Bananas bad to eat after a workout?

[terracotta]

There's also 6 grams of starches in that banana. The more ripe the banana, the more of that starch that is converted to glucose. Anyways, your body can break the starch down into glucose itself.

The sucrose is half glucose.

Total carbs - fiber - 1/2 sucrose - fructose = 27-3-1.5-6 = 27-11 = 16g carbs left.

However, we all agree (I think) that more than 16 g carbs is neccessary.

[svillasenor]

5 grams is fructose. So the remainer of the digestible carbs [minus the fructose in the sucrose] can replenish muscle glycogen. Is that really hard to understand?

thats what i mean your repeating what i am saying. i never said it not a nutritious food. but in order to fully replenish your muscles after a workout you need more than what a banana will give u. assuming you actually work out hard.

[Dr. Horse]

Why does everyone think that human metabolic processes are a one way street? Energy stores are fluid/dynamic in the human body. What do you think would happen if fructose was your only source of carbohydrates? Do you think that you would completely and permanently deplete glycogen in skeletal muscle?

[in10city]

so much broscience and brologic in this damn thread its pathetic. can someone please inform the man that your muscles can not convert fructose (sugar from fruits) into glycogen for energy use. So while a banana is nutritious, it will only supply glycogen for your liver and not your muscles.

False.

WOOOOOOWWWWWW 5gs. Are you serious. Come on now. That wouldnt even replenish one forearm muscle.

False.

False. Correcting your misinformation.

[Definitelynotme]

i have a banana after every workout

[svillasenor]

False.

Okay, I clearly do not know what I am talking about then. See it that I am graduating with a nutrition degree, already got into graduate school for it, and if you look at my progress pictures clearly gaining 60 pounds in one school semester has not validity to what I know. Right on brosky right on.

He's right. You're wrong.

And if you want to compare education and degrees, I'm game.

So you mean to tell me that zero of the carbs in a banana will replenish muscle glycogen? The education system has failed you then.

i didnt say that. you are correct in that i may have stated it wrong. But only about 10 to 12g depending size of the fruit will go to muscles. And Yes, it is nutritious. All i am saying is that you need more than just one. is that clearer?

[djansen]

I dont eat regular bananas after a workout anymore, frozen bananas are WAY better.

[joco1214]

ditto.

I think if your gonna spike your insulin anytime throughout the day, post workout would be best

Any mixed meal will illicit an insulin response. Certain amino and fatty acids can augment insulin levels.

You want that actually, after a heavy workout, your glycogen store are depleted and muscle needs quick supply of refills from carbs.

A 1 - 2 hour weight training workout, in a fed state, is not going to deplete glycogen. Rapid glycogen replenishment is not necessary.

sucrose is not ideal after a work out, but some sugars such as the one is Jam, I forgot what its called can be good post workout

In a trial by Casey, et al., there was no significant difference in muscle glycogen synthesis following glucose versus sucrose ingestion.

As long as you get into carbs and protein, you will be fine. I just do not reccomend taking in any fats after a workout. Some guys taking slow digesting carsb and some (like me) take in fast-digesting. I use 60gm WAXIMAIZE and 20 gm whey protein right after a workout and then 1 cup of oats and 20 gm whey 20 min later then 2 cups brown rice and 4 oz. chicken 1.5 hours later. This seems to work great for me. good luck

Dietary fat ingestion post-workout has a negligible effect on both muscle protein synthesis and glycogen re-synthesis

Originally, you stated that bananas will only re-fill liver glycogen. This is false, as in10city noted.

Obfuscate much?

[LSM777]

banana(fructose)+milk(lactose)+whey protein= Perfect mixture of sloow/fast digesting, insulin spiking nutrients!

So after this shake, how long do you wait to eat again? I had heard that after your post workout shake, you can/should eat again relatively quickly...1 hr? Or does the addition of the of the milk(slow digesting) eliminate the need to eat again ryt away?

