Post Workout Meal Nutrition -
what to eat after a workout

The post workout meal (the meal you eat after a workout) is probably the most important meal of the day for anyone who is into nutrition and fitness. However, in a lot of cases this importance also leads to confusion. Maybe it's because of the many ready-made shakes available. Maybe it's the trouble with fitting it in with the rest of your diet. Maybe it's just generally not knowing whether you should even eat anything after you've worked out. Whatever it is, something about it confuses people.

The truth is, once you understand the basics of what nutrients your body needs and doesn't need after your workout, and what the best sources are to get this nutrition from, the post workout meal will probably become the most simple and quick meal of your day. And, luckily for you, I just so happen to be explaining all of this information in this very article.

What you should and should NOT eat after a workout.

Simply put, aside from water (which you should already know you need) your post workout meal needs to contain 2 things, and it needs to not contain 1. You should be eating protein and carbs. You should NOT be eating fat. More on the protein and carbs you need a little later. First, let's start with a quick explanation of why you shouldn't eat fat after a workout.

Many times throughout this website I explain why fat is NOT a bad thing (when it's the "good" fat) and why it is an important part of everyone's diet. However, there just happens to be a certain time when fat (good or bad) wouldn't be good to eat. This of course is in the post workout meal. Simply put, fat slows down digestion. In this case, it would be slowing down the digestion of protein and carbs. This, as you're about to find out, is the exact opposite of what you want to happen.

At this point you should really have just 3 questions about your post workout meal:

1 - How soon should I eat it?
2 - How much protein and how many carbs should I eat?
3 - What foods should the protein and carbs be coming from?

Hey, what a coincidence, here comes the answers to all of those questions...

How long after my workout should I eat my post workout meal?

Soon... really soon. As soon as you can. I don't mean put-down-the-dumbbells-and-start-eating. It doesn't need to be quite that soon. However, there is this "window of time" that exists after your workout during which it would be the most beneficial for your body to receive it's post workout nutrition. Typically you'd want to try to get this meal into your body within 1 hour. If possible, within 30 minutes would be even better. I personally have my post workout meal about 5-10 minutes after my workout. What's that you say? How can I do it so fast if I'm at the gym? Don't worry, more on that later.

Post Workout Protein

Now that you know that time is of the essence when it comes to your post workout meal, this part is going to make a whole lot of sense. See, eating this meal soon after a workout is important, but just because you are putting the food into your body quickly doesn't actually mean the food is being digested and used by your body equally as quick. While egg whites, chicken and tuna fish are fine sources of protein that I personally eat daily, they aren't the ideal type of protein for the meal after your workout.

These foods are whole foods, and the protein in whole foods digest pretty slowly. You may have eaten a high protein food in your post workout meal, but by the time the protein is digested and finally ready to be used by your body, a whole lot of time would have passed. This is why the ideal source of protein to eat after your workout is a whey protein powder mixed with some type of liquid thus creating a whey protein shake.

A whey protein shake will be digested by your body much quicker than a whole food because it will be a liquid. And, not to mention, whey protein is the fastest digesting protein there is. This is what makes whey protein pretty much the official choice of most people as their post workout meal protein source. As for how much, try to consume between 0.15-0.25 grams of protein per pound of your body weight (so a 175lb person would shoot for between 26-43 grams at this time).

As for the whey protein powder itself, I personally use Designer Whey Protein Powder.

Post Workout Carbs

Yeah yeah yeah. "Carbs are bad! Carbs are the devil! I am scared to death of carbs! Get them away from me!!" Settle down. First of all, they aren't so bad. Secondly, after your workout they are actually an extremely important part of your post workout nutrition. Carbs will be used by your body to restore muscle glycogen. If your post workout meal doesn't contain carbs, your body may actually instead break down muscle tissue for this same purpose. That would be a bad thing. Carbs also create an insulin spike which helps to move nutrients into your muscle tissue quicker.

So, now that you know you need them after a workout, what kind do you need? Well, you know all about good carbs and bad carbs by now, right? Funny enough, this is actually the only time when "good carbs" and "bad carbs" switch roles. This doesn't mean start eating cookies, this just means that typical good carbs (whole wheat bread, brown rice, etc) contain fiber, and fiber slows down their digestion. This is actually what makes them "good" any other time of the day. But by now you know the post workout meal is all about speed. And when it comes to speed, simple carbs beat complex carbs.

