Calculating ideal weight using body mass index (BMI) involves determining the relationship between height and weight to assess body fat. For instance, a person who is 5’9″ tall and weighs 150 pounds has a BMI of 22.7, indicating a healthy weight range.
Understanding BMI is essential for maintaining a healthy weight, reducing the risks of obesity-related illnesses, and making informed lifestyle choices. Its development in the 19th century by Adolphe Quetelet laid the foundation for assessing body composition and promoting healthy weight management practices.
