Cycling Nutrition Deep Dive - Can We Learn From The Pros?

Do you have any questions about nutrition for Conor & Tim? 🍕

[@did4h2k]

my diabetic ass dies just thinking bout 120g of carbs per hour ;) especially since all those energy bars just shoot right into your blood... how could i keep my energy up? right now (i am lucky enough to have a bluetooth glucose sensor) i just ride and when i am about to bonk (closing in on 70 bloodsugar) i have a snack, like a snickers (if i eat more i go above 200 super fast). that happens every 1-2 hours, leaving me with roughly 15-30g/hour. i dont too ride fast, but i try to cover some distance.

[@TwowheelSherpa]

😂 so true

[@inz_uzi]

The most cost effective solution is table sugar. It contains glucose and fructose at 1:1 ratio which is optimal for maximising carbs intake. You can buy 1kg of sugar for less than you pay for one gel. You can have it as a drink. I prefer to prepare a concentrated syrup (you need to heat up the water to dissolve that much sugar) and store it in a soft flask. I sip it from time to time and drink pure water. It separates nutrition from hydration and it helps to get rid of the sweet taste from my mouth. I also add a pinch of salt with potassium (low sodium diet salt) and magnesium citrate to cover electrolyte demand. I also add a bit of citric acid to make it less sweet. If you'd prefer using maltodextrin or glucose or fructose you can also buy it cheap as dirt and prepare your own solution without any artificial flavours or preservatives for the fraction of the price. The sport nutrition products are a total rip off

[@chrisridesbicycles]

If you have another hour to wait for the stuff to dissolve. - You can get plain maltodextrin and fructose relatively cheap and mix it yourself. It might not taste as good but it works just as well.

@10:32 is why most cyclists are portly hehe. They think 'carb meal' is a fish and chip which is pretty low carb but WAY too much fat! Just that plate alone would have around 80g of fat in it. That is 80g of fat that will be stored in your body fat stores!

[@sethgriffiths6539]

Conor's smile was growing exponentially during that interview as now has carte blanche to eat an entire army of food before, during and after every ride....

[@fe_ciclista]

I'm an amateur cyclist who race local crits monthly and granfondos here and there. I have lost roughly 13kgs so far, from 87kg in 2020 when I began cycling to 74,5/75kgs now. In the process I became kind of carbohydratefobic, because I lost weight eating more proteins and fats and everytime I tried to rise the ammount of carbs in my diet I've gained weight quickly. Restricting carbs is not a problem when you're doing off season miles, but then come the interval sessions and then the races and I was always hungry and feeling underfueled. Now it seems I've found the right way to go. I'm eating way more carbs, mostly whole grains, oath and muesli and a lot of fruits. Lots! Also rice and specially plain pasta. The day before races I'm doing just like Tim stated and eat lots of pasta. During the race I try to keep at least 80-100g/carbs/h between gels, sugary snacks and sport drinks and it works really well for me. I'm a decent passista and to ride at zones 3-4 the whole race takes its toll

[@speedsociety9177]

Interesting, what did you change so that you are not gaining weight anymore on high carbs? I am kind of in the same boat, not really gaining weight, just restricting carbs for health reasons.

[@matthewchristian1716]

I had a very similar experience, my weight would fluctuate a to due to an unhealthy cycle of keeping carbs incredibly low and relying on a high protein diet, which would leave me constantly craving and feeling under fuelled, especially as I wouldn't consume enough on the bike. Every time I started to increase carbs I would gain a lot of weight which resulted in me restricting them again. September last year I changed it completely and focussed meals on the carbohydrate with protein being the supplementary part (years of rugby & gym in my youth always had me focusing on protein first). I don't think I have had a low carb meal since although I do keep an eye on the amount of carbs proportionally to my life / training demands (so its not a free for all) & I have found that training & performances are better & my weight is lower and most importantly stable. I try and do any intense sessions in the afternoon (if week days) now so that I am fuelled & do some fasted rides at low Z1 & Z2 but even those aren't totally fasted as I usual take a carb drink mix but might make it half a serving. I also trail & fell run so I rarely find the need or desire for a low carb easy day, as usually an easy day is going to follow something painful! If I am having a total block of time off then I would just switch to a more balanced diet.

Leanest and healthiest cultures on earth did a high carb low fat diet. Carbs are self limiting. You can't eat more than you need. Fat though.. you can smash thru boxes of donuts and gain 200g of body fat in a day just trying to get carbs but to get 200g of fat from potatoes you would need to eat 200kg of potatoes! Keep an eye on fat intake if you want to be able to burn more body fat and have better health. I try to keep my fat under 10g a day if Im wanting to drop body fat.

