I started IF in mid March at 235. I’m 70yo male, I do the 16/8 fasting with my two meals being lunch and dinner. For exercise I do a 2 mile walk a day plus work at what ever around the farm. I stay away from sugar now and processed foods and now 8 months later weigh 173. Plus I’m not hungry and don’t feel deprived. 😅
Congratulations! That's been my experience too. Not being hungry is the difference between learning to fast and other diets of just cutting back. Amazing 👍
Good for you, that's wonderful 👏
52lbs wow
I’m actually proud of you! We aren’t too old to change!!
Does that mean you are not buying the 300$/yr subscription for what this video is selling?
Good job!
Hi Dr Fung. Thank you for all the information shared. I was weighing more than 526pounds when I started doing intermittent fasting and came down to 486 pounds. On the 8 of August.
I went on a full fasting, today is day 105 of fasting and I am down to 343 pounds. I was never as healthy and is still going strong. My blood pressure medicine doses was halved 3 weeks ago.
All my liver, kidney function and other bloodworks are100%. It projects that I will reach 220 pounds in the next 130 odd days. I will break my fast as described in one of your other videos.
What type of fast have you been doing for 105 days? Full fast nothing but water?
@@Iam1uglyguy Only water. I do take a daily multi vitamin. Magnesium, Calcium, B12.
Congratulations. What a wonderful accomplishment. Keep up the good work.
That is brilliant you are clearly fat adapted. I was 4 days into a week long fast.
My so called friend invited me over and produced scones jam and cream also mega cakes.
I ate only 2 scones with jam but it derailed my efforts.
I would really need to ban people from coming near me for months sometimes I think people do it deliberately .
@@yourlifecoza Sodium, too, I hope.
I don't think this message will ever get directly to you Dr. Fung, but if it should I would just like to say "Thank you!"
I've been intermittent fasting since 28. December 2021 now and have made it from the brink of obesity to the lowest weight I have been since before my memory. I am well in the "normal weight" range now and will soon start changing my fasting window a bit (for maintenance).
I would never have made it through the last year and through the falling off the wagon (several times) without your videos/ podcasts. So "Thank you so very much!" 💚 Lots of love from Ireland ☘️
I lost 26 kg since listening to you. Thanks
Great job!
I also have lost 20 kgs in 10 months n HBA1C reduced from 7.2 to 5.2 n I am off all diabetic, blood pressure meds. Thank you Dr. Fung, for me you are my saviour. I did it through low carb n IF 16/8.
Dr. Jason Fung. I am from the Philippines. I have already lost more than 30 lbs by watching ur vids and maintaining my one meal a day(ofc with the correct food u taught us to eat) fasting diet. Pls keep us posted! You’re the best.
There are cheaper devices that work too. Look for breathalyzer devices for testing how much alcohol you have in your body
I'd buy it, if it was for sale. But I refuse to rent it. Get rid of the subscription service.
I agree. It can be pricey.
This device is $400 per year (it requires a subscription), is not as simple as just breathing in and out (you have to enter all your food and exercise), has very poor user reviews, and people report that the customer service is almost non-existent. I'll stick with just fasting.
Since it is an "app" who knows what they are doing with your data.
The data you have to enter isn’t accurate, figures on food packets can be wildly inaccurate so that’s the app recommendations sunk right there. Exercise load is wildly inaccurate so again, the app relies on bullshit to give you, quite remarkably, accurate data! Yeh right.
The measurement of CO2 is probably accurate, I’ve no reason to think otherwise but the diet add-on is a waste of time and effort and is inherently flawed.
After the first year, the device should be free allowing measurements to be taken if you do not want the bullshit diet advice.
Acetone is a much better indicator. The AceTrack device is a one-off payment and has no diet bullshit.
Dr Fung here talks about the device and NOT the diet recommendations so technically he’s right and of course he has his reputation to protect but it’s a bit underhand; he should clearly state he is endorsing the device only and not the dietary recommendations.
Afford it go for it, the doctor phone gets paid for promoting this device so it's all good I doubt if anyone who could afford it actually needs to lose weight.
Good feedback. Thanks
@@susanstewart1402
I'm sure many will pay big bucks to get data on how you breathe in and out 😅😅😅
Thank you Mr Fung I have started IF coupled with zero carb diet over 7 weeks after listening to your video which by the way recommended to me by my own GP after tried multiple tablets to control my T2DM and obesity. I have lost 15 and half kilo in my weight also lost 4 inch on abdominal circumference. I can't thank you enough.