[LSM777]

thats what i mean your repeating what i am saying. i never said it not a nutritious food. but in order to fully replenish your muscles after a workout you need more than what a banana will give u. assuming you actually work out hard.

So whats your post workout suggestion then? Someone suggested milk/banana/whey which seems to make sense? Please advise..TIA

[Derk4397]

So I eat the banana after I am done working out to spike my insulin levels, then I eat more food soon after yes?????

Is that what you guys are saying? Because this thread makes my head spin.

I heard they are not right to eat after a workout because they have sugar in them and your insulin levels are spiked at that time. Is this right?

Okay - this is the deal about simple sugars and PWO.

PWO, you need fast-acting carbs. Now, simple sugars (bananas, apples, oranges, etc.) I very high in FRUCTOSE, which is the sugar produced by the plant (obviously). The thing with fructose, is that it refuels the liver - NOT the muscles. To optimize muscle growth after a workout, it's best to eat fat-delivering carbs with the highest GI possible, which would be carrot juice, grape juice, rye bread, dextrose, maltose, white rice, white bread, etc.

On the GI table, a banana is barely close to 50. (70 being the point where the food is considered "high GI") I used to be a banana-post-workout, but it's been known that fructose is something that isn't the best to be consumed PWO, because it does very little for your muscles. A banana is okay to have in ADDITION to other carbs PWO, but it should not be your main source of carbohydrates after a long training session.

Btw, in answer to your original question, you DO want the insulin spike post-workout. This is what causes muscle growth...duh. The only time you don't want a major insulin spike is throughout the rest of the day, which is why you consume slow-digesting carbs such as quinoa, oats, brown rice, etc.

[TheWaffleIron]

PWO, you need fast-acting carbs.

No. Unless the trainee is working to complete glycogen depletion an overnight fasted state, there is no need for "fast-digesting" carbohydrates.

Not all of the fruit in sugars is fructose - there's additional glucose and sucrose (albeit, in small amounts), as well.

Fructose is mainly absorbed through liver.

The glycemic index is tested on unmixed foods, in an overnight fasted state. The conditions are hardly relevant to the manner in which foods are typically consumed.

Btw, in answer to your original question, you DO want the insulin spike post-workout. This is what causes muscle growth...duh.

The effects of insulin on muscle protein synthesis are maximized at slightly above normal levels. A massive insulin "spike" is not going to further augment protein synthesis.

Branched-chain amino acids as fuels and anabolic signals in human muscle.

Rennie MJ, Boh? J, Smith K, Wackerhage H, Greenhaff P.

Medical Sciences, University of Aberdeen, Aberdeen AB24 3FX, UK. michael.rennie@nottingham.ac.uk

During exercise, there is an increase in amino acid (AA) oxidation accompanied by a depression in whole-body protein synthesis and an increase in protein breakdown. Leucine oxidation increases in proportion to energy expenditure, but the total contribution of BCAA to fuel provision during exercise is minor and insufficient to increase dietary protein requirements. When investigating the effects of AA on the control of muscle protein synthesis (MPS), we showed that increased availability of mixed AAs caused a rise in human MPS to about the same extent as complete meals. Leucine alone (and to some extent other essential, but not nonessential, AAs) can stimulate MPS for a short period, suggesting that leucine acts as a signal as well as a substrate. MPS stimulation by infused AAs shows tachyphylaxis, returning to basal rates after 2 h, possibly explaining why chronically elevated leucine delivery does not elevate MPS clinically. Increased availability of essential amino acids (EAAs) results in dose-related responses of MPS, but, in elderly subjects, there is blunted sensitivity and responsiveness associated with decreased total RNA and mRNA for signaling proteins and signaling activity. Increases of MPS due to EAAs are associated with elevation of signaling activity in the mammalian target of rapamycin (mTOR)/p70 ribo****l subunit S6 kinase eukaryotic initiation factor 4 binding protein 1 pathway, without requiring rises of plasma insulin availability above 10 microU/mL. However, at insulin of <5 microU/mL, AAs appear to stimulate MPS without increasing mTOR signaling. Further increasing availability of insulin to postprandial values increases signaling activity, but has no further effect on MPS.