I tried 70 miles last week I fasted until I done the first 30 miles. I only managed 67 miles but the last 20 was horrendous I had no energy at all. I’m doing a charity even this weekend which involves climbing a mountain, kayaking 14 miles and then cycling 34 miles so this video has been a huge help. I’m carb load the night before instead of 2 or 3 days before.

[@themindgarage8938]

Eating before you're hungry is the key. If there's a time to not take carbs it's the last half an hour not the first!

[@dakalla]

If you are doing a long event you need to start fueling right at the beginning. I always take a banana with me for after the warmup ride and then eat every 45min something. A cereal bar, gel, cliffbar, cake, something from the bakery.. whatever. The key i found in the last years is to eat regularly on every ride thats beyond 1,5h. This also convinced my GF who runs halfmarathons from time to time. Last time she was nearly 10min faster and said it felt waay easier.

[@christophermarwick3619]

This is really really great. Good effort on this one guys

[@darrylhuculak4996]

I've always looked at calories more than grams when on the bike. After my pre-ride snack of 1 cup oatmeal w/raisins (about 200 cal/30g), I eat one bar (260 cal/40g) and one gel (100 cal/23g) every 90 minutes, then gels every 45 mins after that. Works out to about 1000 cal/200g of carbs for a three-ish hour ride averaging around 200W. Based on what Tim said about amateur athletes, I guess I'm still in the ball park at 67g/hr. However I do find I need to make sure I eat enough the day before and after the ride to replenish my energy stores, otherwise I'm resigned to the couch watching GCN+ for a couple of days afterwards. Not the worst outcome...

SO helpful. Answers the question as to why when I fuel aggressively on my 4-8 hour rides that I feel so much better than the 40-60 g I was trying. Gotta eat more !

[@AutiSam1974]

I'm skeptical of the claim that there are no negative health impacts "whatsoever" (as long as the energy balance is maintained) because the energy is just being used , I'd like to see some peer reviewed studies to back this up. The carbs have to be processed by the body first, what about impacts of massively increased carb processing on kidney, liver, brain, pancreas, digestive tract, gut biome, oral health? Professional cycling is not a sport noted for its duty of care to athletes, what about long term impacts of doing this? A deeper dive and some health warnings would be helpful on this subject. Interested to know what others think.

[@derekhartloper11]

Totally agree it's gotta be unhealthy to slam back as many carbs as possible! Humans evolved as endurance athletes but our glycogen stores are only about 2000 cals, so intense activities should not last more than about 3 hr, at which point we hit the proverbial "wall" (ie: bonk), and have to drop the intensity or stop and recover/ refuel.

[@MPSwimAcademy]

I think that it is better to discuss more explicitly than just mentioning the groups of macro and micro nutrients. numbers, exact nutrition, details

[@nickstratford]

It's interesting that endurance diet is so vastly different than everyday nutrition where the general consensus is to avoid sugar at all costs since this causes blood sugar spikes and type-2 diabetes.

[@kaltonian]

one thing i learned about weight training was regardless of what people advise you to eat you have to find out what your body requires in order to make gains, for me it worked out to 6 meals per day with little snacks in between, as other might need 8 meals or just 4 meals per day with snacks, other thing is your body can only process a certain amount of proteins within 3 hours otherwise your body just gets rid of it, carbs depend on other foods & your activity to be be digested & turned into fuel, there are 3 body types & you have to find out which type you are, good thing about carbs is you can just keep consuming them as long as you keep up your exercise & fluid intake, rest is so important as well as massaging & ice cold baths, good clean oxygen is another one, trouble is nutrition such a vast topic & there will always be new revolutionary methods of refueling the body, do what works for you by experimenting all the different methods.

[@matthiaswuest7271]

One of my biggest barriers to getting enough carbs on board is cost tbh.

[@ffskierdune6226]

The top level pros have fueling stratiges based on a number of factors. Keep in mind that the very best, Pogi, has a blood lactate level still under 2 at 300 watts. This is still zone 2 for him. His need for carbs is much lower, once above this level the demands for carbs increases big time. Fueling strategies are primarily based on lenght of event, level of intensity play and what the goal of the event is. They discuss this with their coaches pre race and will adjust as the race progresses. They will being fueling and drinking right away when riding. They could have stickers/reminders on their bikes when to eat and drink. They may also have reminders on their computers. Its not a perfect system, some have tried, such as Ineos, with live feedback.

[@The_BigBookClub]

This is very good information, thank you. However, it would super useful to have a similar discussion but for cyclists with diabetes and/or those that cannot consume as much carbs. I knows its a complicated topic, but I wonder if there are any recommendations that keep in mind those that have this issue. Perhaps a mix of lower carbs plus fats, ketones, or protein? On that note, let me just rant a bit and say that I am so dissapointed about the UCI banning glucose meters during a race. I think that is ridiculous and goes against those who have metabolic issues and are doing there best to do sports. For consistency then should just get rid of power meters and HR monitors.... ridiculous. Thanks again and sorry for the loaded comment.

