New study - Intermittent fasting doesn't work

A new study claims that intermittent fasting doesn't work for healthy weight loss, but not so fast! As we look at the details of the study, its limitations are significant and we have to be careful how we interpret the findings. Do they apply to you? Let's find out in our latest DD News video.

Who does a study to see if IF works for weight loss by using lean subjects?

[@Minnasification]

Nope. Conflict of Interest Disclosures: Dr Lowe reported personal fees from Keyto outside the submitted work. Dr Vittinghoff reported personal fees from UCSF during the conduct of the study. Dr Heymsfield reported personal fees from Medifast Medical Advisory Board and personal fees from Tanita Medical Advisory Board outside the submitted work. Dr Weiss reported grants from NIH, grants from James Peter Read Foundation, nonfinancial support from Mocacare Inc, and nonfinancial support from IHealth labs during the conduct of the study; he also is a cofounder and equity stake holder of Keyto, Inc; and owns stock and was formerly on the board of Virta, Inc. No other disclosures were reported.

[@BlueBlueFeelin]

@@Minnasification That looks like a lot of potential points of conflict! Keyto is a company with a Mediterranean style keto diet product, for instance, and they may have interest in keeping people eating every day, within ketogenic parameters. Plus the nature of the study is pretty useless, you must admit. Fasting for weight loss is advisable for over weight folk- not the participants in the study. Yet the headline is that fasting may not be optimal, when no conclusion was ever reached. So when you said "nope" what you you meant was "nope, not a major food company". Just smaller ones...

Actually it wasn’t. When you fast it is your glycogen storages that are emptied aka water weight. IF promotes binge eating disorders. It is a FAD diet. Eventually your will power will give out and you will binge eat. In the real world on the real solar system on this real planet, the law of thermodynamics holds true. Calories in calories out.

[@bunny_0288]

@@breddf347 I mean it may be a fad diet for some, but it is my natural eating pattern. I've never enjoyed breakfast, but I ate it because it was the "healthiest meal of the day." I've never really been one to snack after dinner unless I was with other people. My body naturally likes to eat between about noon and six every day. I've only started this week, but it isn't even a challenge. I'm also counting calories though because I know that I can easily pack away quite a bit of calories in those 6 hours if I'm not careful lol. It's good for your body and digestive system to take a rest and not be constantly working all day long. I personally would rather sit down and have 2 decently sized meals a day than try to spread my calories out and have 3 meals and a snack with the same calories. For me, that's a recipe for overeating. Now I can sit down and have a wrap and a piece of fruit for lunch. If I'm hungry, I'll eat a small snack and have some tea with no sugar in the afternoon and then I eat a fairly "normal" dinner. I've already lost a couple of pounds. And maybe calorie counting alone would produce the same results, but in the past I was hungry all day with calorie counting. With IF, I actually feel comfortably full and satisfied because I'm able to eat decent sized meals. We'll see where this goes, but I personally really enjoy this way of eating. It feels completely natural for me.

Then I tried intermittent fasting and after a decade of trying to lose weight I was finally able to. I’m only one person but I’m convinced that for me cutting calories just doesn’t work. And if it’s true for me it’s probably true for others. Also I have a six hour feeding window. I tried omad and lost a lot of weight but it wasn’t sustainable. Plus I found that I can put on muscle better with more protein that I can get eating two good meals a day. Very happy with intermittent fasting. I have no plans to ever giving it up.

[@ndt270]

@@davidsink3887 Hi David. N is the scientific abbreviation that stands for the study population for a research study. In the case of many research controlled trials, there may be thousands of participants in the study, and for example, if there were 10,000 people in the study, N would equal 10,000. For those of us who have chosen to forge new trails into things like lchf or carnivore, we are few in total numbers and we have to be very dialed into our personal responses to things like changing how much fat we consume, how much protein we have added or reduced, whether we have eliminated vege tables, supplements we may be taking, and many other variables. We are individuals and don't all respond to a simple formula. I may respond positively to high protein and less fat, but someone may be opposite. I think this beautifully and simply indicates that we all have to take personal responsibility for finding our optimal health which, although has much common ground, varies to a degree for all of us. As to the second part of your question, I have been very interested in health and nutrition from a very young age and started researching the carnivore diet and adopted it a few years ago. Dr. Shawn Baker and Dr. Paul Saladino recently authored very good books and I decided to experiment with their propositions, and the results for me have been better than I expected. We all walk out own paths in life, and David, I think the most interesting thing about our lives, is that we have immense influence in our health and happiness if we will just accept our responsibility and capacity to accept it. Live long and prosper!

