Why Experts are Warning Against Fasting - Dr. Peter Attia, Dr. Rhonda Patrick, Dr. Gabrielle Lyon 

Here’s my newest FREE Meal Plan (High Protein Mediterranean with some Intermittent Fasting)- thomasdelauer.com/MediterraneanFasting/ Please enjoy it as a thank-you for subscribing to my channel and my newsletter!

Whilst you're fasting someone is losing money . . . . .

Meat was good. Meat is bad. Eggs were good. Eggs are bad. Fasting good. Fasting bad. I've been doing all three since I saw a video you did on fasting years ago. I'm the healthiest I've ever been. Went from 230 to 200. Remember, there's no money for big pharma when people are healthy.

Everyone stay calm and just wait six months everything will change again and you won’t have to change anything

Thats like: coffee is good for you, coffee is bad for you... I just continue doing my 18/6 intermittent fasting because I lost 30 lbs and I feel great.

It is worthy. I am 73 years old and living proof of it. I have been fasting for the past 20 years without any negative side effects. I fast 16 hours on and 8 hours off. On Saturday and Sunday up to 20 hours. I do not take any medications of any kind, not even Tylenol. The last time I had a cold was in 2002. I exercise daily from 0500 to 0600 hrs, do not feel fatigue, tired; rather, full of energy ready to tackle the day by standing up to 8 hours dispensing medications to people my age and much younger. I practice good eating habits and take my supplements. There you have it. Not bad for an old fart

Started skipping breakfast go to gym on empty stomach best decision I ever made

Well, I am living proof that my weight was 290 lbs. Now I am down to 237. Fasting ,exercise, and eating smarter have changed my life.

For over 50 years the best single thing I can do for my health is a 3 day fast. Period end of story. Thanks

I changed my mind listening and watching these "experts". I watch and listen to myself.

I'm 60 years old, and people say that I look 47, I have been doing 16 hours fasting for 30 years, I eat chicken with lots of vegetables and some fruits and nuts and i cook with extra virgin olive oil, I feel great, never had any health problems and I will never stop fasting.

None of these experts referred to any medical studies for their recommendations. I’m accustomed to Dr Ken Berry’s and Dr Jason Fung’s always referring to studies to support ideas. I’m still wrestling with residual insulin resistance from decades of carb addiction. I’ll keep intermittent fasting.

The one permanent feature of science is that it will inevitably change , do what works for you!

If the "experts" claim it is bad for you, what they mean is their is no profit in it and fasting is good for you. Follow the money on the study.

"Fasting is the best medicine ever "

Thomas, you are mixing up what they are saying. Dr. Attia's stopping 3 and 7 day fasts is completely different from Dr. Patrick's skipping a meal. They are not talking about the same thing and you try to make it seem that they are talking about the same thing just because they use the term "fast". I stopped 3 day fasts because they affect my workouts, but I still do OMAD and have not noticed a detrimental effect from eating only once a day.

There should be a delineation between fasting for someone in already perfect health with lots of muscle (like these “experts”) and fasting for someone that’s overweight with insulin resistance. Nothing lowers blood insulin levels like fasting.

These people did not get ill and then experience healing themselves through fasting. I did. And it appears there are volumes more studies supporting fasting than the recent one or two no peer reviewed studies that suddenly don't support it.

So basically anything “experts” tell you, don’t take too seriously because it will all be proven to be the opposite years down the road… as long as they get the views and clicks on their videos is the plan.

The thing about fasting is that no one makes money from it. We always think about the food and snack corporations, but nearly all these "experts" have sponsors, or a product with their name and face on it that would break a fast if it's regularly consumed. Fasting doesn't grease anyone's palms.

Have you interviewed Dr. Jason Fung yet?

I fast since 2020 my food bills plummeted. Blood work best it’s ever been . Have a relationship with a beautiful woman 20 years my junior . Happy life 🎉

Brought you by the proud sponsors of protein powder!

Currently on a carnivore journey and I am definitely getting enough protein. Feel better than ever, I usually fast 16-20hrs a day and have 2 meals a day.

