I actually love fasted cardio only because I don’t like the feeling of food in my stomach when I’m working out. I feel sluggish. However, I don’t think there is anything magical about it for fat loss, I just find it more comfortable to do.

Okay idk what you did over the past year but the energy you’re coming with in this video is outstanding and it honestly made me like the video, just for the charisma alone.

If i eat before cardio, even five hours before, I'll start to feel sick and lightheaded. But some people get the same if they are fasted. So yeah, whatever cardio works for YOUR body is the most effective.

I love these type of videos that debunk trends and fads in the fitness comunity using science. Thank you for another great video.

Great video. If it helps people eat fewer calories by narrowing the eating window then it could help. But probably not anything magical about it

I love that you are back and bring everyone awesome videos like this that dig into studies that most of us do not hear about. I have always loved the positive attitude you bring to everything where it boils down to "you do you". Do what works for you but here is what the data says. Use it as you will. Glad you are back again (and have been back for a few videos, but just commenting now).

I was trying for years to lose fat. It was really hard. Intermittent fasting was one of the hardest thing I tried to do in my life. You need so much mental strength to go through day while fasting. I am currently experimenting with NextLevel Diet and it's working perfectly for me. I could recommend it.

Interesting. I do intermittent fasting and have done for 7 years. I do fasted cardio and non fasted cardio, depending on the time of day I train. I do prefer training fasted, but if it doesn't fit in then I don't sweat it. I love IF it helps with not having to worry about food, helps with restricted cals (I like big meals) and helps when maintaining

Love to see videos like the ones you used to make. Great to have you back!

Thank you for the videos as always, PictureFit!

Absolutely in love with each and every video you put out. Makes me so happy and I learn so much!

Man I'm really glad you're back. Your videos have always succeeded to be enjoyable and informative at the same time

Towards the end I had a feeling we were coming up to an "IT DEPENDS" Another good video.

Great job on the video! I loved the humor you put into it along with the usual data 😀

Love the high energy narration and animation since the return

Thank you for the info. Love your videos

Man your videos are freaking awesome!!! 👏👏

No fasting or cardio needed here; this video already has no fat on it. Informative and straight to the point in under 10min. Thanks.

Its amazing. First time I have heard (and it got recommended to me) about fasted cardio in the traditional sense was like 4 years ago. It felt good - I don't know why and it would be cool to know. BUT, it felt amazing. Thing is, I always work out in the morning before work and there I won't eat anything before going to the gym. And having 1-2 cardio mornings in the week I always go there before eating. Afterwards its (not always) a protein shake or a yoghurt with berries and oat. So as for me, I will continue doing this but as long as it doesn't do any harm. Anyways I wanted to thank you for this video and wish you much love

I really trust this guy, most of my knowledge about fitness is from him!

I've always done my morning runs while fasting because I have a weak stomach and always vomit whenever I eat before running. Doesn't matter the portion.

0:30 Greg Doucette I'm looking at you

i need more merch, i bought a shirt from you years ago and its my favorite! It fits so well and the fabric is lovely! i wear it all the time

Your videos are awesome, informative, and entertaining. Great work @Picturefit. Caloric deficit is the MAIN WEIGHT LOSS KEY. Thank you

Thanks for the update on this topic, now where can I get the recipe book and supplements?

Thanks PictureFit! 😊

I'll be checking my doorstep for that protein! I was already subscribed for years though.

Since I'm already doing 16 hour intermittent fasting and I like to workout first thing in the morning, it's just easier for me to do all off my workouts fasted. Also, I feel like it's helped me with waiting until 11 am to eat. My workout performance did suffer a bit from it at first though.

I think it depends more on the goal. For me i use fasted cardio to get faster keto adaptation and also improve my fat oxidation while I run for better peformance in the endurance running, but when I do intervals or very hard session, I do carb up just a little and after the session. PS . Sorry for my bad english.

Very good points, wonder what the influence on muscle protein synthesis would you be to 🥴

great video! thanks

I like how you incorporate humors in your videos 😂

Amazing video!

I kinda love the way that you lean into the whole "I'm trying to sell you Sh**" thing. It's hilarious.

Every new video you post you sound more and more exited for some reason lol

I appreciate that you are back! Are there any plans to make an update on the science regarding Keto? Greetings from Germany.

Great video as usual. But this one comes to show that everyone is different - my performance and overall energy during the day is considerably higher when exercising fasted. I’ve tried all other options: small snack 30min before exercising, a meal a few hours before, the whole lot. Nothing comes close to the performance and energy output I produce when fasting 🤷🏻‍♂️

What I do like about intermittent fasting is the lower hunger levels I just prefer having 1 or 2 meals a day

I do a lot of intermittent fasting. I'm often in a fasted state when I go lift weights and/or do cardio, but that's mostly an artifact of just what time I can schedule doing all these things, and not an attempt necessarily to be fasting during exercise. I will say that the IF has been very effective and changing my whole approach to food, and I can honestly say I never feel hungry or "hangry" during my workouts. Do I take a performance hit by fasting during my exercise? Maybe, but I don't care, I'm not trying to win a medal or anything. It just feels great to exercise, especially after avoiding the gym for so long during the pandemic.

