Hi Louise.
I would go all out 100% until goal, with no stoppages. I would stay focused and determined throughout to get the weight off once and for all.
LT works amazingly well if you have a big amount of weight to lose. It works even better is you stick to the plan 100%
I have been on it 8 months straight, 100% and have lost 12 stone. It has changed my life beyond recognition. You too can achieve your goal if you want it badly enough, and stick to the rules. LT works more effectively is used how it was designed to be used.
What height are you Louise?