[@donwinston]

Eating carbohydrates, including sugar, does NOT CAUSE DIABETES. The only way to get diabetes (type 2) is to get fat. It's the fat that causes insulin resistance and/or suppresses insulin secretion. Not everyone gets diabetes at the same level of "fatness" but it is in fact "getting fat" that causes diabetes.

I'm a bit confused by his comment about carb intake being basically the same for women as it is for men.

25 kCals per km. Energy per distance. Negates speed differences. Extra 20 kCals per 100m climbing. I had this discussion with Audax UK in the early nineties. As a result, they removed "8 kCals/min" from their handbook. 8 kCals/min at 16 kmh is far too much, while 8 kCals/min at 40 kmh is not enough. Energy per distance stands because riding 1 km requires the same amount of air to be moved whatever the velocity. Ignore anyone who quotes kCals per time.

I prefer to prepare a concentrated syrup (you need to heat up the water to dissolve that much sugar) and store it in a soft flask. I sip it from time to time and drink pure water. It separates nutrition from hydration and it helps to get rid of the sweet taste from my mouth. I also add a pinch of salt with potassium (low sodium diet salt) and magnesium citrate to cover electrolyte demand. I also add a bit of citric acid to make it less sweet. If you'd prefer using maltodextrin or glucose or fructose you can also buy it cheap as dirt and prepare your own solution without any artificial flavours or preservatives for the fraction of the price. The sport nutrition products are a total rip off.

[@themindgarage8938]

Make your own drink mix from table sugar or maltodextrin. I bought 5kg of malto for under £15 which is like 200-250 gels worth.

What's with the Fish n Chips? Pro-level cyclists are different than most people. The demands they ask their bodies to do are completely different from non-pros, and weekend worriers. Do not compare yourself to them. In Dr. Strobel's 2022 study, he divided the Giro into Flat, Hill, and Mountain. CHO demand was highest in the Mountain stage - 357 grams, Hilly - 338 and Flat - 266 grams. The riders consumed the most CHO at dinner and the least amount at breakfast. As an experiment (for not GCN presenters to try) try and eat 80 grams of carbs per hour for a 3-hour ride. Unless you have trained your stomach over time to be able to absorb this high amount of CHO you will enviably have a variety of gastric distress issues which will affect your performance 100%. Also, most pro cyclists have an Ectomorph body type, very lean, the same type as most of the GCN presenters except Hank and Manon. Fuel for the ride and effort.

Any tips on how to keep teeth from falling out when eating and drinking that much sugar? Especially given that most energy mixes have added acidifiers?

[@belap7131]

Toothbrush, toothpaste.

[@themindgarage8938]

Maltodextrin is much less bad for tooth decay than sugar because the molecules are larger and I don't think bacteria can break them down as easily. You can make your own mix and add your own flavours that don't involve citric acid.

[@Siblove7]

​@@belap7131 toothbrushing directly after eating sugars is actually worse, cause the teeth are sensitive from the sugars and brushing is too aggressive. Wash down the sugars with water during the ride and possibly gargle with water mixed with baking soda after ride

[@FrapsomaticalOption]

I just finished doing a 8-day/800km bikepacking trip from Germany to Italy. My plan was to compensate for most of the calories through isotonic powder, but sadly the combination of citric acid and sugar gave me a pretty bad tooth ache on the third day, so I had to stop and switch to eating more, which got way more expensive and I couldn't eat the 7000 calories each day, so I definitely had a deficit at the end, but never felt too much burnt out and didn't bonk once. Sadly there aren't many isotonic drinks without citric acid - which obviously is bad for your gums - and the ones available that I'm aware of are way more expensive than the stuff I use now. Any recommendations on that?

I now also add powdered electrolytes as well. As an after training drink I bung in a dose of protein.

Is there a direct correlation from w/kg and hours of training to how many calories you should consume? I would expect so, but I am not that savvy at the maths

[@maximiliandeisz2961]

well there is a semidirect coralation. First you have the energy your body can get from body fat. Than there is energy your body already has available(doesn't really matter on longer rides). Then there is the energy you need to consume to be able to burn it(the carbs you are eating). The more energy (actually) put out(so not power to the pedal but the energy your body expends) is what is important. As you have a base level energy expendature(for just living) and the efficeny of your body depends on a whole lot of factors the corralations work as a rule of thumb but the best indicator is the calouries(so energy) you use to ride rather than power to the pedals

Presumably as long as the carb burn is matching intake, no issues with insulin resistance, and later diabetes. But Ii have wondered if carb loafing day a day before s big event will trigger insulin response, negating the effects of the card loafing - and if done often and long enough could lead to diabetic type issues in time. Thoughts will be appreciated

[@andreasolsson2336]

supersapiens + trial and error. these things are individual specific.