A food like a baked potato is an okay choice for a carb source after a workout. However, just like protein, whole foods in general aren't really the most ideal choice at this time. This is where a little something called dextrose comes in. Dextrose is not a supplement... it's actually just a type of sugar. I know, I'm basically saying you should eat sugar. While that would be insane any other time of the day, your post workout meal is the one exception.

Along with whey protein, dextrose has also become almost an official choice for a post workout carb. Most people should look to consume somewhere between 0.25-0.4 grams of carbs per pound of their body weight from dextrose (a 175lb person would shoot for between 40-70 grams). I think most people should stick more towards the lower/middle end of their range rather than higher end. As far as dextrose goes, I personally use NOW Foods Dextrose.

My Post Workout Meal

To finish this article up, here is what I do. Before I leave for the gym, I put everything I need inside of a shaker bottle. A shaker bottle is just a plastic cup with a cover and some type of "blending" piece inside. You just put something in it, add water, and shake it for about 5-10 seconds. It is simple and extremely convenient for your post workout meal. I put in the whey protein powder, dextrose, 5 grams of L-Glutamine (more about L-Glutamine), and 5 grams of Creatine (more about Creatine) and take a bottle of water with me.

After my workout I get into my car, open the shaker bottle, pour in the water, shake for 5-10 seconds and drink on the ride home. The whole process takes less than a minute and the whole "meal" is finished in a matter of minutes if I take my time. There you have it... quick, easy, convenient and contains the best sources of everything my body requires post workout.

What I use:
Designer Whey Protein Powder
NOW Foods Dextrose
Optimum Nutrition L-Glutamine
Optimum Nutrition's Micronized Creatine Powder
Shaker Bottle
Water

Je zult honderden van die artiekeltjes lezen op het net die claimen een patent op de waarheid te hebben. Nu wil ik neit zeggen dat ik de absolute waarheid bezit maar hij is inder geval onderbouwd. Wil je nogmaals vewijzen naar mijn eerdere posts.

ja ik weet het nu ook niet meer,ik ga gewoon wat minder dextrose nemen en halfuurtje onderweg naar huis en dan een goede maaltijd bruine rijst, kip en groenten zal wel goed zijn zeker?

edit : maar ik denk dat dextrose niet echt goed is wanneer ik na de training cardio doe voor vetverlies of is dit minimaal ?
 
Laat die dextrose nu man. Denk gewoon eens diep na

Welkom in de wereld die trainen heet. Daar waar iedereen er verstand van heeft maar tegelijkertijd elkaar tegenspreekt :D

Maak je niet druk! Het gaat je in ieder geval geen kg's schelen of je het nu wel of niet doet.
 
Probeer een tijdje zonder en kijk wat er gebeurt.
 
Naast dat de window of oppertunity debateerbaar is, is het feit dat je dextrose PWO nodig hebt (zoals ik boven al eerder vermeld heb) wellicht helemaal niet nodig om insuline levels te stimuleren tot het punt wat nodig is om adequaat proteine synthese te stimuleren.

De receptoren zijn aantoonbaar gevoeliger na de training, wat ook logisch is. Die gevoeligheid zie je ook bij bepaalde dieten. Heb je dan die insuline nodig? Ja. Heb je dan persee dextrose nodig? Nee.
Ik denk dat een constanter insuline niveau zoals je die bereikt met complexe koolhydraten je meer opleverd dan een korte piek in de vorm van dextrose.

Daarnaast heeft onderzoek ook aangetoont dat het zelfs helemaal niet uitmaakt welke vorm van koolhydraten je binnen krijgt om na je training je glycogeen voorraden aan te vullen zo lang je maar voldoende Kh's binnen krijgt gedurende de dag (http://www.ncbi.nlm.nih.gov/pubmed/9127682)

Weet niet of het aan mij ligt maar ik word er steeds sceptischer over.

Dit brengt ons weer bij het punt hoe zinvol een korte insuline piek is na de training dmv het nuttigen van dextrose. Waarschijnlijk nihil. Hiermee is de circel weer rond. dus complexe koolhydraten (maar ook van de andere macro nutriënten) gedurende de dag geven een constant insuline niveau waardoor nutriënten constant voor de cel beschikbaar blijven.
