high blood pressure.
-Respiratory problems: Respiratory complications, such as sleep apnea, are linked to obesity. Losing 10 to 15 percent of body weight can cure apnea.
-Osteoarthritis: Being overweight or obese increases your risk for getting this painful disease, causing the bone and cartilage in your joints to degenerate. One study reported that a weight gain of 9 to 13 pounds increased the pain in the knees of arthritis sufferers. On the flip side, losing the same amount decreases the odds of getting arthritis by 50 percent.
-Psychological and social effects: Overweight and obese folks often face discrimination at work and in social settings. Feelings of rejection, shame, or depression aren't uncommon. Also, American society equates thinness with attractiveness.
Childhood obesity is associated with a higher chance of obesity, premature death and disability in adulthood. But in addition to increased future risks, obese children experience breathing difficulties, increased risk of fractures, hypertension, early markers of cardiovascular disease, insulin resistance and psychological effects.
-Several cities in the United States, where obesity rages, have recently taken Action:
Los Angeles banned the opening of new fast food in poor neighborhoods, and New York has banned the use of trans fats in restaurants. New York authorities also forced fast food - 10% of restaurants in the city - to display the calories contained in the Junk they serve.
-It's not a secret that the key to avoid such serious health complications is to adapt a healthy life style relying on a complete weight loss Program that combines healthy balanced diets,suitable exercising and eventually supplemented with a powerful and natural fat burner to speed up the weight loss process.
