I Tried Out Intermittent Fasting for 7 Days 

I've gained such a greater appreciation for health and fitness since finding your channel. You're definitely my inspiration. I wish I could train with you.

I've been doing IF for several months now and love how it makes it easier to keep my snacking under control. So glad to get a video from you on this topic! I do a 16/8 split from 12pm-8pm. Keeps my social life normal

Something really interesting to look into is the correlation between fasting and mitochondrial biogenesis! I would never be able to keep up intermittent fasting long term as my schedule and life doesn't really allow it (I work a physical labor job and love the gym, so ya girl needs the cals), but I have found a major improvement in my digestion and overall clarity over the long run by just doing a 12/12 schedule (12 hours eating, 12 hours "fasting" - although it doesn't feel like fasting because the eating period is so big). I don't know if the culture surrounding IF necessarily vouches for this in particular, but allowing time for your body to get into rest and digest mode is something we often don't pay attention to. Thanks for always being so unbiased and educational, I always love watching your videos and feel like I've come away more educated and not so much like a RU-vid zombie.

Yes please for the science! I'm always recommending your channel (including to my Dad today) because I just love your scientific and healthy attitude to living your healthiest life ❤

Yes!!! Please make a science explained video

Yay! Thank you for doing this video! I think this depends on the person and lifestyle. It’s been 3 months for me and so far it’s been ok, i do mostly 16:8, but sometimes it’ll be a 14:10 or 18:6.

How did you go about explaining you were not having dinner to Mario's mum? Having an Indian mum and a Spanish dad I fully understand how not eating is taken as a personal offense haha Great video as always! ❤

you tricked me into watching a vlog and i'm very ok with it

For anyone who want to do IF I highly recommend to consult with gastroenterologist before doing it. If you have any problems with digestive system like gastritis, stomach ulcers, cholestasia it can made things worse. The best plan for your stomach health will always be eating small portions often so that the intervals between each food consumption will be less than 7hours. Sorry for my bad English, it's not my native.

You are so great!💞 I am absolutely in love with your videos, because you are so natural and joyful! I would adore to see scientific side of intermittent fasting!💗 Kisses from Poland 🇵🇱 🌸

Hey sweety, great video 👍 Where is the legging from you wore in the second training (about 13:06)? Is it squatproof? Thank you in advanced. Have a nice day 😊

Hey my friends! Don’t forget to leave a thumbs up if you’re interested in what the science says on IF for fat loss and your health! 🔬😍 Thank you for always sharing so much love to me and everyone else here ❤️

I feel like having the window between 10am and 6pm is not the best, as it's kinda in between everything. I'm doing 12pm to 8pm and that works better for me, especially because I have a more typical office job, so the morning really flies by and lunch is here. I love the content that you're putting out, it really shows your effort. definitely wanna see the science explained version of this!

OMG if I told my Italian fam I didn't want to eat 😅😂#relatable

I've never come across a channel that's more informative, fun, and all around exciting to watch! You give me so much inspiration to spread a positive message on my RU-vid channel all about mental, and physical health!

I could never finish a work out without having breakfast first. I tried to run before breakfast once and I've never felt weaker lol. It really isn't for me. Too restricting for my taste. Does not go well with my body insecurities and eating disorder habits.

*I'm only 2 minutes in but* thank you thank you for separating anecdotal, observational information from the peer-reviewed, evidence-based literature. There is a big difference and how people interpret the conclusions from those two types of information (shoudl be!) different. My little science-geek heart appreciates you !

I've been doing intermittent fasting for 5 months now and have found that it is easier to skip breakfast altogether rather than just trying to jam 3 meals into a short window. I'd recommend anyone doing IF, start eating later in the day than 10AM. Also, don't be so strict about the start and end times. If you have a late dinner planned one day, start eating later in the day. You don't have to eat in the same time window every day.

