I posted a similar post in another forum (athletic diabetics) and thought that to ask marathon runners.
I've tried low carb before (that is, between 70-100 grams carbs a day on most days, even dipping down to less than 70 grams carbs on some days). I was also training for a marathon. The results were not good for me. I was unhappy and was feeling sluggish and had no energy. I also had difficulty controlling my BGs.
Now, there's this book titled The Art and Science of Low Carbohydrate Performance (Volek and Phinney). Since the book specifically targets athletes, I thought it may be a good idea to give their plan a try and low carb another chance. From what I can work out, they are generally advocating less than 50 grams carbs a day (that would be really low, for me). They also go for high fat and low protein. Sorry, I can't remember the macronutrient ratios at the moment.
Is there any one who is eating less than 50 grams carbs a day and racing? By racing, I mean competing in athletic events, whether as a pro or an amateur. Athletic events can be running, swimming, cycling, triathlons, race walking, tennis, and so on.
If yes, would you mind sharing your experiences, such as:
(1) difficulties when initially adjusting to the less-than-50 grams carbs a day
(2) how long your adjustment was (the authors say 2 weeks)
(3) any adjustment to your training program as a result of changing your diet
(4) any problem you have encountered which may be related to the diet and how you deal or dealt with it
(5) effect on your racing time
Given my previous unsatisfactory experience with low carb while doing marathons, this time, I'd like to arm myself with as much info as I can gather. I'm looking for ways to improve myself and am willing to try new things provided I see some logical reason to try them.
Thanks in advance.
