Exercise & Sugar: When Sugar Can Be a Good Thing

[@theanatomylab]

Something else to consider when ingesting simple sugars (sucrose) after exercise is that many athletes will also add a complex carbohydrate within the next hour after ingesting the sugar in order to help minimize any rapid decline in blood glucose levels, creating a more sustained release after that initial “spike” of glucose and further bolstering the replenishment of glycogen. Hope it was a helpful and fun video! Thanks for watching!

[@Darkregen9545]

Thanks for covering this. Hopefully the scientific community will express this information everywhere so the US military will adapt this as a part of their diet for recruits, because they deny recruits from consuming anything with sugar at their chow halls during basic training, and tell them sugar is the main culprit of cancer, and not good for you (Junk food) I often felt a fall of long term energy being deprived of fructose and glucose and sugar. I don't remember much fruits from my basic training in 2018.

Can you make a video about “intromyoceullar lipids” or whatever it’s called lol and their impact on insulin not being effective in moving glucose to be stored as glycogen in cases of people with fat in their muscle cells. I’ve heard that is part of diabetes and the sugar issue but I could be wrong. I’m asking this in relation to the people who are in the “high fat dieting” camp and their health outcomes vs their claims.

why do our cells need to be told when to take in sugar. Why not take in sugar when needed.

00:03 Exercise affects the body's ability to process and store sugars. 02:12 Glucose is the main form of sugar that our body utilizes. 04:11 The glycemic index measures how quickly carbohydrate-containing foods are broken down and absorbed into the bloodstream. 06:12 Exercise increases glycogen storage capacity. 08:09 Regular exercise increases glycogen levels, allowing longer and higher intensity performance. 10:23 Exercise sensitizes muscle fibers to insulin, reducing the need for insulin to bring in glucose. 12:26 Adding protein with carbohydrates enhances glycogen replenishment and insulin response. 14:31 Sucrose is considered empty calories, lacking fiber, vitamins, and minerals. 16:41 Excess glucose is converted to and stored as fat, which can contribute to weight gain and health concerns.

Hey, can you tell me if I got this correct? Exercising means we can eat a little more than resting people because we got more glycogen capacity. And more glycogen capacity means we can eat as much as we want as long as glycogen doesn't get filled to the brim. Because if it's filled, it will go under weight gain. Right?

I've been a type 1 diabetic for 24 years and a powerlifter/olympic weightlifter for maybe 6 years and I've been preaching about the glycogen buffer to my fellow beets and anyone else who'll listen for most of of those. Similarly, like you touched on, I find a big thing most regular people/non diabetics miss or don't take notice of is intra-workout carbs- top powerlifters and strongmen will drink honey in the gym, and for good reason- insulin and glycogen have a near direct and near immediate effect on your gym sesh. Dextrose is the fastest acting carb and they come in 4g measurable tabs and they don't taste good (which is a huge plus cause you wont eat them outside of the gym and they don't come with other processed ingredients, fats or junk like almost all protein bars do), so I usually recommend dextrose tabs and particularly if you know you're going to be working out more than 45 minutes.

[@C0d0ps]

Minuses: Processed ingredients do not matter if consumed in a small volume. Fake sugar will in the long term lead to more weight loss. Imagine never drinking sugar soda again, now imagine that but replaced with diet soda. The affects are largely the same. You lose weight. - Pluses: As an mma practioner I frequently consume bananas and chocolate (protein bars) to keep my glycogen peaked. - Background: I am currently training around 15h/week at 90 min per session. Some days have 2x/day workouts. - Fast absorbing fruits and candy: Banana are absorbed after roughly 90 min I’ve heard, and besides on Sunday, I only have 5 minute to eat between 2x/day sessions.

As a fellow Type 1 diabetic (27 years), and a bodybuilder, I would LOVE to hear more on this topic. Please, continue.

[@C0d0ps]

As a marathon runner it is important to remember how long it takes to digest different foods. - If you like pasta then I would eat it around morning and run towards evening. Or eat it late at night and run during morning. I would imagine a rough timeline is 6h for pasta to digest. - Bananas and protein shakes are generally absorbed in 90 minutes. Steaks 2-3h depending on how protein and fats they have. I’ve heard we absorb roughly 40g protein per hour. High fat foods like avocados should also be absorbed within 2h.

