During finals week, I used to buckle down and study nonstop, which meant I turned to the most convenient meal options possible--fast food. But whenever I eat fast food, I feel gross. So it got me thinking, does fast food have any impact on my studying and productivity? I decided to experiment for myself to see what a 30-day fast food challenge would do to me.
🙏 Thanks for watching!

Eating like that when you are in your 20s is COMPLETELY different than eating lots of junk in your 50s. In your 50s, all the excesses of youth catch up, decades of toxins built up. In your 50s, you must eat healthy or you’ll end up crippled by cancer, heart disease, or diabetes. In your 20s, a person can eat junk all day, smoke & do drugs. But in your 50s, such behavior must stop or you will end up crippled by sickness.
As you age, the body isn’t superhero strong, so older folks just can’t eat donuts all day. Lots of TH-cam video with young men experimenting with insanely toxic diets. Don’t take your health and youth for granted. 20s bodies and minds need proteins & fats to grow. A super healthy anti heart disease, anti cancer and anti diabetes diet should start in a person’s 30s.

A lot of health influencers pretend that fast food tastes like garbage, but I like how you're honest about it. They're designed to taste good so you would come back. It just makes you feel physically and mentally bad.
taste is subjective
@@allan2665 Whilst taste is subjective it is undeniable that the brain and tongue have evolved to love saturated fats.
nah, i dont think it tastes good, after conditioning myself for years to enjoy eating healthy food i have no desire to eat that and not only does it not taste enjoyable but id never even want to swallow it, id spit it out
edit: if you have some sort of negative response like 'youre lying" youre just admitting youre a coping loser who cant fathom the concept of someone not liking garbage food.. Cope
@@DiaglaTM Yes but most of the fats on a burger or fry for example are polyunsaturated/monounsaturated, it's really only the beef of the burger (fast foods chains like mcdonalds used to fry in lard in the 1950s but now they just use canola,corn,soybean oil)
@@HeirRiddles well thats if you condition yourself like you said. Im talking about naturally liking it. You realize how kids love mcdonalds nuggets and cheeseburgers rather than eating a salad. Because it taste better
I’d love to watch this with a version of homemade fast food-grilled cheese and canned soup, Kraft Mac and cheese, homemade burgers and fries, etc. I would love to see if they cause the same reaction
ive been doing that challenge for years and i can confirm, they do! 🧘♀️
Yeah I cook a lot of food at home, homemade burgers, fries, homemade mozzerella sticks, I can confirm it makes you tired and you will not be able to do anything afterwards
with homemade “fast food”, you’re able to use way better and fresher ingredients. whenever i make a burger, fries, club sandwich, etc at home i feel better
i mean it for sure has less ingredients so it’s a little better but it’s still “ unhealthy” especially eating like that for 30 days for someone who is consider “ healthy” probably gonna have a lot of the same affects
You welcome to make it yourself and post here!!:)
This sounds like the most dangerous and delicious 30 day challenge possible
Nah I would get sick of it after one day
A Dangerously Delicious Diet you say?!
Americans eat like this on the regular that’s why it’s 48% obese
Avg American diet 😂
Only for the first 3 days

Cheap fast and processed foods is all we could afford growing up, and now that I'm an overweight adult trying slim down I still get astounded at trying to solve a current issue that only exists because I was poor. Now that I can afford better foods I am doing my best to get to a healthy weight and it's been working so far even though I still have a long way to go.
preach. it makes me frustrated
If you’re healthy with no problems then industries wont be able to leech off of your money for meds + and also prevent social mobility.
Are you a female?
Try to cut the sugar altogether, processed or not. Best of luck! I lost 100 lb a few years back.
@@bradleyboyer9979 im planning to cut out refined sugar but stick to the low sugar fruits like berries. congratulations on ur weight loss. wish me luck :-)
Another thing about fructose is that when eaten in whole food form, like within fruit, there is fiber to slow down or minimize absorption. So therefore when eating fruit fructose you don’t consume as much :)
Very interesting
Wwwww
@@Aqoticsthat’s literally what he said. It slows down absorption, and because you will be full from eating 2-3 whole fruits vs easily consuming like 12 fruits worth of sugar in a juice, you limit the amount to be absorbed
This is eye opening! I eat a pretty high processed diet and struggle with my energy and brain fog all of the time. I knew something was wrong, but it’s easy to forget just how important diet is.
