The grapefruit diet where you ate nothing but grapefruit, boiled eggs and cooked spinach. My mother, of all people, put me on this diet when I was in high school. Any wonder why I have problems relating to my mom? To this day I totally despise grapefruit and only recently have been able to eat boiled eggs. Cooked spinach I won't touch with a 10 foot pole but I love it raw in salads. I also did NutriSystem - ate a lot of cardboard food and wasted a lot of money. As soon as I tried to eat regular food again I gained back all of the weight I lost and then some.