Neat. I'd like to have a better term than "exercise" for what causes muscle sensitivity to insulin to increase. Like strength training vs zone 2 cardio vs sprinting. Also, most of the glucose in veggies is not digestible because it's part of the plant cell walls which we cannot breakdown. So that's a little bit of a poorly worded way to compare veggie carbs and straight table sugar. I'd also like to learn more about the ways the body replenishes glycogen when glucose is not consumed post workout. Surely there are costs and benefits. I'm also interested in learning more about the role of mitochondria and how they can become more efficient at glucose and or fat use for energy. You also didn't mention the dangers of glucose consumption in terms of the liver becoming fatty over time. That seems like a quick note worth mentioning. Cool video. Looking forward to more.

How is the body running on fat?

[@Gregorymusicman]

I was curious about your statement regarding fat in the video. You said essentially that fat doesn’t need to be converted and it gave the impression that ‘fat makes you fat’ however I thought that bile helped to break down fat. Also I learned through trying the keto and carnivore diets that fat is essential for certain organs like the brain to function properly. I found that increasing my fat and protein and lowering my carb intake caused me to lose weight and reduce fat in my body without significantly increasing exercise, I also thought that we can’t really remove adipose tissue from our bodies though our diets but we can reduce the size of those cells as that release the stored ‘energy’ and retained fluids when our body uses it for energy instead of the glycogen. I would be interested for you guys to do more videos into these subjects. Lies my doctor told me by dr ken berry was helpful to me understanding some of this.

When fasting and blood sugar goes too low glucagon, adrenaline, and cortisol rise to replenish blood sugar squeezing glycogen from the liver. Adrenaline and cortisol also release fat into the blood creating insulin resistance, slowing the absorption of glucose for survival purposes. All these actions impede on the thyroid system and effectively slow metabolism. Main benefits I think are giving the digestion a break from crappy food. But you could also just eat easy to digest food

[@thediamondarmking6545]

@@aspiresk8boarding Hi, great reply, but I don’t think Insulin resistance come from fasting. I think it actually comes from constant consumption of carbs, especially refined. Carbs raises the most insulin, then protein which is not as much and the fats which almost do not raise . Too much insulin causes insulin resistance. Keep in mind that what I’m saying is not 100% since science is not simple. I hope you have a great day:)

@@thediamondarmking6545 High insulin is a symptom of insulin resistance. But regular insulin spikes don’t like “de sensitize” insulin receptors.

High cortisol person or obese have high amounts of fat in the blood slowing glucose uptake. Fasting or low carb diets only hide insulin resistance by avoiding insulin spikes.

10:54 folks, if you plan on running please don't do it with these people are doing and hop up&down while you Try to move forward, lean forward a tiny bit and learn how to use your glutes to propel you forward, so that you don't do damage to your ankles knees hips and spine because although everybody thinks they can run, there is an actual skill to it and that very evident, pronounced hopping will lead to injuries

[@adarshjoshi1434]

As a regular gym goer , I experience that after I consume my dinner (normal Indian dinner ), I feel fatigue so much so that I don't feel like doing anything for the next 1 to 1:30 hr. Can you please explain how and why this happens and what can I do to solve this problem?

[@natiw2000]

me too

[@captlanc]

Too much carbs. I assume your dinner is carb centric like rice or naan and such? I'm no expert but I have the same problem. What I do is I add more meat/other protein and vegetables (not carby ones) and greatly reduce my intake of rice and bread etc and I don't have the same problem anymore. Sometimes I have a cheat meal with loads of rice and the same overwhelming fatigue comes back to remind me how bad I am with carbs lol.