Thank you Dr Fung for this information’ Also l was diagnosed with Type 2 Diabetes’15 weeks ago. I found you then and in three months my blood work went down 8pts! I am now in or diabetes stage. My goal is to go under that and l will because of you.💜💙Thank you so much!
Thanks!
Dr. Fung, you've really helped me and many others. Really appreciate your work.
I can't imagine paying 250 for a device and then $25/month for an app that displays the device's results.
There is no charge for the device. You pay for 6 months or one year. I just paid $238 (with the $50 discount from this video) for one year.
@@bb57nychow do you get it?
I have been a follower of Dr. Fung for over two years. While I am not perfect at it I have lost 85 pounds and my A1C has went from 14 to 5.9. I was excited to hear of something that would give you real time validation. I looked into the Lumen but it seems to be more of a service than I would like with automatic recurring payments. It may work but that is just too much for me.
Thank you so much Dr. Fung. I've been followed you since 2016. I heard for the first time about intermittent fasting from You. I'm from Jordan. I used to do only the dry fasting.
Great big thanks, Dr Fung!
I agree with every superlative ever said about you, and I owe you & your gang thanks for my own weight loss journey. I wholeheartedly support your mission & message!
However, I noticed that the biggest hurdle for me was/is not the actual hunger when fasting. It´s life long habits & emotional hang-ups to food. For me, food in general, and sugar especially, is my comfort blanket and drug of choice. I eat for comfort, for a pick-up, to celebrate, to mourn, etc. Also (and this took me about 45 years to figure out), I am actually afraid of hunger! And I am probably not alone in this.
This is scientifically fluffy territory, but I think there would be a public interest if you adressed the emotional impact of fasting.
Thanks again for doing thoroughly important work!!!
Yes, it is difficult when you have learnt those eating habits and they persist around you. I receive a lot of weird looks at family gaters if I don't eat the comfort food and honestly, I feel part of the group if I just eat those foods.
Yes please address the habit side of fasting
Thank you for this. Thank you for all your work. ❤
Started TRF and LCHF Oct 1, 2022, today it’s Nov 23, 2022, already lost 18 lbs, no exercise. Thanks Dr. Jason Fung❤
What's TRF I'm new to fasting?
@@starsanmoonsish Time Restricted Feeding
I read the Obesity Code and Ive been watching your videoes.
I've been struggling with weight loss for most of my life, 10 years ago I lost 90lbs and then over the next few years it returned.
So this time I'm trying the Fasting regimen.
I'm 5 weeks in on the 18/6 Regimen, eating a light "low to zero carb" lunch and a portion controlled evening meal.
I'm walking 5 miles a day.
I've lost 21lbs, in the 5 weeks and I feel amazing. I have another 60lbs to go to reach my ideal weight, and I feel like this time that goal is attainable.
Thanks Again
36-96 h fasts won't slow metabolism 16:8 is mainly for maintenance
I am now 12 weeks in and I'm down 50lbs!
Personally, for me, i needed to stop dieting and make a lifestyle change that was permanent. Also learning to be nicer and gentler with myself help me not crave foods for emotional comfort.
@@lesw3803 lifestyle is how I've approached it now, 6 months in and I'm down 75lbs.
Im no longer concerned about weight loss, now I'm just continuing the lifestyle and seeing how where I end up
I always love your analogies like shooting a basketball to monitor your metabolism. I ways hit thumbs before completely watching. Thanks 🙏💪
Thanks!
Thank you dear dr. Fung 🙏 you're the BEST! ❤
I tried Lumen and I found it has a big problem with fasting: it can't tell the difference between ketones and carbs. As soon as you get into ketosis, it thinks you're burning carbs again which you're not. I don't think it's very useful for fasting for this reason. I returned it.
3:30 "Strong correlation" is considered when r>0.75. You can see r=0.264 in the graph, a very weak correlation. You can also easily guess it is weak just by looking at the dots distribution. Of course you know this.
I don't think it is a good idea to lose your credibility in commercial videos like this one.
I think the Lumen device is innovative and useful.
Exactly! It was unfortunate to hear the doctor makes this mistake but hopefully he corrects it because this is definitely not a strong correlation!