Yasssss Science 🧪 explained Video 🥵✨🤘🏼pleaaaaaasssss ( maybe also impacts on fat loss) U are gorgeous and I trust the videos of yours ♥️✨🙆🏼‍♀️

Natacha you should have done the 12-8pm eating window!! Much easier.

I’ve been doing IF for about ten years now, without realizing what it was until it became “popular”. I stopped having breakfast when I was about 19 because I just didn’t feel hungry in the morning and I quickly realized my body responded very well to it, I used to feel bloated and lethargic when I had breakfast and since I was not hungry anyway and was just eating because that’s what you’re “supposed to do” I decided to start skipping breakfast and see how I felt. It worked wonders for me, I feel like my body was not happy being forced to digest food so early in the day and giving it a few hours to wake up and get going really helped with my digestion and energy levels!

Natacha! I know you haven’t hit your goal for 25k on this video, but I want you to know that I REALLY would love to see a science explained video!!!!!

You don’t need it to be so strict, you should be more flexible with the hours, don’t necessarily have to do 10-6 can push back and do 12-8 if you have a meeting or do 9-5 if you want to eat earlier. Even a 10-12 eating window has been shown to produce same benefits in the research!

oh my god you are a constant inspiration to me to work on myself!!! big love to you from the notification squad hahaha

I can hardly wait to see you do the Marine Physical Fitness Test 😍 It was incredible to watch you do the last physical fitness test. You fight HARD! Your intensity is quite incredible tbh

Natacha, can you do a sneaker collection? Also, I can't remember if you've done a video like this before but one where you show us your favorite leggings/sports bras/tops to workout in? Thanks! Love the content!!

YES PLEASE do a science explained on intermittent fasting!

Im so happy you made a video about this... IF really works for me, finally I feel more in control and meals are satisfying as Im not spreading calories across whole day

But but but... we always loved seeing those delicious looking breakfasts you always make. Lol! In all seriousness though, have to say, absolutely love the way you combine solid information and fun into each video. We try to take a similar approach ourselves, but there are very few fitness RU-vidrs out there who have mastered it as well as you. Keep up the great content! :)

Your videos are helping me transform my body and health. I suffer from very severe fibromyalgia , epilepsy and Potts syndrome and through your home programme and videos I have literally gone from bedridden to off many medications and working out 6 days a weeks in two months. Thank you for your videos and being such an inspiration 💗

my heart exploded when you asked mario if he enjoyed his breakfast and he apologized and felt bad for having it in front of you

I personally love intermittent fasting because I'm very flexible with it. I do any eating window I feel like depending on the day.

My own experience with intermittent fasting is that it cured my chronic abdominal pain!! Same thing happened with my mum. I always recommend people give it a go and I really enjoyed your thoughts and views on it! Thanks for sharing!!

Hey Natacha, what sneakers do you recommend for the gym, need a new pair and trust your recommendation.

Finally, it's nice and so fresh to see someone with a different perspective and opinion on Intermittent Fasting! Everyone is just jumping on the bandwagon without actually asking themselves if it is working for them. Loved this video. Thank you, Natacha for keeping it so real, raw and honest.

During the times everyone was telling that skipping breakfast is a no-go , I‘ve always forced myself to eat, so IF was really a relief to me ☺️ Although as also having a very non-routine-lifestyle, I think an eating period from 10am-6pm wouldn‘t fit me either. I prefer something like 1pm-9pm. Work starts at 7am and on weekends, I also workout in the morning - and I even have more energy without breakfast ☺️💪🏼 So I think it‘s really different for everyone :)

For me, IF only ever worked short term (tried it several times). My body always caught on pretty quickly and ‚made‘ me eat more later in the day. I would even get cravings and overeat after a while...I‘ve heard, that it can seriously mess with your leptin regulation, if you do it longterm, especially as a women. Would love your opinion on that...there’s science‘ on that topic, but I‘m not the best at figuring all that out...I just heard about it in podcasts and such. It sure seems to work for a lot of people, but I rather stick to having a protein/fat rich breakfast.

