I tried intermittent fasting for 30 days. 

One of my new year's resolutions this year was to lose weight and I decided to try intermittently fasting. Fast forward to now, 5 months later, I've managed to shed off over 20 pounds. I think my main tips are stay hydrated and keep yourself busy because going 16 hours without eating isn't as easy as it seems

I did this unintentionally during university all the time. It usually ended in me eating an entire large pizza or Costco family-sized penne Alfredo in one sitting. Always felt like I was starving myself just so I could enjoy binge eating. Props to you for being able to stay on schedule. Another great video🤌

I did OMAD (one meal a day) for over a year and lost about 30 pounds. Ate whatever I wanted to during that eating window. It’s saved me so much time fixing food, figuring out what to eat, etc. I do 18:6 now and love it. Losing or maintaining weight, depending on what I eat. Game changer for me!

Thank you for this. This shows and highlights how damaging these talkshows and misinformation is spread in the public. These general sweeping statements exclude the individual experience. These challenges give you the opportunity to examine how you operate in your own life and how and why you want to take on these challenges in the first place. Often changes like these come from a place of frustration, and desperation for something new where diet has failed them. I love your approach stemming from curiosity rather than expecting a 'quick fix' that we all often look for. Keep it up! I look forward to each video and feel inspired to be continue to be curious in my own life.

The last two minutes of this video are the most powerful! Allow grace in this journey of weight loss.

Used intermittent fasting to lose around 18kg. Definitely a great diet but it's true that the sole driving force is the caloric deficit. Quick tip: Drinking a lot of green tea and water during my fast helped reduce my hunger levels so even when I broke my fast I didn't consume as many calories. Hope this helps :)

IF changed my life. I stick to one meal per day. I eat dinner and fast/drink water only until dinner the next day. With calorie counting and OMAD/IF I lost 170 lbs from 350 to 180. It satisfies my desire to eat large volumes and once in a routine it is easy for me to stick to.

Glad that you tried it again and liked it! I think the 16h fast is more normal in general and this way if you forget that you are fasting/get busy you reach the 18h mark. It gives you a bigger window for 2 good meals packed with protein and everything necessary while it allows you to stop a bit later (so you can have a snack after dinner ). There are many different advices out there and I think the worst ones are to always do it, don't give yourself breaks ever (you can take your wedding day off and enjoy it, it won't wreck the planet) or to keep pushing yourself even if you feel weak in the middle of your fast. If you feel bad or unable to keep doing it, take a break and have a snack. Especially for women and our periods we need to listen to our bodies and not force it to fast when we feel like passing out.

We as Muslims it's easy for us because we fast about 30days in every year for 16 or 18 hours and I can tell u the energy we have during our fast is incredible once we get used to it

I have a tendency to do Intermittent intermittent fasting. From what I've learned, everything is really so personal and you have to figure out what is right for you. And what is right for you may also change. That's why it's important to be really in tune with your body and what it needs. There are periods of time when Intermittent fasting and an occasional extended fast feels right, and there are times when I get very clear signals that I need a little bit more than usual. Taking this more intuitive approach to it has been the best thing for me.

I love your videos. Most other channels just lists the things that might or might not help and who knows they even try it. You try everything by yourself and then make a amazing video on it. Hats off !! Keep these coming.

Love the new angle of the video! Super cool that it didn't end up as one-sided content! Thx for u're great content Matt!

Going to start today because of you 💪🏻 keep it up

I have been fasting for about three months now and I lost 22 pounds. I believe Early time restricted fasting is the way to go (you eat during morning/early afternoon and stop eating for the rest of the day. Three tips I can give to whoever is thinking about doing it: -Eat enough protein which will make you feel less hungry throughout the day; -Drink enough water (2,5L per day on my case) - Keep your health in check: get vitamin deficiency tested and supplement what is missing;

Looking forward to the circadian fast, thank you for keeping it real and being transparent about changing your opinion on intermittent fasting.

Big fan of your videos for the past couple of years, you always amaze us with great content & quality. Keep up your great work👏🏼

Great principles behind IF - of course, it doesn't work well for everyone to be super specific (16:8 etc.).. I especially liked the reminder that food is readily available in our country and late night snacking has become a norm (or as Bryan Johnson says, self destructive behaviours are a norm). For me, I personally saw hormonal imbalance and digestive issues with 8 months of intermittent fasting. Only last week did I go back to eating breakfast at 8am and finish eating at 7pm - my body IMMEDIATELY shifted. Regular 💩movement at 8am, higher energy levels, honestly just intuitively eating when my body says it's time. The 7pm stop time is helpful to improve deep sleep AND I get the benefit of fasting from 7pm until 8am the next day.

