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.

This sounds like the most dangerous and delicious 30 day challenge possible

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

"Reading the same sentence over and over again trying to understand what it meant" Wow! Now I know why I always feel lazy during studying! This video literally had all the answers to my laziness! I need to change my diet ASAP!

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.

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 :)

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

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.

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.

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.

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.

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 🤤

The mix of lofi and cooking at 13:45 is soo nice! Great video too :D

Nicely done DOC! LOL.. by far the best lesson learned on there.

What a delicious experiment :P

I really really enjoyed this video! Thank you for doing this and explaining things medically and also ‘layman’s terms’ 🙌🏾 I learned a ton 📚

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

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.

This is the kind of experiments we want to see. Not just tips and tricks. Actually testing that. Cheers you Guy!

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 !

My exams are over yay now time to watch new vid from Mike and Matty :)

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.

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).

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.

This was a great experiment. Thanks for sharing it, I'll show it to my friends.

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

Thanks for taking one for the team! haha

I've watched plenty of these documentaries and this one is by far the best. Detailed, honest, genuine, funny & informative!

you guys always post great content!

Thank you this nudge in the right direction!

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.

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

this was such a good video! please do more experiment type videos

Good message in the end. hope you’re doing well after all those fast foods lol

Isn't this guy the grammarly ad guy?

great video with switch between junk food and healthy options!

i like that this video is not 1 hour long ! ;p great work very interesting

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.

Very much appreciate the HxH reference. I'm curious as to how beneficial a blood sugar monitor would be while dropping weight.

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.

This needs more views. How has this not hit a million?

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?

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

would be interesting to see how a fast would affect your insulin levels as well

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.

This has been the most inciteful video I’ve watched

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

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 ❤️

As a student, I can say that this made my "Animal nutrition" chapter 10x more interesting

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

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

me sitting in my dorms room, eating mac and cheese, watching this video after a mini mental breakdown. It is home-cooked though.

Gotta be honest, now I am interested in how to optimise my meals.

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

Going to do this myself!

This is for the ones who love eating fast food..esp. me.😅 but in the end it has a good message... very nice vlog.👍

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.

This experiment put things into perspective

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.

Dude solid choice with that siracha

Love that aot was running in the background 😂

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

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.

Thank you!

Love you’ll

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.

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

Watching this is very insightful. While I'm eating McDonalds as I watch.

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.

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

The Attack on Titan running in the background 😂👍

Bro I love currents too goated album !

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 😅

As a diabetic who uses the freestyle libre(cgm) that you used in this video, what wrap/cover did you put over it?

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!

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.

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.

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.....

What's the control? What was his diet like before this experiment?

I eat really healthy all the time and each time I “treat” myself regardless if it’s an organic , vegan , or GF food I’ll feel like shit 2 days after that. Start detoxing and immediately feel better cause obviously it’s all coming out.

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.

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?

There is a myth that people who study a lot eats less. What do you guys think

Good stuff thanks

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 >.

I'm so curious to see this experiment with fast food meal VS if you make the same meal at home for example (chicken sandwich from KFC with fries, vs Home Breaded chicken sandwich cooked in oven with fries) I wonder what effect that would have on blood glucose.

12:11 haha you got the Baja Blasts

Bro this doesn't have to do with the topic of the video but the zelda lofi at 13:54 slapped me across the face with a wave of nostalgia

That's flash of pink light in video ..was confusing ?? Was that editing ? Interesting channel.

Really like your approach. You didn’t demonize fast food or shake ppl who eat it, you didn’t glorify homemade food, you just looked at the cause and effect with some nice metrics and science to elaborate on what’s happening on the inside

I like that he admits some of the junk food is gonna taste good

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 %.

Obnoxiously satisfying to watch

Watching this while eating Chic, Fil A…..Interesting. So full now. Ready for a nap.

We really need fast healthy foods that we can make in less than 30 min...i went into diet last year, it worked really well but then i started eating badly after reaching the goal...it was a progressive throwback but yeah...i have the impulse to eat fast food but then i feel really fat and disguisting...i have FF at least 2 times a week but sometimes can go to 3...i live with my mother and she cooks homemade food, that’s not the issue is that she helped me a ton with the meals when going on diet, she made everything for me...and when it was over i was basically screwed...like i need to compress all my diet plans into a single method i can follow...i didn’t forget what habits i had but i don’t know why is so hard for me to start doing it again by myself...have that struggle with other aspects of my life :/

I lost nearly 30 pounds and am still losing more but in these last three days we've been holding cookouts and making a lot of food, naturally I ate some food which completely destroyed my body I currently feel like i'm dying, the items I consumed consisted of 4 cookies 6 mini cupcakes 2 cups of an alcoholic drink 2 burgers 4 small steaks 4 servings of chips 3 cups of soda 1 brownie and a small portion of spaghetti. All I have to say is I never liked chips, cookies, soda and sweets or alcohol but I still consumed them, which led to weight gain, and regret, plus i'm already a depressed person which can result in a bad mixture.