No it's not easy to forget. Would you shove a Macca's meal into your cars petrol tank because you "forgot" it needs gas?
@@cincin4515That's not comparable at all more like using cheap gas
LOL I learned the veggies then meat then carbs from my friend when we went out for hot pot the first time. I kept going for the noodles right away and she was like no no no you’re going to fill up too fast and can’t enjoy the rest. I never went back after that
Same here. I learned finally McDonalds was bad for you like Seven years Ago.
I thought veggies filled youu up the most ?
Why did you never go back?
@@user-qd3rz7fb1t Oh sorry I phrased that kind of weird. I love hot pot lol I get it when I can. But I meant that I never went back to my original way of eating, I always do veggie > meat > carb now instead of carb > meat > veggie
@@Dee_Dee794 Maybe some people are different but I find that carbs fill me up faster! Because it expands in your stomach (I think)
And yet, I have always been criticized for being such a slow eater! Thank you, I’m gonna continue eating slow; it definitely helps to enjoy the food instead of downing it.
I always never finish my meals.
The second I feel full, food stops feeling good. Even if I'm eating someone's meal, or in a restaurant. I can't force feed myself. And people absolutely hate it.
I wish I could do that. I used to feel so guilty if I didn't finish my food; like I keep eating. Now I'm improving , now I try to eat only what I need and I found out different ways to make use of that unfinished food
This is my problem too, and now in every meal I just cannot finish last too bite no matter what. If I force myself either my stomach hurts or I feel nausea and sometimes I puke. I want to finish my meals but it seems to be difficult.
@@krystal9282 just put less food on your plate alot of people eat with their eyes and bite of more than they can chew, if you're eating out just take the leftovers home and eat it later.
That’s not a bad habit though! That’s extremely good as you’ll probably have a hard time ever getting overweight
@@krystal9282 this isn’t a problem this is healthy
Just started watching your vids yesterday, love the vibe, education, and music choice!
Great video. My masters thesis was on the effects of processed/fast food on learning in adolescents, so your experience reflects the evidence I found. Having a diet of processed/fast food affects your memory and cognitive function by a lot. I’ve always been health conscious and make sure to live a healthy lifestyle for my brain and body. With that said…… Taco Bell is also my favorite fast food and now I want it 🤤
What type of data did you find on how it impacts kids? Pretty dramatic, I assume?
@@bradleyboyer9979 yes, there was an overwhelming amount. Things like the more fast food restaurants there were within a certain radius of a school the lower the average gpas. There were a lot of links between increased weight and asthma. And theres the obvious self esteem issues that affect their success. A huge issue is the food provided to schools being pretty much prison food. The government has been able to claim French fries and pizza as enough vegetable servings because of the tomato sauce in pizza. Come on. It’s been almost ten years since I did my thesis and I’m sure there is even more evidence at this point
@@MiciousDawn It's insane. If my daughter ate the stuff they served at school, she would be sick and morbidly obese. Their breakfasts are typically pancakes with whipped cream and sprinkles. It's absolutely insane.
@@bradleyboyer9979 absolutely. It’s shameful that the wealthiest country in the world is feeding our children so poorly they are malnourished. A lot of the time obese kids are lacking many vital nutrients. It’s also setting up kids’ to have terrible eating habits that will become profoundly difficult for them to undo as adults. Your daughter is lucky she has you to make sure she eats well!
Taco Bell is crack
The mix of lofi and cooking at 13:45 is soo nice! Great video too :D
Type 1 diabetic here. You probably feel tired not only from reactive Hypoglacymia but also from a big jump up of glucose itself. High blood sugar can have really big effect on your concentration too especially if your body is not used to these levels and big change
Do you know the name of the machine used in the video?
@@zarazakithis is super late, but it looks like dexcom!
Nicely done DOC! LOL.. by far the best lesson learned on there.