Had no idea that I’ve actually been doing IF for 2 years.. I eat lunch at 12 and dinner at 6 so have unknowingly been doing an 18 hour fast... (I don’t eat breakfast)

natacha after 2 years of being interested in fitness and following so many fitspo you are stil geniously my favourite girl!!Best body,personality, badass to the gym and so kind!!

Intermittent fasting cured my insomnia. I was able to sleep 6-8 hours a day. The first week is the hardest the sugar withdrawal is real. I do 18:6 or 16:8 sometimes 20:4... lose 2 kg in two weeks i am walking 30 mins to 1 hour a day. I am 20kg overweight. Calorie intake is 1200-1400.

Mostly playing pool and looking for shoes? I'm still waiting on the IF. Not her best.

Thank you so much for sharing! I love how you show that IF isn't for everyone and that's okay. I personally follow IF loosely and eat two really large meals a day - without worrying about the timing - and this works awesome for my digestion and energy. Again, all about finding what works best for you and your body

The title of the video broke my heart, god what do i hate youtube nowday' s fasting here fasting there, thank god the summary made up for it all!

I much prefer to do 11-7 or 12-8. It is pretty rare for someone to suggest going out for breakfast and morning snacking is easier to avoid.

I love thiss!! Can you make a video on how you balanced university, training, relationships and home life? Because I'm definitely struggling ❤️❤️

After years of experimenting with different intermittent fasting timings, I've found that an 'early time restricted' eating window seems to work best for me. It aligns with our circadian rhythm and I think, that from a biological perspective this could also be a better match with the cycling female body. The cortisol spike in the morning is not prolonged by postponing breakfast, which is important, as increased cortisol can create problems for the female endocrine system. Then, during the day the body is being fed all it needs between 3 nourishing meals and then from this fed (/'safe') state the eating window can be closed around say 6 or 7 pm. If breakfast the following morning is between 7 and 9 that gives 12-14 hours of fasting. An occasional longer fast can easily be achieved by skipping dinner every so often if desired (just not in the week before the period starts as progesterone is easily disregulated by stress). Bonus is that going to bed with a relatively empty stomach is might do wonders for sleep ☺️

IF is natural for me every day. Find a schedule that works for you

Ofcourse we want to see a scientific video. You're literally the best. I love you so much

Great video! Your 10am-6pm window is kinda difficult with your busy schedule. I made my eating window 12pm-8pm. Can fit usually lunch and dinner but skip breakfast.

I was having such a shit morning, with no desire to work out what so ever. Your energy is really catching and got me going anyway. Thank you for that.

girl I JUST started an intermittent fast and of course my favorite RU-vidd comes out with a video pertaining to that not 24hrs later. Excited to watch, love! ❤️

*I love how light hearted you are with Mario, I know that without a sense of humour I would've been super duper stressed and pissed off at myself.* Can you tell us how you manage to laugh at yourself and not take life so seriously?

Ooo that workout from day 1 looked like such a banger! Would you mind sharing it? Amazingly produced video, as always! xoxo💕

It makes me sad this didn’t hit 25 k likes!!! I’d love to see a science based video, but I know Natacha works soooo hard to make those!

I stumbled across your channel yesterday and I've been binge watching a ton of your videos! You're the beauty AND the beast when it comes to training! Love you're energy and your outlook on life in general! Keep up the good work and thank you for the meaningful content! ❤

I’ve been doing IF for a couple of years now and I love it. As a scientist I’ve read the literature and I’m very convinced of the benefits, I really hope you do a video on it! Furthermore it works really well for my lifestyle! I vary from 16/8 to 20/4 depending on the day. I will say it takes a month or so to really adjust. I would recommend pushing your breakfast time back by 30 min every week until you get to the full 16/8.

