I know certain carbs digest faster than others, but let's assume it's something like whole wheat bread...

How long does it take from the time you ate it until the time when it hits your blood and you can use them for weight training?
 
That's an interesting question.

If you are worried about energy supply during a workout, why not just remedy that by sipping dextrose/whey while lifting...then you won't run out and your muscles won't be hungry!

I really wanna know the right time to eat a good pre workout meal so that it's already being used when I get to the weight room...

Like I slam some whey right before I get into the gym, but I think that takes like 80 minutes for that to hit the blood..
 
The information I found was this:

The length of the carbohydrate chain is not responsible for the speed, in which the carbohydrates (because they are broken down fast) pass through the intestines into the blood, but the accompanying matter in the food, such as the dietary fibres, fat, and protein. They determine the dwell time of the food in the stomach, and thus the absorption by the blood.

In terms of a complex carb like whole wheat bread, I know it takes longer than a simple carb, but I assume the actual amount of time depends on the Glycemic Index of the food in question, that is, how quickly blood sugar/glucose increase after eating the food.

Good article :
 
Yeah, but that GI number doesn't easily translate into time...minutes, hours, whatever.

I think what he wants to know is, someone eats a cup of say, rice, how many hours until it's steadily broken down? This is deeper than I thought. Haha
 
Settle yourself, boy

Too many variables, not enough data available without extensive testing done on you.

Eat your spaghetti and chicken 2 hours before, and calm the **** down. :D

Anyway, it's the post-workout that most of the studies show matters. Pre isn't really all that important in anabolic activities. It's not like you need to blunt the sharp edge of The Wall like a marathon runner. Eating a big-ass bowl of pasta isn't gonna make much difference if your glycogen stores are already mostly full. Just make sure you replenish them after emptying them. Half your PWO during (sips, not gulps), and half after is the convention.
 
GI is a measurement used to tell you how much fluctuation you see in your blood glucose level when consuming said food.

100 has the most fluctuation.
100 = pure glucose

There is no reference to time in GI.

If there is a way to give a general idea of how long it takes for carbs to hit the bloodstream I would imagine that GI has some sort of impact on it though.

It would seem so...I will try and squeeze in time on this tonight...if it is possible in any way to find this time, I'll find it.

:)
 
If your diet plan is good, then you should have enough energy in your working muscles and in your liver for your workouts. Now, if you want a quick fix, try yogurt with honey and nuts an hour and a half before your workout.
