10,000 Calorie Challenge Aftermath | Scientific Study Results | What Happened?

The aftermath of eating 10K calories revealed! This is the data collected from before, after, 48hrs and 2 weeks after I did the 10,000 calorie challenge and the numbers speak for them self!
I hope this gives you a new perspective of overeating as I found this information very intriguing as a person that not only likes to eat a balanced diet but from a someone who enjoys to eat a lot of food.
Thank you again to Dr. Campbell, Danielle and Shiva for taking my measurements at the USF Performance and Physique Enhancement lab!!

AYOOO!! My name is Stephanie Buttermore in a few words I am a fitness enthusiast but a scientist at heart!
Currently pursuing my doctorate in Pathology & Cell Biology with a focus on Ovarian Cancer.

[@StephanieButtermore]

What is up guys?! 🤚 It's been a while since I've done the 10K and the response was amazing!! You guys like watching me eat, I like eating.... it was a good time to be had! I tried to make listening to a bunch of numbers and data as fun as possible! Hope you enjoy! Much love!

[@KianteMarron]

I actually want to do the challenge just for gaining weight but as for now I think I'll pass lol

[@UNRULYMARSHA]

Stephanie Buttermore I don't know if it's possible but I would love to see a 10k challenge eating clean

[@jranrodjoe]

Stephanie Buttermore very informative video! the pretty nail paint was 'pretty' distracting throughout the video! :) :)

[@hollypotozny588]

LOL do you know how hard that would be. She's a tank though - I'm sure she could do it haha

[@mirjamoomens3935]

One pound of fat was all it resulted in, in the end... and maybe you would've lost that too, had you not 'splurged' a bit in Ohio. So all in all, you are a perfect example for people to show that no matter how bad their eating habits are now, if you eat healthily, bad blood and body markers may get better quickly. I'm also glad you didn't resort to detox fasting or something like that after the challenge but returned to 'normal' eating. Didn't you have a hard time eating in the days directly following the challenge? Weren't you still full from all that sugar and fat?

[@jessicadevenport5746]

I love how you actually show the science and comparison of the 10k challenge, it makes it more interesting and informative. you are so inspiring!!!

[@StephanieButtermore]

Jessica Devenport really happy you like it! ❤️

[@Brian-bv7ih]

Most girls are straight not bisexual girls are attracted to men not women

[@alexnadon6999]

I have to agree, As i enjoyed watching you eat. It was also very interesting to hear about all the science behind it. Some of the numbers i am not sure what they are. But for the most part I thought it was informative.

[@deannaworley9849]

Booperdoopee most girls like who they like and don't give a fuck

I feel like the 10k calories eating challenges is a really stupid challenge, but I also really like that you did something good with it and actually looked at the science behind it!

[@HeyCosby]

It's always super encouraging to see a woman who is so intelligent be so... idk... KNOWLEDGEABLE in a field that many people deem "useless." I feel like people have this stereotype that people who workout are just meat heads who live and breathe "gym." But people like you, who go against the stereotype, encourages someone like me (currently going to uni for engineering) that I can maintain this lifestyle, even if I feel like I don't have time. Can you maybe do a video about working out and having to go to school at the same time? Like, how you balanced it all? I feel like that'd be super helpful.

[@aznericxD]

must be tough to hit the gym after all that time in the lab

[@JessBieda]

I'm a Sports Med student so I absolutely love that you turned the 10k challenge into a body comp study!! Maybe next time you guys do a food challenge you can relate it to a Wingate test and anaerobic power output! Huge fan, love your channel haha

[@aliciakocher8452]

I truly appreciate your scientific approach! Please keep these types of videos coming!!!

This is by far the most interesting video I have watched all year. Now I realized what's been missing from the froufrou beauty/fitness videos. Research, Data, and Hard Facts!

[@cecy86v]

I want to know how you digestive system handeled all the food? (I know gross probably to some) I think it would be interesting to hear

[@fabricsoftenerfairy]

You said hitting the right combination of sweet/savory was key to being able to make it through the challenge. Very interesting! I remember reading about the right combination of fat, salt, and sugar used by fast food and junk food producers to leave consumers wanting more and never quite feeling satiated, and ultimately this tactic being one of the factors involved in today's obesity rates.