[@IkramulTanvir]

Normal rice has high level of glucose spike , that's why u feel tired , on the other hand, brown rice has low level glucose spike , so u can't easily fatigue for no way

Johnathan a well presented piece, nice images and clearly explained. I have read that the intestines can in-fact convert up to 30g/hr of fructose to glucose and thereby give some buffer to the liver. I dont have that source at my fingertips at the present but have you read anything similar? thks 👍

Wow! Thank you so much for explaining so many things. This one video answered a lot of my questions. 😅 Actually, just yesterday I was so frustrated with my sweet cravings after exercising and was asking God why did He create it when it’s so bad. Guess He answered my question through your video. 😂😂😂😂 I do exercise for a few hours in a day but also have a sweet tooth. Many scared me saying it’s not good and I was feeling so bad thinking I can never eat anything sweet. But I’m super happy to hear it from you that it’s ok to have it in the 1-2 hour window. You just made one person in this world way too happy. I’m literally jumping with joy. Of course I’ll remember the complex carb thing you mentioned in your comment as well. 😂😂😂😂 Also, I was wondering about how the stamina increases in individuals and you answered that question as well. You are super awesome and you just got a diehard fan ❤❤❤❤

[@EnderGirle]

I’ve always wondered, as a post exercise shake, is it better a protein shake or an amino acid shake? I know amino acids are protein building blocks, but I’ve noticed that taking protein makes your muscles grow, but not necessarily your strength, whereas amino acids take longer to grow muscle but you tend to get stronger. So… I wonder what’s the biochemical difference between taking either. I take amino acids and feel like the aid quite well with muscle recovery

[@SlardaTorakka]

This really changes things.. o,o For few years now, I've thought that carbs are bad mostly for two reasons; Becouse it raises your insulin levels and becouse your body wont use stored fat as energy source as long as it has carbs available.. If exercise makes it so that you don't need insulin, the first bad thing isn't really a thing, and the second really matters to only those who are over weight.. o,o Thank for an awesome video!!

Hey Jonathan, I am seriously addicted to sugar. I have been all of my life. I started experiencing the effects of Hypoglycemia somewhere in my thirties. Somewhere in my life i learned about glucotabs and have carried them on my person or in my vehicles and kept them in my home for years. I just turned 75. In the last few months or so, I have noticed when I get out of bed of a morning, I am experiencing the effects of Hypoglycemia. I have taken to having a couple swallows of some sort of sweet soft drink to carry me through until I have some sort of breakfast. Then I am pretty good to go for the day unless I get very active and need a sugar boost. Is hypoglycemia a subject you can base a show on ?

[@aspiresk8boarding]

People call it addiction and have some shame over eating carbs and sugars. The body NEEDS sugars for proper functioning. It’s good to listen to your body and give it what it needs. Studies show eating less than 150g carbs for sedentary people raises HPA axis activity meaning up regulating stress hormones and slowing metabolism. After fasting all night blood sugar dips then cortisol kicks in to raise it back up and wake us up. I think it’s so important to carb up in the AM to refill liver glycogen and suppress the stress response

[@ledgy69]

​@@aspiresk8boardingtable sugar obviously isn't what the body needs its what it wants since it's so sweet and calorie dense, our body wants to bulk up for winter starvation but that ain't prolly coming so it's better to NOT listen to your body by eating donuts and other processed dogshit with seed oils, artificial coloring etc. Eat fruits n berries in large quantities or make it into a smoothie and keep in fridge overnight for a breakfast bomb.

Refined carbs (or any other) isn't addictive, the closest they have gotten is a combination of fat, carbs and flavour enhancers (highly palatable food).

[@LeeSurber]

My own observations as a former elite level athlete and engineering technician..!! I was a very high level wrestler and ate candy bars about 30 min prior to my matches..!! This never failed me..!! Fast forward to my 30's..!! I gave up sugar in favor of sucralose because the medical community said sugar was bad for you..!! At age 42, after years without sugar I start getting joint pain and muscle injuries..!! Fast forward to age 56..!! After 20 years of no sugar,,,, with ever increasing pain and extended healing duration,, I decide to start consuming sugar again...!! I now feel stronger, have nearly no pain, and healing time if I do get injured is almost immediate..!! I shared this with my 86 year old father who still loves bowling....!!!! He said, for the last month he's been eating about 2-3 candy bars a day and is now back to using 15-16 pound balls for the first time in years...!! He told me he feels strong...!! I think this observation, at the very least, indicates sugars competitive and healing properties have not been studied carefully enough..!!