Like you mentioned, it's personal preference and how it works for you. I've tried Intermittent fasting and I just couldn't even train. Started eating 4 or 6 times a day, and I've never felt better, less tired and way stronger. We're all different and things work differently. Great vid!

Geez, it's been a year since I watched your videos last. But I been fasting for on and off for a year now. I have found I genuinely enjoy the feeling of my stomach being empty, In a healthy way, I still love food. I feel as though my food tastes better and my energy is higher than if I eat through the day. My bf decided to try it with me a few days ago. Thank you, I do enjoy your videos

I’ve been looking at your channel for exactly this, it’s crazy you posted exactly what I was looking for from you today!!

After trying intuitive eating, I've found that my body naturally wants to wait about 12 hours between dinner and breakfast. I sleep for 8 hours every night and, to feel my best, I wait at least 3 hours between eating and going to sleep. I take some medication in the morning, for a chronic illness I have, and I have to take it on an empty stomach and wait a minimum of 30 minutes from taking the medication until I intake anything other than water. This comes out to a very natural 12/12 eating window and after accepting and working with it, I've felt so much better. I've lost some weight too, but that was never really the goal, it just happened.

I kept *wanting* to try IF but I was too worried that it would be a struggle. My only regret now (10 months of 16/8) is that I did not try it long ago. It was maybe three days of difficult, then it felt like the most obvious, natural, healthy thing and I barely had to think about it let alone struggle. That said, I *think* the reason it has been so easy is that we (husband and I are doing it together) initially did keto at the same time, which seriously knocked out hunger issues. Now, we have both transitioned out of strict keto but are keeping a still low(ish) carb diet, or at least a No Big Glucose Spikes diet, and we both feel certain that we’ll be on the “easy IF” (16/8) for life. It just makes my body and brain feel so much better. We both lost 25 pounds and it stayed off. It’s taken some effort to get my adult kids (who live nearby) to understand that any “special dinners” should happen early, but if we end up eating late, no big deal 💁‍♀️… we just have a later fast-break. Agree with the key of staying hydrated though. It’s a surprise how much I can go from woozy/weak to feeling energetic by drinking, though sometimes water alone isn’t enough and I add electrolytes (without glucose).

As always a treat to watch your videos Mat, whatever you are doing them on 🎉

Just completed your course on How to Master RU-vid, now I am more connected to you, loved your course and your personality in the videos.

Staying hydrated is essential for me to maintain my intermittent fasting routine.

“If you’re like me, you’re probably thinking; ‘What the fuck?! Does it work or not?!’”. That part got me pretty good 😂 I figure whatever is the path of least resistance for you and can help you keep making consistent(key word) healthy choices is the best way of doing things. Whatever makes it easier to achieve your goals, do that thing.

Really nice and informative video! I just realized that a friend and I are both subscribed to you and we are both huge fan of the quality of your content 😊 I hope you never change, or rather, I hope you stay on the path you've been for years since I started following you 🙌

We appreciate your content. It gives us a whole different perspective on things. God bless you.

Calorie counting and getting good nutrition are also important in one’s weight loss journey’s success. It also might be more beneficial to skip dinner rather than breakfast, since it allows for more energy during the active part of our day, and sets for better rest during nighttime

I think it is an amazing way to control appetite more than a sustainable way to live but I bet it depends on the life style of the person trying it. Great job! Like always! ❤

Love the canva sponsorship. I'm in no way a graphic designer, yet I've made so many projects for school/relationship/family easily using it! Glad to see them sponsoring my favorite RU-vidr!

Hey Matt, Brilliant job on The Minimalists documentary. Well done, great video.

Thanks for another interesting video! Watching what you ate during this video, I wondered: have you ever considered to try a 30 day experiment on eating whole food plant based? I think that could be very beneficial for your health as well!

I’ve been doing a 12 hour fast for years now and it’s so ideal. I’m a night eater and don’t usually eat until 10-11am so I’ve successfully scheduled the late night munchies lol love that you tried this and loved it too!!

This is all good info bro, thanks Matt! 💯💯

Loved the video! I appreciate the non bias take on it!

Success seems to be connected with action. Successful people keep moving. They make Mistake but they don’t quit... As the economic crisis keep rising, we literally need to have different streams of income. The crypto and stock market has plenty opportunities to earn a decent Payouts with the right skills and proper Understanding of how the market works.

