Carbs Vs Protein Vs Fat - What's The Best Fuel For Riding?

[@rickvolkman6548]

Tried to do my first Century ride last summer, made it 94 miles before being rescued. I wasn't so tired that I needed to sleep, my muscles weren't sore, neither was my backside. I just couldn't go on. Now I know that I had way too much protein and not enough carbs and that what I did consume was too much at one time. Summer shall come again, and so will a better prepared Century ride! Thank you GCN for this video!

[@brendonnoble5227]

Next time you will not only succeed, but enjoy it more. Take advantage of a group ride or Grand Fondo event for part of it if you can. The companionship really helps when you´re flagging.

[@lonegroover]

Good luck, it's very doable. I'm 61 and did a 200 mile ride last year.

[@williamwightman8409]

Try to ride long slow rides with reduced carb (eventually no carbs and start fasted) inputs. This will allow your body to adapt to burning fat. This will take about 10 weeks minimum. If you are fat-adapted you will still bonk if you ride too hard. The difference is that all you have to do is slow way down (say from 20 mph to 16 mph) and get fully aerobic and your fat will get you home.

[@MichaelBuck]

I already knew the basic outcome having done several Triathlons, especially Olympic/International Distances. The TRAINING will tell you very quickly what works and what doesn't. What I learned is that PROTEIN is for before and after training runs and races and is used primarily for muscle building and recovery. The Fats are for long-term diet and training and the Carbs are for the day of riding. I incorporated slow long-distance training with interval training, and with triathlons, I rotated Swimming, BIking, and Running throughout the week. It really pays off to have a regimented BASE DIET in place that creates the reserves for when you need them. You cant just CREATE RESERVES or POWER or ENDURANCE on Race day through that day's diet regime. Usually, race day is a cumulation of a strict diet and training regimes. Then on race day, all you need is the proper carb inputs and the right times so you don't get gastric problems and so you can fully utilize the carbs you are getting. The whole aspect of Diet is often overlooked by people that are new to the training for these types of long distances. You have to TRAIN your body to accept the new diet as well as accept the carbs during your training runs. It's a long process but it pays off in the end when you find you can get through a race and at the end feel like you could keep going a bit longer if needed.

[@jayclark5034]

@@NYGiants4Life Generally agree with Ludde Algell. I'd be sure to mix some intervals in there to challenge your body and drink plenty of fluids, kinda hard to overdo that. Good balanced meals (at least on a whole day basis) and not too many calories. Diet is #1 with weight loss, excercise second. Gotta get a good idea of what is just below your actual needs. I also group my eating into one part of the day and zero calories in between, helps keep your liver cleaned out (assuming the quality of food you eat is good). It doesn't have you losing quickly, but slow and steady is easiest on your body long term anyway. My wife was able to lose 1 lb/wk, which came out to ~50 lbs in a year. I'm 10-15lbs over my ideal weight and I like beer, so until I drop that I'm probably not losing any more! 🤪

What we all expected, but thanks for putting it to the test! On group rides with big breaks (30-45 min,) a little protein can make sense mid ride because you have time to digest it. During our breaks, I do a little sushi with soy for the salt, and I usually feel stronger on the way back than if I only eat carbs. But that's me, and only after a big break. The real point is carbs carbs carbs.

[@ianlaker9161]

During my 40 years of cycling the mantra has predominantly been carbs. Slow burning carbs just make logical sense. Overnight oats or flapjacks see me through gym work and long rides combined with gels/gums.

[@philadams9254]

Most of the riding would be fuelled on yesterday's carbs though - stored as glycogen in your legs already. It would only be a fair test if you pre-loaded each fuel the days before.

[@stevenbell482]

my thoughts. greets

[@goku445]

Agreed. And only carbs taken during the effort would be useful, fat and proteins are too taxing to digest to be used efficiently as energy.

[@floridrummer88]

well..science is quite clear that this is only true for about the first 1,5h max...as they rode 3h, the right nutrition definetly comes into play..no matter how good your carb preload has been, because glycogen storage is also limited.. 🤷‍♂️

[@MarquitoRH]

In humans, glycogen is made and stored primarily in the cells of the liver and skeletal muscle. In the liver, glycogen can make up 5-6% of the organ's fresh weight, and the liver of an adult, weighing 1.5 kg, can store roughly 100-120 grams of glycogen. By morning, 60-80% of the liver glycogen has been secreted and used by cells throughout the body. However, muscle glycogen levels remain high throughout the night and are high when you wake up for your morning run because it isn't secreted from, or consumed by, skeletal muscle cells while you sleep.

