Listener Q&A:

As compiled and read by Brock, the Ben Greenfield Fitness Podcast "sidekick".

Audio Question from Megan: When you do a big event like a marathon or Ironman in the days after the event is it true that you have a bigger caloric need. If so, what would the percentage be? She eats good/healthy food after the event but wants to know how much more she might need or not need to consume.

~ Resources I mention to Megan: Enerprime, Capragreens or SuperGreens, Tian Chi for adaptogenic herbs, Energy28 for Maca, Caprazymes and Caprobiotics, and Betaine HCL.

Audio Question from Josh: Can seasonal allergies cause his heart rate to get really really low? In April and May he can't get into Zone 4 or 5 while riding. His standing rate is 40 or 50 BPM!

Christian says: My wife and I ran a 1/2 marathon today. She appears to have a significant histamine reaction causing vasodilatation every time she runs significant distances. Her arms and legs turn purplish red and she feels her blood pressure drops. She dumps cold water on her arms each aid station and that helps some. The problem is worse when it is hot outside. Her hydration and nutrition are good. Her liquid nutrition has electrolytes and she adds a salt tablet to her water bottle. I recall your podcast interview about not needing electrolytes but adding salt seems to help her. What other thoughts do you have?

Audio Question from Brian: He is planning a 70.3 in January. Which program of yours would you recommend: Tri-Ripped or Triathlon Dominator?

Audio Question from Hunt(?): He recently watched "The Truth About Exercise" and saw a genetic test that can guess the potential of an individual's aerobic capacity. He's interested in learning more about that test.

Audio Question from Jerry: He fell 6 feet on to a mat while bordering which caused pain in the arch of his foot. He called it quits, went home and the next morning there was swelling and bruising (hematoma). He has been using ice, ultrasound and e-stim and is wondering if there are any other ways to speed up the healing?

Tommy asks: My wife is a runner and suffers from ulcerative colitis. She has a really clean diet no grains, no dairy or legumes. Her recent flair up sent her to the doctor and they put her on prednisone. 30mg 2 weeks, 20mg 2 weeks, 10mg 2 weeks. Within 24 hr of her first dose her symptoms were much improved. What side effects can she expect, will it effect her running? Is it possible to offset the prednisone side effects with diet and supplementation. What can she expect as the dosage decreases?

~ In my response, I recommend the GAPS diet.

Adam says: My wife suffers from migraines at least once every 2 months (usually once a month), to the point where she's bed ridden (normally a few hours) until she throws up then the pain subsides within an hour. The doctors reckon it could be her pill, but I wanted your take on it. She eats the standard typical high cho mod pro low fat (enjoys the odd egg) approach diet. Has no known illnesses. Is a fitness instructor and healthy. Have you heard of this before? Is there any known issues of substances or food groups that could induce this reaction?

Dylan says: I know some guys at my gym are talking this 7-Keto DHEA stuff up. Is it a scam? My number one goal is fat loss. If it can indeed increase my thyroid T3, I'll buy the mess out of it!

Phil asks:I am way into minimalist running shoes and use them all the time I am at the gym - for weight training, treadmill, elliptical, rowing. I use the Merrell Trail Glove, which looks like a "normal" shoe (no separate toe compartments). During the week, I try to mix up the cardio day-to-day. There are spinning bikes in the gym with toe clips and I'd like to add them to my cardio repertoire. Given my time constraints, I cannot switch to my (stiff) cycling shoes. So my question is - What are your thoughts on cycling (100 rpm hard intervals) in minimalist running shoes? I have tried the shoes without any problems, but I wondered if you knew of anything showing this to be contraindicated.
