Obesity is a complex disorder involving too much body fat, obesity is not just a question of cosmetics, it increases your risk of disease and health issues like heart disease, diabetes, and high blood pressure.
Obesity is a medical condition that occurs when an individual carries excess weight or body fat that may affect their health, usually a doctor will suggest an individual has obesity if they have a high index of body mass.
Many factors influence the genes of body weight, although the effect is small and heredity is not destiny, influences of prenatal and early life, poor diets, too much television watching, too little physical activity and sleep, and our environment of food and physical activity.
- A number of cancers have obesity as a risk factor.
- Obesity means excess fat on the body. It is obese for adults 35 years of age and older with BMI over 30.
- Even a modest weight loss of 5%-10% of the initial weight and the long-term maintenance of that weight loss can bring significant health benefits by lowering blood pressure and reducing diabetes and heart disease risks.
- It is a chronic medical condition that can lead to diabetes, high blood pressure, heart disease, gallstones, and other chronic diseases.
- If the doctor works with a team of professionals including dietitians, psychologists, and exercise professionals, the chances of long-term successful weight loss are enhanced.
- Obesity is hard to treat, and it has a high rate of relapse. Within five years, most people who lose weight recover their weight.
- Treatment goal should be achieving and maintaining a “healthier weight,” not necessarily an ideal weight.
What is obesity?
Obesity definition varies depending on what you read, overweight and obesity generally indicate a weight that is greater than healthy.
Obesity is a chronic condition which is defined by excess body fat, to store energy, heat insulation, shock absorption and other functions, a certain amount of body fat is needed.
The Body Mass Index (BMI) is the weight of a person in kilograms (kg) divided into meters (m) squared by their height (more information can be found later in the article). Because BMI describes body weight relative to height, adults have a strong correlation with total body fat content.
An adult with a 25-29.9 BMI is overweight, and an adult with a BMI in excess of 30 is obese. An individual with an 18.5-24.9 BMI has a normal weight. If your BMI is over 40, a person is morbidly obese (extreme obesity).
What is the body mass index (BMI)?
For many doctors and researchers studying obesity, the body mass index (BMI) is now the measure of choice.
The BMI uses a mathematical formula which represents both the weight and height of a person.
The BMI is the weight of a person divided by height in square meters (BMI = kg / m2) in kilograms. Divide the weight in pounds by the height in inches squared and multiply the result by 703 in order to calculate the BMI using pounds.
Understanding what “healthy weight” means is important. Healthy weight is defined as an index of body mass (BMI) equal to or greater than 19 years of age and less than 25 years of age among all people. obesity is generally defined as an index of body mass (BMI) equal to or greater than 30 pounds of excess weight.
The World Health Organisation, using the BMI to define overweight and obesity, uses a classification system.
- A BMI of 25 to 29.9 is defined as a “pre-obese.”
- A BMI of 30 to 34.99 is defined as “obese class I.”
- A BMI of 35 to 39.99 is defined as “obese class II.”
- A BMI of or greater than 40.00 is defined as “obese class III.”
Math and metric conversions have already been done in the table below. find the appropriate height in the left column to use the table, move to the given weight through the row, for that height and weight, the number at the top of the column is the BMI.
Below is a table identifying the BMI and waist size associated disease risk.
If your body mass index (BMI) is 30 or higher, obesity is diagnosed, your body mass index is calculated by dividing your weight by meter (m) square in kilograms (kg).
BMI provides a reasonable estimate of body fat for most individuals, BMI does not directly measure body fat, however, so some people, such as muscular athletes, may have an BMI in the category of obese even though they do not have excess body fat. Ask your doctor if there is an issue with your BMI.
You can take steps to prevent unhealthy weight gain and related health problems, whether you are at risk of becoming obese, currently overweight or at a healthy weight.
Not surprisingly, weight gain prevention steps are the same as weight loss steps: daily exercise, a healthy diet, and a long-term commitment to watching what you eat and drink.
