Overweight is generally defined as having more body fat than is optimally healthy.

Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health, leading to reduced life expectancy and/or increased health problems.

Body Mass Index (BMI) is a simple index of weight for height that is commonly used to classify overweight and obesity in adults. To determine your BMI, divide your weight in kilograms by the square of your height in meters.

Based on Asia-Pacific BMI standards, it defines people as overweight (pre-obese) when their BMI is between 23 kg/m2 and 24.9 kg/m2, and obese when it is 25 kg/m2 or greater.


Health Implications

Excessive body weight is associated with various diseases, particularly cardiovascular diseases, diabetes mellitus type 2, obstructive sleep apnea, certain types of cancer, osteoarthritis and asthma. As a result, obesity has been found to reduce life expectancy.
