Effective strategies for maintaining a healthy weight include adopting a balanced diet, engaging in regular exercise, setting realistic goals, and practicing portion control. A balanced diet incorporates a variety of nutrient-rich foods such as fruits, vegetables, whole grains, and lean proteins. Regular physical activity, including aerobic and strength training, helps burn calories and builds muscle. Setting achievable goals helps maintain motivation and prevent disappointment. Monitoring food intake and practicing mindful eating can further assist in avoiding overeating and maintaining desired weight levels over time.
