A 55-year-old male has been visiting the clinic for routine health checks. During the assessment, the nurse notes a family history of cardiovascular disease, a sedentary lifestyle, and a diet high in saturated fats. The nurse is educating the patient about his risk factors for developing heart disease. Given that the leading preventable cause of cardiovascular disease is linked to lifestyle choices, the nurse emphasizes the importance of achieving a healthy body weight. The optimal Body Mass Index (BMI) range that should be maintained to minimize these risks is between ____ and ____.

Convert this BMI range by finding the corresponding weight for a person who is 175 cm (5 feet 9 inches) tall. Use the BMI formula: BMI = weight (kg) / (height (m)^2), where the height must be converted to meters (1 cm = 0.01 m).