@@drjasonfung It might be innovative but the stats you are presenting here do not really show its usefulness… Sad😢
Thanks doc, R=0.26 suggests weight is lost without expensive gadgets for 74%
@@OxlTlxO In fact the coefficient of determination is r^2=0.07, so a not so impressive 7% of the weight loss is predicted by that gadget.
You have really helped me in this journey
This video was great but like most of us, we can't afford it right now in today's economy 😏 So I guess the real answer is....avoid carbs🤷♀️
I wish it was more within my budget. I'd use it for sure. I've recently started intermittent fasting after first listening to and then reading The Obesity Code. So far, I have lost a bit of weight and even have given up soda and energy drinks which was something I never thought I'd be able to do. Thank you so much for your videos and books.
IF is amazing and I went from 240 to 200 within a few months but I'm also 52 and post menopause. Actually giving up sugary drinks and energy drinks was a big thing for me too so GOOD FOR YOU! I'm also a coffee drinker and just recently started drinking it straight black. I know you didn't ask for any advice but I'd like to give you a little anyway. Try not to get overwhelmed with all the UA-camrs and IF. Remember we are all different so you success will look a little different. And very last, don't give up, listen to your body. I pray you find that you will start feeling amazing very soon, as most people do. God bless you 🙏
I agree, it can be pricey. I just present it as an option for those who can afford it.
Throw in some wim hoff method and cold showers. Mental clarity and cravings are cut even more. Nice work.
I love me some " bad " stuff but don't crave it like before. Low carb high saturated fat calms me down.
@@drjasonfung it sounds like it’s for keto
Congratulations! I believe I have all of Dr Fung's books. Where you liked OC you'll really like Complete Guide to Fasting. I think it was either 75 lbs I lost in 6 months on a 48hr fast, I had supper MWF I was actually never hungry. Again, congratulations!
Hello Dr .Jason Fung , Gob bless you for the life you’re saving, I started to follow in September and I’m in low carb doing Fasting and OMAD ,it works, I lost 8 kg and my glucose is between 4 & 4.9 mmol in the morning . The question I have is ,after my lunch I feel dizzy from 5.3 mmol ,can you explain me what going on please. Thank you and God bless you
I wish more of these things were affordable. I would love a continous glucous monitor also. But not sick enough to get it through my insurance and can't afford it out right. But great advice either way. I am down 20 lbs just with all your free info and books that I could get from the library. :)
You could instead just use a classic blood glucose meter and measure before and after meals. Not as precise but way cheaper and often enough to maintain weight loss.
@@GBOAC Oh thankyou! I do use a cheap one from walmart. I have for years. And you are correct, it works, I'm just tired of the finger pricking. Also, I don't want to use it forever, I just want to use it for a couple of months and see how my bs are improving, then go back to the finger prick as needed. I have had bs issues for over 20 years, so I know the symptoms.
Used this and no matter how low carb and If I did (20 hrs per day), it showed me always in carb burn. Threw it away!
Hi Dr. Fung ! I love your videos and I have already purchased two of your books. Can you please explain the difference between Fasting and Protein Diet which lead to weight loss ?
Thanks a lot for this
Thank you for your work. Read a book from you. Your explainations makes totally sense and explains a lot, that I experience.
Lost 10gk weight this year with motivation. Afterwards I started to sligthly gaining the weight back. Read your book, and understood everything now whats going on. Back on track now. Ty
The problem with calories in calories out nonsense is that while you can theoretically always control the calories in you do NOT control the calories out, your body ALWAYS does. If you diet for one week, your metabolism goes down, and it's worse with every week. You have to cut several calories of food to burn one calorie of fat and this always holds true. When you fast, the opposite happens and your metabolism goes up for the first 96 hours due to the release of adrenaline, so you actually burn more fat than the calories of cut food would suggest. Doing 72-96 hour fasts I lost over 100 pounds of fat while gaining muscle at the same time and kept it off. The absolute clowns who talk about calories in calories out such as Greg Doucette and Layne Norton have never done that either for themselves or for one single client or we would hear about it constantly from them. Without PEDs, if you are morbidly obese and follow the advice of these broscientists with degrees in nonsense non science topics, you will just lose muscle. On the other hand guys like Dr. Jason Fung have taken hundreds of patients and gotten them to lose over 100 lbs and keep it off, without surgery or weight loss prescription medicine.
