Sugar addiction and protocol use

Hi Coach
I am a Health Coach and I use Brooke’s overeating program with my clients. I have a new client that is “addicted” to sugar. I feel like I can’t just tell her to start by making a commitment to not eating sugar on her protocol. How should I approach this with her? I will use the urge jar process but I’m not sure that will be enough. All my other clients don’t eat much sugar anyway so the process of going sugar free wasn’t an issue for them. Your guidance would be appreciated. Thanks so much in advance.
