Do you know what a healthy weight is?
In our society now, obesity has become one of the most dangerous health problems. The nature of life now reduce the human effort, and people prefer comfort using the latest technology. For example, many persons use a car for short distances instead of walking. The ideal weight is the weight that is appropriate for your body and your height. It is determined by measuring BMI and waist. Obesity is determined by calculating the percentage of body fat and weight, according to the National heart, lung and blood Institute (NHLBI). A large percentage of body fat, regardless of the weight- is unhealthy. Where it is possible to have the weight of a normal person or have a decrease in weight, but is suffering from an unhealthy amount of body fat. The increase in weight does not necessarily mean an increase in the amount of fat in the body. For example, people who have muscle sports have weight gain but this extra weight is muscle weight, not fat.
According to guidelines from the National heart, lung and blood Institute (NHLBI) obesity is diagnosed by three criteria: • BMI (Body Mass Index-BMI) • Waist circumference • Risk factors for diseases associated with obesity, including high blood pressure and high cholesterol (low density lipoprotein) and high triglycerides, and high blood sugar and tobacco.
BMI (Body Mass Index-BMI) The first measure of obesity is the body mass index, which is measured by dividing the weight in kilograms over height in meters. The information you provide us by BMI are as follows:
• Body mass index of 18.4 or less: low weight. You can check with your doctor to make sure there is not any disease can be the cause of weight loss.
• Body mass index of 18.5 to 24.9: normal weight. Typical weight is the recommended weight for your height class, but that doesn't mean you're safe from diseases, must maintain exercise regularly and eat healthy.
• Body mass index of 25 to 29.9: overweight. That weight gain can be or not be unhealthy depending on waist circumference and the presence of risk factors or other health problems.
• Body mass index of 30 or more: obesity. You may need to lose weight by following a healthy diet and exercise daily health habits which include sport even maintain the health of your body and protect yourself from the disease.
For people who are obese or overweight, have the factors increase the likelihood of disease, the guidelines of the National heart, lung and blood Institute (NHLBI) recommends the need to lose weight. Although the BMI is a reliable indicator of body fat, but there are some limits. So that may be an overstatement of body fat in athletes and others who have high muscle mass. It also may reduce body fat in older persons and others who have lost muscle mass.
Fat in the abdomen or waist circumference (Abdominal Fat, Waist Circumference) The second way to determine if you suffer from obesity or weight gain is the measurement of abdominal fat. Can predict the risk of obesity. Waist circumference is determined by placing the tape measure around your waist. Waist circumference is a good indicator of fat in the abdomen. Increase the risk of obesity-related diseases with increased waist circumference measurement of more than 40 inches (102 cm) for men and more than 35 inches (89 cm) for women.
Measuring waist circumference You must use the measurement of abdominal fat along with measurement of body mass index to assess your risk. For example: If you have overweight (BMI of 25 to 29.9), but did not have an increase in the waist circumference and risk factors is less than 2,so, you only need to prevent any further increase in weight, you do not need to lose weight. If you suffer from overweight, and have risk factors for obesity-related diseases, you should lose weight. If you suffer from obesity, you should lose weight even if you have no other risk factors.
Alternative means of measurement Anthropometry: is a third method to determine if you suffer from obesity. Measuring the thickness of the skin or the so-called (Anthropometry), so in this way the skin thickness measurement of several regions, such as the triceps muscle, and on the shoulder and hips. Results determine whether your weight is muscle or fat. However, usually prefer to use BMI as it reflects a more accurate representation of the total body fat compared with height and weight.
