00:01 Welcome back we've been talking with Dr. Neil Nedley
00:03 and we've talked about some exciting things 00:05 we're glad you're with us Dr. Neil Nedley. 00:06 Well, thank you it's good to be here Don, as always. 00:10 Now let's continue our discussion 00:12 we have some other studies to look at, 00:13 we want to look at sports and the placebo effect. 00:17 Yes, it's kind of interesting 00:18 we've looked at placebo effect as far as diseases concerned 00:21 and that's why we do what's called randomized studies 00:25 where if we really want to see of something 00:27 it's beneficial like we've just looked at 00:30 red yeast rice for instance, 00:32 we take it and compare with a placebo 00:34 and then do a comparison study and the individual doesn't know 00:38 if they're getting the active component 00:40 or the placebo in that way 00:42 we can see is a due to their 00:44 believe the things got better 00:46 or is it actually due to something beneficial 00:48 in the product. Okay. 00:50 And in that case the American Journal Cardiology reported 00:53 that red yeast rice extract was indeed very beneficial. 00:59 Again as compare to placebo. 01:00 But we haven't really done placebo studies 01:03 as far as sports enhancement is concerned. 01:06 So this is like whether not sports, 01:08 sports enhance your physical well being. 01:11 Well, you know this is like taking products 01:13 for sports enhancement you know. Okay. 01:15 For instance the weight lifters 01:16 have a tendency to wanna steroids 01:18 or... Okay, absolutely. 01:19 They want to take growth hormones. 01:20 In fact, this study that you're seeing 01:22 the graphic upon the screen 01:24 shows the Athletic Boost from Growth Hormones 01:28 actually is not due to the growth hormone. 01:30 It's mental. It's mental, in other words 01:33 it's to belief that the growth hormone is going, 01:35 is going to help that actually built those muscles up 01:39 to a stronger component. 01:41 And they did the study that showed this. 01:43 Yes, they did a study 01:45 by injecting either growth hormone into the individual 01:48 or growth or actually a placebo 01:50 where the individual thought 01:52 they were getting growth hormone. 01:53 And then they compared the two groups 01:55 and what they found out is everyone in the study 01:58 whether they were in a placebo arm 02:00 or the growth hormone arm 02:02 improved about one to two percent 02:04 as far as muscle performances concerned 02:07 and Athletic performance, 02:09 but if you are in the placebo group, 02:11 in other words, you wrongly thought 02:13 that you had received growth hormone 02:15 your performance enhancement was twice that 3 to 5% 02:20 and the phenomena was far greater 02:22 in men than in women often we say that women 02:26 are more pronto placebo effect and the mental belief aspect 02:30 but as far as athletic performances concerned 02:32 men are actually more pronto to it. 02:34 So what do you make of these kind of studies 02:36 because what you're basically saying is, 02:38 you know, these things are really help you 02:40 that's what you're saying, 02:41 but what do you replace it if they thank it's helping them 02:46 and it's not the thinking that was helping them 02:49 is what health plan and if you take that away 02:51 then they're not gonna get help this much, so what do you do? 02:54 Well, I think the point of the study is 02:57 that the mind plays amazing tricks on the body. 03:00 And the placebo effect has been known for centuries, 03:03 but it also you know, that the take home message 03:06 and that says just because someone makes a claim 03:09 that a product helped them doesn't necessarily mean 03:13 that their product really helped them. 03:14 And last they really enrolled in a study 03:16 and that's the importance of scientific studies 03:19 where we can involve groups of people 03:22 and actually do comparison 03:23 and it turns out for those of you 03:25 that are in sport don't take growth hormone 03:27 actually just belief that what you're doing is helping 03:31 and you'll do better than growth hormone. 03:32 So that's it, that's the answer 03:34 just belief on the basis of what you've said 03:37 and instead taking the stuff 03:39 that really could be quite damaging. 03:40 Correct. Okay. Correct. 03:42 All right, well let's go to the next one 03:44 I think it's fascinating as well 03:45 and it had to do with the relationship 03:48 between exercises increase protein, 03:51 what was this study about? 03:53 Well, it show that exercise increases 03:56 in important protein called BDNF. 04:02 And in fact, that right there on the screen 04:04 that you can see Exercise Increases that Protein 04:07 and the importance of BDNF 04:10 actually is not only that it helps the brain 04:14 in fact, the term for BDNF 04:19 is Brain-derived neurotrophic factor. 04:22 Brain-derived neurotrophic factor, 04:26 which means I can understand the brain and it's derived 04:29 from a... from a neurotrophic factor. 04:34 Well, neurotrophic means 04:35 it actually supplies the neurons with nutrition. 04:39 That they need. Exactly, 04:41 it's a factor that helps the neurons to work better. 04:44 So in other words, if you exercise the B 04:46 this particular BDNF goes up 04:49 and lessens the appetite. That's right. 04:53 And so lot of people think well exercise is only 04:57 you know taking away maybe if you for instance, 05:00 if you do brisk walking for an hour a day 05:02 which is quite a bit of brisk walking 05:04 you've only lost about 500 calories by doing that. 05:07 And so people say, well you know, 05:09 exercise may not be all that important in weight loss 05:11 it's a whole lot easier 05:12 to not eat those two slices of American cheese 05:16 that are worth to 500 calories 05:18 then they go out and walk for an hour 05:20 and so the secret is to really cut down on what you're eating, 05:25 but this shows that when we do exercise in proper ways 05:29 we actually secrete a chemical that helps us not to over-eat. 05:34 Interesting, can we just get that 05:36 chemical without having to exercise, 05:37 can we get it off the shelf just like everything else? 05:39 Well, not necessarily 05:42 exercise is a good way of doing it, 05:45 but also weight loss in and of itself can do this 05:48 you know intermittent fasting, 05:50 okay, can increase BDNF. 05:52 But there is no way to get this particular hormone. 