Well that’s gonna be an interesting video😂 I’m excited to see The Queen Of Breakfasts👑 try IF😃 love you❤️💗

"Do you have a scrunchie on your head and on your wrist?" omg relatable

I wish you had a podcast to discuss all this! I love your info so much

I've been waiting for this!!! Can't imagine you missing breakfast OR dinner haha. I tried this once but I didn't feel a difference, except for being sad I couldn't eat at all times. In the end, it still depends on your overall intake, not just the time.

Anyone else thinks she kinda looks like Ashley ?? (tana mongooses friend)

When i do IF i always do 12 - 20 window. A little bit more wiggle room for diner timee

Intermittent fasting is actually helpful for me and suitable for my routine ...it's helped me on my relationship with food rather than tear it down 😊I'm glad you did this video to give your point of view

For someone thats so intuitively in tuned with your body, maybe IF wont show as much impact! Especially when you know and get the energy and hunger cues. Personally, it has helped so much for my digestion and funnily enough, to help with my binge eating. Which seems to be quite common for many people

Yes please to a video on the-science-behind-IF! You’re awesome babe! Really appreciate your vibe + knowledge-based platform 🥰 xx

IF actually works great for me because I sometimes binge while rushing through hw at night. IF prevents me from binging since I can’t rly eat at night, and my lazy ass doesn’t like preparing food in the morning either. Not too big of a commitment for me personally.

First view 😂 literarily clicked so fast. Love you Natacha and thank you so much.

Hi Natacha! I've been doing IF for a year now, and I find it helpful in my case: I used to binge a lot, especially in the afternoon, and now I have decreased significantly my BED episodes. I started with a 12 hours window the first week (11 am to 21 pm), and the narrowed it down to 13 am to 21 pm. Actually, now I'm just skipping breakfast and I prefer that, because I can eat more for lunch and in the afternoon, and I feel more satisfied this way. I really love your channel and find it very informative, but maybe trying IF just for a week isn't enough - my fist week was the worse LOL. I needed a couple of weeks to get used to it. However, I know that there are things that don't work for everyone, and that's ok. It's not a critic, just my personal thought. Love you!

My family wont let me diet in peace all we cook is pasta bread and more carbs meat and shit 😭 beng Mediterranean sucks smt

I feel like your fitness channel is the only one which doesn't show your backside. It focuses on strength, function and happiness. You can tell from all the thumbnails people use on their videos. It's really uplifting to see someone who is generally so upbeat and promotes a genuinely healthly lifestyle and not just focusing on 'how to grow glutes'. :)

I never comment on videos but I feel like I should. I would not recommend IF. It caused me to have an eating disorder and it was not fun. Stay safe everybody!

your arms are goals 😍

It's interesting how different it is for different people. After starting IF I almost never think about food. And I noticed that I'm eating only when I'm *actually* hungry, not when I'm bored, sad or stressed. I also started craving healthier food which is absolutely crazy for me. But then again I always HATED breakfast and noticed that if I ate it I would eat more later in the day. But I guess it's really not for everyone

I recently found your channel and I hope raise my metabolism like you did. You really changed my view on nutrition for the good. Thanks a lot your information/help is going to stick with me for life. You can be really fit and enjoy food every day!

Can you please try the FBI fitness test?

The bottom line do whatever goes well with your lifestyle and your schedule and makes you feel well.. I love your message natacha and your personal experiments really open my mind.. Thanx alot dear ❤️❤️❤️❤️

Cool video! So I prefer to do IF by skipping breakfast and just eating lunch at around 12:30pm or 1pm and then dinner around 7:30pm to end the window at 8pm. That way I workout during my eating window around 6:30pm or 7pm because I hate working out hungry. Looking forward to your science video!

Ahh, this rang so true with me, I tried intermittent fasting last year after reading a book about it and it really does restrict your lifestyle and you are thinking so much more about food! Now I have no rules and eat in accordance to my hunger cues 🤗 Honestly cannot wait for your new guides, the hypertrophy one sounds RIGHT up my street and will be purchased immediately 💃 It's the closest thing to actually being able to train with you 🙌😩 Thanks for this vid Natacha xx

Some people only start eating at 1pm 😊 however, a lot of people I know who practice intermittent fasting don’t stick to it religiously. If they want to go out for dinner with friends every once in awhile, they go and then just start again the next day 🌸

You are my favorite fitness youtuber primarily because of your scientific background. I'm a biology major, so when you back up your information, it really boosts the quality. Keep it up!!!

