Starting a three day fast from Thursday and breaking it with our Easter meal to honor Holy week 🙏. I'm actually looking for to it! Is that weird? 🤪🤣. Thanks for all you do
@@JohnsonNestorFamily Three day fasts are so good. Have fun with it. Be good to yourself.
@@AzaleaBee Thanks Azalea!🙏
@@jacobstaff549 Me too! Drives my husband nuts 🤣. Last summer I decided to paint our house!😆
@@jacobstaff549 It's because of the counter regulatory hormones. Dr. Fung talks about it in several of his videos. Interesting stuff!
I fast for 22-23 hours per day for everyday and have one large meal around 6pm-8pm. I exercise 3 times per week and have them before I break my fast. After more than 8 months of practicing this, I have gone from 104kg (230lbs) to 81kg (181lbs). It is not much weight loss in those duration but I felt the healthiest I have ever been in my life at age 28 years. I felt that I have so much energy exercising during fasting state compare to consume meals before a workout. Having this, I encourage more people to fast and exercise. Dr Fung really knows this stuff!!!
Awesome!
104 to 81 is a lot!!! Good for you.
@@anamariasoriano5880 yeah same here, from 112 ~ 117 KG to 86 ~ 90 KG , with similar routine to yours.
20kg is no joke.
That results in 3kg weight loss per month, which IMHO is a good and healthy rate. Well done & congrats!
I have lost over 75 pounds. Down from 305.
I Intermittent fast all day while working my construction job, and then eat between 5ish to 9ish. I also eat normally every weekend. Though I still almost naturally eat a lot less during the day even on non IF days.
This has been amazing for me. I LOVE intermittent fasting.
Has anyone noticed that IF totally changes your relationship with eating??
I don't even think about or desire to eat in my fasting periods. Huge for an over eater like me.
Thanks for all your advice in and info Dr. Fung
I'm on a 7 day long pure water only fast right now, I have definitely lost a lot of my desire for food.
It's just the first 1-2 days that are the hardest, but after that my body has adjusted and as Dr. Fung says, I'm in fat burning mode.
That's pretty similar to what I've done, this last year. It's easiest to fast, while working... and of great benefit.
Thank you. I was diagnosed with Type 2 diabetes 22 months ago while in the hospital four days with pancreatitis. I have been taking Basaglar and Humalog since then. First 25 units of Basaglar each morning for about a year, then increasing to 35 units, then a few weeks ago my doctor said to increase to 50 units each morning. I thought.. this is ridiculous (and expensive), there has to be a better way. Then I found Dr. Fung on TH-cam and watched probably 15-20 of his videos, including several conference presentations. He really spoke to me and I ordered The Complete Guide to Fasting and The Diabetes Code. I finished The Diabetes Code a week ago...what an amazing explanation of what's going on inside my body. I have been doing 18/6 intermittent fasting for about 3 weeks, eating around 1000 calories around noon and another 1000 calories around 6PM. I have already lost 15 pounds and 4/4/22 was my first day without any insulin in almost two years. This is the best I've felt in a long time and now am excited with hope!
NICE!!! Good for you for taking charge and finding a better way!
Congratulations and that is absolutely wonderful. Taking control of our health with accurate information is extremely important. I will tell you though that the name you chose for yourself, the screen name of deplorable created a hesitation in me to even message you. Perhaps the message it sends is not the one you intended.
Congratulations on taking charge of both your health and life! As a nurse, I've taken care of many diabetic clients. I can attest to the fact that many doctors seem to be totally clueless about what diabetes actually is. Dr. Fung also helped me change my life around over a year ago. I reversed my diabetes completely. My own GP was no help at all. She was not supportive and actually told me that I absolutely needed a good quantity of carbs to get through the day. Wrong.
@@Kyarrix Big yikes, friendo, very toxic and problematic. Hopefully my name doesn't trigger you as much
That's awesome!! Good for you for doing something so good for yourself.