Fasting was the most mind-blowing "discovery" I made for myself (I put that in quotes because obviously I followed others like Dr. Fung talking about it). It was like discovering how I had lived in my own "Matrix", got to see it from the outside for the first time, and now I live outside of some unknown prison I had lived in for 40 years (the belief that I HAD to eat). Fasting changed my life utterly, both as intermittent and as the prolonged version. It's one of the most powerful tools available to us, along with what we chose to eat, how much of it, the exercise we chose, and the mental stress we place upon ourselves. Play with all the variables, discover what works for you (and it's fluid - what works today may not work in 10 years as you age and can't do some exercises, for example).

THEY SAY FASTING IS BAD TODAY, BUT IN 9 MONTHS, THESE SAME EXPERTS WILL SAY FASTING IS GOOD.HOW CAN FASTING BE GOOD FOR YOU YESTERDAY, ACCORDING TO THE STUDIES, AND TODAY ITS BAD FOR YOU.

I fast. I rarely eat before 1pm. I maintain a healthy weight, I feel good and I am not hungry. Sometimes I don’t eat until dinner, depending on my activity level or energy level.

The reason fasting is dangerous is the food companies aren't making any money when you are fasting.

All of these people are fairly lean to begin with and they train hard compared to most. I think you should talk with Jason Fung. His clinic uses fasting for insulin resistant metabolically challenged overweight people. Fasting works best for them to improve their quality of life in every way.

As a Type 2 diabetic, I will keep on with intermittent fasting with a keto diet! Great interview with so many guests. Thanks for your help.

When the “experts” say you’re wrong, then you know you’re right. Keep cracking Thomas 💪🏼

Most people eat too much ' fasting is not skipping meals just going longer without food '

I think they need to define/clarify their use of the term fasting. 1. Are they referring to intermittent fasting? (Eating only within a specific time window each day?) 2. Are they referring to OMAD (one meal a day?) 3. Are they referring to 24 or more hours without food? Etc.

You need to interview Valter Longo, Mark Matson, Jason Fung and other people who knows more about fasting, mTor and AMPK and cell signaling pathways.

Treating diabetes, cancer, and Alzheimer's is Big business. If "experts" recommend something, find who's sponsoring and act accordingly .

8 years fasting and I feel the best ever. I am tired of these so called experts like Attia and Patrick and their waco studies and conclusions.

I'm 60. I regularly do 18:6 fast. Sometimes this is done by skipping breakfast, sometime an early dinner/late lunch at work at 3PM, then breakfast 9AM. I work out 4 times a week, 5PM weekdays, morning on weekend, and always eat plenty of protein after I work out, meat and plant. Any other times I stick to mostly plant-based proteins. DESPITE FASTING, I HAVE GAINED PLENTY OF MUSCLE MASS! So much, that is is obvious in the mirror. I am not competing in any sports, so really how much muscle does one need, if one is obviously very muscular? When I did a 4 day fast I did lose muscle, but I got it back soon enough. So I do a prolonged fast only a couple times a year just to hopefully get into autophagy. Fasting is the easiest way for me personally to keep off the fat. My priority of low belly fat and sleep well (I can't go to bed too hungry). Since I lost weight this way five years ago, I no longer have heart palpitation or puffy feet!

All I know is this: Due to 18-hour fasts on a daily basis, I was able to lose over 30 pounds in a 4 month period. In addition to the weight loss, certain biomarkers improved significantly (i.e. cholesterol, blood sugar/insulin resistance, blood pressure). Not to mention better energy levels and mental clarity. So, considering all of the benefits mentioned above, I will continue with my daily fasting protocol. Naysayers or individuals that no longer fast will not deter me from continuing such a practice. 👉💯🧘‍♂️🙏☯️

Fasting is a spiritual discipline that is taught in the Bible. Jesus expected His followers to fast, and He said that God rewards fasting. Fasting, according to the Bible, means to voluntarily reduce or eliminate your intake of food for a specific time and purpose.

Peter Attia took something to the extreme and STILL after 3 years only lost 10 pounds of muscle.

