When they are disrupted, individuals typically have an increased risk of metabolic disease and diabetes. Research on how fasting (and how much fasting) can promote a more robust circadian rhythm is still very much developing, but some animal studies suggest the benefits may also include improved sleep and longevity. Intermittent fasting can be a safe choice for weight loss, but it all depends on how you approach it and how your body responds. Fasting is not for everyone and you shouldn’t try intermittent fasting if you are pregnant, diabetic or healing from a traumatic event such as surgery. “The evidence that intermittent fasting benefits the health of overweight people is already very strong, and its potential to slow or reverse certain diseases looks very good,” says Mark Mattso.

In terms of your physical health, intermittent fasting isn’t necessarily harmful to your body. Calorie reduction, achieved by this practice, could benefit your waistline. However, it’s been noted that some folks may eat more than they intended when they break a fast, thereby counteracting the desired effects.

Dieting is the #1 cause of the onset of an eating disorder. So, even if it had been proven that without a doubt intermittent fasting would improve health (it most certainly hasn’t), I still wouldn’t recommend it because it’s not worth slipping back into an eating disorder or risking the development of. Intermittent fasting, like most other diets, can be hard to stick with.

In a study conducted at Harvard, 38% of participants dropped out ( 2 ). This is reflective of real-life because IF can be a. It may also help boost metabolism. A 2017 study suggests that intermittent fasting leads to greater weight loss and fat loss in men with obesity than regular calorie restriction. Research from.

Proponents say intermittent fasting is a safe and effective way to lose weight and improve your health. “Intermittent fasting is an umbrella term for. Intermittent fasting is officially more than a diet trend. The eating regimen has exploded in popularity, largely because of what it doesn’t require: counting calories, tracking macros, labeling foods as.

Periods of fasting less than 24 hours (20 hours fasting, 4 hr eating) or ‘Warrior’ style fasting can be done daily. The term ‘healthy’ always depends upon what your goals are. If you are simply trying to lose weight, then fasting can be done as needed for that.

On the other hand, one should not fast for more than three to five days unless he is under the care of a physician who does understand and believe in fasting, or someone equally experienced.

The point of intermittent fasting is to prevent the body from producing insulin—therefore, no food should be consumed during the fasting time.

  • It would be cool if you could do a video on what everyday foods we can eat at the end of a fast. There are lots of videos on what not to eat and some that promote things like seaweed and bone broth but not everyone has time to cook up a soup during a work day or lots of money for healthfood shop items. Some simple ideas would be great. Thanks

  • Sir.Hats off to people like you.I pray that God will give you wisdom to do more such videos for the well being of the people.��������

  • Can you exercise normally while intermittent fasting or should we do them on off days. I’d also check out Doctor Oz’s website. He has spoken on fasting before. I know you can drink water on fasting days. Is it contradictory to what your talking about with the water weight here.

  • you don’t overeat. you just break your fast (18-24 hrs) and you eat a simple meal you would normally eat preferably healthy. Then you eat how you would usually eat the rest of the week. its very simple

  • IF is not a diet first and foremost Second withdrawing food for several days is not intermittent fasting. You can’t say you like what this correspondent does and then say IF is bad. Totally misleading with blanket statements about IF.

  • I’m into fasting because is this stric.
    For me the problem of other diets is that “allow” me to eat any time. And when I start I can’t stop.
    This help me to don’t monitore my hundry/craving every minute, is stressful. But with IF I don’t have to worry about it.
    Other wise i binge out of control.

  • I am a 57 year old insulin sensitive woman?What if I have hypoglycaemia incidences?Should I fast 16:8?Should I take medication for it?

  • I basically eat every other day, and when I do I consume a good amount of calories.
    In other words, when I eat, I eat on a slight caloric surplus, and then fast for 36 hours. Once you hit the 18-24 hour mark, you’re running on fat for energy, so the next 12 hours until you eat, you’re just burning pure fat.
    the caloric surplus helps muscle regeneration so the muscular loss is basically nonexistent.
    I try to do 3 36-hour fasts every week but sometimes I only get 2 in.

  • This question is perfect. When i was a teen i had an ED. Today i have 38 years old and after having my baby i gained some weight. I started IF on August last year and lost 10 kg, I’m really short but i have 46 kg, i’m too thin now and i ‘m terrifyed of gaining weight. When I started IF i was very happy and enjoying myself, but now I don’t know��

  • Really interesting an dwell presented. I’m at ease with 16:8 but recently tried a couple of 24hr fasts and found sleep hard because my brain was racing not through hunger but just everything. Maybe it is just a bit of training and it will quiet down.

  • I have lost 120 pounds, 20 inches off my waist. So I did the opposite, I started eating 3 smaller meals + 2 snacks, I count carbs, eliminated salt, sugar and fat. My glucose went down from 550 to 85-100 my A1c was 5.2 last time I checked, I was starting to go blind and couldn’t read or see very well anymore because of the glucose. The dr already eliminated 2 of my 4 diabetes medications and told me we could eliminate even more if I keep it up. My cholesterol went down from 300 to 100, triglycerides down from 380 to 160, my uric acid is under control, my testosterone levels also increased. I eat about 2100 calories per day and walk 2 to 3 hrs per day plus light weights. I also don’t suffer from hypertension anymore or Cardiac Syndrome X as frequently. I had chronic migraines the worst one lasted two yrs 24/7, I have only had minor problems since then. I learned balance in my life.

  • Started ADF (alternate day fasting) this week! Watching, not counting, my calories on eat days. I find, with being in the beginning it’s hard mentally. My fridge and pantry are full! I wanna taste it all!

