"I deserve it"

Hi, I would like some help with what it would be the best approach with a client who insists on the answer of “I deserve it” when we are talking about her evening food behaviors of reaching for high carb foods and alcohol every night.
We have started a conversation about what else she could be looking for when she reaches for these foods (mainly during the evenings), but what I feel is that she “wants to be healthier but not that much…” And she insists that she deserves it because this makes her remind her childhood with her family, a dinner table with lots of foods, and happiness.
My point is that I feel she knows that this habit doesn’t serve her but, unconsciously, she didn’t find yet a motivation capable to change her habits. She feels ok about being like that even she keeps saying that she would like to lose weight and get healthier.
Thank you.