I used to rabbit hole on RU-vid about health. For many years. Now ignore everything.

They done made their money from fasting now it’s time for them to move on. SMH

Call me a rebel, but I do what I want and what suits me. Period. The only "expert" on my health is ME.

All these experts that are going against fasting are very healthy and fit. They don't need to fast and hence why they might find fasting detrimental. They don't have much fat to lose. For those of us who have a host of metabolic conditions are are overweight, fasting is still probably highly beneficial.

I am not so sure that they are warning against fasting. What I am seeing here are suggestions to be more mindful about protein when considering or engaging in fasting. For instance, suggesting being cautious about skipping breakfast is not suggesting against fasting, it may simply mean having your feasting period earlier. Eg. I used to have breakfast around midday and my last meal around 7 or 8 in the evening. I now have breakfast around 7 or 8 am and my last meal around 5pm. Then I saw the suggestion that prolonged fasting need not be frequent. I don't see warnings against fasting generally

I did IF and went from diabetic to an a1c of 4.8. I backed off a little bit on IF (down to 4 days/wk) and gained 25 lbs and inflammation increased. I'm going back. I would assume these people aren't prone to metabolic issues.

Fasting has been practiced in many religions for centuries ❤ Jesus fasted for 40 days and 40 nights to be more pure. Fasting is healthy ❤

Enjoying this part of your channel Thomas, not just the interviews, but combining several into specific themes. Good stuff!

Very informative. Thanks for all the time and effort you put into collating and discerning the truth. Much love, brother 🙌

The biggest take away is that fasting can be a tool to use, but make sure your not excessively straining your body with multiple day fasts. Intermittent fasting seems fine as long as you are getting enough protein and rest to recover.

Anything, taken to the extreme, can be deleterious. If you consume too much water you can induce hyponatremia, which can be fatal. Should we, therefore, consider drinking water as dangerous? Absolutely not. Similarly, fasting can have benefits, but it must be done in such a way as to not induce significant muscle atrophy it can be problematic.

Fasting is good for people I eat breakfast but finish eating by 4pm/ 5pm I’m only eating 2 meals a day and feel great at 61 my skin is glowing.

We Americans, for being the unhealthiest people in the industrialized world (still edging out the U.K.), are obsessed with the most esoteric and obscure food regimens. I stopped eating processed and fast foods and dropped 20 pounds without any further effort. It’s really that easy.

I just don't think we are designed to eat all day. The only animals that do this are herbivores. We do need plenty of protein for sure but do we need to be eating it all day long?

How many times do you think "experts" can tell us to do the exact opposite of what they espoused previously, before we come to the understanding that we're being manipulated? I'll tell you in my case, that moment is now. Thanks for the memories Thomas. I wish I could say it's been fun.

really appreciate that you compressed all of this info into 1 vid

Skipping a meal is just that. Going on a fast should not be stressful, if it does make you stress, dont do it. Experts are always changing their minds. Its getting ridiculous. Skip the sugar, eat when you are truly hungry and enjoy your life.

Excellent Post Thomas. I’ve listen to all those people, but don’t have enough time in the day to be up on all of their personal research. I luv the way you utilized all of them into one well done analysis..

The whiplash. I can't keep up. I feel great while fasting, so I frankly don't care what they say. 😂

This video focused a great deal on muscle mass, and I get why that's important, but what about those of us doing 16:8 in order to improve insulin sensitivity?

I think it would also be important in a video like this to address people who may be fasting due to certain medical conditions. All of the people in this video were fasting to optimize health.

Dr. Lyon saved my life with her protein suggestions. I was going through perimenopause and one of the best remedies to relieve symptoms was significantly increasing my protein. I will add that you, Thomas, sold me on iF and that relieved Perimenopausal symptoms, too.

