Video: Remi Gauvin & Lee Jackson Attempt to Burn 10,000 Calories in a Single Day

May 14, 2020 at 23:24
by Rémi Gauvin  

My roommate Lee and I have been talking about the 10,000 calorie challenge for over a year now after seeing someone else on Youtube try and fail... Then the other week Bas Van Steenbergen went for it to raise money for the Canadian Food Bank and completed it like a champ! It took him all the way until midnight, and the last few hours looked pretty awful. So awful that Lee and I decided we had to try for ourselves. We committed to a day and came up with a quick plan that included hiking, road biking, a gym workout, some running and a ton of mountain biking. We never got to the gym workout because by the time we got to that point we figured more riding would be better bang for our buck. And we were scared anything heavy might just break us in half. It was surprising what we were capable of once we had our goal and got into our rhythm. That doesn't mean that, when the sun went down, 10,000 calories came to us easy.


bigquotesDefinitely getting into a different zone here. It sort of sucks... But its cool...Lee Jackson

We went from before sunrise until well after sunset to try and complete this challenge. One of us comes out victorious and one of us might have to revisit on another day... Or not!

 You got robbed on the Calorie counter - why would it be registering such a lower amount burned compared to Remi doing the same activity? You guys will have to switch wrist straps next time ;P

 How does these soft calculate Calories loss ? I mean, if it's only distance and elevation gain or loss, its false. The pace you ride while descending on mtb down a trail (jumps, wheelies etc.) you burn far more calories than someone rolling at a cool pace... or me for exemple. And you burn far more that if you were on a road. So i guess you've done it ! ;-)

 @kegron:
I guess it's more based on heart rate etc, but I could be wrong. Nonetheless I would guess that he did it anyway because these things can't be very accurate and more of an educated guess. If anyone knows how it works please let us know.

 @kegron: As Loki mentions the measurements come from an optical heart rate monitor. It will determine hard you're working using heart rate zones that will either be calculated based on your age or on data you have entered. This exertion will be combined with your manually entered height and weight to estimate how many calories you have burned.

Obviously this involves multiple assumptions based on the average body, so it may or may not be very accurate (and this accuracy varies with the quality of data you enter). This could be problematic if you're trying to lose weight and hit a specific calorie deficit but it's helpful for planning things like how much food to bring on a big ride. Manually entering things like your maximum and resting heart rate makes the calculations more accurate, but only if the numbers you put in are accurate. If I were to eat based on the calories my watch told me I burned I would get very fat.

 @WAKIdesigns: I had the opportunity to do a long climb in the Himalaya. Our goal was to eat 5500 calories a day but was challenging. I would have 3 snickers bars for first lunch then a pack of mr noodles with a good chunk of cheese for second lunch when we stopped walking. The crazy thing with that was we still were burning more calories than we could eat.

Great work boys!

 @WAKIdesigns: hit almost 8000 calories on the first day of a 2 day bikepacking ride, 14.5 hours in the saddle, second day as eating in expectation for similar when a pedal sheared out of the crank 7.5 hours in. the intestinal distress as all those calories tried to go somewhere was far worse than the previous day of riding

 You guys make me feel like a woose, I am impressed with you though. I eat 2-2.5k + fill for training but never above 3,5k total a day. My belly and my ass wouldn’t take it. I am tight inside then. Max single feeding in calorie counting career was 2k. I feel like crap every time I eat over 1.5k in one feeding. Lots of Fat + protein stuffs me instantly and for along time. Cheers!

 @Brownsworthy: I eat 2k base if I try hard. 2.5k is easy on regular basis. On a ride day I add approximation of what ride took me. I count 10kcal/1minute of XC ride. I burn at least 300kcal by commuting. I am still not losing weight too fast.

 Years ago I ran treeplanting camps. Its extremely hard work to make good money at it, longs days, full body exertion in steep, rough terrain. I don't know exactly what people were burning calorie wise but high production planters eat huge amounts of food and lose weight during the season. Cooks, who are not counting calories but are figuring out what quantities people are consuming every day, would say that some people were eating 8-10k calories daily. Now I teach university instead, I am pretty active still, but I have to really watch what I eat to avoid being more massive than I am.

 @acrowe: for people who are not moving much during the day, like having a desk job, counting calories is not enough. You can go to the gym, commute on bike, ride few times a week. Doesn’t matter. You have to watch what you eat/ drink and when. Then each person metaboliizes different things a bit differently and responds differently to different kinds of exercise. We react differently to gut flora. Some have bigger or smaller cravings. I for instance stay off sweets because they increase my apetite and cravings. Beer which has high glycemic index is for me a sort of FedEx Express transporting itself and all current contents of my stomach straight to my fat cells. All fine in proximity of exercise or during the exercise, but not away from it. Skipping breakfast or dinner, eating within limited time windows is not some sort of regime for office rats to stay lean - it is convenience.