Wow, I wonder how people starve to death then. Yes, a PhD in nutritional science is a "Non-science" topic. Like I said, explain how the drug wegovy works so well by increasing insulin but at the same time decreasing appetite so people eat less. How come their bodies don't slow their calories out to the point where the immediately stop losing weight? I know it is hard to understand, but when you weight less, you are carrying around less mass and have less mass to sustain so you aren't going to need as many calories. You will eventually have to reduce your calories more to lose more weight as your bodyweight goes down. Ever see the show my 600lb life? Does he talk more about them changing their hormones, or does he focus on dramatically reducing their calorie intake? Plus the funniest part is, what do you think fasting is? It is the most extreme form of calorie restriction you can do.
Nutrition is a political degree and there is zero scientific method or mathematics taught, so how are you a scientist if you get one? You're not, to any real scientist. You don't know scientific method, and you don't even have the math to talk about scientific studies. People don't starve to death from lack of calories. You can live on 500-800 calories for your whole life because your body will slow metabolism. You die of malnutrition from lack of vitamins and get conditions like pellagra and beriberi. Especially eating nutritionless foods like white rice which nutritionists love to promote for some reason.
@@LTPottenger If you think that nutritional science is just politics and made up and isn't real at all. Plus that calories apparently are some kind of conspiracy too and you could still be puggy and not lose weight on a true 500-800 calories a day and wouldn't end up looking like Eugenia Cooney at best assuming you could stay alive, I really don't know what to say to that. I can say I would think even Dr. Fung would say that is taking it way too far.
This is one I can just leave like it is and let others reading to decide if they truly believe that.
I agree that IF is a great tool and after doing keto + IF for 2 yrs and losing 60lb i really doubt that you were able to build muscle during the fasting, maybe during the feeding period but there is no way to build muscle without eating, personally i lost 23 pounds of muscle during those years. Everything in excess can be harmful even good things and it will be different from person to person, for example I developed Hashimoto during those years but my wife’s thyroid is ok and she followed the same diet.
Actually eating more calories in a keto diet + 16/8 IF and weightlifting have helped me to gain 36lb of muscle and now i have 159lb of lean body mass for my height 5’7 thats a lot and during that time have also lost 9% body fat while keeping exactly the same weight for 28 months.
@@mariol8831 dr.jason has already made a video where he explains that the growth hormone is mostly high during the fast period, and that the best way to gain muscle is to train 30 minutes before breaking your fast, and this meal after work out must have good proteins, since it's not the food you eat that make your muscles grow, it is the stress you put on them
I had looked at this before l found you Dr Fung. I will order this because l know it must work if you recommend this! So great .
Hope you like it!
Hi Dr. F, I thank God for you, i started IF coz of you ❤ … i would like to know if my sister who is a two time Kidney transplant patient is doing IF .. is it ok for her to do so ? Or will it hurt her new kidney ? Thank you very much for your reply … More power to you Dr. F ❤
Dr. Fung you are the best. You helped me lose 60 pounds and my blood pressure is back to normal, my eye floaters are gone and athrisits on my right thumb and right shoulder. Thank you, Dr. Fung. YOU ROCK! Bless your heart!
I lost around the same amount of weight too. And now that you mention the eye floaters, mine are gone as well. This just dawned on me. 😂
@@lorygarcia7980 isn’t he awesome! My sister is type 2 diabetes retired nurse from San Francisco and I told her get into intermittent fasting . I’m been doing it for close to two years. I’m on plant based diet. I look sexy now. Lol! I got my old weight back. I don’t even miss food that much. My body react to processed foods. Good luck to you woman! We need to help each other out in this crazy world. ❤️❤️❤️
I am wondering how accurate this device is? Also, does sleep apnea, asthma or copd affect results? Thanks for your explanation!! ❤
Thanks Dr. Fung for all your great material. I just have a question that is if you have any recommendations for coping with bad breath caused by long fasting periods. I have tried multiple breath mints or strips but they usually have sugar or sweetener! What do you recommend? Thanks again.
Thank you Dr Jason Fung 🙏 for saving my life. A friend gave me The Diabetes Code for the best ever gift.. Dx with a1c 11 five years ago with related T2 complications... stage 2 CKD.. retinopathy with 60 percent vision which were all reversed since after following keto diet with no medication...I lost about 30kgs.

