贊成的部分就恕刪了,僅留有不同意見的部分,請兩位見諒 Orz
※ 引述《IDfor2010 (116)》之銘言:

: : 1.變瘦
: 嗯... 還是要靠運動
斷食和運動的主要目的,都是在「增加身體的胰島素敏感」。
在斷食的世界觀,運動不是主要項目(只需適量、強度達標即可),重點是在
如何調控體內胰島素水平。
: : 2.讓胰臟休息,降低相關疾病發生率
: 讓胰臟休息? 應該不是這樣... 應該是讓胰臟運作,不會一直處於高血糖狀態
斷食是讓胰臟減少胰島素分泌,換言之就是讓胰臟休息。
胰臟是會隨年紀退化的,當年紀越大,如果控糖/醣沒做好,只會讓胰臟負擔
越來越大,造成一些不可逆的後果;斷食、控糖/醣是讓胰臟休息的最好方法。
: : 3.飢餓感會活化體內的修復細胞,讓身體變健康變年輕
: 沒聽過,不予置評。
: 不過飢餓,會讓一些細胞不好修復倒是真的。
摘自斷食大神 Dr Fung 的著作「The Obesity Code」:
“GROWTH HORMONE is known to increase the availability and utility
of fats for fuel. It also helps to preserve muscle mass and bone
density. Growth hormone secretion is difficult to measure
accurately because of its intermittent release, but it decreases
steadily with age. One of the most potent stimuli to growth
hormone secretion is fasting. Over a five-day fasting period,
growth hormone secretion more than doubled. The net physiologic
effect is to maintain muscle and bone tissue mass during the
fasting period.”
簡單翻譯,就是生長荷爾蒙的分泌會隨年紀減少,而刺激方式之一就是斷食。
斷食的第 5 日,生長荷爾蒙會增加一倍以上。
大餐會抑制生長荷爾蒙,斷食則移除了這個抑制,可讓身體自然的增加分泌。
: : 4.腦部腺體分泌發生變化,促使人精神更好,並產生愉悅感
: 沒聽過
: 運動是刺激腦部 腦內啡 多巴胺 分泌最好的春藥
: 其次是看A片打手槍
: 吃東西也會 讓腦內啡物質分泌 但不管看A片打手槍還是吃美食,怎樣都沒運動的效果好
: ---
: 飢餓或太久沒吃東西 可能會導致 體內腺體分泌出現問題 例如:憂鬱
這段引用自 Dr Fung 的「The Complete Guide to Fasting」,抱歉落落長...
“Animal studies show that fasting has remarkable promise as a
therapeutic tool. Aging rats started on intermittent fasting
regimens markedly improved their motor coordination, cognition,
learning, and memory. Interestingly, there was even increased
brain connectivity and new neuron growth from stem cells.
A protein called brain-derived neurotrophic factor (BDNF), which
supports the growth of neurons and is important for long-term
memory, is believed to be responsible for some of these benets.
In animals, both fasting and exercise signicantly increase the
benecial BDNF effects in several parts of the brain.
Compared to normal mice, mice on an intermittent fasting regimen
showed less age-related deterioration of neurons and fewer symptoms
of Alzheimer's disease, Parkinson's disease, and Huntington's
disease. Human studies on caloric reduction find similar neurologic
benefits—and since fasting certainly restricts calories, this is one
area where fasting and caloric reduction provide similar benefits.
With a 30 percent reduction in calories consumed, memory signicantly
improved and the synaptic and electrical activity in the brain
increased. In addition, insulin levels have an inverse correlation
to memory—that is, the lower the insulin level, the more memory
improves.”
簡單翻譯:實驗發現斷食的老鼠,有較佳的動作協調性、認知能力、學習及
記憶力,原因是斷食使 BDNF 因子增加(對神經生長及長期記憶非常重要的
蛋白質),減少了阿茲海默症、巴金森氏症以及舞蹈症;減少人類熱量攝入
的一些研究也發現類似的助益,斷食基本上也算是減少熱量攝入的手段,所
以跳 tone 的結論就是:減少熱量等於降低胰島素,也就等於增加記憶力。
: : 5.降低壓力,調整作息,精神、睡眠品質變好
: 沒聽過
: 睡眠品質變好、精神變好,或許是成功減肥,呼吸中止症、打鼾、肝發炎的症狀減緩
: 不是不吃東西的結果
應該是反過來說,恢復正常生活,減少壓力荷爾蒙之後,胰島素水平自然也會跟
著下降。
蓋:壓力荷爾蒙會升血糖,血糖升高自然胰島素水平就會高,久而久之阻抗發生,
無法消耗掉的血糖就會儲存成脂肪。
: : 4.有任何後遺症嗎?有沒有什麼資料上故意不寫出來的東西?
: 注意腦部狀況
請參考前面所述,腦部是不會有奇特狀況的,請放心斷食。