I like how the term "expert" gets thrown around --there arent any in a field with more questions than answers

I've been doing a 16/8 fasting protocol for years. I am 67 and feel like 45. I consume organic foods, wild blueberries, apples, greens, onions, organ meats, regenerative pasture raised eggs, Bison, Elk and other healthy proteins. I switched from doing intense fasted workouts (due to excess cortisol levels) to fed weight training, and have actually increased my strength. The world record for 198 lb squats is only 365 lbs for the 70+ age group. At 67, I have done 465 and plan on shattering the record by age 70. It is ALL about strength for longevity. Your body watches your "Vitality" and produces hormones to match. My motto... "Don't let the old man in!".

Great video. Putting all those experts together in one place like that. Nice job, Thomas.

The video featuring Thomas DeLauer discussing expert opinions on fasting, including those of Dr. Peter Attia, Dr. Rhonda Patrick, and Dr. Gabrielle Lyon, offers several key takeaways on the reconsideration of fasting practices: 1. **Shift in Expert Opinion:** Many health and fitness experts who once advocated for fasting have revised their views based on emerging evidence and personal observations related to muscle mass preservation and overall health impacts. 2. **Concern Over Muscle Mass:** A significant concern among these experts is the potential for muscle loss during fasting, especially with prolonged periods without food. Maintaining muscle mass is emphasized as crucial for health and longevity. 3. **The Importance of Protein:** The discussions underline the critical role of protein in preventing muscle breakdown. Adequate protein intake is essential, particularly after periods of fasting, to support muscle protein synthesis. 4. **Revised Fasting Practices:** While fasting can have benefits, these experts suggest modifications to fasting routines to mitigate negative effects, such as focusing on sufficient protein consumption and timing workouts to preserve muscle. 5. **Protein Intake Recommendations:** For those engaging in fasting, a higher protein intake than previously thought necessary is recommended-ranging from 1.6 to 2 grams per kilogram of body weight-to support muscle maintenance or growth. 6. **Exercise and Fasting Compatibility:** Resistance training is highlighted as beneficial during fasting periods to help counteract muscle loss. Proper nutrition, particularly adequate protein and calorie intake around exercise, is crucial. 7. **Balanced Approach to Fasting:** The experts advocate for a balanced approach that incorporates fasting into a lifestyle that also prioritizes muscle preservation through diet and exercise, rather than fasting in isolation. 8. **Fasting is Not One-size-fits-all:** The evolving perspectives of these health experts reflect a more nuanced understanding of fasting, recognizing it can be part of a healthy lifestyle if properly managed, especially in terms of nutrition and physical activity.

For me fasting is life saving. I'm pre-diabetic and very overweight. With severe insulin resistance. No matter what I've tried including a GLP one I cannot keep the weight off. So I put myself on a strict keto diet and started intermittent fasting. But I'm doing this to heal a body that has been under stress for a very long time. So for me while keeping the muscle is important because I'm an older woman it is also important that I get this weight off and don't go down the road of diabetes. So for those of us who are not at a healthy weight or not at a healthy point in our lives fasting might just be the thing we need.

I intermittently fast 6 days a week for 18-22 hrs, weight training and cardio fasted also 6 days a week. My weight consistently is around 240lbs, muscular and lean. I do not track macros, simply focus on protein intake and moderate carbohydrate consumption. I’m so tired of the experts stating you lose muscle, catabolic state kills performance. I have more energy, strength has improved and my natural testosterone levels remain high. I feel and look amazing, better than I did in my 20’s….I’m 44 this year.

This one was really good Thomas -thanks.

They want you to eat fast food And never fast from food

I haven't eaten before noon for over a year and am in excellent shape, with strong muscles, workouts, and protein!.

I used to watch most of your stuff and liked it. You are floundering here lately, I wish you well.

Some people are overly focused on losing weight fast. It can easily turn into an eating disorder and obsession. They become weak, lose muscle, and they are anxious all the time. They start to believe they look healthy.

Just sick of these so called experts. Give it a few months and they will all be saying something different. Next week, we were wrong about SAD. Ultra-processed foods are good for you.

There was also a video stating cold plunge like what Joe Rogan was doing was actually harmful in the long run. There was an actual study proving harmful effects. Now I am also skeptical about this long sauna Rhonda is advocating.