I already have the lumen Jason. I think it is amazing! It is so handy when you are Intermittent fasting! Perfect. I have my own weight loss channel where I have lost 11 stones (154lbs) by shear hard work...I got sick and tired of struggling and constantly thinking about food! So since watching you and reading Fast Feast Repeat by Gin Stephens ( who mentions you in her book) I am now following an Intermittent Fasting lifestyle and LOVE IT. So thank you so much! ❤️ I truly feel I can actually live life instead of thinking about food and diets!! I am FREEEEE!
What did you learn from lumen?
Where can I purchase lunem please
@Baxter Using the lumen it showed me when my bodybwas burning fat or carbs for energy. Sometimes ai thought Inwas burning fat but when I blew into my Lumen my body was still burning Carbs for energy so I could tell by what I had eaten that that food took longer to digest. Also when I Was STRESSED, it too showed that I was burning carbs. Its a handy little thing to have. The link is in the description.
@@emmabright1602 if you read Jason's Discription there is a link where you can purchase.
I looked into the lumen. Unfortunately, for me at least, it's too expensive--especially because there's a monthly fee after you've bought your equipment and used it for 6 to 12 months.
Thank you doctor for your great podcasts !! May I know your opinion about using ozampic for weight loss? Thanks
Sounds like a great device . Novel prize to the person who conjures up a simple device like that for measuring fasting insulin ✌️
I get that it is a biofeedback device but can you explain how we would adapt our fasting/eating in response to this feedback to get better/faster results ?
Ty Dr Fung but I’m very disappointed that there is a subscription service. This is ridiculous. And I think will hurt their entry
I agree, but I have no input on that.
@@drjasonfung you are great. Read both your books and have gifted them as well. Be well
Thanks so much for these very informative and eye opening videos. If an overweight person has lots of fat on the body and carb stores, you are not going to burn the fat right away until you burn the carbs offf frst?
Love my Lumen! Down 7lbs in two weeks. Great bio feedback tool. Thank you 🙏🏽 for recommending it.
Dear Dr.Jason, many thanks for sharing this information.
Can H.Pylori cause insulin resistance?
Is it advisable for a person with H.pylori to fast? And take AVC??
While Lumen seems to be a great advance in medical technology, unfortunately the company behind the product seems to have implemented the greedy & unacceptable business tactic of a forced subscription model, instead of allowing a one time purchase as we used to have since the beginning of time.
Hi Dr Fung. I got a Lumen on your recommendation . I think it’s a reasonable price for a medical device. My insurance covers Freestyle Libre glucose monitor so I don’t mind the cost of Lumen although it would help more people if it costs less. I haven’t honestly been disciplined enough but I will keep trying. Of course the diabetes meds made me gain so much weight. Since cancer eats glucose and glutamine I need to do intermittent fasting, less calories, cleaner keto. With immunotherapy my tumor is now the size of a raisin
The less carbs you eat, the less desire for carbs will be present. Wishing you the very best. Replace the words “need to” with “want to” and then to “I am”….. big hugs! You can do this
That's what I need.
Hi Dr Fung. Please make a video on what u eat in a day
With all of the gadgets out there on the market - what is better to have - a continuous glucose meter or the lumen?
Thank you Dr. Fung for your knowledge, time and commitment to helping others!! I just ordered the Lumen and cannot wait to get some bio feedback!!! ❤
Pls Order for me i can't afford it Nigeria is hard
@@ijeomauzozieopurum4000 lol a lot of us Americans can't afford it. Don't go begging to random people on the internet.
I am on a 7 day fast and blood glucose is 50 and ketones are 8. I feel good. What are your thoughts as to why? I have been reading your books and on a ketogenic diet for years.
I ordered the device but forgot to use the code; however I took advantage of the cyber week sale so I dud get a discount. I will not be using it for weightloss but for maintaining my metabolic health as I continue keeping my tyoe 2 reversed and my blood pressure normalized. By the way I'm now a LMHR and looking forward to Dave Feldman's, and partners study on LMHRs
Would this be a way to confirm you are in “Zone 2” during cardio? Normally you would need to measure your lactate levels through a blood drop test.
was also thinking of that, would we be able to see if we are in zone 2, there is a lot of endorsment for this product, but on the same time very little encouragment from real people who are using it
Lumen since the inception has never upgraded the device. Some say the breathing is difficult with Lumen and requires multiple attempts to get a reading. I wonder if 2.0 will be easier to use, more accurate and possibly measure additional data points such as ketone, etc.
