What is the definition of fat or thin?
The World Health Organisation (WHO) defines a healthy adult BMI as being between 18.5 and 25. A BMI less than 18.5 indicates underweight (possibly caused by disease, malnutrition or eating disorders such as anorexia nervosa) and a BMI over 25 as overweight (possibly caused by poor diet choices or lack of exercise).
Guidlines for BMI results
normal: 18.5 to 24.9
underweight: less than 18.5
severe underweight:less than 16
overweight: greater than 25
obese: greater than 30
Those whose BMI is too high (that is, they are too heavy for their height, gender and age) may be at risk of the diseases associated with overweight and obesity (such as heart disease, joint diseases, diabetes and cancer).
But it happens to all of us: as the years go by, the scales slide up.
