Exercise, while not as effective as dietary restriction for promoting weight loss, is crucial for maintaining weight loss. Physical activity also helps preserve lean muscle mass during weight loss. To prevent weight gain and improve cardiovascular health, it’s recommended to engage in physical activity for at least 30 minutes, five to seven days a week. Although more exercise is needed for significant weight loss without dietary changes, combining a calorie-restricted diet with increased physical activity is ideal. The activity should start gradually and increase over time, with a focus on both aerobic and resistance training. Personal factors such as medical conditions, age, and exercise preferences should guide the exercise program.