05:56 No there is, it's not in the bottle 05:57 it's not in a supplement. 05:58 Yeah, that's only made by the brain. Okay. 06:00 And so at this point in time we haven't found out, 06:02 in fact it's really hard to get proteins 06:04 like that into the brain 06:06 even if you word a consumer in a bottle 06:08 because it won't cross the blood brain barrier, 06:10 these proteins have to be made inside the brain. 06:12 I see. And never any affected, okay. 06:15 So this study if I want to read more about it, 06:17 where do we get the studies from? 06:18 Well, this particular study 06:21 was done by Dr. Henry Anhalt of the Animas Corporation. 06:27 He is from West Chester, Pennsylvania. 06:29 And actually wasn't publish 06:31 it was presented at the Endocrine Society's 06:33 2008 meeting in San Francisco 06:36 it probably well republished forth coming. 06:39 fascinating, so get out their exercise 06:42 secrete the hormone you need. Yes. 06:45 And this will not only help you loose those calories, 06:48 but keep helping you not be you know given to over eating. 06:53 That's right, exactly. 06:56 Physical exercise and recovery of cancer patients. 07:00 Yes, a lot of people just have this assumption that you know, 07:03 I'm diagnosed with this deadly cancer. 07:05 And I just need to take life easy 07:08 you know I shouldn't be stressed, exercise is stressful 07:11 and you know I just need to get the treatment radiation 07:16 like chemo whatever treatment I'm and kind of take life easy. 07:19 It turns out those individuals don't do near as well 07:22 as those who actually start a physical training program 07:27 even in the midst of their chemo and radiation 07:29 they start a physical training program 07:32 as part of what we called Cancer Rehabilitation. 07:37 So even though you're down you have those treatments 07:39 or whatever you're going through get out there 07:41 and still exercise regardless 07:43 of how you feel it's gonna help you. 07:45 These people showed significant improvements 07:47 in physical function. 07:49 These physical improvements lasted for even three months 07:52 after the training program was over with compared 07:54 with those at least three months, 07:56 they only did the study three months afterwards. 07:58 And they also found out that they did better emotionally, 08:03 they did better physically 08:05 and exercise is a very important component 08:08 actually pushing it 08:09 and even getting involved in group activities 08:12 social types of exercise seem to benefit 08:16 these cancer patient as well not just the individual exercise. 08:19 And that study is from where if we want to read more about it. 08:22 That study was published in Psychosomatic Medicine 08:24 in May of 2008. Fascinating okay, 08:28 one last study before we finish today's program 08:32 and that is too much sleep increases stroke risk. 08:35 Too much sleep, 08:37 yeah a lot of times we talked about too little sleep. 08:39 But this study show that regularly getting nine hours 08:43 or more of sleep per night increases the risk of stroke 08:46 in postmenopausal women. 08:48 So now it was after the change. 08:50 After the change. 08:51 It's okay to sleep a lot before the change. 08:53 Well, now studies have actually shown in other ways 08:57 too much sleep is harmful 08:58 can actually lead to depression for instance. 09:00 But only 5% of women age is 50 to 79 09:04 are getting too much sleep. 09:06 And so it's not a large group but the study showed 09:11 that they had a 60 to 70% higher risk of stroke 09:15 that significant. That's huge. 09:17 Even those who get too little sleep 09:19 only have a 14% increase risk of stroke. 09:21 So we know too little sleep is bad, 09:24 but that increases the risk of stroke slightly 09:26 if you get too much sleep 09:27 it increases the risk of stroke pretty dramatically. 09:31 Tell us with that studies from then I have a question for you. 09:34 Well, the study was actually presented 09:37 by Sylvia Webster high, smaller 09:40 of Albert Einstein College of Medicine in New York 09:43 and it was presented 09:44 at the American Heart Association journal Stroke 09:48 in this would have been July of 2008. 09:51 So what's too little sleep, what's too much sleep, 09:55 how many hours is the right amount of sleep? 09:57 Too much is greater than nine, 09:59 too little is greater than six. Great. 10:02 I'm sorry less than six. 10:03 Yeah, less than six greater than nine 10:06 and most people need about seven to eight 10:08 that seems the eight hours 10:10 point seems to be pretty idea for most individuals. 10:13 And to get that readjusted if you're off, 10:16 what's the best way to get a readjusted? 10:19 Light therapy actually, believe it or not 10:21 and if you get light therapy in the morning 10:23 it set your body clock you're tired in the evening 10:27 and you're able to go to sleep much better. 10:29 So open up those drapes 10:30 and turn to those bed lights on and then reset your clock. 10:33 In the morning, that's right. 10:34 And then even a mid-afternoon exposure can be helpful. 10:37 Well, Dr. Nedley you've updated to some a lot of different areas 10:40 and then very useful information no matter 10:44 you know, if you're someone was taking maybe 10:46 growth hormone to get stronger or anything else. 10:49 We're glad that you've been with us today, 10:50 thanks for being with us. 10:51 Thank you very much, Don. 10:52 And thank you for being with us today, 10:54 we hope that you know, you'll take these things 10:57 to heart anything from red yeast extract, 11:02 a very positive substance 11:04 or and any of these other just great tips you've heard today 11:06 and as a result of this program 11:09 you have health at last not just for now, but for a lifetime. |
