Obesity is not a disease. It is the cause of diesease. Diabetes, heart disease, and DEATH! If it runs in the family, then... well... That family is not setting very good examples of health for their decendants.
Obesity is a choice. You can choose to obesity. My aunt weighed almost 350 pounds... and she is 5'5! She was in danger of dying... She's only just turned 30!! But she stood up and said NO... She chose to shape her own destiny. Through diet change and exercise, she has dropped her weight to 170!! WOW - She's lost 180 pounds. And she is losing more and more everyday.
