Okay..I eat quite alot of unhealthy food - like food high in sugar, fat and salt (pizza, fried chicken, etc), and I get little or no exercise, plus I drink Coca-Cola like everyday. I am not overweight because the medicine I take for ADHD (concerta) reduces my appetite. Oh, and I m 17. Am I putting myself at risk of heart disease? There s no family history of heart problems.