My feeling window is 11:30am to 7:30pm (8 hours). Its a “weird” window but my schools lunch period is from 11:30-12.

A great giveaway idea: working out with Natacha 😍

omg this is such a coincidence because i just started intermittent fasting two days ago and you’re a huge inspiration of me but you didn’t really have any videos on it and now you posted this!! crazy stuff

Bruh she eats more calories than me and I’m 6’1 220! What am I doing wrong

I’m on my second week of IM for digestion and I’ve noticed a ton of improvements. I eat 12-8 and do find myself getting quite hungry in the mornings, but my digestion has been sooooo much better, that I am continuing to push through it. It would be awesome if you could include digestion in the follow up science video!

Hey I love your videos can you please do a video with tips in order to get abs

I never realized the help my lifestyle and diet needed until I found your channel. You are so motivating and inspiring to me to become a better, healthier version of myself. Thank you! Subscribed forever.

i would LOVE to see a science explained intermittent fasting video!!! you are one of the only fitness youtubers I trust because you’re so honest and unbiased so I know you would look at all the research💛

I love your positive attitude towards a balanced diet and fitness, staying away from negative diet culture and body image focus! You are so inspiring for a good balanced lifestyle where you can live a healthy AND enjoyable life with a focus on how you feel!!

12pm to 8pm might have been better for you so you aren't having to change breakfast and dinner times each day. Only breakfast would be "weird" by not having it.

you know the speaker is good when you find yourself nodding at what the speaker says.

It took me about 6 weeks to really start to adjust to the fasting time. It wasn't easy at first, especially in the evenings (I used to snack a LOT in the evenings), and I'd often find myself watching the clock for when I'd "get to eat", but now after about 5 months, it's much easier. It also helped learning how to make sure that I not only ate healthy meals, but also got in enough fat and protein (from various sources) for my body, but also for satiety. It made a huge difference! It's also important, when starting or considering IF, to learn the benefits outside of weight-loss (which I assume is what motivates most people). There are many ways your body benefits, from giving your body a chance to stop digesting and focus on everything else. It's pretty fascinating, actually!

Your skin is amazing! Could you do a skincare routien video?💗💗💗💗

i do everything health related like working out but i don't usually touch my food intake lololol (i mean i do the usual food in moderation and less sugary stuffs)

Wowow been waiting for this video 🌟 can I just say your videos basically function as my pre-workout as they’re so motivational and put me in the mood for a great start to the day 🙌🏽 you’re such an inspiration ♥️♥️

KETOOOOO PLEASE 🥰 LOVE YOUR VIDSSSSSS SO MUCH

I love your dedication! But as someone who’s been intermittent fasting for about 3 years (I never thought there’d come a day that I’d say that haha) you can be more flexible! I usually do 12 to 8 or even 2 to 8 but Sometimes if I go out to breakfast or go out at night I’ll just eat outside of my eating window :) loved the video though!

Seriously one of my favorite channels on YT!! Every video is fun to watch, doesn't matter what it is.

I personally love IF, I did run into the same problem with eating socially. I just moved my eating window back from 12-8 so I start with lunch and that usually leaves enough time for dinner plans

My experience with IF (last yr for 3 months) was almost exactly the same! I felt like I was thinking about food 10x more than when I wasn't on IF! Its stressful trying to plan your workday, meetings, when to train, and evening social plans. And I agree, deadlines get me focused way more than fasting :P if you do do a science based video on IF, I'd be interested in your thoughts on prolonged (~72 hr) fasts :) PS. CAN'T WAIT FOR YOUR NEXT TRAINING GUIDES!
