    Diabetic rider badly needs nutrition advice

    So I have been mountain biking casually for several years. But this year I've kicked it up a couple notches and decided to train hard and ride as hard as I can. I tend to get my ass kicked by my diabetes most of the time. One of two things happens. I start with a normal blood sugar, and end up with a severe blood sugar crash that leaves me ruined. It happens even if I am pulling gatorade from my camelbak. Its just not enough to keep me sustained from a normal blood sugar. The other thing is I try to load up on carbs beforehand, my blood sugar goes high and I dehydrate from it in 30 minutes of hard riding or less. I can't seem to walk the line. Any other diabetic riders out there have any advice? Thanks in advance - Scotto

    From my experience, don't load up on carbs before you start, but take enough to replace them as you ride. I check my glucose level before I leave. If it's normal, I'll bring a Powerbar and/or a pack of energy chews (like Gu Chomps) for every 45 to 60 minutes I expect to be out, and then one more in case I end up riding longer. It's very important to replace carbs as you ride, especially if you're grinding up a long hill, or spinning on a fast flat.

    Your ratios are probably different. One book that really helped me get it figured out was The Diabetic Athlete's Handbook by Sheri Colberg. The first few chapters are full of general information, then she goes into specifics for each sport. It's a lot of good info.

    I had a lot of similar sounding problems last year, when I was first starting out on longer rides. I read that book during the winter, and haven't had any issues this year.

    You'll need to figure out how many grams of carbs to eat each hour. That book has tables based on your weight. Powerbars and Clif bars seem to be better for keeping my levels normal as I'm riding. If I do feel low, energy gels or chews seem to bring it back up more quickly than Powerbars, which is why I carry both.

    The key is to eat something before you crash. I listen to music on my phone while I ride, and I sometimes set a reminder to go off in 60 minutes. Otherwise, I'm tempted to keep going until I feel woozy, which is not very safe.

    Authalic thank you so much for the timely and wise advice. I appreciate hearing from other riders who have the same challenges and have been able to get past them. That book is something I have seen mentioned in several other threads I read about this. I will certainly be picking that up. Thanks again for the timely response.

    One thing that helps stabilize blood sugar levels is a good fish oil supplement, it certainly wont fix your problem but it can help. One brand that is very good is nordic naturals.

    Do you have scientific research demonstrating a link between glycemic control and fish oil supplementation?

    I am not aware of this information and it would be interesting to read.

    Yes I'm using Levemir 25u AM and 25u PM.Not sure if I can use fish oil supplements. I've had an intermittent allergic type reaction after eating seafood. Not sure if a fish oil supplement would set it off, but a bit nervous about trying it. I can hardly wait to get my hands on that book. Ordered it off amazon the other night.

    I haven't biked with any diabetics, but i've played other sports with them. For the most part they got by with gatorade. Some sort of sugary energy chew would probably be good too, but you would need a more liquid to help digest etc. If it were me I would try drinking more gatorade, but I know sometimes that bloaty feeling sucks.

    Have you talked to a doctor or dietician?

    Trial and error Scott. There is no easy answer and all our bodies respond differently. Also as soon as you have it figured it may change.

    Personally, I pack a pound of candy just incase, test often, have a small snack before riding and back off insulin pump.

    Have fun.

    Thanks for all the replies folks. I did receive the book "The Diabetic Athlete's Handbook" that Justin recommended, and I must say it is a wealth of knowledge. I have already seen some improvement, having been on two rides with no blood sugar crashes or extreme highs. Still not really dialed in, but definitely a small improvement. Lahrs is right, trial and error, but mostly error so far. The book does provide a great foundation to work from. Mountain biking is so weird to deal with because of the sudden extreme extended bursts of energy with the not so intense periods in between. I've been able to play football and do long periods of manual labor without having this problem, but mountain biking brings it out. I pack a big bag of skittles in my saddle bag and a packet of gatorade chews in my pocket. The skittles are a last resort. I usually fill one bottle with gatorade and wear my camelbak with water. The gatorade alone cannot keep my booldsugar stable and it tears up my stomach while working out. I found something new called Skratch, a hydration formula full of natural complex carbs. I'm going to give it a try.

    Skratch Labs is awesome. My favourite drink. It doesn't give me gut rot like Gatorade etc. I mix it stronger on hotter/harder days.

    Like I alluded to before, once your body gets used to the harder riding it will hopefully not drop bsl as much as it does initially.

    Cheers.

    so I'm not the only person who feels like I've been kicked in the gut if I drink Gatorade while working out? Haha! I thought I was just a freak. I see so many people drinking Gatorade without any problem.

    with 25 units of Levemir morning and night I would assume Type 1, but I don't know the doses some Type 2s are taking...

    I would suggest talking to your Dr, or a nutritionist.