I do 16:8 fasting. I eat two big meals a day. It will be about a year now. It's working for me and I found I have more energy, I can do training every day. I did not notice a big change in the weight (I lost maybe 1 kg but I also gained muscles).

love binge watching this guy, hes informative and really funny😆

Great video! Learned a lot more about IF than I thought I would

Thank you so much for talking about this (very) controversial subject ! I don't think intermittent fasting is necessarily bad but for people with previous or current ED like myself it can do more harm than good because waiting to be extremely hungry can cause binges. I did intermittent fasting for 3 years but I feel so much better now that I stopped and eat 3 meals a day. I used to feel so tired during the afternoon but now my energy levels are more stable throughout the day.

Thanks Matt for sharing.I am counting calories but I never tried fasting. Now I want to try this for myself!! 🍲

I liked this honest review. Thanks!

Great content as always. Jealous of that cafe stop!

I fast for 20 hours a day. I run about 3.1 miles a day and do weight lifting. I have lost 50lbs in almost 3 months.

I've been fasting two months (18/6) and haven't seen drop of energy and I don't drink coffee , but also haven't drop weigh maybe 1 or 2 kg and my goal is 5 kgs ( I'm 87 now) . this month i've started running and done 40 kilometers so far.

I also tried it before and failed admirably. I love the Zero app, it's so simple and helpful. Thanks for changing my life for the better. Again.

Great video, great opinion! I want more videos about the topic =) Thanks for hsaring Matt

I started doing IF back in 2021 not because of any weight-loss, but because I'd (properly) made a point to learn all about what the natural processes are for the body, when it's not eating, and also what the benefits were to the processes that occur when we sleep, and how they're improved by again, not digesting. I've never treated IF like a diet, and never will, and only do 12-14 hours of fasting. But I can say, from my own experience, that the noticeable benefits (never mind what's going on that I can't see) are pretty striking. From better sleep to less lethargy during the day, to less inflammation (noticeable as overall body swelling has gone down), to fat that I apparently had on the back of my neck (like what?) that's now gone, to my eyes being clearer. I will say that to get the most benefit from it, we really need to make sure we're eating properly most of the time, which honestly should be a priority anyway. If you're eating 4 big mac meal deals per day, during your 8-12 hour eating window, you're still going to be doing a lot of damage to your body. And the opposite is also true, particularly if your eating window is very short--you MUST get in the proper amount of food, especially protein, or else you're on the road to permanent metabolic damage, which you REALLY don't want. I could never do less than a 10-hour eating window, because I can't possibly eat enough (mostly) nutritious food in less time.

ive lost around 15kg or 33 pounds from fasting over the span of 2 years. At first i didn't workout or exercise so the fasting only was as effective as limiting my calories, but when i started to exercise a 1 year back thats when i started to see results. Intermittent fasting has genuinely changed my life and my 2 year anniversary is coming up soon. Its important to have a healthy lifestyle and always balance everything from your diet to exercise but don't be too harsh on yourself.

Great video as always! Educates on the topic and also reminds me how much I hate daytime TV cringefest.

Love your videos as usual! The idea of also incorporating intermittent fasting into your life as a muslim (not just ramadan) is also advisable. Fasting every Monday and Thursday as well as the 13, 14, and 15th of every month, etc. I'm not entirely sure if you can link this to having any specific health benefits, but it is a spiritual practice.

Matt is basically our “try” our test subject for all things humans should do or not do lol let’s go Matt! Keep on making these dope videos 🎉

I started 16:8 fasting a week ago… The best thing I've noticed is that I am more grateful and conscious about the food I eat.

Hi Matt! Great video as always, and I would like to suggest another topic which needs a deep-dive - creatine benefits.

I believe that when taking a look at the studies for and against intermittent fasting, it is beneficial to look at who is sponsoring the study to see if there are any conflicts of interest. Conflicts of interest can sometimes sway the outcomes of certain studies. It is also worth a look into the benefits of autophagy in regards to fasting vs the benefits of caloric restriction.

Hi Matt, my name is Selvyn and I am a great fan of your channel, and I think it's the first time I am writing a comment 😅 I have been doing intermittent fasting since April 2021 and I have actually gained lots of health benefits, including a significant fat loss. If you have the time and are interested, I would be more than happy to share my fasting experience with you and I would be so glad to have a nice chat with you as well. Keep up with the nice videos and amazing content!!

I start eating at 10am and stop at 6pm. Took a week or so to get used to it but combined with regular exercise and the right foods I feel pretty amazing and full of energy everyday.