I'm usually doing my workouts fasted, first it was quite easy to me and I limited my eating window as well, but the slimmer I am, the more nauseous I get when working out fasted. I don't wanna feel dizzy and weak during all my workouts, so I guess I'll eat before working out from now on. In the end, we want to feel good and have energy and actually enjoy life and exercise and that's what matters!

You should've made it clearer from the start that there is a difference between fasted cardio and cardio while fasting

So you mean to tell me that the same exercise will burn the same calories no matter if I'm fed or not? And it all depends on the calories I consume throughout the day? Yeah sounds about right

My favorite PicFit video on this topic will always be the first one you uploaded, with the cutaway story of Fit Fiona dumping Big Bob because he gained a few DadBod pounds before DadBod was cool. Shit was hilarious.

Definitely important to also assess why* you’re doing this cardio. Is it for cardiovascular health? Fat loss? Performance? Each of these are going to require different energy-input factors. Not all cardio is the same.

What was the "shake"used in the study please? I wonder if this impacts things e.g. an MCT or BHB based shake vs a glucose shake vs protein?

Can you make a video on how often you should switch up your work out plan

Keep it up :)

Just subbed♥️ Great video, anyone know if there's one on fasted weight training??

I would like this to be researched with people doing the keto diet or carnivore diet.

Commenting for algoo. And amazing viddss!

Great video. As an obese individual that lost well over 100 pounds and my wife lost over 150 as well. If you are in a deep ketogenic state and fast 48 hours with intense cardio. You’ll burn so much fat it’s insane.

I missed you man

Make a video about the benefits of eating vegetables and how much/when to eat them.

I do IF and my eating window is 4 to 6 hours hours in the late afternoon depending on what I'm doing. I work out fasted in the morning because it suits my schedule, it does take a while to get used to it but. I think your right though that it's the fasting doing the havy lifting, not when you do your cardio.

In the US Army, morning PT (physical training) is usually at 6:30am. The on-post dining facility doesn't even start serving breakfast until 7:30am. These hours are for Fort Hood, TX, but are what I remember from my time in the Army from 1996 to 2016. I eat before I do cardio now (as if I need it), but if I need it, how did I do without it for 20 years in the Army?

Well it depends

Can you do a video on the science of fatty acid’s oxidation? 👍👏🙏

Your voice is different from the one used 3 years ago. Who are you and what did you do whit the real PictureFit ? 😏😂

About what I had concluded about fasted cardio when I first heard about it. Only thing I'd note is that some people get nauseous if they eat then exercise, so good to know it's not doing anything bad unless they're going for a marathon or something. I'd be interested to hear about the opposite, though. What the effects are of eating midway through a long workout.

I share you opinion in regard to fasted cardio and weight lost, but something interesting to consider is metabolic flexibility. In my opinion, fasted cardio help you to adapt to fat burning. Also, I thing that fasting cardio help to switch from burning one fuel (Carbs) to the other (Fat), and be more fat adapted during exercise. Just my thought. BTW, great format of your videos!!!

If your goal is muscle preservation, IM is the way to go. Great video 💯

Where is the link to buy the above mentioned whey protein?

2:25 the fact that i got this reference shows how old i am

For me, it's harder to do workout after a meal because I usually feel sleepy after a meal... But I usually eat some meal after my exercise tho' (give or take about 1 to 3 hours after the exercise ended since I also cook my own meal). Well, that was 2 years ago before covid and all. Pandemic got me fatter than I've ever been because I got nothing to do all day and I kinda feel the void with food and youtube videos for these past 2 years (and a lot of video gaming and screaming at people on headphones). I finally decided to clean myself up and get back to my previous shape (because I need to fit in a suit for my graduation). Thank you for your videos, man. It's nice having this kind of interesting video about health and fitness that doesn't bore me to death while also giving me important scientific background to every decision we need to make. Now, let's see if I can cut 20-30kg of fat or probably turn those fats to muscle. Cheers, man!

What people need to understand is that these studies don't control calories so they are very much useless for the knowledgeable gym goer. What I mean exactly: if I decide tomorrow I go on a cut on 2700kcal it is absolutely irrelevant if i do fasted cardio and eat / don't eat after the cardio. Why? Because I'm going to hit my calories regardless of the type of cardio I do, fasted or not, leg day / upper day, sunny / rainy day, you get it. Not eating afterwards would just mean I'm going to stuff myself with more food later in the day and be more uncomfortable, maybe before sleeping. This whole thing of fasted cardio + not eating afterwards may only benefit the noob that just started his fitness journey, doesn't (know how to) track anything and just wants someone to tell him exactly what to do to speed his fat loss in which case you tell him to do fasted cardio and then drink a coffee and not eat till lunch. Of course he's going to lose weight, but if you're tracking and doing a well thought out cut, it's irrelevant and you eat exactly the kcal you set no matter what :)). Besides all this, good video, I actually didn't know about this new study and the whole 'don't eat after fasted cardio', nice animations

Are there any negative effects from doing 30 minutes fasted cardio walking on the treadmill as far as raising cortisol levels and possibly fat storage or lean muscle loss?