5:17 It being liquid plays a huge part, I am diabetic and cannot drink sugary sodas as it digests too quickly for insulin to react in time. If I wish to drink something with sugar it must be with a full meal as it delays the digestion of the soda. Also, foods high in fat also make the body more resistant to insulin, so the fats in fast food can cause a problem the same way hence why 2 meals that contain the same carbs, burger vs rice can be processed so differently, as the liver has to also process the fats, this especially affects foods like pizza as it is high in carb and fat. This is actually known as the 'pizza effect' and makes it a very bad food for productivity (and diabetics :)) as it puts you straight into that food coma.
This is really cool to know, I didn’t know about the difference between a burger vs rice for example. I kind of had a preconception that both (since they’re carb) would cause an equal spike (if consumed in the same amounts) so that was really cool to read. You broke it down really well.
@@GingerSpiritSmurf My parents struggle a lot with pizza because it's so unpredictable. Even with the glucose bluetooth meter in their arms providing a graph of their bloodsugar and my mum's ability to have high control over how and when insulin enters her body through an insulin pump, they cannot get pizza down since the spikes appear so random. Which always kind of baffled me since you'd think there's be some consistency in it, even if at first it doesn't act like you expect. They'll occasionally opt to have pizza nowadays but for years my mum refused though my stepdad loves it.
Ive heard way too often high carbs makes you diabetic. Thankfully im not diabetic yet, and been losi g weight for a few months
Its canolia oil and corn oil thats bad. Olive oil is decent but im not a doctor and i suspect a lot of doctors cater to big pharma
You’re diabetic and still want to drink sugar even tho it will kill you?
You should quit eating all carbs slowly and see how that works. Only eat meat.
What a delicious experiment :P
Agree!
Good message in the end. hope you’re doing well after all those fast foods lol
Making slow recovery lol
Well done👏. You'll make an exceptional doctor due to your awareness of good food choices, health & education. Also glad you picked up on the amount of cars in the line up at a unhealthy take away shop. When I eat too much junk food I feel like this and also feel the inflammation throughout my body.
I really really enjoyed this video! Thank you for doing this and explaining things medically and also ‘layman’s terms’ 🙌🏾 I learned a ton 📚
This is the kind of experiments we want to see.
Not just tips and tricks. Actually testing that.
Cheers you Guy!
me sitting in my dorms room, eating mac and cheese, watching this video after a mini mental breakdown. It is home-cooked though.
My exams are over yay now time to watch new vid from Mike and Matty :)
you guys always post great content!
You our new favorite 💯
Isn't this guy the grammarly ad guy?
I've watched plenty of these documentaries and this one is by far the best. Detailed, honest, genuine, funny & informative!
Have you watch "Fat Head"?
I haven't watched this video yet but I'm an uber eats driver and this basically looks like my diet. I'm health conscious and I try to eat "the healtiest options" on the road like been burrito or veggie burrito from taco bell, or the breakfast wrap from sonic. So I'm super interested to see how this plays out.
Meat isnt unhealthy its just bad for the evironment, bean burritos and veggie burritos are not healthy compared to an actual burrito with beef and vegetables and non-fake cheese
Thanks for taking one for the team! haha
this was such a good video! please do more experiment type videos
Thanks many more to come
This was a great experiment.
Thanks for sharing it, I'll show it to my friends.
Haha. If you guys decide to do this, let me know the results!
Very much appreciate the HxH reference. I'm curious as to how beneficial a blood sugar monitor would be while dropping weight.
8:42 the stock parts of the video really helped bring the video to life knowing that koi did it!
The first video with those type of challenges which I learned something useful I am a med student too. Thank you !
As a student, I can say that this made my "Animal nutrition" chapter 10x more interesting
Lollll
I've been on a fast food diet for 6 months. I've lost 75lbs. Each week I pick a restaurant and every day is 1500 calories from that restaurant for the week. I take a daily vitamin, and one day a week I will make some chicken and a salad. That is my "cheat meal". My favorite restaurants are taco bell, domino's, and chik-filet. Pizza weeks are my favorite, as one $8 pizza is enough for two days worth of calories just about. It's actually not that expensive because I haven't bought any groceries in half a year.
