For much of my life I followed the commonly held belief that a low fat diet is both good for you and supports a healthy BMI. Regularly consumed 'foods' included diet coke, skim milk, egg white omlette's, low fat dressings, diet yoghurt, cheese, sugar free gum and more. If you are still consuming these less healthy (yes less healthy) staples listen up. Stop right now.  I guess you are wondering why?
