Hey what do you know, I have just calculated my BMI (body mass index) and am no longer officially classified as obese! I am now just overweight.
To calculate your BMI you take your weight in kilos then divide this by your height in metric squared.
Grade of obesity BMI Description
0 .................... 20-24 Desirable weight
1 .................... 25-29 Overweight
2 .................... 30-39 Obese
3 .................... 40+ Morbidly obese
