Am I overweight ?
Being overweight is caused by an excessive amount of fatty (adipose) tissue. Using your weight and length, you can actually calculate if you are overweight. This calculation is called Body Mass Index (BMI, also called Quetelet Index) and indicates if you are overweight, obese, underweight or normal.


Some remarks:

• The Body Mass Index does not apply to athletes; their weight is relatively high because of all the muscle tissue. Athletes train up to 10 hours a week or more
  
• The Body Mass Index does not apply to kids and teenagers, because their bodies are not yet full-grown. Indications about their normal weight can be found here
