　　Sodium¹ is lost until the body can balance itself out, and temporary fluid weight loss may occur. 在身体能够补充之前，我们流失了钠元素，而且还会出现体液流失造成的暂时体重下降。

　　With other high-protein diets, you might lose weight at first since by restricting your food choices, 使用其他高蛋白的饮食法时，也许早期由于控制了食物选择，你的体重会有所下降，

　　you are dropping your overall calorie intake². 你在减少你的整体卡路里摄入。

　　But your body then lowers its metabolic³ rate to adjust to the shift, 但是稍后你的身体会降低代谢速率以适应这种转变，

　　lessening⁴ the diet's effect over time and resulting in a quick reversal if the diet is abandoned. 节食的效果也会就此渐渐减轻，并且放弃这种饮食法后会导致快速反弹。

　　So while these diets may be alluring⁵ early on, they don't guarantee long-term benefits for your health and weight. 所以，虽然这些饮食法早期也许非常诱人，但它们不能保证对你的健康和体重有长期的好处。

　　A few simple guidelines, though, can help differentiate⁶ between a diet 不过，有一些简单的准则可以帮你将有利于

　　that is beneficial in maintaining long-term health, and one that only offers temporary weight changes. 保持长期健康的饮食法和只能带来暂时体重变化的区别开来。

　　Here's the first tip-off: if a diet focuses on intensely cutting back calories or on cutting out entire food groups, 第一条提示：如果一个饮食法密切关注减少卡路里或者排除整个食物群，

　　like fat, sugar, or carbohydrates⁷, chances are it's a fad⁸ diet. 像脂肪、糖或碳水化合物，那它很有可能就是一个流行饮食法而已。

　　And another red flag is ritual, 另一个危险信号是惯例，

　　when the diet in question instructs you to only eat specific foods, prescribed combinations, 也就是存疑的这个饮食法指导你只食用特定的食物，规定的搭配，

　　or to opt⁹ for particular food substitutes, like drinks, bars, or powders. 或者选择特定的食物替代品，比如饮品、能量棒或粉末。

　　The truth is shedding pounds in the long run simply doesn't have a quick-fix solution. 真相是，长期减重并没有捷径可走。

　　Not all diet crazes tout¹⁰ weight loss. 并不是所有的饮食法都标榜减重。

　　What about claims of super foods, cleanses¹¹, and other body-boosting solutions? 那些号称超级食物、身体净化剂和其他强身健体的方案怎么样呢？
