This was a phenomenally well-designed trial.

這是一項設(shè)計得極為出色的試驗。

People did change their diets according to their group assignment. Those in the low-fat group consumed, on average, 29 percent of their calories from fats, versus 45 percent in the low-carbohydrate group. Those in the low-carbohydrate group consumed 30 percent of their calories from carbohydrates, versus 48 percent in the low-fat group.

人們的確會根據(jù)分組改變自己的飲食。低脂組的人消耗的熱量平均29%來自脂肪，低碳水組的人45%的熱量來自脂肪。低碳水組消耗的熱量30%來自碳水化合物，低脂組48%的熱量來自碳水化合物。

They did not, however, lose meaningfully different amounts of weight. At 12 months, the low-carbohydrate group had lost, on average, just over 13 pounds, compared with more than 11.5 pounds in the low-fat group. The difference was not statistically significant.

然而，他們的體重減少并沒有什么實質(zhì)性的不同。在12個月時，低碳水組平均只減了13磅多一點，對比低脂組減少了超過11.5磅。該差異沒有統(tǒng)計學(xué)意義。

Insulin sensitivity didn’t make a difference. People who secreted more or less insulin lost no more or less weight in general on either a low-fat or low-carbohydrate diet. Genetics didn’t make a difference either. People who had genes that might indicate that they would do better on one diet or the other didn’t.

胰島素敏感性并沒有影響。人們分泌的胰島素不論多少，在低脂或低碳水飲食中的減重差別都不大?；蛞矝]什么差別。一些人有的基因可能意味著他們會在某類飲食中表現(xiàn)更好，而在另一種飲食中則沒那么好。
