If I may add my 2 cents,
I believe self sabatoge is well... just that.
Something you do to yourself when you are just not ready to lose the weight. It may be The fact that, oh if i lose all this weight I will have to buy all new clothes etc... My biggest on was eww!! If I lose all that weight me skin will droop and be gross. (((HELLO))) It gross to have all this fat too.
I think once you have really made up your mind to do it. However it may be. No one can hold you back. I have not stuck to one "diet" for more that 2 weeks my whole adult life. I am on my 2nd month of this WOE. And let me tell ya not one person could make me stop now. Yes it was discouraging at first cause i lost soooooo slooooowww!!! but now 3 lbs in less than 2 weeks. Well it's wont win me any race, but it's better than the first month.
Moral to the story If you are TRULY ready to lose weight no one can sabatoge you, including yourself.
Toodles,