Hey picturefit! Love the vids but I have a quick question Rn I am 14 abt to be 15 in a couple of weeks 5’7 and around 72-73kg (mainly fat) I wish to go on a calorie deficit. But my mom is afraid that if I eat less at this age it would stunt my growth since I’m right in the middle of puberty. What’s your take? Should I wait till I’m at the end of my growth? Or is it healthy to go on a regulated deficit?

Watching this after i finished my fasted cardio💀💀

I personally enjoy the feeling of intermittent fasting/fasted workouts when I’m trying to lean out 😅

Love your enthusiasm for the videos man, can you tell how can I be more enthusiastic? Ps: i am a very reserved person :'(

Idk about others but fasted cardio for me works really well. When I have a meal even 3-4 hrs before cardio I get side stitches which makes it really hard for me to keep performing whereas doing cardio in an empty stomach I don't get side stitches until very later into doing cardio. My conclusion is that if I have a meal (Consumed calories) + drop in performance during cardio (Fewer calories burned) < If I don't have a meal (No calories consumed) + Better performance (More calories burned)

3:14 😂 😂 😂 😂 😂

Do what can you take or do to increase your height or get taller?

nice video 👍

Wow thanks

Hmmm, I get it. The data says this, but the way my body has been losing fat has been severely life changing with the fasted cardio. I do cardio for an hour at a moderate pace for 1;05 to 2;10 in the morning on the elliptical and the machine says i burn about 650 to 700 to 1350 to 1400 cal. I go home, take a protien shake which contains 510 calories, and 50 grams of protein followed by 4 scrambled eggs with cheese and black forest ham which gives me about a total of 990 calories. THEN i head to the gym 3 hours later and do a high rep workout that can be about 2 to 3 hours. I then go home, take my protien shake again, then eat two 3 to 4 oz salmon and some spinach or broccoli. Which gives me abouta total of 2100.... Nevermind, its my calorie deficit...isnt it...but my deficit is huge, so thats why I'm losing weight so fast. I hate answering my own question sometimes...

Well,it depends

Does fasted cardio improve wider health markers such as insulin sensitivity, BDNF, autophagy etc

He said it guys, he said it depends !!

I do fasted training in the morning besides a pre workout just because it fits into my schedule better.

"It depends" :D

Have you done a video on the afterburn effect?

How does IF not eating pre training effect muscle loss compared to IF and eating pre workout? Thanks

Endurance athletes do it often during zone 1 (3 zone model - sub LT1) for the performance benefits, rather than to lose weight.

As an amateur endurance cyclist I find this hilarious, I cannot imagine doing a 3 hour training session without any fuel.

It increases AMPK from zone 1, but I don't know if anybody has measured changes in mitochondria or VO2 max.

I does do fasted training in my cycling , having food in your stomach causes your body to use important energy for disgusting. Most of the blood is rush to the mid section instead of the legs. It does work for me for my cycling . But sometimes use it for running too.

does fiber increase your metabolism in regards to fasting

So at the start of the video you talked about people who don't eat before a run burn fat during exercise, but burn carbs after. Where does the carb come from if they didn't eat?

I've never done any kind of like fasted HIIT cardio or Treadmills or Running and such. I have done fasted hiking and that was almost more an exercise in proving out that I could. Like proving to myself that I didn't need to snack to perform tasks and what not.

3:15 No way ! 😳

I am running since last year's November and I lost 20 pounds till now. Acc to me I didn't notice it . Sometimes I do fasted sometime fed. What I have felt , fasted keeps my hunger up. That's why I drink water and I slice of apple. Keep me charged up for 1 hr running . In fasted it becomes a burden. I perform well on fed not too much fed just a slice or 2/3 peice of grapes. 😎

Well, when im fed before workout i always end up feeling like puking, and sometimes actually throwing up lmao.

I did fasted cardio once and it really messed me up. I got bad heart palpitations for some reason (it was so bad I couldn't sleep). (Just FYI I did not eat anything the day before either). So I used doctor Google and it turns out we got these things called electrolytes and me running 10km while fasting the entire day and the day before may have messed things up. So I ate some eggs and chips and drank some milk and the heart palpitation thing stopped. Fasting is not for me lol.

fasted cardio is superior for one reason and thats because it makes my stomach not go blug blug when the food in it jiggles around for 10-30 minutes

When you are doing exercise, you are not generally hungry. So if you wake up and don't eat for four hours, you will have more hunger stress when you are sedentary versus if you spend an hour exercising. During that hour and for some time after you're generally not hungry. That makes adherence easier.

Were the research meta analysis based on RCT's?

i miss Picturefit's "It depends" answer~

In regards to weightlifting I tried going fasted as I was going at 6am… I felt awful and just didn’t have time for a proper meal … started trying out Rice Krispie bars & Pop Tarts.. sessions felt way better and I’m down around 8KG so far …

If you feel hungry right away in the morning, it would be a good habit to get into fasted cardio. Because during and shortly after cardio, your body does not feel that hungry, therefore you can narrow the window of your intermittent fasting a little bit just by doing cardio in the morning.