Hey Matt, great video as usual. I really enjoy these types of challenges. I have a suggestion for a next challenge you could undertake. What do you think about trying to stop watching the news for 30 days? We live in a world that is now inundated with information. It could be interesting to see what happens if we try to eliminate it completely for a month.

Thank you for recommending the Zero app - that's what I was looking for. I really have high hopes for it.

As muslam ☪️ , we have one month on the year we do that , called ramadan , where we fast from the Fajr ( just before the sun rise) up to Maghreb ( when the sunset 🌇)

You're the best and hardworker 👌💪💪

Great video sir and actually closely related to the research as well.

I love your videos, great content and edition :)

*Matt's 30 day vids are always class, cheers mate on another good vid!*

I'm glad to hear you are also having trouble nailing down solid info. Because of the conflicting information, I am doing a keto/fasting diet. While I know it's not necessarily the best practice, I am eating only once in a 24 hr period. When I break fast, I am eating healthy fats like guacamole, salads with olive oil, salmon, beef, cheese, eggs, or other keto friendly options. I allow myself two cups of coffee and all the lemon water I want. Here is where I went off the rails. I stay up very late, so my fast break is at 0000 hours which I am sure isn't great. That being said I stay up until 0500 hours and then don't again until midnight. So far, I feel great, I find myself less hungry during the day.

Thanks for the video. I am researching intermittent fasting. Im a complete newbie. All positive feedback so far. I appreciate thr calorie deficite of one meal and allowing my body to process and digest. Definately going to give this a shot.

I fast 16-20 hours every day and have been for 3 years now. From time to time I will do the odd 24-48 hour fast. I love it! It doesn't take long to get used to. I tend to train in the evening after eating so I use the glucose from my food as energy. I still get plenty of protein through my food and 1 protein shake per workout. Thanks for doing it again Matt and well done on sticking to it this time!!! I too don't get energy dips in the day. I used to get them when I had the usual 3 meals a day 😮💪

I have been doing it for some months now and i realized that at some point my stomach knew it wouldn’t get food in the morning so my body got used to it after some weeks :) Also helped me at the gym (of course u need to get your proteins in the rest of the time!!) definitely recommendable!

Yes, please do a video on circadian fasting. As a mom of 4 girls, 40, a spouse who is an RN, I don't have free time to work out...yet. Fasting almost comes the easiest.

Literally just watched your first video from a few years agonand now seeing this LOL! I just started fasting this week.

I’ve been doing this lately and I find it to be quite useful.

Great video. Super informative and funny. Good job

really talented youtuber. everything you are doing is interesting.

Yo Matt, I think you should’ve tried the ramadhan fasting next year together with moslem and include it in your 30 day challenge video. Curious how your perspective around it and would love to hear out what your views on it! Cheers!

I was unknowingly intermittently fasting for years, just because of when I got hungry. In my teens mom used to get so mad at me for not eating breakfast (even though she didn't either lol), but I just wasn't hungry in the morning. And I still don't get hungry in the morning, so I only eat lunch and dinner. I feel fine and I'm healthy, according to my doc, so why change? Different things work for different ppl, so I'm glad I've found what works for me

Great video Matt 👍

Matt you should look into caffeine intake. Andrew Huberman recently shared some interesting info on this. Because I like a little cream in my coffee, when I started intermittent fasting I had to delay my morning coffee until 11 am. I found no issues at all with energy fall-off during the day and Huberman's info might explain why.

As a Muslim i am following this routine for past 14 years ! i use to fast about 29-30-day in every year for 18 hours! and this is highly productive and has tons of benefits -health and spiritually both!

I just did a 24-hour intermittent fasting day and thought this would be super hard, but in the end it was kinda nice. Now I'm thinking about adding one or two days a week of 24-hour intermittent fasting. It's good to challenge ourselves and not have to be thinking about food all day.

Cool to see Peter Attia here! Reading his book rn

I’ve been enjoying fasting since Christmas ‘22. Lost weight, better sleep and digestion. I can’t recommend it more.

I did this for a while somewhat unintentionally because I just didn’t get hungry until around 11am, and at that point it just made sense to wait til lunch to eat. Idk what changed over time, but now I get so hungry within an hour of getting up, and I just don’t think I would be able to do IF comfortably anymore.

Muslims do this every year! 30 days of intermittent fasting.

