Dieting is a common method for weight loss, maintenance, and prevention of weight gain, but the harmful outcomes of dieting are understudied. Dieting is typically advised for obese patients for the sake of their health, though this does not account for the many complicated factors surrounding obesity. We conducted a search through the PubMed database on obesity, dieting, and eating disorders and did not limit the study by population or year. We found studies showing that although dieting may cause short-term weight loss, it is associated with weight gain in the long-term. We also found studies assessing the negative psychological and physical outcomes of dieting. Though there are many studies that emphasize the negative psychological impact of dieting, few studies have explored how dieting may contribute to the development of eating disorders in the obese. Studies on the physical impact of dieting were less conclusive but warrant further study. While it is difficult to draw any substantial conclusions from the data, our results showed that dieting may carry more risks than benefits as a means to lose weight.
节食是一种常见的减肥、维持体重和防止体重增加的方法,但节食的有害后果却未得到充分研究。出于健康考虑,通常建议肥胖患者节食,不过这并未考虑到围绕肥胖的诸多复杂因素。我们通过PubMed数据库搜索了有关肥胖、节食和饮食失调的内容,且未对研究的人群或年份加以限制。我们发现一些研究表明,尽管节食可能导致短期体重减轻,但从长期来看,它与体重增加有关。我们还发现了评估节食负面心理和生理后果的研究。虽然有许多研究强调节食对心理的负面影响,但很少有研究探讨节食如何可能导致肥胖者出现饮食失调。关于节食对身体影响的研究结论不太确凿,但值得进一步研究。虽然很难从这些数据中得出任何实质性结论,但我们的结果表明,作为一种减肥手段,节食可能带来的风险大于益处。
