The health consequences of *yo-yo dieting* include metabolic disruption and psychological effects. Repeated cycles of losing and regaining weight can lead to a decreased resting metabolic rate and the potential for increased fat retention. This cycle places unnecessary stress on both the body and mind, potentially fostering disordered eating behaviors. Additionally, fluctuations in weight can result in physical fatigue, loss of muscle mass, and increased risk for chronic diseases related to obesity. Maintaining consistent, healthier eating habits is vital for long-term health and weight management.