Why?
i’m interested in this experiment, but with similar macros in both meals (home-cooked and fast-food). Or at least similar amounts of proteins and calories (carbs and fats are pretty interchangeable).
i like that this video is not 1 hour long ! ;p great work very interesting
I like cooking, seeing how much effort you are putting into your food is really satisfying. Also imagine cooking for my future partner makes me want to practice more cooking. But I also live in dorm which is little bit dirty and have several spiders so I decided to buy bento- japanese supermarket food with salad
You can make salad on your own
I found 12 spiders in my apartment in the 10 minutes after I got home from work, so you have no excuse for not cooking at home. Just meal prep and use air tight containers and you'll have no issue
This is kinda like a click bait. When he said fast food diet, I thought he meant that he would eat nothing but fast foods for 30 days.
I'm going to have to watch this often. We don't eat take out more than once per month but I make food with the wrong carbs at least three times a week.
If I must do fast food, I get Panda Express. I order a meal with brown rice, veggies and a low cal entree like mushroom chicken. Some even have tofu options.
good 4u
The Attack on Titan running in the background 😂👍
great video with switch between junk food and healthy options!
A tip for night shift days: meal prep? Maybe the night before, morning of, weekend or start of the week. Even a simple salad that you can refrigerate. It might be nice to know that you don't have to stress about what to eat/what's for dinner. If you're a sandwich guy there you have it, a sandwich/wrap is pretty good. I'm no expert I just spend too much time on the internet
Thank you this nudge in the right direction!
would be interesting to see how a fast would affect your insulin levels as well
Gotta be honest, now I am interested in how to optimise my meals.
This needs more views. How has this not hit a million?
I also don't feel really good after eating fast food. I was fat before like really really fat. My weight was 90 last year and i am on 65 today. Switched my diet and i lost 5 kgs in one month. I remember that when i weighed myself. From that very day i decided to not even touch fast food and i always take fruits with me during college when everyone is eating some fast food and i eat fruits, oats, rice. And i love it ❤️
I used to eat a lot of ramen before covid, but now after barely eating ramen for two years i finally tried it yesterday and oh my god it felt like drinking battery acid. I thought i was going to vomit
Fast food in Europe (specifically UK) is not cost effective at all, it’s way cheaper to buy your own groceries and cook up a meal.
It is cheaper to buy groceries in the USA too! It's fucking $7 for a cheeseburger. You can buy 1LB of raw meat for less than that. Don't let all our fat, lazy people fool you. Home cooking is MUCH cheaper than fast food.
Remembering the good (?) old days with Jollibee and Mcdonalds literally on the same street as my med school. I gained almost 10kg from all the fast food and stress eating. 😟
I liked watching you cook though (even though I never cook hehe), any recipe/meal plan videos in the future?
Going to do this myself!
Me watching a pizza: Oh it's my lucky day!
Matty: uhhh that's a lot of damage here, that's a lot of damage.....
you cant just look at the glucose, you also have to take in consideration the additional ion concentration created after a breakdown which have to do with how everything communicates
could have compared the fast food and healthy meal by making the macros and calorie count nearly identical because that has so much more of an effect on glucose than whether or not the food was made in a restaurant or your house
What's the control? What was his diet like before this experiment?
This has been the most inciteful video I’ve watched
Thank you!
Watching this is very insightful. While I'm eating McDonalds as I watch.
I read The Diabetes Code and it says the exact same thing you’re saying. Thank you for this video. I’ll keep this in mind when I crave for fast food and will go read a book or study a topic.
This was fun to watch, but it's hard to make conclusions from if you're not tracking macros and calories for each to keep that relatively stable across the two condition
Agreed, this was not meant to be medical advice, just fun experiment with some nutritional education
@@KoiAcademy I know, I was just saying that for an experiment, it's not very scientific haha
Love that aot was running in the background 😂
I wonder how your skin felt during/after this experiment? I was on the road for couple days and we only had fast food. My skin's oil production went thru the roof (I'm female), the texture, the blemishes all were out of control. I cared for my skin the same way as i did before the trip, so I solely blamed the food.
Same! For some reason big fast food restaurants like mcDonalds or KFC make my skin so oily, even tho I have dry to normal skin. I really wonder how that works
@@lulu486 well, there is no nutrients in the fast food meals and the oil it's been fried in has been used soooo many times that there is overall nothing good in it. Except taste (thanks to added chemicals) and crisp.