I have been doing either 16/8 to 18/6 for over six years, I am soon to be 60 in the best physical shape I have been.

Everyone takes things to extremes; except the people who don’t

Fasting is neccesary for a specific group of people. Wisdom is 'nothing works for everything' so yes, fasting might not be for everyone, . However only the ignorant denies the benefits of fasting on re-setting cellular activity. Thanks.

Where's the study that corroborates the theme of this video? There's no shortage of fasting studies

Thank you Bud!!! You are helping me soooooo much with your clear and dynamic videos. Love it and love you Bro!!! Abrazo from Mexico City!!!❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

It amazes me how little these "experts" know about nutrition. They claim this, then they claim that. This, that, this, that. Like Paul Saladino, he changes his mind every 3 years.

The best benefit of fasting is that you lower anxiety and dettach emotions from eating, so you are not associating bad or good feelings with food, so you feel really liberated, you feel control of yourself, pain is not that bad, fear is gone. That alone is worth of it.

I am almost 72, insulin resistant, down about 90 lbs doing KETO but still need to drop a few more. I need more muscle mass....was never an athlete. Sticking with two meals a day until I have a normal A1C, etc. I eat breakfast and have a second meal early afternoon....about 2:00. In the gym 3 days a week with resistance training. Will start daily brisk 2 mile walks when weather gets better. Your posts seem to be addressed primarily to people whose profile I don't fit.

Fasting has changed EVERYTHING for me. When I adopted a whole food no-grain/sugar/seed oil diet and then finally added an OMAD approach to eating, my health has completely transformed! I am a retired trainer/weight-lost specialist and fasting has helped me drop to my leanest weight without overtraining. For me it’s the true solution. I do focus on clean protein, organic vegetables, butter and single-source olive oil in that exact order and at 67 I’m the healthiest I’ve ever been.

Such an interesting video !! Wow thank you so much 🙏🙏🙏

Thomas, I appreciate the content you put out so much! I’ve been listening to you for years. You always seem to be in connection with the other experts I follow. Thank you for the information you provide and the research that you do!

That's why you focus on high protein keto while fasting. The first doctor shown here has gained at least 20 pounds and is beginning to look unhealthy.

Thomas did such a great job representing everyone he interviewed. Thats a lot of trust from all the other experts interviewed. Thanks for the daily motivation!

One unexpected thing I noticed while fasting was the amount of money I was saving not buying as much food.

I've always felt that it is super easy to regain muscle after fasting. I water fast for usually 4-7 days a few times per year, and no question, you do lose some muscle. But within 2-3 weeks, I'm back to making progress at the gym. Sometimes you have to take one step back to propel you two steps forward.

I watched the original interview with Dr. Patrick and found it curious at the time that she didn't change her mind because of new science, but after "talking to experts".

Great! Thanks!

Great video here

I like that she said 'skipping meals' what does thst mean, who decides thefe should be 3 meals and day and if you do less your skipping a meal or adding of you do more.

Western diet has been mostly carbs, some lettuce and protein and more sugar. Sounds like the diet world is still lost, imagine that.

I have to agree; at 61 (now 63), I began Keto (which saved my life; long story), but I didn't know about the increased need for protein. With multiple 2 and 4 day fasts I lost a lot of fat AND lean muscle; the latter which I had from my many years of working out as a younger man. Now I have a shoulder issue because of it; still trying to recover. So I take creatine and have upped my protein; doing mostly carnivore diet with some fasting on the weekends; "flexing out" of Keto (per Keto Kamp's channel); often doing two small meals and a big one - with some carbs once or twice a week.

Don't listen to any "experts", listen to your body. Fasting makes me feel good, that's all I need to know.

Fasting saved my life while I almost got diabetes 3 yrs ago , but i do notice that my muscles decreasing after my weight back to normal

Havnt watched the video yet. However, 7 yrs ago I began fasting, lost about 30 pounds, 6 2’ 225 to 195. Omad. I had abs, probably lost alittle muscle. But you feel so good! Next time I would eat protein during the day.

This is one of your best videos… fast and to the point with all the videos… love it.
