In the field of diet and nutrition, there is a fundamental debate between calorie counters and proponents of specific diets, whether low-fat, low-carbohydrate, or buy-my-line-of-expensive-formulated-products. The issue is less whether any such diet works in general (though some of them are actually unhealthy) than whether more than a few individuals can follow such a regimen over the long term.
在饮食和营养领域有一个根本性的争论，即卡路里斗士和具体饮食方法之争——不管是低热量派、低碳水化合物派还是“订购我的昂贵配方餐”派。问题与其说在于一般而言这样的饮食是否有效（尽管其中一些其实是不健康的），不如说在于是否能有较多的个人长期坚持这一套。