I was interested in the device until I went to their store and realized they want an expensive subscription to keep using it. You can't just buy it. You gotta keep giving them lots of money every single month. Too bad a less scummy company didn't invent this device -- hopefully another one will.
MUCH THX.
How does this contrast with the various ketone monitor techniques?
Thanks Dr. For your all the videos..Dr. can you please do video on dialysis. Is there a hope for kidney to come back after being on dialysis.
The Lumen device would be awesome, if it was not a subscription model. I categorically refuse to support subscription models that are not offering any additional benefit beyond what could be realized without the subscription (I.E I stream Netflix and continue to get new movies. But with this, I simply keep paying for the right to use it. No thanks.)
I hear you. It can be pricey.
@@drjasonfung - A bit, but the bigger issue is being charged money for absolutely no benefit. It's common now, and more and more things are going to this model. It'll fail eventually when people are being hammered for literally every single thing they already own, but for now, our only option is to refuse this model. Anyway, love you book, your content, and your channel!
I read a bit about the Lumen. Not sure it would be that useful for the price. After awhile I think it would be just another thing in my drawer.
After watching the Lumen video by Dr. Fung I proceeded to place an order for a unit. Only until after I completed the process and ordered a unit did a disclosure appear this is not for diabetics. I had to immediately cancel my order. This was a waste of my time. I watch Dr. Fung's videos often respect his information. I am very disappointed he did not make the disclosure in the video. It's hard for me to believe he was unaware.
I ordered one because I want to have a better idea of when I switch to fat burning and I have impaired mitochondria so don’t seem to process carbs well. I want to see the data.
This is very fascinating! My own question is how is this much different from ketone sticks? My understanding is that the darker the ketone sticks the more fat you are burning so isn’t this very similar except that you’re breathing rather than peeing on a stick? In simpler words, does the lumen device give you any more information than you would get from a simple ketone stick about how much fat you’re burning?
hello doctor! how are you? well, I've been wondering for a while and never understood: why do some people eat a lot of carbs, especially sugar, and do not gain weight? people from my husband family eat a lot of foods rich in sugar, but they don't get fat. Why this happen? Thanks! I love listening to you and learn about health
We are all different, so we have to find what works for us.
May not be getting fat on the outside, but I bet they’re fat around the organs
@@Peckerwood420 yes, I bet it too. I just wanted to understand why that happens, sice sugar stimulates insulin. But I guess It has something to do with the insulin sensitivity, right? I gained 30kg in my pregnancy, and now I've started doing IF and cutted sugar, white flour etc. But my husband ate as much sugar as I did and simply did not get fat. Just as his mother. That blows my mind 😅
@@lorelayne14 sounds like the have crazy good metabolism to me 😁
@@maryfolks9368 I wish I had it too 😅😅😅
Interesting video! Having lost 158lbs. by reading your books and watching your videos, I've learned how to eat to burn body fat. Most importantly, I gave up ALL refined carbs and sugars. They just make you crave more refined carbs and sugars...and they are addicting. And I learned how to fast. I love how I feel now. I'm 59 and the results have been amazing.
I can certainly see how this tool could be helpful. I'm starting a community outreach program/support group, to share my story and hopefully help others to learn how to fast. We will be reading The Obesity Code and discussing, watching videos and lectures etc. I'll check this out, learn more about it and share with the group that it's available. Thank you for all you do 😊🙏!
Great job!
@@drjasonfung Thank you so much Dr.Fung. Any thoughts or suggestions for our community group? We have quite an interest already and will begin in January. I will also inform everyone about The Fasting Method. It's my first time organizing something like this 😃👍💪.
@@drjasonfung Please watch my story on The Magic of Fasting UA-cam channel! 😃. Just one of the many thousands of lives you have changed. 🙏. Thanks for all you do
Can keto test strips or a ketone breath analyzer be utilized for those who are unable to afford lumen? Are they just as effective because they also provide immediate feedback to the user? Your videos are incredibly informative and helpful. Thank you for providing zero cost information to consumers👍
Exactly my thoughts. I have a Ketone meter. All I need to know if I am burning fat. Fung was paid well for this collaboration no doubt. Far too expensive gadget.
Ketones don’t come into the equation until you are running fully on fat plus gluconeogenesis aka ketosis. and thus you need to bring carb intake low enough to bring out the ketones. while with respiratory quotient it also works in non ketogenic scenarios.
@@sudsgroup I have a ketone meter too which is definitely helpful!
