The term "healthy weight" refers to an individual's body mass index (BMI) that falls within a healthy range according to their height and build. It means having an appropriate amount of body fat, muscle, and bone for one's overall health and well-being. A person with a healthy weight is less likely to develop chronic diseases such as heart disease, diabetes, and certain types of cancer. Maintaining a healthy weight through proper nutrition, exercise, and lifestyle habits can help prevent obesity and related health problems.
