Yes, it’s true—the quiz starts out with instructions to think back to a time in your life when your eating was at its worst, and to answer the questions as if you were living back then. There is a scientific reason for this. A large body of evidence shows that once your brain has been wired for any behavioral or emotional response pattern, including food addiction, those fiber tracts in the brain never go away; they will always be there, waiting to be activated again. You can come to behave and feel very differently about food over time, and enjoy freedom and neutrality around your eating, but the underlying susceptibility is always still there.
In other words, if you once were a 9 on the Susceptibility Scale, you’ll always be a 9, because you’ll always need to be more aware and vigilant around food than someone who, at their worst, was a 5.
You can take the quiz a second time from the perspective of how you respond to food today, but it would be unwise to use that score to guide the construction of your Bright Line Eating plan.
Remember, out in the general population, fewer than 1% of people who have a lot of weight to lose will succeed at losing all their excess weight and keeping it off long-term. A big reason for this is that once a healthy pattern of eating is established, people get complacent and forget their underlying susceptibility. Long-term weight loss, and all the happiness, health, and freedom that goes with it, require keeping your Susceptibility Score firmly in mind and molding your eating habits accordingly.