When I first started exercising while fasting, I was a bit concerned on how my body was going to react. 3 years later of doing weight training and cardio while fasted has resulted in the best shape of my life. I'm 44 amd feel amazing. Tons of energy, no bloating and zero joint pain inflammation. My Tennis elbow and lower back pain have disappeared. 👍
Do you exercise near time to break the fast?
@@krawkovski Actually, I workout fasted at the end of my shift at work, which is at around 3:45pm. We have a decent wieght room gym, so I just jump at it right there. 👍
@@krawkovski I do have black coffee and a ton of water sometime before though.
🔥
I am having great results. Lost 50 lbs and running better than I have in 25 years. I eat all the time and eat pop tarts before every run.
I rarely find myself hungry since I started fasting 👍🏽 24 hours fast is now easy ! 🥗
The longer I fast, the less hungry I feel. I love the energy I get.
same
Once your body changes to keto fuel.. no more hunger and gaining greater energy..
I am on a 14 day water fast. I finished day 5 with a huge 3 hour hike in the colorado mountains 14000 ft elevation. And it was the most easiest hike ive ever done! My knees didnt hurt at all (which is a first for me). I had boundless energy. And i just felt AMAZING. And more spiritually intuned. And once we got baxk. Didnt have the urge to eat. Its amazing. Water fasting is amazing! And im not even sore! And my mosquito bites faded away quickly. Mind blown!!!
Awesome! I want your experience
I tried for 40 days but I could only do 16 days water faster but I felt amazing as well did light weight training and cardio as well lost like 90 lbs and feel and look great no sagging skin either! Fasting is just amazing!!!
Congratulations Shannon. I’m in the Boulder area, on day 5 of my 21 day fast and thought about a similar hike. I was slightly worried but am now inspired, thank you.
@@myvideoplayingdevice9114 Wow. (and congrats) How did you know to stop after 16 days? I haven't gone nearly that long yet, though I think it would be great for my cancer.
Did you take Sodium. Potassium and Magnesium to help maintain the electrolytes whilst drinking water?
I've noticed that when I fast, the more I move, the better I feel. Plus, my motivation to get up and be active is higher. Does anyone else have a similar effect, or is it different in some way?
I feel the same. when I'm fasting I feel like I can walk on water. My energy levels are high and I feel great. The second I start eating (even healthy foods) I start to feeling crap. So interesting
Yes u feel more energetic and motivated 💪
Yes I explained the same thing when I move more I feel better. I just hate the metal taste in my mouth when I do Several day fasting
Yes. I think moving around helps keep my metabolism, body temp going. The mind has more energy to think about chores that need to be done, haha!
@@tiolenealvarez1364 I googled it real quick just to see what the first results would say, so take it with a grain of salt of course and go check it for yourself, but this is what I found:
The metallic taste is excess ketones. If your body is not used to using ketones, some will be excreted in the urine and saliva. If you really goose your ketogenic metabolism, your body gets better at using ketones and the taste will go away.
Fasting changed my life. It’s my superpower!
i feel the exact same, its like a realm of disease-curing and weightlosing knowledge that you wish you could go around and share 24/7, unfortunately people are not always receptive.
@@CarlitoeGames 💯
I’ve been Doing this since January and it works.
I do a 6 mile walk 5 days a week while in a fasted state ….
I’m down 30 lbs in 3 months
I fast every month for 5 days. I only drink water. I did this all 12 months in 2023. I’m doing it again in 2024 since the benefits were so amazing. The only thing I changed for 2024 is to start the year with a 21 day fast. I’m on day 17 and feel great. Again I’ve only drank water the entire time.
Great video again! I didn't feel well enough to exercise until I lost my first 60-70lbs. Then I remember listening to one of your podcasts where you said to exercise as usual so I started back swimming last spring, about this time last year actually. I'm so glad I did! It felt sooo good and I've kept it up since and still swim laps twice a week. I actually feel my best and swim faster on my longer fasting days. I've ended up losing over 150lbs, even got my lifeguarding certification and now I'm working at my pool! What an amazing transformational experience. I'm loving my new life ❤️🙏😊. Thank you for all you do
Way to go, Jessica!!!
