Which factor can be controlled to assist in weight management?

The factor that can be controlled to assist in weight management is diet and exercise. This is because individuals have the ability to make conscious choices regarding their food intake and physical activity levels. By adopting a balanced diet and engaging in regular exercise, one can create a caloric deficit necessary for weight loss or maintain a healthy weight.

Diet plays a crucial role as it directly impacts the number of calories consumed each day, along with the types of nutrients that support overall health. Exercise contributes to weight management by increasing caloric expenditure and can improve metabolic health. Both components are essential in not just achieving weight goals but also in sustaining them over time.

In contrast, factors such as genetic predispositions, hormonal changes, and age-related metabolic decline are largely beyond an individual's control. While these factors influence weight and metabolism, they do not provide the same level of agency that diet and exercise do. Therefore, by focusing on what can be altered, individuals can effectively manage their weight.