2 gay women lmao
Great video! Can you link what CGM device you used? I can't seem to find any device you just leave "plugged in" to your arm like that and open an app to check your glucose levels.
This is for the ones who love eating fast food..esp. me.😅 but in the end it has a good message... very nice vlog.👍
Love you’ll
This experiment put things into perspective
This video reminds me how much I hate hearing people chew.
Oops. 😅😬
thumbs up for the ocarina of time lofi
Good stuff thanks
This can show why some people can’t study very well after the slump of fast food.
Thanks for conducting this well thought out and well analyzed experiment! I’ll make sure to avoid fast food, except Chipotle…I can’t stop eating Chipotle 😅
Hold up! Chipotle can be healthy. You just have to be mindful about what you put in your food.
@@brialapoint2608 exactly
The videos you guys make are super great for students and I love em so muchhhh but I just have a small request if you guys could make a video on how to prepare for highly competitive exams as I doing myself and face difficulties on how to keep up with class while completing what's been done before
Dude solid choice with that siracha
I've thought about getting those glucose monitors.. can you still exercise and flex your arms with them? Can you reuse them if you have to remove them?
Watching this while eating Chic, Fil A…..Interesting. So full now. Ready for a nap.
When you do the keto diet you stick to the keto diet for breakfast, lunch, and dinner. Likewise, Whole 30 diet - breakfast, lunch, and dinner. Unfortunately this is a bit click-baity. It is not an ultra processed food diet for 30 days, it’s one ultra-processed meal plus healthy meals. I wanted to watch all of it but the results would not be the same as a true ultra-processed foods diet.
We wouldn’t want to be responsible for the poor lad’s demise.... or flunking out of school!
As a diabetic who uses the freestyle libre(cgm) that you used in this video, what wrap/cover did you put over it?
I have fast food pretty frequently (once or twice every few weeks because I love it) and I don’t really get food comas. Sometimes I do if I eat a lot, but that’s only because my stomach is so god damn full.
Something I want to point out is that fats on their own don't tend to affect blood sugar very much, however pairing fats with decent amounts of sugar will take the spike caused by the sugar and prolong it. This is why the pizza was your worst meal. The glucose from the dough and sauce spiked your blood sugar while the grease made it last much longer. This is why many insulin pumps for Diabetics have settings where insulin can be given at a much slower rate over a longer period of time. The functions were specifically made for foods like pizza.
It would be interesting to compare a home cooked meal like microwave/frozen food to fast food. Who cooks/prepares vegetables and a "balanced" meal at home daily? Expecially when they don't have a dietician guiding them or any background knowledge of balanced healthy meals
Your biggest problem was quantity of food, though. For me, a 1/8 slice of a large pizza with veggie toppings works fine as a small meal. So I just wrap up the rest of the slices individually for the freezer. They warm up great on a little baking stone in the convection oven and last for ages in their frozen cocoon. First I had to convince myself that my brother, who once traumatized me by taking a rare piece of pizzeria pizza from my plate, was hundreds of miles away and not able to come in and steal my pizza.
But slow eating helps also, which had been impossible in childhood either for time constraints or greedy brother who ate three times faster than everybody else and inhaled any potential seconds.
My bet is that you ate your home cooked meals more slowly and in lesser quantities. The volume differences can be deceptive since fast food tends to be very dense regarding various macros and calories so the meals might look of similar volume when they aren’t really comparable. So you really need to use a food tracker to check differences in macros and calories for the different types of home cooked and fast food meals.
This! It was not terribly scientific was it?
But I think that's the point. When you eat fast food you actually eat MORE of It because it's less filling compared to a healthy meal
I like that he admits some of the junk food is gonna taste good
I wish you h ad gotten chipotle. It would be nice to see the results of a seemingly healthy bowl. I made myself a homemade bowl tonight at work with a spinach base, grilled chicken, onion and pepper fajita mix, black beans, light sour cream, and 30g queso blanco salsa. I made guac but forgot it at home >.
any carbs will spike glucose, if he got rice, fajita veggies, etc. in it im sure you’d see a similar spike.
I basically did this same experiment for two weeks and gained 5 lbs.
hats off to you for making that sacrifice! I couldn't eat fast food even once a day, ugh. i'd just be so sick
How many lbs did you gain after the 30 days
Bro I love currents too goated album !
