Carbs and also the Glycemic Index space two of the many misunderstood topics in fitness. Here’s exactly how to fine-tune your strategy at one of the most vital junctures: after your workout.

You are watching: Good carbs to eat after workout


After the workout is the various other time to take it in an easy carbs: this is vital because that starts the whole recovery/muscle expansion process. Complying with a hard workout, her body is severely depleted of glycogen and also glucose.

During the workout hard working muscles use glucose (usable energy) and also glycogen (stored energy) because that energy. Together such, over there is a point at i beg your pardon blood glucose level (available energy) and also glycogen levels (stored energy) get so short that extreme exercise can"t continue. There just isn"t enough obtainable energy for her muscles to use.

So what happens is the the hormone cortisol is secreted, this is your body"s "stress" hormone and it has really catabolic effects. What cortisol walk is eat up muscle organization for protein and also convert it right into glucose. A process called gluconeogenesis ensues, creating glucose from this amino mountain in the liver. The net an outcome is a loss of muscle tissue.

The post-workout shake avoids this. It likewise allows insulin to be released, this is, as most of girlfriend know, one of several anabolic hormone in the human body (if you space a organic trainer especially, you desire to maximize the release of all her body"s anabolic hormones through all obtainable methods).

So, whey protein is your ideal protein resource at this time since it is soaked up quickly, what is the finest carbohydrate source? Well, we desire a high glycemic carbohydrate source. This term refers to carbs that are high top top the glycemic index (70 and over rates together high).

The glycemic index is a measure of how quickly a food raises blood sugar and hence insulin levels. Normally, the is ideal to eat reduced glycemic foods items so as no to begin an insulin spike (55 and also under rates as low). Yet post-workout, the precise opposite is true.

It is crucial to gain the carbs (and protein) to the muscle cells as quick as possible. As well, the elevated insulin levels will assist to drive nutrients right into the muscle cells. And again, high-glycemic carbs are finest for this purpose.

Simple Carbohydrates

Simple carbs room naturally existing as simple sugars, arising in greatly fruits and milk, and also some other foods. The two main varieties of sugars are:

Monosaccharides—consisting that a solitary sugar molecule.Disaccharides—consisting the a double sugar molecule.

Listed below are some common sugars:


Fructose—fruit sugar. You could think this would certainly be a an excellent source, but the glycemic table of contents is only 11 because that a 25 gram portion. This way then that it is not digested quickly and does not raise insulin level to any great degree. What this method is the fruit sources are not a good source of carbs for the post-workout drink.

Dextrose—also known as glucose. You can buy this as a powder from various various sources. It has a rating of 96 because that a 50 gram portion. This is among the much more common sugars provided in short article workout shakes. Dextrose is a good choice, however, part users find that they have a pour out over effect that outcomes in fat gain, so the makes much more of one individual selection as girlfriend would have to test it and assess the results.


Sucrose—this is common table sugar. It"s comprised of one molecule that glucose and also one molecule the fructose. It has actually a rating of 60 for a 25 gram portion.

Lactose—milk sugar. This has actually a rating of just 48 for a 25 gram portion.

So together you have the right to see, various other than dextrose, most of these sources are not right as part of the post workout shake.


However, prior to maltodextrin deserve to be utilized, it must very first pass through the liver for the bonds between the glucose molecule to be damaged down. So the rate at which that is offered for glycogen replenishment is slow than through dextrose. However, due to the fact that it is metabolized slower, there will not be as fast of a autumn of insulin and blood sugar levels as with dextrose. There shows up to be no potential for fat acquire from the use of maltodextrin.

Two good Choices

So here we have actually two an excellent choices: dextrose and maltodextrin. Girlfriend can try each one and see i beg your pardon one seems to occupational better, however what has come to be a popular technique is to incorporate dextrose with maltodextrin, in a 50/50 combination. This renders sense since consumption of dextrose by itself have the right to be worse for several reasons.

First, studies present that gastric emptying (the procedure of digesting and also emptying food the end of the stomach) is slowed fairly a bit when the concentration of liquified particles in a systems (osmolarity) is raised.

Dextrose, being a solitary sugar molecule, will certainly raise a solution"s osmolarity, this in impact slows gastric emptying. Combine dextrose v a glucose polymer (a processed type of complex carbohydrates, in this instance maltodextrin) allows much more even digestion, v no slowing taking place. So this mix will optimize glycogen replenishment, hydration and performance.

I see this together still a an excellent choice for short article workout carbs, although rather outdated, considering the brand-new advancements as we will certainly look at next.

New Advancements

Waxy Maize

This is the newest carbohydrate product come hit the market. Waxy maize comes from corn starch and also is absorbed really quickly: most carbohydrates space passed to the minister tract and also broken down for digestion; waxy maize passes through the gastric lining there is no the require for gastric emptying various other carbs require.

It likewise will permit other supplements, choose creatine, to be absorbed an ext rapidly - Some well known formulas have this mix while countless others carry out not; the rather contain waxy maize by itself.

My conclusion ~ above this type of carbohydrate is that it"s good as part of a volumizing stack, or as a creatine loading product, to be taken during the work or even pre workout. While over there does it seems to be ~ to be a usual perception the waxy maize go not cause an insulin spike, my research study for this short article indicate that it walk in fact reason an insulin spike.

As a post-workout source of carbs, this does it seems ~ to it is in the carbohydrate of selection right now. Take your time in picking a product the this type, together the sector is now flooded v them, you have actually recovery formulas, you have actually waxy maize formulas combining different straightforward carb sources with waxy maize, which can potentially reason a better insulin response, you have some that room meant to be mixed with protein, some that aren"t, some that mix poorly and clump all up and also some that mix better.

I would quite make my very own post-workout drink quite than to buy a "recovery" drink, therefore I would certainly pick one that mixes well, and also that can be combined with protein. Let"s not forget how vital protein is to the write-up workout "window that opportunity", and that might mix with every little thing else I want to toss in.


Carb to Protein Ratio

Now, what then room the optimal parts to take in concerning your protein/carbohydrate shake? Weight and also training intensity are two factors that pat a role here. Many sources suggest .25 (cutting) come .50 (mass gaining) per lb of lean body mass.

Protein need to be in a proportion of 2 come 1, for this reason if you have a skinny body mass of 170 lb, this would median 42 grams of carbs and also 21 grams that protein if you are cutting, and 85 grams of carbs and also 43 grams that protein if you are in a mass obtaining cycle. This must be ingested within 30 minutes of training, and also you should have a good meal within one hour of your shake.