[@camscornerbooks]

This is interesting because I have hypoglycemia and really struggle with intense exercise because I tend to have a blood sugar crash in the middle of an intense session and have to keep diabetic glucose tablets in my workout bag. I also hate eating full meals just before working out so heading it off before exercise is nearly impossible. One thing I want to say though is the use of CGMs by non-diabetics. It really concerns me that it can make them harder to access for diabetics (like ozempic) and make people way too focused on non important health data. The average person who is not diabetic does not need to monitor their blood sugar with a CGM and likely won’t interpret the information correctly and can become unhealthily obsessed. Also remember that nutritionists are NOT the same as dietitians. Dietitians are certified and require specific education. Literally anyone can call themselves a nutritionist.

[@obelixpfeifenreiniger2863]

you are pre diabetic. get a gcm.

[@camscornerbooks]

@@obelixpfeifenreiniger2863How… did you know that?! I saw an endocrinologist and she said I was pre-diabetic. She didn’t mention anything about what I posted on regarding sugar crashes during exercise so how on earth did you know?!?! 😮

[@obelixpfeifenreiniger2863]

i am god damn autistic and smart. but yeah: so, you are excerzising - you need energy. the body ramps up sugar production suring excerzise, it is called "gluco neo genesis" (sugar new making). and you have eaten before, so you have enough sugar already in your blood stream. but the body does not really know how much sugar you have in your blodd stream, it gets its signals from the cells. inside the cells, all your cells, there is a tiny engine. it can run on sugar, amongst a couple of things. so, the muscles are working, the cell wants energy. but it ccant get enough, since you are pre diabetic, and the cell wont let the insulin dock anymore, so the sugar door is closed, or not wide enough. so thats why you cras regardless of eating, thats why you crash harder while excersizing. essentially, doing cardio is harder for you, but you need to do cardio, since you are diabetic. you are better of not eating eat all while excerzising. hh so what are you to do? dont eat fast carbs like wheat, bread, noodles, rice and potatoes, and sweets of course. you can eat till you explode, just dont eat those grain carbs and starch carbs. what also really really helps, but it is very hard to do: dont eat anything from morning to morning, so 24 hours. eat a very herty breakfast after 24 hours - but without carbs!!! do this 24 hour fast twice a week, it will get easier, trust me. my advice would be the fasting thing and dont eat wheat or any grains. now rules for quantity, no rules for excerzise. just start with the grains. dont eat them, period. oh jeah: something really really really important: dont eat ANY seed oil. just dont. here, check out this blog: she is a biochemist and once was prediabetic like you or me. drcate.com/list-of-good-fats-and-oils-versus-bad/ one more thing: just do what i said, start with the grains, dont eat sweets, dont eat seed oil. youll be a changed person in half a year. counting calories is useless, excerzising is good, but youll need energy, but yeah, you cant have any. dont start meds, you can do without. just start with the grains. eat good fats. youll need them. a gcm really really helps with motivation!!! @@camscornerbooks

[@camscornerbooks]

@@obelixpfeifenreiniger2863 wow!! Thanks for the link too!

[@obelixpfeifenreiniger2863]

just to be clear: in reality, you have constant HIGH blood sugar, but you cant access it - so you feel exhausted while having high blood sugar. thats why a gcm is so usefull. thats why you have way more energy after eating almost nothing because of sickness or because you were stressed out.

[@matthewgraham2546]

I learned something important today. Thanks for this one.

[@Visionery1]

That initial opening scene reminds me of the 20+ years when I did press-ups every day, I only started getting tired at just over a 100, I used to count 1-2-3-4-5, 1-2-3-4-5, until I completed around 110. The past 5+ years I've been experiencing excruciating pain in my shoulders, more so on the right, sometimes being woken at night. In a nutshell, all these exercises we do are crazy, simple walking and hiking is all we need. My running up and down the mountain in record time also wasn't a good idea. If we go to the extremes it will come back to haunt us.