[@jirihutecka9020]

The biggest mistake I was doing when I started riding was eating a lot of fats and fiber during rides like all kinds of nut bars etc.. Now I know it's useless. It just slows down digestion. All you need are carbs ideally mix of slower and faster carbs like maltodextrin, glucose and fructose.. Only if it's long ride like 6 or more hours it's good idea to eat some "normal food" where is also some protein, fats and fiber.. But most rides under 4 hours you are good just with carbs..

[@panzerveps]

I went for "slow carbs", fat and salt as well. Bonked so hard during my first sportive. Was saved by a random Snickers bar.

[@markusseppala6547]

Same for me, when riding 5 or more hours I like to have something solid too like bananas and chocolate bars (ones with most sugar).

[@jirihutecka9020]

@@markusseppala6547 yeah banana, dates, raisins are great. But don't forget they are very high in potassium and it needs to be balanced with sodium. Especially if you sweat a lot you can lose a lot of sodium and that will make you dehydrated.. Water, sugar and sodium are key things during cycling.. I always carry bag of sea salt. So I don't have to buy chips, salty peanuts etc.. I just add salt to my drink or food or I already mix some salt into bag of raisins for example. So I have sugar, salt together.

I don't eat carbs nor sugar. Body adapts after a dozen days but you need to be consistent

[@SirPhillyLeong]

A lot of marathon runners are on fat-based diets these days. Takes up less space than carbs for the same level of calories. Meats tend to clog up your guts and give you a stitch, same with nut bars but your body does need time to adjust to the fatty diet change. I find the best thing is an extra cheesy melt sandwich with plenty of butter and a sugary drink if you need a quick lift.

[@kstethespokes1051]

Would quite like to see episode 2 and how everyone felt the next day.

[@TimpBizkit]

It feels like running in a dream, where each step feels heavy. You just kind of turn over first gear as soon as you come to any hill over 5%. Plus you feel a bit light headed and hungry and the legs feel like jelly. Worst is ketosis into a headwind.

[@danboe4751]

I've done mulitple imperial centruy rides with no carbs. Lots of climbing. I was 100% fat adapted, and had been in ketosis for a year prior. High quality fats were the source of energy. I did great and never bonked once on the ride as my fellow carb riders would cycle through. I wouldn't be as fast up the hills but after the hills I found the other riders were tired and I still had consistant energy. One major difference when I was on fats is that AFTER club rides on a fat diet my energy level was great and I would be real productive the rest of the day, but now that I'm on carbs all I want to do is sleep and eat after cycling.

Being fat adapted is the key. You can't have someone just go out and ride on fats because its not going to end well, right Connor? He would've been better off filling his bottle with MCT oil instead of that over the top nonsense he was eating. Then again, he would've ended up in the toilet anyway because his body isnt used to him taking it. Lose lose either way.

[@Gussy1980]

Agree. This was a terrible video by GCN as Conor wasn't fat adapted. I do most of my rides fasted / in ketosis and I never have issues, and I've often done 100km rides with no issues / no bonking. Episodes like this just do harm to the health benefits of fasting / keto.

Instead of 1.29/ea they are about .09/ea (i eat two so 18 cents ) and work great ! So a MIX of protein, fat and carbs.. but more carb than anything for a ride. I'm trying to cut my carbs, but for a ride i load up via oatmeal. Nice video !! Nice subject/test, and happy for Manon getting the lucky straw... better luck next time guys :- )

[@drmitofit2673]

I thought I was doing okay with the usual carbs, but then one morning I ate two cheese sticks and had the best ride ever. Dropped everyone and didn't come close to bonking. The combined protein and fat encouraged ketosis and fat burning I suppose. Carbs might be better in a recovery smoothie to trigger insulin release to get sugar and amino acids into the cells and rebuild muscle and depleted glycogen stores. I think the key is insulin level: low/moderate when exercising and high when recovering. An insulin roller coaster when exercising is probably not the best thing. Also, consuming so many calories while exercising is not good for the digestive tract. When blood flow is increased to muscles during exercise, blood will shunt away from the intestines, worsened with dehydration. A runner trying to run back to back marathons came to our hospital ER with severe abdominal pain and a CT scan diagnosed infarcted bowel.