[@donwinston]

There are no "negative effects". Eating carbohydrates, including sugar, does NOT cause diabetes. Getting fat is what causes insulin resistance and/or insulin secretion deficiency. No elite cyclist in the entire world has ever gotten the 2 diabetes. Even after they stop cycling they will never get type 2 diabetes as long as they don't get fat.

[@swites]

Carbs aren't the issue in and of themselves. The issue is being unable to process carbs properly and get them out of the bloodstream and into the cells where they're able to be converted into energy. This is caused by insulin resistance. Which is caused by a buildup of fat within the cells( over time). Or myocellular lipids. This blocks the insulin receptor sites so insulin is unable to transport the sugar in the blood into the cells. So sugar builds up in the bloodstream and stays high for extended periods causing damage. Most people get insulin resistance by being sedentary and eating a standard western diet full of high fat/ high sugar junk food (~50:50 carb:fat ratio by calories- chips biscuits cakes cookies chocolate, pizza, burgers, kfc and soda all consumed together), and too much alcohol over time. So the important thing is don't eat high fat/high sugar processed foods unless occasionally. It's less satiating so we eat more volume than we need often without realising it, leading to weight gain ==>overtime leading to a buildup of fat within the cells===>insulin resistance==> unable to process carbs properly. In other words if one is metabolically healthy no issues with carb loading. All it will do is top up and saturate ones glycogen stores that will mostly be burned the next day. Further stimulating metabolic efficiency.

You need to think of your glycogen stores as a fuel tank. I you are healthy and fit then you shouldn't need to fuel any ride of less than 2hrs (you fueled the night before) And then refuel when you get back with carbs and protein. Over 2 hours then probably start fueling after 1 hour. Depends on intensity also

[@dakalla]

I would consider myself healthy and fit, but 2 hours are too long for me without fuel. I cant do full power in the last half hour if you dont eat from the beginning. Maybe glycogen store capacity is different on each person?

Yes, this would work. I would also add some protein powder to balance it out. When doing long events 250+km I have used both the powder. and the liquid versions. Keep in mind that you need to mix it very well. Also, the benefit of powder vs the oil is you can increase the fat content without getting the disaster pants. Test you level of tolerances first.

The key point: kzbin.info/www/bejne/f5-3hqloab5ni6M and also kzbin.info/www/bejne/f5-3hqloab5ni6M - "perhaps people can absorb and use more carbohydrates PROVIDED THAT THERE IS DEMAND for carbohydrates". If you are nearing the level and training of an elite rider, there is demand. If you aren't, and eating like a professional - you'll just get fat. Don't eat like a pro without putting out the power of a pro. Eat at your personal physical capability, and slowly build. It is absolutely amazing how professionals are pushing the boundaries of their biology. I'll personally continue doing my fasted rides - I'm in it for long term health. I need to eat far less than I ever did during extremely long rides thanks to that kind of training. 8 hour days in the saddle, 5000 calories used up, and no hunger during the day. It's the kind of ride that stays Z2, and doesn't use up carb stores and just runs on fat.

How does protein consumption fit into this strategy? If athletes are supposed to consume 2-3 g protein / kg body weight per day, how should they balance carb intake with protein intake?

[@themindgarage8938]

Endurance athletes don't really benefit from more than about 1.6g/kg in studies. Protein is pretty important but definitely shouldn't be eaten during rides, only afterwards. And in my personal experience it's not super hard to get enough protein - most "carb" foods (bread, pasta etc) have about 10g of protein per 100g carbs and as an athlete you'll already be eating a lot of those. Just have a decent protein source in each meal and maybe some higher-protein snacks (greek yoghurt is good for this) and you'll be well above 1.6.

[@SamuelBlackMetalRider]

I concur. Protein for recovery, 2h/kg is more than enough for us. Above is for bodybuilding. I’m vegan and I get +100g of protein per day easy

[@zavman109]

They are also pretty good during a ride and a famous „bonk pick-me-up“ from the service station. Look for those where glucose-fructose syrup is first on the list of ingredients. Should be almost perfect based on what he said.

[@derekhartloper11]

Dont forget that on average we store about 2000 calories of glycogen (carbs) in our bodies. If you burn 10 cal/min which is fairly intense, thats 200 min or over 3hr of fuel. So for moderately intense endurance activities, you dont need to fuel during, for up to about 3 hr. Thats why the famous Boston marathon "wall" gets hit around the 3 hr mark for most normal runners. Thats also why its abnormal for humans to do intense endurance activites longer than about 3hr. We are not evolved to do it, so ultimately its not healthy. I suggest normal folks should consider their overall health and fitness, when training. Its a balance, unlike pro sports and ultramarathon events. Food for thought.
