Transcript of Ben greenfield Podcast 50

  • Podcast #50 from http://www.bengreenfieldfitness.com/2009/07/brain/ Introduction: In this podcast episode: how to get smarter, the top 10 questions about fat loss, nutrition and human performance; information about the HCG diet for fat loss, how to shock your diet off a weight loss plateau, the link between magnesium deficiency and heart attacks in athletes and Listener Q and A on cafeeine , blood sugar levels during exercise, weight lifting for tritahletes, liquid vegetables and much much more. Ben: Wow, as you may have guessed from the introduction there is a ton to cover in todays podcast. This is in my opinion going to be one of our best podcasts ever and one of the reasons for that is this is the 50th episode and we didnt have a podcast last week. So Ive got to double up on the content. Before I get to anything, you know I know that some of you out there have had some trouble figuring out how to subscribe to the podcast or maybe didnt even know that you could subscribe to the podcast on something like iTunes and then some of you also didnt know that you could subscribe to the blog and you can literally get automatic emails whenever anything comes out. I just put the finishing touches on an update on the page that tells you how to subscribe, so if you go to www.bengreenfieldfitness.com, theres a really apparent link in the upper right hand corner that says how to subscribe. If you click on that or you know someone whos trying to subscribe and doesnt know how and they click on that its literally just like a 1, 2, 3 easy as pie way to make sure that you automatically get the free audio episodes and dont miss out on any of the content. So as I mentioned in the introduction to todays interview jam- packed weve got a featured topic which is an interview with Dr. Arlene Taylor. Shes one of the worlds leading brain experts. Brand spanking new Journal of Strength and Conditioning Research just hit the shelves. Im going to be bringing you the most relevant research from that. We have Listener Q and As on caffeine, liquid vegetables, blood sugar and weightlifting for triathletes and I do have some special announcements coming up as well and actually after I record
  • this podcast, I am throwing my podcasting equipment into a backpack over my shoulder and biking down to the local Farmers Market where a couple of weeks ago I came across a Native American fellow who was selling a topical ointment thats been passed down through his family for managing muscle inflammatory conditions and so Im going to find out exactly what hes putting in that stuff. So look for that next week along with a lot of other cutting edge next week including some information about water. Lets go ahead and move into this weeks content. Ben: This weeks Listener Q and A presents some pretty interesting questions from listeners and I want to start off with a question from Listener Andrew. Andrew asks: I was hoping you could clear up some confusion I have about caffeine. Currently I avoid caffeine at all costs. I consume no caffeine whatsoever. My question is if caffeine can be part of a good nutrition plan, would it be ok to have a cup of coffee each day? Or perhaps to begin drinking green tea? What is your opinion on the FRS energy products and the caffeine they contain? Ive heard glowing reviews of that product line even from Lance Armstrong himself. (Ooh la la, the Tour de France champion has endorsed it so it must be good.) Ben answers: We actually covered FRS energy drinks quite a bit. I dont want to completely blow off your question Andrew, but Ive covered those drinks twice in the podcast so far. So Im going to put a link after your question in the Shownotes but the synopsis when we covered is that the thing that makes FRS energy drinks unique is the component in them called quercetin and quercetin is actually an immune system booster you find in things like red onions and apples and it has been shown in research to help with immune system support, or the time that someone actually had a cold or the flu. But, the other things that are in the FRS energy drinks aside from of course the caffeine were a little bit suspect. Some artificial colorings, some artificial sweeteners that are suspect in terms of their health and of course the large amounts of sugar and typically the small amount of phosphoric acid and things of that nature that needs to be placed in a soda or energy drink. Caffeine in general is in my
  • opinion a great tool in your fat tool box, in your energy tool box. The problem is you cant overuse it. I personally do an 8 to 12 oz cup of coffee in the morning and occasionally in the afternoon if I have a very busy day or very hectic day I will do an energy drink thats the equivalent of about one quarter cup of caffeine and its a green tea based energy drink. I use one called Delta-E. It happens to be the same one that Dr. Arlene Taylor also uses. Shes the lady that I interviewed today. But thats one that I use. Caffeine is something thats beneficial. If you build up a tolerance to it, its not that beneficial and you could actually do a little bit of damage to your liver and your kidney if youre one of those people thats consuming three 30 oz cups of coffee during the day. But a little bit of coffee to give you a jumpstart is great. It has whats called a glycogen sparing effect, meaning that it helps you to burn less carbohydrate, a little more fat. It helps with your focus, it helps with your energy levels. It helps stimulate your central nervous system which is a good thing in a lot of cases, especially for those of us who need a little jumpstart to our day. So absolutely I do condone the use of coffee on a limited basis. As an athlete I do abstain from coffee for at least 7 days prior to competition and then I take it on the morning of the competition. So you can use it as whats called an ergogenic aid as well. For more information specifically on what my opinion is on the FRS energy products that Im not super convinced Lance actually uses write into me if youve seen him drink it. All Ive seen is him endorsing it but I didnt see him suck one of those down before the individual or team trials in the Tour de France this week yet. So, listen in to my previous podcast about that Andrew. Great question. Amy asks: Id like to see if you can clarify some information Ive been hearing. Set me straight in other words. Ive heard if your blood sugar is between 70 and 90 before you exercise, you will burn more fat. That is apparently the optimal level for burning the most fat. Can you confirm whether what Im hearing is true or false? Also Im told that you are supposed to drink your blood sugar level 20 minutes before exercise. Ben answers: Amy, I dont know if youre diabetic and thats why someone was talking to you about this, but for those of us who are not
  • diabetic, checking our blood sugar levels, monitoring our blood sugar levels before and during exercise is really not necessary. Granted you could get it to an ideal level, but in most cases our body, if it is insulin sensitive and if it does operate directly which it does not if you have diabetes type 1 or type 2 then your blood sugar levels as long as youre eating a healthy diet are going to be right where they need to be. However, I want to answer your question a little more specifically. You say that youve heard that blood sugar levels are supposed to be 70 and 90 before you exercise if you want to burn more fat. Well yeah, 70 and 90 its called milligrams per deciliter in terms of your actual concentration, but 70 to 90 is low. Ok? You are going to tap into your bodys fat reserves because you dont really have much carbohydrate cir
