Bettina, I most certainly do think that flour and sugar are particularly addictive, but unlike the other programs you mention, I don’t encourage abstinence from them as the solution to your overeating. Same goes for weighing.
Consider that there are other addictions where abstaining as the solution isn’t viable: internet, shopping, exercise, sex.
With food, abstaining sets up an “all or none” relationship with food where you are either in rigid control or chaotically out of control. Much better to aim for something in between those extremes that you can live with because it’s flexible, as is life itself. That’s what I encourage you to aim for.
I won’t be getting down to the details of HOW to do this until Week 6, though, and that’s because I need to cover other material first. Then, I’ll pull it all together and explain how to be “imperfect” just a bit sometimes without falling completely off the wagon. A bit of sugar now and then won’t kill you, yes?
