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.

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 ☘️

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.

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!!!

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.

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.

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.

🎯 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.*

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

How does this contrast with the various ketone monitor techniques?

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 😅

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?

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.

Hallo Dr I am Tinnah am from Africa Uganda and most of the food here is carbs when I watched your video about not to eat naked carbs by adding vinegar to my meals as a means of cutting weight! I am finding it hard to poo I don't know what's wrong. Thank you

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.

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?

But don't Ketostix ( to measure ketone run off in urine ) give this same feedback?

Lumen has some incredibly predatory pricing schemes for a company pretending to care about our health.

I got a good deal on my lumen. Considering how much food companies charge us for food that makes us fat...I would prefer spending my $$$ with Lumen as they do have more interest in our health versus the giant food companies.

Love my Lumen! Down 7lbs in two weeks. Great bio feedback tool. Thank you 🙏🏽 for recommending it.

Does buying the lumen require an additional subscription monthly fee to be able to use it?

So I got a Lumen. I have been (NonKeto but low carb) fat adapted since 2020 and in the second half of 2022 I did a 120/48 weekly fasting window with low carb for the 48

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

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.

Hi Dr what type of exercise can I do with fasting

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!!! ❤

My Blood Pressure is skyrocketing and my heart is palpitating from day 1 through now, day 2.5 of fast. I'm not going to doctor's when all I need is to eat, but I don't want to give up on an intended 4 day fast. What's happened?

Dr Fung , not sure if you will see this . Can a hypothyroid fast? Some have the opinion that it slows down metabolism for this group . Please advise

I have such a hard time getting down on my weight. I did IF 20:4 every day. No carb no sugar and no fat eating. One meal a day. I have struggled with my weight the same number for almost 3 weeks. I did everything I can but the number not moving down at all. I get plateau for a long week. I don't know what I can do for this point please help any trick or technical will appreciate.

MUCH THX.

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.

is this analogous to measuring ketones as a guideline for whether or not we are burning fat?

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???

I love gadgets, but don't really see the advantage of this method of determining fat burning vs my ketone meter. If it's the non-invasive aspect of it, I think that's offset by the need to tie it to an app. that is tied to a mobile OS and tied to a particular device. I have no control over any particular app's support or its continued suitability for any particular device, OS update, etc.. All I have to worry about with my ketone meter is making sure I replace the batteries when needed. I reversed T2D through the use of my ketone meter.

Lumen sounds like a fairly accurate way to measure an imprecise metric, the RQ study you shared showed the relationship between RQ and fat metabolism only had an r < 3.

does this mean that Keto will decrease the amount of CO2 produced - will that affect my asthma?

Will it be accurate if I have asthma and don't always breath that well?

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.

Dr. Fung - How does this compare with Keytone breath meter please ?

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.)

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?

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.

Lumen says right on their website, people with diabetes should not use their product. Do i or dont i try it? I am recently diagnosed with type 2 and not on medication.

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.

Is there peer-reviewed data with this actual device and sustained weight loss? It would appear to be a great tool, but in the real world, with real people and real diets, does this actually make a difference? The device requires a regular subscription fee and I wish you would have spoken to what is expected of consumers when purchasing this product.

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.

Oh goodness I did the same thing until I went on full carnivore. Unbelievable changes I kept eating the wrong things coming off of a fast forever after, I kept sabotaging what I had gained with the fasting . I realize that I had to get rid of the sugar and the carbs and that is so key. And with carnivore it is no sugar no carbs and no cheating. To be able to get the results that you want and to keep the weight off. my blood sugars are normal now my blood pressure is normal now my cholesterol is in a good spot, energy sleep good. Watch Dr. Fung’s videos on it, Dr ken Berry and Kelly Hogan is a really good influencer for the carnivore diet It’s hard to make the switch but well worth it, I just always keep in my mind that this is for my health and that I want to feel better and not have my arthritis hurt all through my body. And that has decreased 90%. But I am a strict carnivore to achieve this. Beef butter salt and water and I still do two coffees a day It’s so easy, it Has to be that your focus is not on food, it’s on the nutrition for your body and what is best. That’s what I have to keep in my mind and it is working and it has been 7 months Good luck and I wish you well