👍🙏😊
This is encouraging. I’m in the beginning of my weight loss goals and need to lose 120 more pounds. Sometimes I get out of breath easily when not eating so I take extra breaks to get things done. Then again, sometimes I get out of breath when I eat. I’m just out of shape lol. I’m not a swimmer but I like walks and garden work. Your testimony was helpful because I was at one point over 150 pounds overweight. Thanks
Hi Jessica! Happy Sunday to you.
I want to emphasize your second sentence.. that you didn't really exercise much to lose your first 60-70 lbs. We've learned this.. but I want to shout it off the rooftops ... and maybe slap it into some of my family members and their doctors (lol)
Exercise is good.. and recommended but for other reasons.. but exercise is not necessary for body fat loss particularly when one is obese/very overweight.
Thank you for sharing with us……….You are an inspiration. I wish all of us a healthy happy life
Hi Dr. Fung
I want to thank you the other day when I bumped into you in the hospital. You were very patient with me, and I also appreciated that while you were on your way out, you gave me some of your time to answer a few of my questions.
When I came back upstairs to my room, I showed how happy I was to finally get to meet you. You're awesome. When I come out of hospitall and recover, I'll then start my fast.
I'm 70-years old and tired of being per-diabetic and over weight. From Mr. Fung's books, my eating window is 5:00PM to 8:00PM daily for the past 90-days. While not eating, I do water, coffee, or tea only. I do a kettlebell or body weight workout (heart rate up to 95% of max several times) for 30 or so minutes daily, then walk 2 miles at a relaxed cool down pace (20-22 minutes per mile). My basal metabolic rate is about 2200 calories so I limit intake to 1700 calories daily with macros of 20% carbs (really low sugar), 50% good fats, and 30% protein. I've dropped from 235 lbs. in January to 212 lbs. today and am rarely hungry. I don't go in for blood testing until mid-July, so not sure what's going on with triglycerides, glucose, etc. Hopefully improving. Dr. Fung is a national treasure.
I've been doing IF for a few years (17/7) and recently started doing weight training near the end of my fast. I take only 1,000 mg Taurine in the AM. I then take electrolytes, 2.8 grams Beta Alanine and 600 mg DMG during my work out. Because all the lactate buffering I get, the limit during my work out is a BODY HUNGER that is UNREAL. It is a totally different "HURT" then a muscle burn that is normally felt. The only issue is that it makes you CRAVE more sets... as intuitively my body something GREAT is happening. I just started doing my leg work out fasted and I am surprised how strong I am getting. At 67, I am squatting 480 lbs. When I turn 70, I am planning on breaking the world record of 365 for a 70 year old at 198 lbs. TRY FASTED WEIGHT TRAINING!
@@user-he9kr3rf6wYES!
I am 65 and train 6 days a week fasted at around 13 hours and do not eat till 16 hours. Mondays I lift fasted for 33 hours, and is the best way to lift EVER!
You are not alone in this discovery.
I fast 15 hours everyday and lost 79lbs through diet and exercise. In the first 2years everything was great, lots of energy. But then I hit a plateau in strength training and seemed to struggle with it. Hard to increase weights or reps every other month and seemed I was straining just maintaining. So I consulted with a sports health coach exactly on the topic of before or after fast. They suggested to eat before workouts. I immediately found strength and push thru with ease. I can now increase exercise volume as scheduled, have more energy throughout day, hence burn more energy. Note, since already at my body weight target strength increase is the priority at 63 years of age. In fact, body weight is slightly increasing but I also am finally seeing muscle hypertrophy. I consider a more holistic approach to lifestyle and adjust accordingly. These videos are great sources to learn and discover different approaches that may fit your lifestyle. Thanks.