[@lachlanmcdermid8539]

Some good tips in this video! Had my first bonk about 20 hours into a 24 hour adventure race. Was on a bike leg at the time and lost all power, all alertness, and was desperately hungry and cold all of a sudden (it was about 4am). I have never eaten so fast in my life when i managed to did a bag of food out 😂 It was luckily a relatively quick recovery and I have since learnt my lesson and fuelled better in future races. I often find it very hard to eat when active as i loose all appetitie but sometime you just need to force it down to keep going!

I may eat an hour or two before a ride, but very little during one. If you are fat-adapted and are able to burn fat, you should not bonk, although I agree that fat adapted riders need to hold back in intensity if they wish to avoid that depleted feeling. At certain times, like when riding up a long ascent, I will nibble on a power bar. After a long ride I am not immediately hungry, just thirsty, but after an hour or so- watch out! Replenishment feels good. I really like a coffee shop after a ride with some nice pastry or a Boba tea.

You have to get fat adapted takes couple months if not longer. I can do 100 mile cycle from eating fats and proteins prior to cycle water and electrolytes none flavoured on cycle itself and extra salt. This test is not a true reflection on how it's done properly. Long term not relying on carbs sugar will give you longer life longevity. The sugar and oils industry are making a packet on your addiction to sugar and it's the canola, seed oils, transfats found in everyday food breads, pancakes, buns, protein carb bars' thats what clogs your arteries nor pure animal fats.

[@chrisfamisaran]

Manin’s reaction to Ollie and Conor’s food choices=priceless😂

[@eclecticcyclist]

The time to avoid carbs and fuel on fat is during the off days, not the days when you're pushing yourself to the max. The body will take around six weeks to adapt to a ketogenic (ultra low carb) diet, then it will run on ketones more efficiently and keep the glycogen in the stores until needed which is what Geraint Thomas did before he won the Tour de France. Overloading with carbs is a bad move as once the stores are full the body will turn them into triglycerides which are the building blocks of body fat. Carbs raise blood sugar which causes a release of dopamine (the feel good hormone) just like drugs, that's why she said she felt good although she was slowing down due to tiredness. Continually high blood sugar leads to chronic inflammation which constricts airways leading to what many riders recognise as exercise induced asthma, it also restricts blood vessels reducing power output, so keep your carb intake down until you need them.

Fantastic video as usual GCN crew, great info and humour! Eat whatever you can stomach on a ride, probably complex carbs at best, and drink alot of electrolytes. But, your diet preceding exercise is more important, since a high protein and fat diet can be used along with proper training, to get your body to metabolize more fats at higher intensities. This will preserve the 2000 cal glycogen stores in the average body and delay the onset of bonking. Remember that no amount of fuelling during high intensity aerobic exercise can keep up with your glycogen burn rate, so you have to prepare in advance. If you try fueling like mad during your big event, you will be sick, no matter what you consume. Just ask any ultra runner or iron man triathlete. Way to take one for the team Connor, oh yes and egg white Ollie lol..😁...

I’ve changed my eating habits to low carbs and intermittent fasting. So I’m now fat adapted. I can do a 4 to 6 hour ride on an empty stomach because I can use ketones as fuel. I do all my sports like badminton and tennis on an empty stomach. It takes a few weeks to get fat adapted.

Just from my personal experience you do need to be fat adapted which takes several weeks before comparing high carbs vs fat adapted ketone energy sources. Being a runner, cyclist and resistance training enthusiast i decided to see how it worked for me. Results suggested that i felt much better with equal to improved performance doing intermittent fasting/low carb fat adapted for all three activities (average running pace on TM for 45 minutes, average watts zwift cycling with mild elevations 1hr and weight training maximum weight for bench press x 10 reps, squats x 15 reps, max chinups to failure. I was surprised and I believe research going forward will be positive with many high level athletes moving in this direction.

I think every body is different. Here is what works great for me. Here in the US we find carb/sugary gels (Gu and some others) and I have between 2 and 3 of those per hour. So that is between 200 and 300 calories per hour. Around the half point of my ride I eat a quarter cup of a mix of nuts (here in the US is called trail mix) and these are high in protein, iron, fat, sodium and potassium. I add some extra pistachio because they have a lot of potassium. My drink is normally gatorlyte or just coconut water. I find coconut water works the best for me and it also has carbs, sodium, potassium, and magnesium. By the evening I am normally fully recovered. Of course a good meal before and after the ride is always important.

