| Your breakfast seems very low carb for someone burning that many calories in a workout. That means your body is either going to get the carbs from food (you aren't giving it many carbs) or from a liver-dump...you are probably releasing glucose during your workout.
This sounds contrary to what a lot of people say on these boards...(I'm not a believer in extreme low carbs when exercising)...but try just a few more carbs before workout. I find that keeps my numbers pretty even and I don't crash too much afterwards...or have a high increase afterwards.
I'm not talking about carbo-loading for a marathon.
I read years ago that Martina Navratilova (sp?) ate a bagel before every match...what is that, about 45 carbs? She burned that off for energy...but bagels are a pretty slow burn which messes up most of our numbers if we eat an entire bagel.
Try maybe 1/2 bagel before working out? |