[@barrywilliams4866]

you probably have a shoulder impingement, by just doing press ups you'll develop an imbalance, this is why you should do various exercises, so press ups are a "push " movement and a pull up would be a pull movement, you need the balance of both..

[@pnp8849]

We've been following French cooking for quite a while; lots of butter, beef, salt and sugar. With the amount of butter in our cooking we couldn't get enough sugar. Martha Stewart she's 80 and still looks good. She use so much butter and sugar in her cakes it's insane.

[@888jucu]

Unless your are trying to grow a 3rd eye or something I dont believe artificial sweeteners have any benefits as they are just chemicals. Since the voodoo has been put on sugar more manufacturers are filling their products with chemicals, I dont see this as a good trade off

[@loganmedia1142]

Depends on the sweetener. Sucralose and saccharin have a negative impact on gut bacteria. There is evidence that stevia does too. Aspartame and others don't. The main benefit of sweeteners is for people who are otherwise struggling to keep their sugar intake at the level they need. But if you're allergic to artificial sweeteners you'd just have to avoid them.

The answer to your question is yes. The body uses the glycerol bone of fatty acids and some other substrates readily available in your body to replenish glycogen through gluconeogenesis. No ingestion of carbs needed.

[@martiananomaly]

@@Szilvia_Szilvia Wait.. so does that mean when cutting, I should not be consuming any food right after a weight-lifting workout? And if yes, for how long should I avoid it? (Assume that my meal will have carbs)

[@Szilvia_Szilvia]

​@@martiananomalyUnless you're emaciated, your body has enough substrates to function independent of being right after a workout or not. If you're cutting as in bodybuilding, you may risk losing muscle you actually want to keep, if you're in a big deficit for too long time, so unfortunately the answer is, it depends... on the 2nd day of your cut, nothing negative will happen... but if you're at the end of let's say 2nd week and you are well under your needs, you will lose both fat & muscle, even if you're eating carbs. The difference the carbs make is 1) may cause systemic inflammation 2) every 1g holds 4g water, so your scale won't budge easy 3) makes you hungry within a much shorter time than if you were without them. Hope that helps.

So after a cardio workout or strength workout I should have some simple carbs to refill the muscles that were used.i am not a suger person but listening to this I understand now why my coach has me haveing rice krispies or coc pops after my workout to replace used glycogen and get me ready for my workout the following day.

Fantastic explaination. Only video to watch if you wanna know about glucose and its relation to exercise. Thanx!

[@DexterGenmarino]

Thanks for that video! Is there maybe the possibility to cover fat also at some point? Or maybe you could just answer this here. It is really confusing how fat metabolism works. You mention in the video that fat gets stored as fat, but how much of the fat one eats during the day is immediately used for energy utilization? Wouldn't that require a ketosis state? At Andrew Huberman's Podcast, Andy Galpin just briefly mentioned the fact that if you do cardio, during the session, you are utilizing fat (zone 2, aerobic, therefore fat); during resistance training one utilizes primarily glucose (as you mention in the video). But after zone 2, you enhanced your ability for Glucose absorption and after resistance training you enhanced your ability for fat metabolism. This is confusing to me. By which mechanisms does this happen respectively especially for the fats? The brain is fueled only by glucose, so if I only eat meat this fat will have to be broken down somehow into glucose right? But this would contradict the statement to some extent that fat is stored as fat (as you say in the video). Sorry if I'm missing something fundamental here, fat does really confuse me though. Thanks again for this video and also for the rest you do! Much appreciated!

I use to do Spartan(OCR) and Ragnar races. Prior to the race, I would have a clifbar, coffee, and Liquid IV(electrolyte). Years have passed, and I don't race anymore. But I still go to the gym and I've kept the same pre-workout routine. Half a clifbar, coffee, and Liquid IV. One thing that I recently noticed about the Liquid IV is that the first ingredient is Pure Cane Sugar. My question: Does the Liquid IV or any of my pre-workout routine have negative effects on my body?
