Dextrose post workout

Post workout I have about 60 grams protein and 60 grams dextrose in my shake. Long term will this high sugar intake be bad for me?

I know having sugar all the time and throughout the day is bad, but if it is post workout only will I have problems with diabetes and other things if I continue this?
 
here is the formula take your lbs divide with 2. than that number X 0.5
that is how much u need dextrose.
if u lifted heavy u will not get fat from dextrose cause it goes directly to your muscles
 
I'm curious on this as well - anyone have any studies showing this dextrose intake post workout won't be harmful in the long run? I know some people are taking +100 grams of dextrose post workout.
 
Too many simple sugars post-workout will decrease your insulin sensitivity, add to your fat stores, and increase the risk of diabetes. That much is common sense.

However, your muscle glycogen stores are empty post-workout; plus, your muscles will be growing, and they need the carbs for that; proper amount of simple carbs, including dextrose, will not be harmfull.

You should be using a 50/50 dextrose/maltodextrin mix, by the way, not just dextrose itself.
 
Written by Bryan Haycock....

"There has been some controversy about which type of carbohydrate is best for post exercise glycogen replenishment. Some argue that simple sugars such as dextrose are best after exercise. Others say that drinks with glucose polymers are best. Still others say that there is no need to buy fancy sports drinks and that simply eating a meal high in carbohydrates such as pasta or rice is sufficient. Studies have shown no difference between different types of carbohydrates eaten post exercise and the rate of glycogen replenishment as long as sufficient quantities of carbohydrate are consumed (Burke 1997). "

That's the thing though - your muscle glycogen stores won't be empty after working out, unless you ran a marathon or you're been on a CKD diet.

"You should be using a 50/50 dextrose/maltodextrin mix, by the way, not just dextrose itself."

Why?
 
I think the reasoning is that malto is a complex carb and dextrose is simple, but I don't see why that would matter. Both have a gi of 100 or 100+ if I remember correctly.

I am curious as to the reasoning as I do not even remotely claim to know everything about this.
 
Adding maltodextin, which is a complex carb, would decrease the osmosity of the solution, which will help with the proper timing of gastric emptying.
 
Here is the formula for post workouts:

(based on total reps in your workout):

CARBS:
12-72 Reps - 0.6 grams per kg of lean body mass
73-200 Reps - 0.8g/kg/LBM
200-360 Reps - 1.0/kg/LBM
360-450 Reps - 1.2/kg/LBM

PROTEIN:
0.6 grams per kg of lean body mass.

30-40% of carbs should come from fruit juices such as pineapple or grape juice, while the rest should come from Dextrose/Maltodrexin.

By the way, this is from Charles Poliquin who trains David Boston of San Diego Chargers, Chris Pronger of STL Blues, and many other athletes. He is well known and has written many books on fitness, nutrition and weight lifting. You may need to adjust it to your body.

Also, the key time to take protein and the rest of the carbs in is approx. 50 minutes to 1 hour after the Dextrose. This is when the Insulin spike is greatest.

whey protein with dextrose is probably the best thing for you after you workout, along with some bcaa's and l-glutamine, thats the one time your body will just soak it up and is desperate for the sugar and protein...the amount of protein seems high though but im not sure what your goal is - generally a 35/60 split or close to works best to absorb fast then eat a solid meal after about an hour

None of the carbs should come from fruit juices. Fructose is absolutely horrible for post-workout.

Bump on that!! Stay away from fructose p/w. It has no effect on insulin, it does not replenish muscle glycogen it replenishes liver glycogen, excess will be turned in to fat.
 
Ok guys, we need to clarify the issue with fructose. Yes it is horribel as a post workout carb, but not because it will not replenish muscle glycogen. It will do so AFTER liver glycogen has been replenished. However any sugar the automatically goes to the liver first will tend to slow down metabolism. Taking in fructose will slow down metabolism, if taking in large quantities, and indirectely cause body fat gain over time. Bodybuilders should avoid it.
 
That is true about Fruit juices...I stay away from them as well in my diet, so I agree with above. I was just printing the diet from Charles Poliquin. You can see his article on Testosterone!

Creatine and glutamine are great things to add in pw diets.
 
Where do I get dextrose? I've tried getting post-workout carbs from 2 slices of wheat bread.
 
I had it written down and now I can't remember what page. I am pretty sure it came from the following, but not sure which article:

http://www.t-mag.com/nation_previous/03.html

It is in one of the articles and I believe it is an interview with either Charles Poliquin or the Swolecat. These are generally the only articles I read, so it is somewhere in there in one of the back issues. I will keep looking.

www.supplementdirect.com for the dextrose.

and synpax... whole wheat bread is a low gi carb and is the exact opposite of what you want. If any type of bread post workout, you'd want white bread. But even better get some dextrose. It's cheap, effective, and it comes in bulk. You can also check the ingredients of some candies. For example, shock tarts contain dextrose along with tons of other popular candy

lol... why not just divide BW by 4?
 
You can get dextrose at any wine/beer kit store. It's like $1 a lb for the stuff...super cheap.

I use it in my post workout shakes. I'm sure it's good for you and everything, but I just like the taste. lol
 
From back at a time when dextrose was considered some sort of magic food. It's just sugar.
 
It will not hurt you and will only benefit you. Post workout your glycogen and amino acid levels are depleted. You want to replenish them as fast as possible with an easy digesting protein source and carbohydrate source.

I personally like the carbohydrate powder waxy maize much more then dextrose. Waxy maize has a high molecular weight which causes a 'shuttling effect' in the body. It will help shuttle the amino acids from the protein source into your muscle cells after your workout. It is also sugar free.