There is a link in the description if you want to know cost. If you are measuring ketones this device is probably moot.
@@seanlevoy9446 - Exactly. A ketone meter regularly used makes this device entirely unneccessary.
Hi Dr Chung when I fast my Luman reading is high, I’m doing 19 /5 as I find this quite easy I also eat a low carb diet . I would be grateful if you would let me know what is happening. Thank yoi
Does buying the lumen require an additional subscription monthly fee to be able to use it?
Can u just buy the device without having to sign up for a monthly pkan, etc?
I am a diabetic for 2 years now. My sugar was 600 Saturday inspite of taking metformin and regular insulin. My triglycerides were 600 and some change. So
I ate only beef butter bacon and eggs the last two days. My sugar is 151 with no medicine tonight. Im not hungry on this new diet i found on the internet. I think i can skip meals easily
Also Dr. Can you please do video on Purina. Is there a medication to stop protein loss in kidney. Does intermittent fasting solve the kidney issue.
Could I suggest a small note on this video? PLEASE highlight that these devices are NOT recommended for Type II diabetics. I have learned so much from your videos over the last 5 yrs and because it has worked well for me, I don't question information from you. THIS would be the exception... I did order it and after going through the process to enrol, that was when it became obvious, it was NOT a good fit for me. Followed by several weeks of dealing with the return process (across the border) and now still waiting for the refund.
Dr Fung, hi! How does this correlate to measuring ketones? I have a weird situation. I am successfully in a 20/4 IF . I am solidly in ketosis. Daily carb load is easily under 25g. I measure ketones and they alternate between .8 and ~2.5 daily. My weight lose have been pathetic at ~ 1.5 lbs/wk. My glucose alters too from mid 80s to 113ish. I'm stymied! I should also add I do 45min of elliptical/ day.
?? Perhaps you are eating too much dietary fat so your body is not getting to burn it’s own fat.
By eating low carb. and having a short eating window, does it make it tougher in the future if carbs. are eaten? I'll listen to this video tomorrow in the car, but that's the question at the moment.
AWSOME CONTENT AWSOME 👌thanks but kinda hard to understand but yes AWSOME CONTENT 😀👍
That chart didn’t look like it was demonstrating a particularly strong correlation between RQ and delta weight. I understand that software can provide a curve or trend line for any data set, but that looked questionable. Also, how do we differentiate between cause and effect?
Looks interesting and I appreciate the info, but I'm not a big fan of subscriptions.
I could certainly see this device being helpful for those trying to verify their keto diet. Folks doing a daily time restricted diet could use this to fine tune their eating periods.
But for someone who is fasting, I'm not sure what extra or useful information this could provide.
I found the subscription plan totally confusing. It's a device so why is an app needed? Can't it just have an LED readout that tells you the Respiratory Quotient?
dr. Jason, the lumen device is very expensive, cant we use the Aceton breath devices instead
Hi Dr. Fung, I am your fans and I enjoy frequent prolonged fasting. Recently, I started to wonder that if I have hypothyroidism, can I still do prolonged fasting? Thank you!
Hi Dr what type of exercise can I do with fasting
Does a Lumen show the same thing as keto strips or a blood keto / glucose meter?
I'll save y'all a click if you like me prefer to buy versus rent things: Lumen is a subscription based service. There is no way to just get the device and use it. (or maybe there is if you can hack it?). Very disappointed that Dr. Fung for not making that clear...... Hopefully this gets knocked off soon so we can just buy the tech....
Dr. Fung - How does this compare with Keytone breath meter please ?
73 yr old female..24 hr.Omad just maintains my weight.I am still pre-diabetic so have cut all high carb,all sugar.(I had a thyroidectomy in 2010) I walk every day but still have osteoporosis..I will not take drugs for it.I am adding weight resistance but hear I should be on an alkaline rather than keto regimen???
Expensive device and needs also subscription.
What about measuring blood ketones?
thanks
I have a lumen and I hate it. They don’t give you enough information. It’s vague. I’m so glad someone in their FB group told me about your book. I read your book and started doing alternative day fasting and it’s been so much better than the Lumen app ever was. I do still breath into it just to see what’s going on with it but their recommendations are not great.
Hello, How long should I fast using Lumen. Just purchased. I woke with 5 score and had fasted for 14 hours prior. I'm looking to lose weight. As the morning progressed the reading went down but I am not sure how long to fast for before eating again? Should I eat as soon as the rating goes down to 1-2 fat burning rate and how long should I remain with that rating before a meal? Confused
New subscriber
Thank you Dr. Fung because of you I’m a lot healthier. I lost sixty pounds doing intermittent fasting.
