How often should individuals aim to engage in physical activity to maintain weight effectively?

Engaging in physical activity daily is crucial for maintaining weight effectively. Regular exercise contributes to creating a calorie deficit, which is essential for weight management, by burning calories and building muscle, which in turn increases metabolism. When individuals are active every day, they establish a routine that promotes consistent energy expenditure, thereby helping to prevent weight gain and support overall health.

Daily physical activity also has positive effects on mental well-being, improving mood and motivation, which can reinforce the habit of regular exercise. This consistent engagement helps individuals develop a lifestyle that supports their weight maintenance goals, making it easier to stick with healthy habits over the long term.

The other options do not encourage a frequency of physical activity that aligns with the research-backed recommendations for maintaining weight effectively. Exercising once a week, only when motivated, or every other week is generally insufficient for achieving the desired health outcomes and weight management success.
