I might be wrong but I thought Lipotrim was only available to those who needed it because they were 3 stone or more overweight -or- had a BMI over 30. Without trying to sound mean (seriously, I'm not trying to be horrid) I wouldn't have thought that LT would be the correct diet for you as you only need to lose a stone and are already in the healthy BMI range.
If, however, you have been advised to take on LT by a medical professional then I would say that your weight loss will not be as great as most of the people here on the forum as you do not need to lose as much - possibly a couple of lbs a week?
Obviously I don't know everything - don't even know a lot so hopefully someone will be along who can answer this better but that's my two cents anyhow.
Aside from all that, welcome to the forum. x