Back in 1984, I was in 3rd place in a 70.3 mile Ohio triathlon and bonked very hard with one mile to go. In fact, I started sort of hallucinating and ended up in the middle of an intersection staring up at the traffic light, apparently saying, “Wow, look, I’m under the traffic light.” Alas, I finished thirteenth. I remember I had rock candy taped to my Bianchi handlebars, and I hate rock candy so I didn’t eat any. There were no gels back then and only oranges and water were supplied on the course. Oranges produce acid and a thick mucous, so I never ate them. This was how triathlons began; you were basically on your own for food and fuel.

[@gcn]

Sounds Awesome! How do you think you'll get on?

[@julienholmgren1543]

@@gcn Well, as beginner with a few extra kilos (for a cyclist) I'll probably die of a heart attack or something, as 9% climbs are hard for me. Next weekend I'm going to check out the whole ride two weeks before the real thing so I can experience it beforehand. To top it all I'm vegan so I'll have to bring my own food because I may not be able to eat the food they'll be handing out there for all the cyclists. Fortunately, my "plant-based cyclist" book by GCN will help me and my Trek Emonda SL5 will do the rest.

Got a lot of laughs in this video, kudos! Also wishing, you guys had switched diets a week ahead of time so the experiment could be more accurate 🌈 But keep em coming, can get enuf of gcn!

Sir Chris Hoy in the GCN interview with him (worth a watch) was suggesting that you should have protein straight after exercise to help recovery

Enjoyed Manon's "eat at the top of a descent" 🙂

[@ExpressingAnime]

Well I usually do fasted rides(trying to loose weight). I have been on 100KM or 62 Miles fasted and never eaten anything in between. And at the end I felt awesome and make me wanna do it again.

The toughest thing is for people with IBS. Fueling on the bike is a chalenge since some sugars are a no go (fructose most of the time). Really wished I found a better way than just eating maple syrup...

[@chrisgarwood2237]

I don't have ibs, but sugars / gels really upset my stomach, as a T1 diabetic, this is a bit of a problem on some rides, I've gone to Kendle Mint Cakes and they really do help me, apparently it's the mint that helps calm the stomach and is a anti inflamitory..... thinking about his now, this post is probably no help to you what so ever, but I'll still post just in case

[@zubayrbhyat8077]

I did a 38kms the other day on two carb-rich bars in around 2 hours. I used to eat lots of fat before this but the energy levels were extremely inconsistent after adapting to eating fat.

[@bratt-38128]

12 mph for 2 hours. One should not need any food for that distance or time. I'm 60 years old and my solo longer hard rides average 18-20 mph for 50-70 miles. I may eat 2 or three snack bars and water.

[@nk-dw2hm]

@@bratt-38128 how many years have you been cycling? If the person you're responding to may be just starting, overweight, and/or doing high intensity (for them) so why would you expect their physiology to be the same as yours? You also say he shouldn't need any food on a 2 hour ride, then you specify you eat as much as he does on your 2.5-3 hour rides. Get off the high horse or stop being a hypocrite

[@bratt-38128]

@@nk-dw2hm First I want to express an apology to Zubayr Bhyat if I came across too strong. He may be in areas with bad roads, using challenging equipment and may be a new rider. Good luck and fair winds, Anyone riding earns my respect. A beginner cyclist shouldn't be worrying about sports nutrition. As they build up speed and distance, there are many other obstacles they must overcome like position, saddle endurance and safely riding in traffic or a group. Riding 2 hours at low speed, they won't be bonking. Remember an untrained cyclist has 2 hours plus gycogen stores in muscles and liver. At lower efforts some energy is provided from fat and protein. It is true with training and experience, your body learns to store more energy. I said I 'may' eat 2-3 snacks in 50-70 miles at 18-20 mph. Those rides at that pace are 2½ to 4 hours long at a much higher wind resistance. I usually eat one or none. Yes I have ridden a lot but stopped riding for 20 years until a few years back. Starting over I had a few advantages like decent equipment and experience riding and knowing my body. The first couple of years my ass hurt, endurance sucked, speed and power weren't there. BUT I never bonked.

There's a lot to be said for dietary adaption - so if Conor had spent a few weeks adapting to a higher fat/lower carb diet I bet he would fare differently to this one off test. That said, for the sort of cycling that the vast majority of us do then for sure carbs are the way forward. Literally.

Thanks Tim!

[@keithforbes8482]

Connor bunked because it takes months to adapt the body's chemistry to efficiently leverage fats as a primary fuel source. The problems with his bowels has to do with a gall bladder that's not yet optimized for the new diet regime.