[@TheElenaNumb]

[@sarahcasciato]

hello! I'm currently getting my bachelor's degree in nutritional sciences and I found this video hella interesting, would love to see you put out more science-based food and nutrition videos, helps nutrition nerds have something to watch that isnt your super basic nutrition video!

[@monicawilliams1741]

I love how you and Jeff intertwine science and fitness. These findings can benefit so many people. Keep up the amazing work!

[@virgo4192]

definition of a beauty with a brain! really loved ur 10k videos!

[@abbypollock]

I LOVE this (and you and Jeff)!!!

[@bazza1bc]

I appreciate the science behind this, thank you for doing a follow up. it's great to see the aftermath.

[@hollypotozny588]

I love, love, love how this was part of a study and that you shared all of the data with us! SUPER INTERESTING!!!

[@Danithinks]

I am completelyyyyy mind blown at the amount of information I have learned. You're my new favorite KZbin fitness hero....I can't wait for future videos. Your content is amazing !!!!

[@shesomadeline]

This was sooo informative!!! I always wondered how these 10k eating challenges drastically change someones blood sugar and weight gain as well as heart health. Terrifying! Glad your health is back to normal safe and sound! Its alarmingly scary when other youtubers who do the 10k challenge dont bother pre-regulating their health before this troubling & dangerous 10k challenge. They can easily set themselves up for health problems due to their lack of awareness or care of where their blood levels are.

[@kelsey5139]

do a vegan 10 k challenge and compare the results

[@xxbowsandflowersxx8994]

yess omg that would be super interesting

[@mitmat2140]

10k cal of oreo.lmao

[@ElxM100]

Kelsey Smith 10k will be too much.

[@arthurx333]

Nothing would change for the most part. It would take buckets of broccoli to do that though. Pretty much impossible for most people.

[@JuhQman]

Unless you're eating all nuts and seeds I think it'd be next to impossible to do this with vegetables. If done without nuts and seeds the fat consumption would be rather low and it WOULD be interesting to see the results.

[@MedaPeutics]

WOW thank you for doing this CORRECTLY STEPHANIE! Great science backing on the challenege. This was so awesome!

[@laurenreiner1632]

worth the wait for this...SO informative! thank you for taking the time to do all of this!!

[@jonathanhijlkema8247]

Really interesting, didn't expect the human body to store fat at that rate, pretty scary actually :) A healthy food challenge with a more normal macro breakdown perhaps, just to see if overeating itself does the same as eating a overdose of sugar and fat. Not much fun to be had there though haha

[@oreoorva]

Jonathan Hijlkema K

[@davidmajor1508]

The human body does not gain body fat at that rate. She doesn't know what she is talking about. Extra water stored innthe fat cells can be read as a gain in fat mass. That is what happened here.

[@iron_unicorn]

David Major Agreed, how does someone who eats 1,500 cals/day normally digest food in that quantity and store between 10pm and 7am? She’s weigh more due to partially digested food in the intestines.

[@watchthisheadspace]

David Major looking back on this now no she was correct, her body was being starved which is why it grabbed the fat immediately

[@JackSparrow-dl1cd]

I MUST SAY THIS IS VERY USEFUL INFORMATION AND IT MOTIVATES ME NOT TO EAT IN CALORIE SURPLUS TO LOOSE WEIGHT. YOU JUST CANT CHEAT YOUR BODY.

[@mollynishiacais816]

[@Dr83J]

Stephanie! This is so cool. I love the scientific spin on the challenge. I professionally work with Individuals struggling with eating disorders. I work collaboratively with a nutritionist who specializes in functional medicine and conducts these same measures/tests. It's so fascinating to learn how our internal systems are impacted by our nutrition. Thanks for your vulnerability and openness in sharing this video. Really remarkable stuff!

[@Kimsey_]

Thanks for doing this. I'm sure a lot of us watched countless 10k challenge videos and maybe even thought of trying it without knowing the after math. Very informative, love it!

[@flavia16mt]

Liked before watching. I've been waiting for this video for a long time. Good job, as usual.

[@another.nikhil]

What if you did a 10k calorie challenge on lean food ? Would the results be same?