Hello, I fasted 72 hours weekly over a 75 day period in 2021. I lost 40lbs. I walked 10 km per day even while fasting. It was no harder while fasting than during fed state.
Was this part of 75Hard?
do you have loose skin?
I do OMAD and eat between 8am to 9am. I also walk 3 hours in the mornings, 5-6 times a week. My walks are between 4:30 in the morning to 7:30 and eat soon after I get home. I feel great and have no problems with food cravings or needing more energy while walking/exercising.
Good for you 👍🏾👍🏾
Why so early? I guess you also go to bed very early. If it works for you, kudos to you!!! 😀👍
Wow that's really really early!
I definitely prefer training in a fasted state because I think I get more out of it. But I also think sooner or later we will not have a choice. Food is becoming more expensive and harder to find. The world is increasingly becoming unstable. Weather patterns and a lot of places are really starting to suck. So I would rather try to do it in a controlled setting then finding out the hard way. That way when the real hard times really start, I will not suffer nor and near as much as most people will.
I can’t say I agree with this way of thinking. But also, if you stay ready, you never gotta get ready 🤷🏽♂️
I feel awesome with exercising with fasting! I find I still don't have an appetite after.
I never thought it was possible. I'm a woman who
Lost 134 pounds over 15 months doing very very low to zero carb , IF, and doing NOTHING. just joined a gym with 50 more to lose.
My heroine!!!👊🏿💪🏾
Awesome! Keep going! So proud of you!!
What an amazing story. Nicely done.
Hope you made it through the final 50!!
I work in lawn care and general labor and I try to put the days I mow on my fasting days. And since there’s a lot of walking and full body usage involved, needless to say, I have seen some impressive results.
👊🏿
Absolutely great summary , love the analogies and insights…
Thanks Dr. Fung really appreciate the hard work you put into helping out the public.
I cannot put into words how grateful I am to find you.
I always learn something from one of your videos! I'm 2 1/2 years into my keto/low carb and IF journey. Doing 24 hour fasting a couple days a week and mostly 4/20 the other days. I've lost 40 pounds and mitigated my "pre-diabetic" condition. I stopped going to my trainer because of pandemic but trying to get back to the workouts. Thx for putting me at ease about exercise while fasting. I'm just a few pounds from my goal weight and feeling fantastic! Looking forward to trying some longer term fasting but I'll admit I'm a little hesitant! Thx for doing what you do!
Thank you for all the education that you put out. You are really helping me quite a bit!
I enjoy exercising first thing in the morning Monday to Friday. I do ADF and exercising in a fasted state is awesome. It gives me so much energy.
I watched loads and loads of similar videos but this is the most straight forward one - easy to comprehend. Thank you !!🙏🏼
GREAT info, as always.... I especially appreciate your ability to use examples to illustrate your points... in this video, the example of the hybrid car.... that adds such clarity to your teaching and makes it even more effective..... THANK YOU!!!
Dr Jason, you're ow one of my go-to to hear more about health and fitness. 🙏💝🌱
This Dr is the defacto standard for fasting. Absolutely LOVE the information he gives. 9 min of common sense, mind blowing, information to stay fit, healthy, and full of energy.
thanks to Dr Jason l have managed to reverse my prediabetic condition. especially prolonged ones brake te vicious cycle. thank you for sharing your knowledge
Thank you. This was really a big question I had about exercising in a fasted state!
Thank you Dr. Fung! I've been your regular follower. Keep up the excellent work on TH-cam for wellness.
I have lost 200 lbs following Dr Fung, I do a modified fast with no exercise due to health issues, I am medication free and all blood work is perfect for first time ever in my life and I am 50. I send everyone Dr Fungs Videos
Fricking way to go, Tribe's!!!
😲 W0W !❕
Congratulations 👏🎉!!
Amazing, congratulations. Hope you can keep your weight down over the next ten-twenty years. That is the real challenge.
I'm starting my 1 year journey now at 270 pounds to 170 pounds 🙏🏽😇🤙🏾 .
