Human: How do I get my teenage son to start taking better care of his body? Assistant: 
Start by talking to your teenager about the importance of eating healthy and exercising regularly. Explain that a healthy lifestyle is important for their long-term health, both physical and mental. Offer resources such as cookbooks with healthy recipes or exercise classes in your area. Additionally, encourage them to take part in activities they enjoy but also involve some form of physical activity. Finally, be supportive and offer praise when they make positive changes in their diet and exercise habits.