[@StephanieButtermore]

Nikhil Kumar Ramreddy not sure if the composition would have been different if i stuck to very high protein vs very high carb or very high fat but there is some research indicating the high protein would have been the least detrimental but would have been very hard to to and high carb is less likely to be stored as fast as dietary in an acute feeding but i think there needs to be more research 👍

[@resantic2256]

Nikhil Kumar Ramreddy What is lean food? A calorie is a calorie, in terms of body composition it doesn't matter if you eat healthy or eat McDonalds all day if calories are the same

[@another.nikhil]

Stephanie Buttermore Thanks for the reply. Good job on the video, we can see the amount of effort that you put in.

[@timingmile7030]

ok go to macdonalds and eat your calories total worth of food for a month, everyday and tell me how it goes ^^

[@codysmith6765]

A calorie is a calorie, yes, but things like McDonalds are very high in sodium which can cause a lot of water retention. Also, calories aren't an exact science. There's still a lot we don't know about how the body processes food, but for now, calories are just a good estimate of how it works. I would say eating a low carb/low fat and high protein meal will keep you at least appearing leaner than vice versa.

[@alybreezy]

Holy crap, thank you s much for this. It wasn't just a challenge to get the 10k, but to also inform. I learned so much from this video. I've studied physiology for years but a lot of that came into play in here. It was really nice to see it as a picture and not in the most micro way possible. Thumbs up! 😊

[@SVikusik]

This was the best 10k I ever got to watch because it was so educational! Thank you Stephanie.

[@kzfingerprint]

First time I've seen one of your videos, and I'm totally digging your channel. It's educationally based.

[@fireice1234567]

[@eulaliafebrercoll8249]

Love your videos! I'm a PhD student myself and love seeing how you manage to work out hard while you study. I've been finding it exhausting, since I have to combine it with lectures and an extra job, so working out often falls off my schedule. I'll be looking forward to watching more of your videos! Keep it up!

Very interesting to know the aftermath after a 10k challenge. :)

[@abcw114]

So interesting. Your takeaway is a good one, but I'm also excited about your BMR going up. So many people say refeeds help them lose more, but I was dubious - only because I thought it was a slippery slope. That said, a lot of dieting is known to drop bmr, so strategic refeeds may be an integral part of a successful long-term diet. Years of restriction have slowed my metabolism and I'm still having a difficult time with it. I wish in retrospect that I'd known to do this. 10k is obviously unnecessary, but maybe something more modest would be effective.

[@ZGreen-ml5ed]

YAAYYY!!! I was waiting for my favorite TAMPA Florida youtuber to upload 🤘

[@kiflicaodcokolade]

Hi Stephanie! I would love your "scientific thoughts" about intermittent fasting! Do you think its good for fat loss or is it better to have more frequent, smaller meals per day? I read so many pro's and con's about both that now I am just confused in what's best :D Love your videos, keep up the good work! xx

This is fascinating! Good job, very clearly explained.

[@valtorresch]

I love her attitude and how care free she was during the whole process, like in most of these videos people are complaining throughout the whole thing about how much they're going to gain or how much extra time are they going to have to spend in the gym that week, but she and her boyfriend are just all smiles and I absolutely love that 💖🙌🏼

I've been waiting like, forever for this video and I'm so glad you posted it! Many people beat themselves up after indulging in a slice of cake because they classify it as a "bad food" and think they're going to gain weight, but you're showing us, with evidence, that you won't and you're most likely to gain water weight which isn't as harmful. Great video! I love your nutrition tips and content

[@bangsitsin]

Maybe next time can measure 48hs before, or two weeks before so that your before number can be more accurate considering there's a lot of variables to count.

[@TheBrockwayBabe]

Do you think the 2 week post challenge results would have been different if your food intake and training had been consistent with what you had been doing before the challenge? I find your scientific approach to this very fascinating, I would love to see you do more food challenges!!

[@StephanieButtermore]

Brockway Babe very possible! No way to know for sure but if I kept eating in a deficit I would have lost that pound but I wasn't trying to diet 🙊

[@funkiebutch9690]

I legit checked your channel almost everyday for this video :D. I'd love to see the results of like a raw 10k-challange or a clean one. Just to compare the effects of de novo lipogenese. Those wouldn't be as fun to watch tho as seeing you destroy fun food ^^
