Guidelines for maintaining a healthy body weight involve balancing calorie Intake with energy expenditure. Regular physical activity, including both aerobic and strength training exercises, is crucial. Eating a well-rounded diet rich in whole foods, such as fruits, vegetables, whole grains, and lean proteins, promotes satiety and nutrient intake. Monitoring portion sizes and reducing intake of added sugars and unhealthy fats can also help. Setting realistic goals and maintaining consistency are vital for long-term success.