A mixed meal (including any type of carbohydrate) will illicit an insulin response.

Of any quantity? Or does it take a certain amount to start the process?

To the OP:

The answer to your question is a big fat NO!

They are great to eat after workout and go great with chocolate protien shakes

[Simmo0508]

No. Again, a 1 - 2 hour weight training workout is not going to deplete glycogen, thus rapid glycogen replenishment is not an issue

It will partially deplete gylcogen stores. It will typically not deplete glycogen completely.

If you truly believe a big 1-2hr workout doesn't do anything to glycogen, then you must train like a little baby girl. Seeing as though we're on a bodybuilding site, most people train pretty hard during their workouts and want better than a "that'll do" attitude and thus more than those type of results. They want the best they can possibly achieve.

Now when bodybuilders train day in day out, weights, cardio, everything, they need to keep their energy up at all times to the best of their ability. After they beat the **** out of themselves one day, they have to back up and do it all over again the next day with equal or higher intensity for another muscle group etc.

If one's glycogen isn't that full, many will struggle to perform at their best level. Thus why many guys use sugar intra and post-workout, on top of their already high complex carb intake. It's to restore and replenish those partially depleted glycogen stores, to a higher point. The point is to avoid completely depleted glycogen ever occuring. It's like driving a car. You don't get petrol when you run out and are stranded on the side of the road, you get petrol when you see you're tank almost empty and "refill" so to speak etc.

Anywho, Fitlover was correct for the most part. Well said.


As for the topic of bananas, i personally don't eat them after training. I just have my whey and that's it, then carbs in my food meal at home 1hr later. A lot of old school bodybuilders used to loveee their bananas after training though. You'd see em do that sort of thing all the time. There's nothing wrong with bananas with your shake for instance. The potassium it provides is important also obviously.

I sometimes use a Gatorade or a BCAA drink with sugar on like a leg day or something when i feel like ****, but i'm fine without it generally. I use a glucose product called Glucodin sparingly, but not consistently.

Thank you for again unnecessarily taking a shot at my credibility under the false assumption that I don't lift. This is the second time you've done this, at least.

That said, this was my original quote,

No. Again, a 1 - 2 hour weight training workout is not going to deplete glycogen, thus rapid glycogen replenishment is not an issue.

I clearly stated that glycogen would not be "depleted" - or completely exhausted - in fed state.

I never stated that weight training would have no effect on glycogen levels. It does, just not to the effect that would require "fast-digesting" carbohydrates to rapidly replenish tissue glycogen stores.

Seeing as though we're on a bodybuilding site, most people train pretty hard during their workouts and want better than a "that'll do" attitude and thus more than those type of results. They want the best they can possibly achieve.

And consuming slower digesting carbohydrates is going to yield inferior "gainz?"

Now when bodybuilders train day in day out, weights, cardio, everything, they need to keep their energy up at all times to the best of their ability. After they beat the **** out of themselves one day, they have to back up and do it all over again the next day with equal or higher intensity for another muscle group etc.

Any source of carbohydrates will suffice.

If one's glycogen isn't that full, many will struggle to perform at their best level. Thus why many guys use sugar intra and post-workout, on top of their already high complex carb intake. It's to restore and replenish those partially depleted glycogen stores, to a higher point.

"Slower-digesting," complex carbohydrates can replenish glycogen, as well.

The point is to avoid completely depleted glycogen ever occuring. It's like driving a car. You don't get petrol when you run out and are stranded on the side of the road, you get petrol when you see you're tank almost empty and "refill" so to speak etc.

For the third time (at least), a 1 - 2 hour weight training workout, in a fed state, is not going to completely deplete muscle glycogen.

Anywho, Fitlover was correct for the most part. Well said.

No, she wasn't.

I eat banana right after my workout , and feel good. If i drink just protein shake its not feel right, i feel kinda down.
