@Adrian_Williams I agree with you…I wouldn’t eat a meal like that 90 minutes prior to start. I was given the advice from a sports nutritionist to eat 1g/kg carbohydrate 90 to 60 minutes prior to start…tried it…it just doesn’t work for me. But taking down 25g of dextrose 15min to 20min before start seems to work well.
One thing that struck me while I was poking around the Kraft Insulin study is the tremendous variability there can be in insulin response from individual to individual. My insulin response is on the fast side. I can eat a pasta/marinara meal and be back in the 80s mg/dl w/in 60 to 90 minutes. But definitely there are many people who have a much more delayed insulin response…so blood sugar can be elevated long after a meal.
Maybe that’s the source of confusion with pre-race nutrition. What works well for one may not work well for another…just due to individual variation of blood sugar/insulin response to a carbohydrate meal.