I think a lot of studies are DESIGNED to fail, like the first one you mentioned. Something that doesn't get mentioned enough about time restricted feeding, is the fact that it gives your insulin levels time to come down. You simply can't lose weight when your insulin is high, and typical eating patterns, especially with the high carb feedings, keep insulin high and create pathology in the human body apart from that caused by high blood sugar. (recommend Ben Bikman and Jason Fung).

There is so much contradicting information out there. Keto works, keto doesn't work, IF works, IF doesn't work, dieting doesn't work, diet works lol

[@dr.samierasadoonalhassani2669]

Shocking titles,contrarian views ,contradictions is not good for our stressed mental health.

[@rayprusia4753]

I started IF and it works. It has changed my relationship with food, and I feel great. I have lost 30 pounds since I started in March, and I believe I can do this for the rest of my life. It a lot easier than a diet.

[@sujathat4913]

Who told you that.i did if for 3 months and still doing and I lost 8kgs ! 74 to 66 .very energetic and happy.

[@thebadger9302]

At the top of any of these studies should be the group funding it. There will be the answers.

[@finncustomtile]

That study said alternate day but the title says intermittent...those can be two very different things. Strike one and I’m only 80 seconds in 😂

[@hopefull61256]

It is a form of intermittent fasting

[@darkchocotony3391]

People who bash this video just read the title but did not watch and understand it. The speaker DEBUNKED the new study. He actually DEFENDED intermittent fasting and explained why the new studies against it are inadequate and misleading.

[@rjjrdq]

I tried the 16/8 if protocol and was hungry alot. I ended up shoveling down more food in the 8 hour window than I normally would eat. I gained weight and had to stop.

[@BobbiDoll]

When I had seen the headlines I thought what a disservice to people who needed to lose weight and gain control of their metabolism. I am so thankful that you addressed this.

[@nocarbsnation]

Interesting. For me, I guess I over simplify my strategy. I listen to my body. I eat when I am hungry (typically twice a day), and I eat until I am no longer hungry. It's what I eat that has been the difference. I am firmly against calorie restriction. I used to be in the 240's. I have now maintained weight in the 180's while eating as much as I want (when I am actually hungry), and doing so in my late 40's. I think we tend to overcomplicate weight loss and bettering our health. Went from obese to maintaining my HS weight, reduced A1C from 10.5 to 5.3, and a laundry list of of other positive health changes. Just my 2 cents from my own experience. I also believe everyone needs to do what is best for them.

[@SgtSlime365]

I’ve lost so much weight and I truly feel 10x better. The amount of energy I have is amazing

[@tomandersen7343]

Please! Keep on with this translation of headline-science - I love it!

[@KillerofGods]

IF/Keto has truly changed my life. Went from 213 to 163 from the middle of feb to now (beginning of august.) Lost a good 35 pounds from late may where I went from cutting back carbs to full on keto and IF. Highly recommend to anyone considering trying it out, also no need to switch over immediately, you can slowly let your body adjust as I did...

[@happyapple4269]

There has been a new study since this one saying it does work. Keep up.

[@MrLeebooher]

People I've known for years don't recognize me anymore, My 99 year old Grandmother that has 20/20 vision didn't so that 1% can be ignored.

[@lorettadillon-ham1574]

Brett you really are brilliant! 🥰👍🏻

[@drSamovar]

If you're a medical director, and you would like to be taken seriously, you may want to consider NOT using clickbait. For the tens of thousands of us for whom IF has had a long list of real-time benefits, we are unlikely to even give it a listen.....canning the clickbait would up those odds....

[@twofarg0ne763]

I'm 71. I was 238 pounds, borderline diabetic, and had high blood pressure. I started IF in Feb of 2021. By the end of July I weighted 200 pounds, blood sugar was normal, and so was my blood pressure. I eat twice a day (everyday); once at 1:30pm and once at 5:30pm. 90% of my meals are keto and 10% are whatever I want. IF works. I will continue this regiment as it is now a habit.

[@ernestrodgers789]

It works for me because I eat 500-600 fewer calories per day just by doing 16:8.

