The term for eating patterns that cycle between strict dieting and binge eating is "yo-yo dieting" or "binge eating disorder." This behavior often involves alternating between periods of extreme caloric restriction and episodes of excessive food consumption. It can lead to significant emotional distress and disrupt physical health, as the body struggles to maintain equilibrium. Individuals engaging in this cycle may experience feelings of guilt or shame after bingeing, which can further perpetuate the cycle. Understanding and addressing the psychological underpinnings of these patterns is essential for developing healthier, sustainable eating behaviors and fostering a positive relationship with food.
