How Obese adults African American between the ages of 25-35 can loss weight.

Can you please help me to formulate a PICO question for my research paper. My topic is uploaded below but my instructor want me to be specific and it should also be in a nursing domain. Instead of weight loss pills it should be something a nurse can do because nurses can not prescribe medication. My population should be specific which I want to use African Americans with a specified age group. I want something that a nurse can do different apart from exercise to make a patient lose weight in the form of PICO question. Just look at the topic and help me fix it. Replace the weight loss pills with something in a nursing domain. Help me fix the question for my instructor to approve then we go ahead and write.
