Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health.
In medical terms obesity is defined as a Body Mass Index of over 30kg/m2.
Obesity is no longer considered to be caused by a lack of self-control, and excessive calorie intake. The World Health Organization has classified obesity as a chronic progressive disease resulting from multiple environmental and genetic factors.

The body mass index (BMI) generally reflects the amount of excessive body fat an adult has, although there are certain exceptions, such as the BMI of an athlete, a body builder or pregnant woman. BMI does not necessarily take into account a person’s distribution of fat (abdominal vs. peripheral)
BMI takes into consideration your height and weight, and is calculated using following formula or the calculator below:
Weight in kilograms divided by Height in meters squared (BMI = kg/m2)
