Which of the following is an example of a process goal?

A process goal is focused on the actions or behaviors one can control, which ultimately lead to achieving an outcome goal. In this context, controlling appetite reflects an intention to implement specific habits that directly influence eating behaviors, making it a clear example of a process goal.

This choice emphasizes the ongoing effort in managing one's behavior, which is essential when making lasting lifestyle changes. By focusing on appetite control, one can develop strategies to prevent overeating or make healthier food choices, establishing a foundation for achieving broader objectives like weight loss or improved health.

In contrast, the other options presented are examples of outcome goals which are quantifiable and result-oriented. Drinking a specific amount of water or reducing calorie intake are specific targets that reflect desired outcomes but do not encapsulate the behaviors necessary to reach those goals in a way that encourages a process-oriented mindset. Similarly, losing a certain amount of weight is a clear outcome and does not address the behaviors required to bring about this change.
