A new review examined both psychological and physiological effects of loosening dietary rules. The paper, published in Nutrition Reviews, notes that planned higher-calorie meals can support motivation, while unplanned or binge-like episodes may lead to guilt, shame and unhealthy patterns.
Physically, a single large meal produces only a small, temporary metabolic increase that is tiny compared with the extra calories. Mentally, framing a meal as "cheating" can make people feel their diet has failed, and that feeling can lead to more overeating and a binge-restrict cycle.
The review included only a small number of studies, so the authors call for more research. They advise planned flexibility in eating and point out that meals are also social and cultural events.