[@alphacause]

Lean body mass does not exclusively refer to muscle tissue that produces the strength you need to be mobile and functional. It could also refer to supporting structures, like extra connective tissue, extra organ size, extra bone mass, extra skin, which were all needed to support a larger body when it had extra adipose tissue, and extra leg muscle to support a previously heavier weight, which are now superfluous now that the fat mass is gone. So loss of lean body mass, in the course of a fast, does not necessarily entail a loss of strength RELATIVE to ones newer lower body weight

[@chrisucl]

Worked for me. I lost 8kg and improved cholesterol from 260 to 200 and A1C from 6%to 5.2%

[@WH-hi5ew]

Doing 16:8 I went from 193lbs at my heaviest to 194lbs now... from 36" waist to 32". Feel much better for this and won't be going back to previous way of eating.

[@ritevibe]

huh?

[@zondakaymusic5145]

How can I report this?

[@Rob_430]

I’m 75 and doing IF for over a year, 18/6. I don’t miss breakfast, and I’m keeping the weight down. Less meals to worry about, especially since breakfast is either eggs or carbs.

[@tke2414]

I lost 120lbs eating Keto and OMAD. I've been doing it for about 10 months now. I eat a little more on the weekends usually having a small snack at some point during the day and then eat my normal meal in the evening. I have never counted calories since I started. I only count carbs. I went from 300lbs to 180. My A1C went from 6.5 to 5.0. My triglycerides went from over 600 to 85. Total Cholesterol from 241 to 158. At 58, I have more energy than I've had in decades. I will never eat any other way ever again. I'm not saying I won't eat the occasional pizza or dessert, but they will be the exception and not the rule. Eat food like it's medicine or you'll end up eating medicine like it's food.

[@ejdaddy3161]

doc can you explain to me the authopagy with fasting? are funded by them?

[@DaKidwitskills]

Worked for me. August 2020 : 243 lb September 2021 : 168 lb

[@parsoniareigns]

Hmmm....in lean adults..

[@davida7559]

I’m struggling to do it because once I work out I get hungry and can’t go for long without food. Maybe something is wrong with me

[@nosom7]

It worked for me.. but we have to follow certain rules with that

[@evelynsalinas4852]

Lies!!! Fasting does work. I’m living proof, and so is my sister. Feeling so much better. Lost 60 lbs. my sister has lost over 80. The ketogenic diet plus intermittent fasting is the best thing you can do for your body.

[@ElizabethUkeh]

Thanks for analysing these studies that try to confuse us!

[@jenwhite8832]

Why are these studies always so different from the reality of people’s experiences? I work in a scientifically focused field, and the most challenging part for me is seeing studies that I’m meant to be building my work on being completely removed from real life

[@endthedrugwartoday]

I love day 3 of fasting when you realize that everything about fasting is so true, and Thank God you got to feel this good in life. The desire to be without inflammation will see you through to the next 60 plus hour fast.

[@kodowdus]

My guess is that muscle mass can be maintained in a lot of ways regardless of the ratio of carbohydrates to protein in the diet.

[@littlevoice_11]

Please release a new video on the perfect protein and macros on a low carb diet for overall health when combined with I.F. I do I.F. to optimise improve blood sugar control, cognitive function and anti aging rather than lose weight. Maybe a video on the best I.F. pattern for different aims e.g weight loss, diabetes, body composition, muscle growth, digestive health, autophagy etc. OMAD, 5:2, 16:8, 20:4 or FMD? I.F. is such a broad term and needs to be defined more clearly in these research reports. I'm so pleased you covered more than just the misleading headline.

[@domizzi626]

I’ve been doing IF, 16/8 most days and in 4 months I went from 238 lbs to 195 lbs.. I’ve stagnated a bit, but at least I’m in a better position than I was 4 months ago. I take care of what I eat also. I stay away from refined carbs, sugary drinks, fried foods, processed foods, so that has helped.

[@missdaisydoodle]

Thanks for being a voice of sanity in an insane world.

[@deborahmiller1925]

I think dr. Jason Fong is world-renowned you want and is correct in his findings on fasting

[@BlueBellGoPro]

I fast and I am 42 years old , still performing exercise at a high level and 7% body fat. The technique does help me eat less as I have less time to eat but something else is at play during my fast as my exercise and sports performance is so much better on a empty stomach.

[@steveb9713]

Who paid for that study sounds biased af

[@ghostedyoutuber263]

30 lbs later, i find out fasting does not help... well... okay then... I will continue to fast until I don't lose 60 more pounds. Then after 90 lbs of weight loss... I am so glad to find out that fasting does not work.

[@Michelle_with2Ls]

I appreciate you taking the time to break down the study so that people who choose to be are better informed. I am a big fan of this channel and love watching the interviews. Thank you all for your contribution. 🙏
