BMI = Weight in kgs
(Height in metres)*2

  • Emotional/Psychological Illness- Extremely overweight persons face constant challenges to their emotions: repeated failure with dieting, disapproval from family and friends, and remarks from strangers. They often experience discrimination at work. Stereotypes of obese people – such as that they are lazy – may result in lower self esteem and poor body image.