That's great, congrats. What do you eat when you eat? I have been doing OMAD for a few years with zero success.
@@EEEBA1 I do 18-6 hours I eat at 5:00 p.m and my next next meal will next day at 11 A.M. I eat small portion of protein (white fish) sometimes (two boiled eggs) and i purée my vegetables. My purée vegetables is my filler. I boil two cups of any vegetables and I purée and drink it. Two cups of coffee no sugar. You can eat anything that is not processed and no carbs. Eat anything in moderation as long as it’s not processed. I drink water in between . When I’m really hungry I just chew on handful of walnuts. My diet is kinda boring but it worked for me. I quit the bread, pasta, rice, sugar and pop. My sister is diabetic 2 she lost ten pounds already in one week. She started last week Nov. 17, 2022. She was on metformin for eight years and quit cold turkey last week. With metformin, her glucose always around 240ish. Now, that she lost ten pounds , her glucose reading is 160ish. Unbelievable, a humble simple intermittent fasting is healing her diabetes 2. She was also injecting insulin and she quit that , too! Try it! You can do it! Just put healthy food and drink when you break your fast.
@@GraceDollesin Thank you for responding. I will try that strategy. And I'm happy for your sister, that's great news.
@@EEEBA1 ❤️❤️❤️
is this analogous to measuring ketones as a guideline for whether or not we are burning fat?
Dr. Fung,
The current lumen community has been confused and frustrated by the high tested number after a long fast, my number goes up from 2 at fast 12hrs to 4 at 16 -18hrs … Lumen community generally has the response about long fast caused body under stress, losing muscle for energy.
There must be a reason why the number goes up and based on this video it sounds like it’s probably using other stored protein like loose skin… which also raise co2?
Could you pls do a video to explain how lumen respond to long fast ? And why the number goes up ?
Some ppl shows their number goes back down to low number and fluctuate in a 48 hours fast.
Thank you 🙏
Where I can buy this lumen device eagerly waiting for your reply love you from kashmir
Hi Dr Fung, Im on the 4th day of a 10day fast and I'm feeling acid/burn in my stomac, is there anything I can take (water, supplement,etc) that will lower the burning sensation without breaking the fast? Thanks
If anyone is in the same situation, in my case I have found that sleeping with my head elevated and drinking water with a wee bit of baking soda appears to help moderately.
I would like to hear about stearic acid. There is a study I heard with people taking banana shakes and stearic acid. The stearic acid group had increased mitochondria activity and preference towards fat burning.
Was it produced by the Banana Marketing Board? Bananas are laden with sugar, I respectfully suggest you would be healthier to gain your stearic acid from fatty beef and pork, however if you really seek to twist the dietary advice it's also added to many types of chocolate for mouth-feel so just ignore the insulin spike while you dream of a juicy steak. 🍫
@@SpamMouse bannas were for starch, not stearic acid. The study explains it.
Stearic acid is the fat commonly found in beef.
@@DaniGirl6 Indeed, I covered that - the issue is bananas are laden with sugar.
@@susanstewart1402 cacao butter is also a source high in stearic acid.
🎯 Key Takeaways for quick navigation:
00:00 🔍 *Understanding body fuel: The body primarily uses glucose (from carbs) or fat as fuel sources, with distinct pathways for each. Burning fat is crucial for weight loss.*
02:08 📊 *Respiratory Quotient (RQ) & weight: Monitoring RQ helps determine if the body burns fat or carbs. An RQ closer to 0.7 indicates fat burning, linked to weight loss.*
04:14 🌀 *Lumen device: Lumen simplifies RQ measurement by analyzing oxygen and carbon dioxide, crucial for understanding if the body is burning fat or carbs.*
06:10 🏀 *Biofeedback & diet: Similar to immediate feedback in sports, knowing if your body burns fat or carbs helps adjust diet for optimal weight loss.*
07:21 ⏱️ *Changing RQ: Adjusting diet or intermittent fasting can shift RQ towards fat burning (0.7), aiding in utilizing body fat for energy.*
08:26 🧠 *Biohacking for weight loss: Understanding body fuel through RQ measurement is key to optimizing weight loss strategies and maintaining weight loss success.*
