Effective strategies for maintaining a healthy weight include adopting a balanced diet rich in whole foods, managing portion sizes, and engaging in regular physical activity. Tracking food intake and physical activity can provide valuable insights and accountability. Incorporating behavior change techniques like mindful eating helps in recognizing hunger cues, while setting realistic weight goals can foster motivation.