Really nice to hear Peter’s perspective, a nice reminder amongst all the hardcore go hungry and earn food approach. I feel like there is a lot of lean people trying intermittent fasting potentially with eds and I don’t think that’s healthy, I agree caloric intake is the main issue and protein intake

I do OMAD and water fasting, best thing ever. It allowed me to get rid of food addictions, develop healthier eating habits/choices and stop emotional eating. My body feels more rested and my sleep is great.

I think one of the things that people miss when talking or practicing about IF is your mental health. If you had a history of mental illness or if you're dealing with one IF may cause more harm than good. It turned out to be detrimental to my mental health and it felt I was developing an eating disorder with the cycle of starving and then binge eating. It furthermore fueled my anxiety. So now I am back to 3-4 meals a day at equal intervals throughout the day. It keeps me sane.

Who else is into productivity because of Matt ? ☺️☺️☺️👏🏾👏🏾🔥🔥 quality is just super ❤

For me the factor if having to plan and think about my meals leads to me making better choices, its not the hormonal benefits etc but its the thinking about the meals

YEAH! These are the kinds of videos i like!

If you try intermittent fasting again, maybe try drinking water as your first beverage in the morning? I know we're all different, but it has helped me tremendously on not relying coffee and has helped me not drink as much coffee throughout the day.

Have been experimenting w/ IF for two months, and have lost 27 lbs. Have about 33 lbs to go. Currently, I exercise 5 days/wk (3 gym days, 2 very light walking days, and 2 days off during fasting. I fast once/wk from Wed night to Fri afternoon (42 hrs). I’m roughly losing 1.5 lbs/wk now, and building muscle in the process; so… I’m gaining muscle and losing fat, which is my goal. When i hit my target weight, i’ll likely have to change things up with the diet. The fasting naturally increases testosterone, growth hormone and reduces inflammation. I have a 42g recovery drink 5 days/wk after workouts, a keto lunch, then i “cheat” at dinner and eat more of what i want, tracking carbs to keep these low overall (50-75 g daily carbs). Cut out sugars, keep carbs low, no processed food, no alcohol, no vegetable oil (just avocado and coconut oils), eat a higher fat / low carb diet, exercise and watch things improve! IMO many folks are addicted to sugar, and will not admit this. I still have 9 g of sugar/day with my recovery drink 5 days/wk, yet have drawn the line with this amount of sugar. I just like how much protein i can get from the drink. Hope this helps someone!

Loved this!❤

que genial, eres el mejor Matt!

This is just a one person experience but I did intermittent fasting (20:4) for 8 months, lost 40lbs … however I also got gallstones (many small ones which means they developed within months) and had to have surgery to remove my gallbladder. Eating nothing and then a lot in a few hours is very likely to be the cause since I was under 20 at the tome.

We love that Zero could help guide you in your IF journey - congrats on your 30-day 18:6 streak! 🔥Can't wait to hear more about your ongoing year of fasting.

I'm currently doing the 16:8... What I get during my fasting window: water, electrolytes. You can also have black coffee and unsweeted tea. And break the fast with a high protein meal. :) Helps you snack less.

I'm a small petite woman. Intermittent fasting took me a while to get off of the typical 3-meal SAD (standard american diet), especially after having deal with a screwed up sleep/work-schedule for most of my life. Nowadays, 2 main meals and coffee/fasting-drink throughout the day is more than enough for me. Keeping track of my productivity levels is also important.

I never imagined I would be able to fast. Did the keto thing two years and fasted 90% of the time. No longer do keto but it did help me drop 80lbs and made me change my ways. Full fat(avocados, nuts) kept me full and to this day I still fast and have maintained that weight off. Processed food messes with your mind

This is the best thing I've ever tried and I'm not even finding it hard. I'm doing a 18 hour fast and a 6 hour eating window. My eating window starts at 12pm and ends at 6pm. I start off with a smaller meal at 12pm at around 600-700 calories. I have a light fruit snack/nuts/seeds at around 3pm (around 200-400 calories) and then finish off with a bigger meal just before 6pm (700-900 calories). I try to get at least 30 minute workout about an hour before my first meal. In the evening I go for a 30 minute walk. I sleep around midnight and wake up at 7-8am. Drink lots of water! It's been a few weeks now since I started this due to my health issues. I'm 5 ft 9 and weighed 244 lbs on day 1. Now I weight 233 lbs which is a total loss of 11 lbs in about 3 weeks. I'm sure the weight loss will slow down later but it's working out great for me so far. I'd like to lose about 1-2 lbs a week for the rest of the year. My breathing seems easier and I'm sleeping better.