Good luck. My wife and I both lost over 60 lbs. in 5 months.
@@orowizard1369 Thanks 🤙🏾
Good luck. I am down from 352 lbs to 182 lbs as of this morning. I am shooting for 145 lb...I figure I will be good at 140 to 145 lbs.
@@lorettacarroll6015 Congrats to both you and NATO.
A goal weight is good.. but a mindset of "maintaining body fat loss" even if the scale doesn't go any lower" is one of my most important goals.
You can do this! Grab Dr. Fung's book The Obesity Code. That book.... will change your life! Good luck and be well 😊🙏
Could listen to you all day man, knowledge is amazing
valuable advice. This is what I was looking for. Thank you very much, Jason.
I love all these stories. I lost almost 60 lbs doing prolonged fasts, from 24 up to 5 day fasts and I did strength training & HIIT the entire time with no issue as long as I took my electrolytes and magnesium.
Thanks Dr Jason you have changed my life. God bless you
Keep sharing the word Dr F
00:58 🏃♂️ *Exercise during fasting is feasible as your body utilizes stored energy from body fat and blood glucose for fuel.*
03:16 🕒 *Optimal time for training is towards the end of your fast, known as training in the fasted state, leveraging hormonal changes to enhance workout effectiveness.*
05:33 🏋️♂️ *Training in the fasted state activates the body, making workouts more manageable due to increased sympathetic nervous system activity and elevated growth hormone levels aiding in recovery.*
07:50 🤝 *Accountability and guidance from a coach, as seen in James's story, significantly contribute to weight loss success and maintenance, akin to athletes benefitting from coaching for performance.*

It’s always a pleasure to listen to you, dr. Fung; the videos are very informative to comprehend the concept. Thank you!
Clearly explained. Thank you Dr. Fung.
I've been following your videos recently. I'm extremely active but have continued to slowly gain weight the last two years. In october I decided to drop carbs and have been losing weight now. in november Ive found your content and now actually understand why i wasn't able to lose weight. Really appreciate the info.
Thanks! Down 20 lbs in 30 days.
Wow! Aren't you losing too fast? Just be careful.
@@dollmm23 yeah I think that’s too much
Everyone is different! That is less than a pound a day. Not a problem for most.
I've always trained fasted. Seemed much better for me. Actually, I can't train/concentrate/hike proper if I'm digesting a meal. Thank you for your life-saving videos!
Thank you for another excellent video 👍🏻
Gotta Love Dr. Fung. 🙏
Dr Fung, Thank you for your continued dedication to educating people and supporting them in their quest for better health.
I have been OMAD since Nov 2017. For much of last few years, I coached tennis 7 days a week while fasting. At one point, i was coaching 49 hours a week. Last year, I started taking Wednesdays off of coaching... to have a day of chiropractic, massage, and PNF stretching. After the therapy, I go to play badminton for a few hours. As a result, I have been able to maintain body composition (12% bodyfat) and weight within 5 lbs of my ideal weight (for playing competitive tennis).
When I lose discipline and gain weight and bodyfat, I have done extended fasts to get things back into range. 48 hour fasts are a piece of cake now because I don't get hungry at all. I have done a number of fasts of 72-98 hours. My challenge is not hunger (because i think my body is used to not producing ghrelin), but the desire to taste food (which I love) and enjoy the act of eating.
I bought and read Dr. Fung's books and have many of his videos saved in the Fasting playlist that I share with others (close to 70 videos). I started coaching 3 people on intermittent fasting who I met during the past 2 weeks. As living proof that fasting works, I am on a mission to share this information with everyone who will listen!
@tsolomonliu could u share the playlist?😊
I loveeeeeee the way this man teaches!
HUGE CRUSH ON YOU DR. FUNG!😍😋
Always helpful info. We learn so much - thank you!
Thank you Dr. Fung. You've done it again. People often ask me this question. Now I can have some scientific answers for them.
