Final answer:
The client is most likely in the Contemplation stage of change, where she acknowledges her eating habits as a problem but hasn't committed to making changes.
Step-by-step explanation:
The client described in this scenario is likely in the Contemplation stage of change. In the Contemplation stage, individuals acknowledge that they have a problem but may not be ready or certain of wanting to make a change. The 35-year old woman's recognition of her poor eating habits, coupled with an ambivalent attitude towards changing her nutritional choices, indicates that she is aware of her issues with food but is not yet committed to taking action to address them. Her statement, "I have no idea. I just can't change my eating habits," suggests that she is considering change but is also experiencing barriers to making those changes, such as finding most vegetables repulsive and fruit sticky. In contrast, the Preparation stage would involve some degree of readiness to start making changes, the Action stage would involve active modification of behavior, and the Maintenance stage would involve sustained change over time with efforts to prevent relapse.