[@pinoycommuter8635]

Exactly! Intermittent fasting is one of the best way to be fat-adapted.

[@keithforbes8482]

@@BitCrafted I agree; for that competitive edge, carbs is the way to go and perfectly fine for highly active individuals. Combining them with a sedentary lifestyle would not be smart IMHO. I personally commute 26 km daily by bike and resistance train approximately 4 times per week - all on a low carb lifestyle. Works great for my personal objectives.

Great video as always. It would be really interesting if you do another video riding a specific hill and compare times, but this time usage of ketones, BCAA's and just glucose in its purest and safest form.

BCAAs have been debunked so many times it’s not true. Nobody should be eating their money on them.

[@jasonfenech5347]

@@MarquitoRH That is a fair point and it would be interesting to be tested in the first place. There are also mixed feelings about the usage of Ketones as a fuel source.

[@arhu74]

with pure glucose the osmolarity gets too high, so you dehydrate, better to use complex carbs to keep the osmolarity low

Once pushing DOWNHILL from the Avoriaz to Thonon les-Bains via la Joux Verte to catch the last ferry to Lausanne I bonked so bad my friends practically had to push me. I still cannot understand why I could not just roll downhill… We did make it.

[@questgivercyradis8462]

I'm curious what a more balanced mix would be when well tested on a long ride day. I'm going to test some myself soon - mix of peanut butter and honey with some salt, lil' bit avocado oil for my homemade gel. I think honey dominant, for the carbs, but the nuts and oil offer some fat and protein into the mix. Super high sugar slams my kidneys, so I worry a bit on that!

[@theordinaryathlete]

Watching half asleep, thought i had a crack in my mobile screen @1:59. Great vid , a longer term test would be interesting.

[@HHHSykes]

Connor is a warrior in these videos 😂😂

[@bamffatboi5526]

So when I ate peanut butter went on a pr rode and ran out energy becoming really cold and slow, you're saying i should've brought carbs with me that I ate throughout the ride? Great video, and now i know!

Great video. I learned some things. Conor's Irish, right? Well, if he is, where'd he get that accent from? It doesn't sound Irish.

[@seandurkin2016]

I love the look Olli is shading with. . . To Connor

[@jacksonbangs6603]

I have found that if I eat very little during the ride and then eat a big meal after the ride, my body will just vomit 🤢 up the food. However, if I keep a constant consumption of food during the ride, my body is more able to consume food after the ride. End result is to not rely on the post ride meal for fuel.

[@steveward4790]

Just wondering why GCN are not using an electric camera bike? Would certainly cut down on background noise.

[@buster.keaton]

Very interesting video. As someone who eats a low carb, high fat diet off the bike, I've been trying to determine if that's a good idea on the bike. While I've seen some evidence that long distance endurance athletes can do well on high fat fuel, carbs seem to be "king" for pretty much everyone else.

[@filipviljamaasvensson]

I was just about to post a comment on how testing when keto is to do fat justice in this context, specially since being fat adapted is a bit of a requisite to turn it into useful fuel on the fly. I'm doing lowcarb as well and has just gotten back on the saddle after a long break over "the thing". What are you eating now when riding, if anything?

[@egutzait]

What about alcohol as a fuel source mid ride? It's essentially already broken down carbohydrates (Dr. Bridgewood would know better than me). Wouldn't that make it even more efficient for high intensity efforts?

[@williamleung2935]

Connor!!!!! Bonking first and now FAT consumption, what a team player!!!

[@maxsievers8251]

I'm waiting for the response video on this from Durianrider.

[@filipviljamaasvensson]

So, how about a test comparing being keto vs on carbs? (which is how fat is actually useful it seems)

[@leftylum]

Manon's expressions alone were worth watching this video

[@stgangwar]

I really like these types of experimental videos related to nutrition and fueling that you guys put together! My only suggestion would be if you also applied the selective nutrition atleast the night before also so for eg in this video Olie should have only eaten proteins for dinner the night before alongside eating proteins during the ride itself. Would be an interesting twist to the current video setups!

[@Aanonymous88]

Eating nutrients just before a ride won't realy work unless you have an hour or more to digest it. I can do fasted 5 to 10K run and 50K bike before. I biked race twice just only taking Chamomile Tea, I felt better instead of eating solid and just put more on water and eaten well night before.

7:51 is that the oxygen required for digging into your own fats or is it combined with the exogenous fat intake?
