Hi and welcome! I have never done lipotrim so can't really comment sorry. There is a forum for each diet though so maybe have a look around all of those and ask a few questions and I am sure you can find out what will be the right diet for you.
I have tried weight watchers, atkins and calorie controlled and I am now doing slimming world which I think is definitely for me but everyone is different so have a look around and good luck!!
