What health behavior strongly reduces risk of chronic disease when performed regularly?

• A. Smoking cessation only
• B. Regular physical activity and healthy eating
• C. Avoiding all fats
• D. Reducing sleep to 5 hours

Answer: (B)

Regular physical activity paired with healthy eating is a powerful, consistent way to lower chronic disease risk. Exercise improves weight management, lowers blood pressure, enhances insulin sensitivity, and boosts cardiovascular fitness. A diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats supports heart health, reduces inflammation, and helps prevent diabetes and certain cancers. When these two behaviors are practiced together, they reinforce each other—being active aids in maintaining a healthy weight and metabolic health, while a nutritious diet provides the fuel and nutrients needed for performance and recovery. This combination typically produces greater risk reduction than focusing on a single change.

Stopping smoking is extremely important, but the option framed as “smoking cessation only” implies you’re not addressing activity and diet, which also matter. Avoiding all fats is not necessary or healthy, since some fats are essential. Reducing sleep to 5 hours is harmful and increases, not decreases, chronic disease risk.
