Which of the following is a lifestyle risk factor?

• A. Overweight
• B. Balanced diet
• C. Regular exercise
• D. Heart disease

Answer: (A)

Lifestyle risk factors are modifiable behaviors in daily life that raise the likelihood of disease. Overweight fits this because it results from long-term energy imbalance driven by eating patterns, portion sizes, and physical activity levels. Excess body weight increases the risk of cardiovascular disease, type 2 diabetes, and hypertension, and it can be reduced or managed through diet and activity changes, which is why it’s considered a lifestyle-related risk factor. In contrast, a balanced diet and regular exercise are protective behaviors that help lower risk, not factors that increase it. Heart disease is a condition that can develop from risk factors, rather than a lifestyle factor itself.
