One tip I can say is be focused and actually mean to diet. So many diets fail due to will power. With this diet the main motivation for me was seeing the weighing scales each week. In 4 weeks I have lost 17lbs (1stone 3) really can't complain about that.
Try to get in a frame of mind where you start being aware of what you are putting in your mouth and don't be worried to let your hair down now and then. during this four weeks I have had a Chinese takeaway with the the wife. but instead of having a usual fatty duck I went for a leaner prawn options and instead of Rice I actually picked a side salad, my wife was shocked hell I have shocked myself :d.
I do kinda have one rule to my diet ... if it's free I'm not gunna turn it down lol, so when my inlaws come round tomorrow night and take use out for a meal ...

I have seen so many ppl give advice on these forums and one sentence that spring up a lot is "Do what works for you"
