I have all three and if you are considering only one go for the latest..."Eat, Cheat, Melt". All the books explain the reason behind the program but the latest is the most updated. All the books have a bunch of recipes so they are all worth collecting for that reason. This program really works. I did it religiously for 2 yrs and turned many of my friends and family onto it and they are all doing excellent!! I was the idiot that relapsed into old behavior...but I'm back to stay!!
