I was able to lose that amount in 1 month just doing a diet i've thought of. I know it's not the best but given the way i eat nowadays it didn't really matter to me.
For breakfast i had a slimfast shake, lunch i had a boost protein drink and dinner i have an all protein dinner (meats! doesn't matter if it's something you cook or buy at a chinese place... yumm hehehe). If you have lunch just substitute dinner for the slimfast or boost ... e.g. jumble them up according to your taste.
Given i previously didn't eat breakfast and lunch, and dinner was my only real meal it wasn't hard for me to do this. Substituting most of my intake with protein really helped me a lot, i felt i had more energy and just wanted to keep up and going.
Since i lost the 30lbs January of this year i stopped this particular diet and have been going back to my routine of just eating whatever and whenever i feel like it (your mileage may vary) and i've only gained 5lbs. of it... and that was actually just over this thanksgiving weekend hehehehe