I ate fast food this whole weekend and just feel like shit idk how people eat like this
Kind of off topic, but not really, especially for broke college students, food banks and pantries are always available. It might not be the most delicious, but it can help with that empty feeling in your stomach. For example, one time they gave me a small watermelon, peaches, cabbage, cauliflower, and peach cans. If you don't have anywhere to cook, you can at least eat the peaches, and the peach in the peach cans, you can probably and hopefully afford to buy cottage cheese and combine. We all seem to be broke the last 2 weeks of the semester.
And by "we" I meant my friends and I, back in the days...
So who are you gonna nominate next for this challenge
Before starting the video, i just wanna say I’m on the 6th day of my liquid fast (water, coke zero, and coffee) hopefully trying to hit 1-2 weeks, and this video will be my therapy for not being allowed to stuff my face at the moment.
here's an idea - try incorporating liquids with nutrients like coconut water or real fruit juices :))
So you're starving yourself?
@@bigmansteve1828 i mean, i guess? It’s a combination of a religious/health fast. The longest fast of all time was done in the same way I’m doing my fast, with zero calorie beverages, water, and lots of caffeine lol. Sorry that my post rubbed you the wrong way, my friend. May the Guanyin bless you with the peace you ever-long for.
@@nickole6601 because real fruit juices have sugar and it would literally defeat the entire purpose of a fast lol. Coconut water, although having little calories, still has calories. My goal is to consume 0 calories over the course of 1-2 weeks. It is easy, many have done it. The buddha, Siddhartha Gautama, fasted for 49 days with nothing to drink or eat. If he can do that, then 1-2, maybe even 3 weeks, is nothing.
@@Kuefo I respect your fast and your religious preferences however I would be careful with trying to follow what religious figures have done. Since many religions are passed on by oral or written means it is difficult to separate fact from tall tale. As long as you feel okay I would continue but if you feel ill or weak I would advise to stop and seek a medical professional. Also good luck on the fast, be safe and I hope it brings you happiness! ☮
If I were doing This experiment I’d just be going back and forth from chipotle (vegetarian burrito bowl or burrito)Taco Bell (black bean crunch wrap, bean burritos, any of the veggie options) subway (veggie sandwich or wrap) and maybe Carl’s Jr. every once in a awhile for their impossible burger.
I think there is a way to eat fast food and be healthier than the choices that were shown in this video. Always go for the vegetarian option in my opinion 🖤
But I did enjoy this video! Great work!
Love how you call eating bread leaves and beans healthy lol you are getting zero nutrition. Better off eating the meat
I usually eat home cooked meals and I’ll get fast food 3/4 times in a month. Fast food gets sickening after the 3rd day in a row. but when it comes to homecooked food, I won’t get sick of it even if I make l the same thing every day for a week. I noticed after changing my diet my palate completely changed as well especially with sugar.
If you have the mouth for it or are uber hungry, grab 2 slices of pizza, add your own topping and sandwich it and you now have your own personal Calzone.
For the 9:50 about eating slower, I agree pretty much. However, I believe for my experience (not science) that eating slower helps you to digest food and actually feel full faster, therefore eating less. Like throwing everything in super fast and it has not digest and absorb so it is still not getting the "full" message but slowly will at the right time
I'll preface this by saying I have a few genetic health conditions, that tend to make me an anomaly, but my body reacts the opposite. My labs always show better overall health (lower cholesterol, lower Na, lower glucose, lower A1C, etc) when I've eaten a lot of fast food (and I feel healthier). I also tend to lose weight, whenever I go a period of time eating a diet heavily influenced by fast foods. It's really bizarre. But that's not necessarily a good thing, as I'm about 145 lbs at 5'9" and have a relatively low body fat %.
Both my tall thin exes would have the same problem and my daughter.
You might suffer from some conditions like low cholesterol or certain hormone production that fast food supplements like estrogen.
I recommend using cronometer and actually tracking your nutrient intake for a good overview of your nutrients cuz you might be lacking.
All fast food is not the same either, some are heavy in carbs, others are high in fat and protein while some have more veggies than others. That is something you need to look at as well when trying to figure out.
