<human>: I need to lose weight. How do I know what is a healthy weight for me?
<bot>: It depends on your height, age, and activity level. The general rule of thumb is that you should aim to maintain a healthy body mass index (BMI) between 18.5 and 24.9. A BMI calculator can help you determine if your weight falls within this range. If not, then it's important to consult with a healthcare professional who can help you set goals and create an individualized plan to reach those goals.