Thanks sooo much Dr. Jason Fung!!! You're the best!!! 🥰❤
Hi Jason I am so grateful to you for your guidelines! I always live active lifestyle been that way all my life! I swim daily and long walk at night I didn’t have hunger problems! People asked me how to do it I said first self discipline and commitment to yourself
Yet another person arriving in my life at the perfect time, with a message I can now fully hear. Thank you ❤
I was 240 (6ft) September, now down to 204. I do IF (off and on, fell off for 2 weeks), walk 45-60min. I consistently walk ,and do light weight training. I still eat my snickers and girl scout cookies (420)😂. My labs are great, no pre-diabetes. Because I have so much belly fat I can workout while fasting and never feel bad. Our fat is a good thing right now, it allows us to work hard without the food. I am gaining muscle and strength. It sounds corny, but it is a lifestyle change.
Exactly the information I needed today. Thank you!
Thank you again, Dr Fung.
Thank you Dr. Fung!
I love how you make it easy to understand about Blood glucose and stored energy. If you fast you’ll use body fat.
Most importantly I’m thrilled to hear that exercising while fasting is safe. Also, knowing to exercise at the end of our fast then eat makes perfect sense.
Your such an awesome Doctor! Thank you.🙏🏼
I’ve lost 35 pounds since mid November doing keto with intermittent fasting. I eat large meal a day about an hour after my workout.
This was so helpful thank you so much! 🙏
So interesting, I could listen to Dr Fung all day.
Dr Fung is so so blessed
Dr. Jason you’re the best. I have started doing OMAD and this is my 2nd week. I’ve already lost 3 pounds .I always used to feel that fasting is tough and it’s very difficult. I actually started with IF and now on OMAD. I guess I will never ever go back on my previous eating routine or pattern and reason being I feel so good, full of energy, my mood is good. Seems like I have accomplished a lot with OMAD. I exercise very well on OMAD. I guess it varies from person to person. Thank you for all your videos.just to add one more thing which is totally my experience is that with OMAD my will power has become very strong and I see myself as a self disciplined person.
Well done!
What is OMAD?
Excellent video as always Dr Fung your helping me reverse my type 2 diabetes, all the best from England.
One of the Best doctors on the planet..!!!
I started 16/8 IF a little over 2 weeks ago. Also got my doctor to rx me a GCM since I am currently non medicated type 2. In just these past two weeks following the 16/8 I am already seeing my BG levels normalizing again. Something I have had such a hard time with. I do see a spike around my workouts, but nothing major and calms down within 2 hours after my workout is over, then remains in normal range the rest of the day. All the traditional "diet/eating" plans that my medical team told me I needed to follow was big part of my issues. Eating too often and too more carbs than my body handles well, even though I was staying under their daily recommended levels, I actually cut the carbs by 1/3 and my body feels so much better. Getting used to the 16/8 and hunger pangs wasn't super hard either. I am surprised at how much energy I have after only two weeks. I am now up early in the morning, head to the gym and get a good workout then on with my day. Why don't more doctors suggest IF and lowering carbs for treating diabetes?
I was diagnosed with fatty liver and pre diabetes and maintained it many years. I started intermittent fasting 17-18 hrs a day. Starting my 4th week, had a dr appt and blood panel done. A1c is 5.6, HDL is high at 69, fatty liver test is 17, high is 31, bp 128/70 with meds. Pretty happy with the results.
Your labs should continue to get much better still if you continue intermittent fasting and reduce sugar/carbs. I have been fasting 17-18 hrs everyday for over 3 years with a 48 hr fast about once per month and I have also improved my diet (strictly limit sugar/carbs), and my labs are all great. I no longer take ANY meds and my fasting labs (lipids, glucose, metabolic panel, blood panel, etc) are all within healthy ranges. My TG/HDL ratio = 0.6 and any result less than 1 is considered to be protective against heart disease. Fasting, healthy diet, routine exercise and a few high quality supplements are all you need to stay in optimal health.