 @hamncheez: Big Grin Well, the game does change some, if your 21 and chock full of chronic health issues Wink .
Even thou I try and hit the bike/trails every day, for at least 30 minutes or more. It takes a loooooong time to bring your weight down. And it doesn't help any that i'm 6-2, 230-240lbs, and have a huge appetite/sweet tooth.
Even thou most of my diet is fresh fruit, vegies, whole cereal, home made foods, the weight ain't going anywhere... I did a 40 miler of gravel/road the other day, the last 10 miles were brutal. Legs just about didn't have it in them, but surprised myself. I did make it after 6 hours in the saddle, with short walks/breaks to stretch my legs. Too keep me going, I ate a mix of dried apples, raisin's, whole oat o's, and whole wheat shredies. Before I left, I at a homemade burger, homemade 60% bun, laced with lettuce, tomato, ketchup, and yellow mustard. For desert, bowl of dried raisin's & shreadies. Kept me going for a good 5 hours. In the last hour I was running out of steam fast. I have no idea how many calories I burnt, I would guess a good 5,000, or more. When I hit home I was raving mad hungry Big Grin . Chowed down on a nice helping of homemade potato/bacon/cream casserole, and bunch of dried raisins for desert. Guts didn't explode that night/next day, but me legs were shot. So I guess I ate exactly what I burnt off...
Like waki says, you have to figure out how many calories you burn in an average day, and eat slightly less than that. That's where modern smart tech comes into it's own, you get a perty good idea of what you burn, then eat close to that, leaving some room for your body to eat up some of it's fat. Just remember not to take it to far Wink , you want to stay in a healthy range. Best place to find out is your doctor/nutritionist, they'll tell you exactly how many calories your body needs to function, and you work in those numbers.

 @wcr: go low carb. Only thing that really worked for me
  • 2 1
 @hamncheez: We ar all different, sure but for most of us (that means results may vary, check several approaches what suits you) Carbs are a better fuel for sports with highly variable cardio, like MTB. Period. Bodybuilders or marathon runners can indeed have good results with high fat diets, but even die hard keto fans from Joe Rogan circles are now getting off of it. Carbs like everything this good have drawbacks: not that easy to munch just high quality carbs because it can be like eating air - fruit or quality fillers like oats, rice, potatoes, theya are not that filling so you keep being hungry. Carbs, especially fast carbs (that involves banana) make you hungry - all the time - as simple as that and all this nutrition guru bollocks about fiber is plain ridiculous. So carbs put on you bigger responsibility of staying disciplined. People who munch high fat, high protein diet, don't do it out of any higher virtue like health or performance, they do it because iti s convenient! They are les hungry during the day = they don't need as much discipline. Come on BBs munch steroids and other crap, marathon runners and tirathletes are also messing up their bodies by burning massive amounts of calories, burning muscle, stiffening up their vains and arteries, steady state cardio, all in repetititve manner with ease of creating overuse injuries, then some influencer aholes and btchs are talking some healthy diet BS. Eat carbs near the exercise and you can be sure they will end up in your muscles and your culon. Then it's about combination: eat carbs with fats and meat, with little or no veggies then you can be sure it will end up in your vein/artery walls and fat tissue. Throw in alcohol, especially highly glycemic beer while sitting on sofa and you'll definitely get it all in wrong area of your ass.

Like Jeff Cavaliere has said: losing weight is about discipline. Even all that science with Time Restricted Eating is mainly BS. If it wasn't people making their living on building muscle and losing fat would sing about it. They don't. Their coaches are putting it simply (like Christian Thibaudeau) - TRE, IF are methods of coping with lack of discipline. If you make your body used to eating in limited time windows, you are less hungry outside of those windows and can stuff your gob full of anything within those eating windows. But there is no going around the fact that losing fat is counterproductive to building muscle or at least very hard to achieve, hence you have to cycle your training and nutrition throughout the year. again triathletes don't care, they don't have muscle, they need steady state cardio, they build muscle as cross training only to not fall apart. I won't take a single advice from a marathon runner who looks like he just escaped from Gulag and run barefoot through Syberia to India. Muscular atrophy specialists.

