Final answer:
John with a BMI of 26 is considered overweight according to CDC guidelines.
Step-by-step explanation:
John weighs 242 pounds and has a body mass index (BMI) of 26; according to the Centers for Disease Control and Prevention (CDC), an adult with a BMI between 25 and 29.9 is considered overweight. Therefore, John is considered overweight. BMI is an important measure used to categorize weight status and can indicate a higher risk of developing health conditions when elevated above the normal range. However, it is important to note that BMI is a general guide and not a definitive indicator of individual health as it does not account for muscle mass, bone density, overall body composition, and ethnic disparities in body fat distribution.
