我的问题是基于空腹饮用是否有效为前提。
我的疑问是在于,牛奶不建议空腹饮用,不然如同白开水被排出。
那么同样的道理是否APPLY在 PROTEIN SUP呢?
因为我没有饮食这些PROTEIN SUP的经验与知识。
也找 ...
如果你只是关心空腹吃有没有效果,根据insulin spike的生理的现象来推论,那么我可以可以告诉你,是的。YES。其实空腹吃会更好。
这是因为,葡萄糖是GI值100的东西,也就是说最快引起血糖反应的东西(所以你可以知道它会很快速让身体吸收)血糖升高就会造成胰岛素的释放。
OK, 现在假设你吃其他的食物,其中有纤维的,那么这些纤维质或者其他食物如脂肪或者甚至蛋白质会降低GI值(燕麦是低GI高碳水化合物的食物,其中一个原因就是富有纤维),胰岛素反应就慢。那么我们就不能好好把握这metabolic window (45分钟黄金时刻)或许会错失这机会。
对于whey protein,根据John ivy ,professor of kinesiology & health education,university of Texas 说"。。it is extremely digestible。。it is fast acting because it empties from stomach and is absorbed into the blood stream faster than other proteins。。" (Nutrient timing,pg60-61)
Lord ,你的质疑精神是很好的,我也尝试回答你的问题。不过如果你觉得不太满意,你可以继续在网上找更多的这topic的资料,它们的讨论或许也应该会深入和精确。说实在的,如果你打算好好的了解这个topic,algorithm所说的pre and post workout nutrition, insulin management , micro and macro nutrtion 都是重要的。 |

回复 160# Lord40892 的帖子
突然的想到你所说的那个"营养学的说法"--年前的营养学说,早上空腹饮食牛奶,会让牛奶在还没被吸收就被排到urinary bladde--
请问下,小baby都喝牛奶,没有什么固体食物,所以也可以说"空腹饮食牛奶",那么,你认为小baby喝的牛奶里头营养有没有吸收到? |

谢谢你尝试回答我的疑问。
我只是不喜欢某人自以为是的态度而已。
你说的我都略知一二。我的确实受不了那些一直叫人家去找去看的人。
做得版主,你以为我是那些只等spoon feed 的一群咩?

刚刚看到此贴,请容许我转贴跟大家分享。
Stop Wasting Your Protein Powder! How To Squeeze More Results Out Of Each Scoop Of Protein Powder You TakeBy Nick Nilsson Without knowing when and how to take your protein powder
for best results, you could be flushing your gains
directly down the toilet!
It doesn't matter what brand or type of protein powder you take...if you are taking it at the wrong time, you aren't getting as much out of it as you could be. In fact, if you take your protein powder at the wrong time, you may as well just dump it in the garbage!
Here is a list of the when, why and how of effective protein supplementation, ranked in order of importance.
1. Immediately After A Workout
If you only take protein powder once per day, this is the absolute best time to take it. Immediately after you finish your workout, your body needs raw materials to rebuild and recover with. If you don't supply the raw materials through eating, your body will break down muscle from elsewhere in your body in order to rebuild the damaged areas. This is very counterproductive as you can well imagine.
By taking in some protein (20 to 30 grams or so) within minutes after exercise, you provide your body with the raw materials it needs to recover without breaking down its own muscle tissue.
2. An Hour After A Workout
About an hour following a workout, your body has settled down from the excitement and is ready to really start rebuilding. The protein that you took in immediately following the workout has been metabolized and your body is looking for more. Another protein shake at this time is a good way to help speed recovery. Try to take in another 20 to 30 grams about an hour after working out.
3. First Thing In The Morning
Immediately upon waking, or as soon after that as you can manage, take a scoop of protein powder. Your body has just been through an (approximately) 8 hour fast and is hungry for nutrients. Feed your body!
Protein powder is more quickly assimilated than solid food and gets into your muscles faster. This protein shot gives your metabolism a boost, which can help with fat loss. Be sure to follow it with a good breakfast, of course.
4. Last Thing At Night
Prepare your body for the long overnight fast by giving it a little something to work with. A good combination for this purpose is to mix a scoop of whey protein in with a small glass of milk.
Whey is what's known as a "fast" protein, meaning that it's digested quickly, while milk protein (casein) is what's known as a "slow" protein, meaning it's digested relatively slowly. At night, you want your protein to be metabolized slowly so that your body gets a more even supply over the course of the night. By mixing "fast" and "slow" proteins, you get the benefits of the higher-quality whey with the slower digestion time of the milk.
5. In-between Meals
A quick protein shake can be a great snack in between meals. It helps keep your body supplied with protein all day long. This is especially useful if you tend to have long periods of time in-between meals. It could mean the difference between losing muscle and building or keeping muscle!
6. With Meals
Taking a protein supplement with meals is a handy way to increase the protein content of a meal. This is perfect for when you eat
a meal that is somewhat low in protein.
7. In The Middle Of The Night
This is a trick that bodybuilders sometimes use in order to keep their muscles supplied with protein throughout the night. Keep a pre-mixed protein shake right beside your bed. Although some trainers have been known to set alarms to wake up to drink it, I prefer to have it there waiting just in case I wake up, but I don't try to wake up on purpose. If I don't wake up, it's right there ready for me to drink first thing in the morning! This strategy is more targeted for muscle growth rather than fat loss.
WARNING!
Never drink a protein supplement immediately before working out!
Some people do this thinking that it will give them an energy boost or give them a head-start for post-workout recovery. Basically, all it does is sit in their stomach and bloat them up. Valuable blood that should be going to working muscles gets sent to the digestive system to try and digest it. The same warning goes for taking protein during a workout. Don't do it!
Taking protein powder is not going to make up for poor diet or a bad program but it can definitely help to support you in your training efforts. Take it at the right time and you'll get the most bang for your buck! |

减肥与增肌是相当对立的事情,因为这两件事情最终是基于一个生理现象-热量的供给和需求。
而热量的来源(不管是脂肪,蛋白质 或者是碳水化合物)是不需要理会的。
有氧运动,如果是运动持续时间过久对肌肉耗损特别大。有研究指出跑步里程和跑步强度比较起来,前者格外地破坏肌肉。(跑步里程也可以转换为时间,另外,这不是说跑步强度不会损坏肌肉,只是没有那么严重)
如果这是正确的,那么一个strength athlete 就应该限定他/她的有氧运动时间。不过这惟恐会降低欲减肥的作用。(燃烧不够脂肪)但是,如果做强度很高的cardio 运动,也可以在比较短的时间内,达到燃烧更多的热量的效果。这是因为在低强度的运动当中,如慢跑,虽然会动用到更多储藏的脂肪,(脂肪和碳水化合物,蛋白质比例成份)不过所需要燃烧的热量per unit,是很少。比较起来,总数燃烧比高强度低。
那么,strength athletes要减肥,选择做高强度时间短的cardio 运动是比较明智的。
高强度可以通过interval training 来达到。
我觉得还有很多生理机制没有说明,所以可能会有一些混乱。。不过这很花时间和精神,容许我将来有空再谈。。
糟糕。这就是我现在做着的东西...ori大大,找一天我po我的照片和写下我的生活作息。麻烦你给我一点意见可以吗? |