Excellent info I was always afraid to workout without eating first especially when I fast but when you explained everything regarding this my workouts have become better without eating “a lot of people have that idea they have to eat first
Great video. I have been fasting for 17-19 hours/day for a few years and always work out toward the end of my fast. This was not on purpose, its just the way my schedule is. Glad to hear it is a good way to do it, I always wondered if I was doing more harm than good, and now I know!
I hadn't eaten for a year, just coffee & water; when I started, I weighed 875 lbs , & now I am down to 170! 🙋🙏. I started eating a week ago☠️
I did a 5.5 day fast (was aiming for 7, but my stomach acids got the better of me). I am a teach swimming in the afternoons. Was able to go to work every afternoon (and do my own 1km swim) without any problems. So yes, you can do everything you would normally do, just make sure that you drink plenty of water!!!
Ur awesome love motivating me to do my 72HRS fast after the holy month of Ramadan
Thank you Dr. Fung
luv this advice and video thank you dr jason fung!👍♥️👍♥️
So glad I found your videos!! I have been so happy with the energy I have since fasting. I was a firm believer in 6 small meals a day most of my adult life. No wonder I could not stay at my ideal weight easily! I now eat 2 times a day about 5 days a week and 2 days OMAD. I am working towards 5 days OMAD and only eating 2 meals on the weekends. Slowly making the change has been key to my success. I am 55 and feel fabulous!! Thank you, Thank you, Thank you!!!
Thanks to you I am working out every morning at the end of my 16 hour fasting period for more than a year. Lost 46kg within the first 7 months! Never looked back once!
Wow! Any updates?
@@inkofgrace of course :) I kept the weight, did not gain any back. Instead of walking I am consistently running now. Did a Half Marathon last year in 2h12min and ran more than 2300KM in the last year. Injuryfree. Still intermittent fasting. Vegan. No alcohol.
Much appreciated, ThankQ..
Thanks doc you're great!
The easiest way to start fasting is to skip breakfast until you are hungry, and expand it gradually until dinner time. And than you effectively are doing OMAD. Eating sugar, starge and processed foods will make you feel really hungry. Fat will give a satisfying/full feeling. Leafy greens, bell peppers, cucumbers, tomatoes, herbs and spices is what you need, together with olive oil and avacado and or eggs, it will be a satisfying meal.
It’s impossible to skip breakfast!
@@Hat65 read the sugar and starge part carefully , again , start with skipping sugar and starge and processed foods first, so you eat an omelet with union, mushrooms and kale, backed in butter or olive oil, but no bread.
@@m.j.debruin3041 Break...Fast 😁
@@tallowturq oh in Dutch it's one word . 🤭
@@Hat65 that is what I thought. I eat hamburger bacon and eggs for breakfast at 430am that holds me till 1200pm. 5:00pm I eat a fatty meal that holds me till I wake up to start over again. but you have to start eating more fat and no carbs or sugar before you will be able to skip breakfast it will happen slowly.
Thanks for the update. So many conflicting TH-cam videos out there on this topic.
I have watched wackos charge people for fake IF information, this is a lifestyle, dont stress over it, dont listen to everyone take some info from each and make your own model this is an amazing lifestyle once you don't think about it, stop letting your mind tell you when to eat, your body will tell you when it is time...
just found the channel. people sound so positive about this lifestyle change! inspired to try!
Very good! Thank You 🙋♂️
I tried this fasting and within 2 months I went from 353lbs down to 287lbs!! I fast for 24hrs and have one meal a day..
Awesome job👍🏽
I fasted since 545am this morning and it is currently 1245pm and I only had water 💧. I feel really good 😊.
Thanks for sharing helpful info all the time
Among the many things I have learned, I now know the importance of a Coach!
When I don't exercise, I actually have more problem with hunger and lack of energy!
