科學家得出結論稱，並沒有證據支持「人們應該減少飲食中脂肪量」的言論。

來自哈佛大學的研究人員說：「衛生部門應該給出簡單的指導，專注於飲食量和未加工食物，而不是關注脂肪、糖類和蛋白質。」

迪爾德麗•託拜厄斯博士領導的這次研究基於來自68,000多個成年人的數據，他說：「沒有確鑿的證據建議人們安排低脂肪的飲食。」
Dr Deirdre Tobias, who led the research based on data from more than 68,000 adults, said: 'There is no good evidence for recommending low-fat diets.
1983年，政府的指導方針建議英國人脂肪攝入量減少到總能量的30%，並增加糖類攝入量。

然而並不是所有專家都被說服了，倫敦大學國王學院的湯姆•桑德斯教授說：「為了控制體重，明智的做法就是少吃而且避免吸收過多的脂肪和糖，尤其是肥肉、油炸食品、蛋糕、餅乾和含糖飲料。」
Not all experts, however, are convinced. Professor Tom Sanders, of King's College London, said: 'To control weight, it remains sensible to eat less and avoid consuming excess amounts of fat and sugar, especially as fatty meat, deep fried foods, cakes and biscuits and sugar-sweetened beverages.'
位於美國貝塞斯達的國家糖尿病、消化和腎臟疾病研究所的凱斯•霍爾在雜誌評論中指出，人們沒能減掉更多體重的主要原因是他們總是不到一年就放棄了。
In a commentary in the journal, Keith Hall, of the National Institute of Diabetes and Digestive and Kidney Diseases in Bethesda, US, said a key reason why people failed to lose more weight was that they had often given up before the year was over.