You can incorporate various methods to protect your muscles and go down in weight but it really boils down to discipline. What helps me is cold showers, lifting heavy, doing sprints and TRE - I skip breakfast, I eat lunch like a pig, eat a bowl of muesli in the evening. Then add food for training, accordingly to burned calories. Then I have 1-2 cheat days in a week and try to have one day a week with 500cal deficit. Usually a day when doing an easy or medium ride. Always finish it with protein. When on deficit I always overfill protein. It is still hard to increase strength when on maintenance. When bulking up, I can add 7.5-10kg on squat per month, 5 per month on bench. Easy. In maintenance: at best 10kg per 2months. I improved my bench only 5kg since I started dropping weight in February. But! I improved my push up count from 30 to 50. Pull up from 6-15.

Oh I'd forget psychedelics are good with cravings, maybe you should treat your sweet tooth with some LSD @wcr. Other than this, eat laxatives like twice a year. Clearing your gut from bacteria flora that loves tasty food helps with building "dietary" flora loving holistically healthy food in line with all the lovely influencers out there.

 @WAKIdesigns: Here here Mr. Waki!
And your nuts if you think i'll start doing dope, you got another thing coming boy... Wink .
Big Grin
Your are right on low carbs, especially for my FM/ME/CFS/IBS. A low carb, high protein diet is the way to go, and lots of dairy to help the gut flora. That, with lots of canned beans Wink .
Why do you thing people were so healthy back in the day... The advent of fast food/junk foods/fad diets had a lot to do with the start of obesity crises, society faces today. If we go back to the basics of whole, filling foods, then you will see a surge of "healthy" people. Another fact., fad diets make a person way more unhappy with there life, which in turn contributes to all the health problems. It's a vicious cycle, especially for vigans, and even vegitarians (misspelled on purpose Wink ).
So I follow said diet... Eat mostly fruit/vegies/grains, and have a proper serving, of any kind of whole meat, at either lunch or dinner.
I think you won't kill yourself if you do that …

 @wcr: it is all quite personal but one has to try several approaches to be able to say: this really works for me. Lifestyles vary, we have different schedules, preferred exercising windows, different access to foods, more or less chaotic/ organized work schedules, we have different jobs. Like tree planting VS office job, or being a personal trainer or a guard at the entrance to some facility. You can have all the best intentions and the best diet plan, but maybe you have a spouse who is active in a completely different way as you, or just eating snacks in front of TV. Then you maybe go for a group rode and your buddies want to drink 3 beers and eat a burger post ride. Or a thing like sleeping: all those influencers giving advice on sleeping - oh yeah great, tell it to parents of small kids!

Sometimes when I talk to people at work and diet comes up, there are some incredible things coming up. Incredible, incredible things... one person decides that cutting weight by not eating is better than exercising... why not both in a measured manner? Someone else claims humans do not need to eat extra protein. Someone else says sugar is toxic. Not to mention people who do Thenx tabatha bright before bed which Chris Heria claims, burns fat while you are sleeping. Then I mention counting calories and some people start flipping out. I get more rolling eyeballs and gasping from saying that I count calories from time to time, than I got when I said I ate fly agaric mushroom and didn’t even puke...

Reading on TRT and talking to people doing it right, nobody is really getting their balls shrink or prostate Turning from onion ring into a donut. Some take so much testosterone they have more of it than 21yr old, some take enough to get levels from being 30-35. Idea that there is some natural hormonal balance is insane. Who doesn’t enjoy a GF on pills over one on Catholic calendar? Come on... there’s difference between a bloke getting his testosterone level from being 30 and Kali Muscle...

 The thing about pickle juice is you have to be prudent with the intake. Too much (like more than a couple of swallows) and it's a one way trip to gastrointestinal distress. This no doubt varies from person to person but it's no joke.

 It's a lot of calories to get through! I managed to burn nearly 11,000 calories doing the South Downs Way a few years ago (100 miles p-p, 11,000 feet climbing) and bizarrely felt fine the next day. Two days afterwards though I was dead to the world.

 Wasn't something published that most people cannot burn calories at more than 2.5 times their resting metabolic rate, or ~4,000 calories per day? In any case, like @kilo11 said, I'd rather try to eat it. I know I can accomplish that!

 Maybe actual food burned as fuel, the body stops at a certain point but we didn't do it to try and get skinny! As far as calories as a unit of measurement; the more you move the more you burn!

 I believe it's just that you can't consistently burn more than that over a long period of time--like more than a month or two. We've all got fat stores to burn & your body will burn muscle too, but eventually it'll catch up with you.