I admit that I don't do a great deal of high intensity exercise (bad of me, I know); I walk a few miles 3 to 5 days per week and lately added a swim of about a kilometer to my activity. To me, it feels like the gentle exercise kinda kicks my body into mobilising my fat so I get energy in my blood and don't feel hungry. I do feel empty (which is actually a nice feeling, I've learned) but not hungry. Sometimes I even feel a bit of a buzz after the exercise, which is wonderful.
I'm mid 50s, started mid August 2021, OMAD with low-ish carb diet (waver between keto and low carb). I eat a big 800-1400 calorie dinner around 5-6pm and I generally exercise somewhere around mid morning (about 15 hrs fasted. I don't eat after my exercise (nor do I need to! all my energy has just been mobilised). It's perfect for me!
I'm actually kinda dreading hitting my target weight cos then I'll have to start eating more often and eating a small meal just makes me hungry later, which is gonna be a problem. I've lost 20.5 kg since last August and still have about 5.5kg to go. I need to start getting my head around how I'm gonna transition to maintenance diet in a way that doesn't trigger food cravings.
Intense exercise causes hunger. Things like walking might actually help. And will relieve boredom, which is an issue when people are in the habit of snacking. Avoid snacking only eat at meals, and that will solve many problems.
Sugar, starge and processed foods will make you feel hungry ± 2 ours later, because than your blood sugar level is becoming low again, it's less of n issue when/now your body is fat adapted( used to burning fat for fuel).
Try eatting bigger meals or higher carb meals Instead of more often when you hit your goal.
Your body will reach a plateau automatically if you continue to fast and exercise as before. I assume the main factor for change is aging, as the metabolic rate decreases as you get older (over 50).
My job has a workout facility and I started working out 2-3 days a week during lunch while I’m fasting. So while everyone is eating I’m fasting and working out I love it 💪🏼
It’s great to feel like you have more time in your day, isn’t it?
Golden content. Thx for changing my life.
Great work doc 🙌🏼❤
Ive been starting my fast Wednesday night, working thursday and fridays loading milk trucks by hand, walking ~18-20km Thursday, friday and saturday and ending my fast Saturday night. Ive done a total of 30 days fasting this year so far and now I have no issues energy wise whilst working and maybe a little towards the tail end of my walking.
I do OMAD 5 times a week and 48hrs fast the rest of the 2 days. I exercise 2hrs daily for 6 days. I have lost 13kg in 2 months.
I would have believed it but the 2hr exercise for 6 week a day gave your lie away
@syedarsalanahmad lie? What you talking about? I have an app that tracks my workouts everyday. I get at least 10hrs a week. When I say 2hrs daily, you should know I am likely to miss some days in the weekend. So what lie? I weigh 85kg now. I was 112kg in September 2023.
are you doing cardio only or resistant training as well on 2 days that you fast for through 48 hours?
@tracynguyen92 I don't do much cardio when I am on a long fast. I do resistant training on Saturday and walk for 2hrs on Sunday morning
Thank you for another great video. Id like to hear more anout the fasting coaches.
Excellent video, very helpful. GOD bless.
A combination of Peloton + 20:4 enabled me to lose nearly all my belly fat -- going from a size 34 waist WITH an overhanging belly to a size 31 waist with no overhang. My exercise regimen is a mix of endurance, i.e. 45 to 60 min, alternating daily with 30 minute HIIT. In addition, this includes 25 pike pushups. The combination of cardio + body weight training + fasting is magical.
Thank you for sharing- this is my plan and I’m excited to hear results like yours!
Me too!! Team Cody Rigsby ❤️ 20:4 magical ❤️
Coincidentally I started a five day water fast yesterday (Sunday), and my goal is to be able to run 10 km each day. Ran 12 yesterday and about to go for an evening run now.
Very good Paul. I fasted 7 days and ran 40 miles during the fast. I have also run 55 miles during a week eating OMAD. I consume really low carb, from low glycemic vegetables, mostly fat and protein. Energy is fine. Improving my running. Keep going!!
@@alanlierz3745 What kind of body fat do you have...generally...?
