How do you get yourself into that frame of mind to be successful? I don't think it matters what "diet" you are doing, I think you really need to be in the right frame of mind to lose weight.
I have been on many diets in my time and lost a little weight but it never lasted and I never lost enough to even notice a difference.
The one time I did manage to lose alot of weight was years ago, I done WW. I was so strict with myself and almost became obsessed but It was the only way it worked for me, my frame of mind was almost like disgust, certain foods disgusted me and so did my weight. I hope I can get that back lol.
What is yours like?
