教授：看看這個早已經做了的實驗，對象不是老鼠，雞，兔子，是大活人

這些實驗對象還都是肥胖有病的人，叫他們吃低碳高脂飲食（50%的熱量來自飽和脂肪，很高脂），結果是血脂都減低了。

Abstract
OBJECTIVE:
To determine whether a diet of high saturated fat and avoidance of starch (HSF-SA) results in weight loss without adverse effects on serum lipids in obese nondiabetic patients.

PATIENTS AND METHODS:
Twenty-three patients with atherosclerotic cardiovascular disease participated in a prospective 6-week trial at the Christiana Care Medical Center in Newark, Del, between August 2000 and September 2001. All patients were obese (mean +/- SD body mass index [BMI], 39.0+/-7.3 kg/m2) and had been treated with statins before entry in the trial. Fifteen obese patients with polycystic ovary syndrome (BMI, 36.1+/-9.7 kg/m2) and 8 obese patients with reactive hypoglycemia (BMI, 46.8+/-10 kg/m2) were monitored during an HSF-SA diet for 24 and 52 weeks, respectively, between 1997 and 2000.

RESULTS:
In patients with atherosclerotic cardiovascular disease, mean +/- SD total body weight (TBW) decreased 5.2%+/-2.5% (P<.001) as did body fat percentage (P=.02). Nuclear magnetic resonance spectroscopic analysis of lipids showed decreases in total triglycerides (P<.001), very low-density lipoprotein (VLDL) triglycerides (P<.001), VLDL size (P<.001), large VLDL concentration (P<.001), and medium VLDL concentration (P<.001). High-density lipoprotein (HDL) and LDL concentrations were unchanged, but HDL size (P=.01) and LDL size (P=.02) increased. Patients with polycystic ovary syndrome lost 14.3%+/-20.3% of TBW (P=.008) and patients with reactive hypoglycemia lost 19.9%+/-8.7% of TBW (P<.001) at 24 and 52 weeks, respectively, without adverse effects on serum lipids.

CONCLUSION:
An HSF-SA diet results in weight loss after 6 weeks without adverse effects on serum lipid levels verified by nuclear magnetic resonance, and further weight loss with a lipid-neutral effect may persist for up to 52 weeks.

不是借此提倡每個人都吃高脂肪，而是覺得，人體營養學有很多誤區和未知未定論的東西。

所有跟帖： 

• 謝謝分享。這個研究樣本太小，時間也短，效果也不算特別明顯。還引起其LDL，HDL，TG指標的變壞，對此很有保留，有評論如下， -吃與活- ♂ (1108 bytes) () 09/05/2014 postreply 11:52:57

• 對不起，你是對的，後麵是說另外一個類似的diet的，不是這個實驗。 -吃與活- ♂ (0 bytes) () 09/05/2014 postreply 12:42:29

• 謝謝教授的回複和個人體驗的無私分享。你對老周的介紹也讓我對油脂碳水的作用再思考。 -Lily168- ♀ (0 bytes) () 09/05/2014 postreply 12:48:44

• 你逼著我又稍微仔細的看了一遍原文：）我不是做這類實驗的行家，但我覺得這個實驗確實說服力有限。 -吃與活- ♂ (661 bytes) () 09/05/2014 postreply 13:28:05

• 說的有道理。 -Lily168- ♀ (241 bytes) () 09/05/2014 postreply 14:23:45

• 但病人可能不習慣吃這種飲食，吃的就少。如果不是卡路裏攝取下降，病人又沒有增加鍛煉消耗卡路裏，減肥是不可能的。 -吃與活- ♂ (0 bytes) () 09/05/2014 postreply 14:50:10

• 周末愉快！有空請說說為什麽不大同意這個前提，我覺得可能很有意思。 -吃與活- ♂ (0 bytes) () 09/05/2014 postreply 20:24:16

• 6周的飲食改變，引起的效果維持了52周，“效果也不算特別明顯”？你當然可以保留你的意見。 -Lily168- ♀ (21 bytes) () 09/05/2014 postreply 12:32:55
