節食

歐美近年一直都流行多種減肥節食方法, 其中以四種最受歡迎:

Atkins, Ornish, Zone, LEARN (Lifestyle, Exercise, Attitudes, Relationships and Nutrition)


美國醫學協會期刊Journal of the American Medical Association (JAMA)最新研究發現, Atkins diet比其他三種方法更有效減磅, 亦對心臟更好. 但其實如果看清楚詳文, 筆者(Dean Ornish, M.D.)發現其實跟從Atkins diet的節食者一年後並不比跟從Ornish或LEARN diets的節食者更有成績, 卻只顯著比Zone diet的有效.

Dean Ornish認為JAMA的研究有太多錯漏, 它的結論亦誤導讀者. 例如研究沒有量度Atkins diet會帶來的心臟毛病, 卻只量度risk factors(如膽固醇過高等), 但他的Ornish diet卻明顯可以減低節食者的膽固醇, 且患過前列腺癌的病人跟從Ornish diet後都有好轉, 患糖尿病及/或高血壓的病人亦一樣有好轉或減慢惡化跡象, 但Atkins diet只會令心臟病更壞.

更重要是, JAMA的研究沒有探討各diet的效能, 只研究讀者單憑閱讀這四本節食方法的書能否持之以恆地跟隨. Ornish認為讀者當然更能跟隨Atkins的只吃肉的節食法, 因為容易, 但並不表示健康.

個人並沒有看過以上任何一本書籍, 亦沒有特別跟從過任何一種方法, 不過這幾年都少吃了澱粉質的食物. 始終均衡飲食最緊要, 只吃肉不吃蔬果澱粉質又不可, 完全不吃紅肉也不太健康.

mad dog,腳係cm係嘛?

atkins一睇知風險好大,同埋我一定唔用得,所以從來冇諗過要睇。:)

均衡+運動啦,法門一度,其他唔使記咁多。

I use Atkins reduce 30 lbs in 2 months before I got married. and then after married, I gain back 20 lbs. Now I reduce another 10 lbs by general healthy diets.(from 190 lbs to 160 lbs to 180 lbs to 170 lbs). (I was larger than 37, and now is around 33).

Conclusion: Atkins does work in very quick way. Atkins does come back very quick as well. The best is to have the healthy diet culture, but not a special diet.