  • This is what I hate. A man promoting people to skip meals and deeming food as an enemy. Imagine a younger female viewer watching this… I just don’t understand how people are allowed to promote fad diets like this…

  • I am doing a 20/4 schedule with Sundays being a full day fast. It took about a week for my body adjust but now I don’t have hunger and my energy levels are normal. I do my workouts the hour before my first meal, which is 3 pm. I follow a keto diet when I break my fast and get plenty of nutrition in that 4 hour window. I drink a lot of really good water (not all water is the same). It is not a difficult regime and for folks that are healthy overall this should be no problem. If you are overweight then you can’t find a better way to burn fat, especially around the mid section, if you follow an intermittent fasting schedule and a keto diet along with exercise.

  • No restrictions. I can lift heavy, light or do cardio workouts. Cool!!
    I would feel uncomfortable doing it without drinking water. Staying hydrated is always essential. I was raised on water not soda or juices so that’s fine. I hate warm water though but during the workout I tolerate it. Thank you.

  • 10 years paleo one meal a day not good for the long term, high TC and LDL, high blood pressure, chest pain, etc. And weight increased 3 kgs in the later part of the period. Short term fantastic.

  • I’m 6’1 185 Pounds. I’ve been gaining some healthy weight for the last 4 months.. I would like to try IF 16/8, but I don’t wanna lose any weight. Is it possible to Gain or maintain my weight with IF??

  • If you cut your protein intake, it might be a sign that you don’t eat enough protein to rebuild your muscle tissues.. but the overall calories doesn’t affect muscle soreness.

  • Wondering about blood pressure. I’ve been on Bp meds for years, take my bp nightly. Now I seem to have low blood pressure since doing Omad. Wondering if the diet and bp readings are related?

  • All these so-called health professionals are stuck on this three meals a day thing! and he says that we are designed as humans to eat a coupleTimes a day, how does he know he didn’t create the human body life is about experimenting to see what works he’s not the only right person so he thinks, there’s way too many people experts! with varying opinions hard to tell what’s right and somethings doesn’t work the same for everybody either

  • Thanks for the info Lee. Suggestion, instead of saying “Eat less calories than you burn”…lets try “burn more calories than you eat”. Easier to understand.

  • I mostly do a 16:8 fast at least five days a week, occasionally I’ll manage an 18 hour fast. I feel so much better than I used to, no more sluggishness or brain fog ����

  • i’ve heard the advice to eat 6 small meals instead of 3 full meals is WRONG. True?

    i’ve also heard the advice that you gain more weight from dinner because you sleep right afterward is WRONG. True?


  • When I do IF, I end up binging later and actually eating more calories in a day and gaining weight! Everyone is different but I’m sick of hearing about these “magic” strategies.

  • Mate 5.15 in you talk about intermittent fasting and switching from carbs to fat burning for fuel but you haven’t discussed anything about the ketogenic diet! Intermittent fasting is one thing and the keto diet is something else, you are confusing people by your presentation.

  • I wonder why people still don’t believe in herbal treatments, I was on diet for good 5 years due to diabetes, this real weigh me down and caused serious depression. I later found @aluya_herbals on Instagram who sent me the cure, I have no sign of diabetes in me again. Don’t fall for scammers. check his handle for confirmation… Reach Dr Aluya on email: [email protected], WhatsApp: +2347031846539, Instagram: #aluya_herbals.

  • The white guy is racist and wrong!!!! He does not understand evolution I’ve doing 1 meal a day for 2 years with the best results and not suffering!

  • It probably depends on how your body reacts to fasting, but I personnally never heard about someone who passed out doing intermitent fasting.

  • Hi Autumn! Thanks for all your info, it’s really amazing information that is helping me to make the correct nutrition choices. I’d like to know what your thoughts are on ‘juicing’ like the extraction of fresh fruits and veggie combinations daily. I know about celery juice but what about having these everyday? eg. Beet, carrot, apple, ginger, turmeric? (Obviously it’s better to ingest for fiber reasons) Thanks:)

  • I wasn’t expecting him to take the stance that he did, but I’m very “impressed” with Lee’s knowledge now. I think it is evident that Lee actually researches what he makes on and doesn’t subscribe to things of the past like 5-6 small meals a day. He also knew about the various types of intermittent fasting and doesn’t say that you lose muscle if you don’t eat for 2 hours. Good job Lee, hope you read this.

  • It’s not “auto-fay-g” it’s “aw-toff-o-g” in both US and UK English.
    Anyway, my baseline is 16:8, although when I can prolong that by an hour or two I do, but still make sure to take in the same amount of calories. Fasting isn’t a license to eat as many calories as you want within a specific window. Might try going for a 24 hour fast where I still end up eating 500 or so calories, but so far my limit is nineteen and a half hours.

  • This was great!!!! I’ve wondered about this question as well since I’ve struggled with eating disorders in my past. Thank you������

  • I’ve been doing 12-16/8 for 2.5 weeks. I still feel uncomfortably hungry. I’m not trying to lose weight, just trying to be less carb/food dependant for practical reasons, i.e. tired of having to eat all the time, and when it’s not convenient.

  • Dr Vijayaraghavan. Sir, You are blessing of God for huminity. Sir Please give the alternate of wheet, Rice and it should be free of gluten and Carabs. So that Could be free from (Cure) diabetes. ۔…… Thankyou.

  • I don’t understand why people like the every 3 hour eating. It’s fucking uncomfortable and inconvenient. I’ve also noticed that it messes up my digestive system. I’ve gotten better results with intermittent fasting.

  • I’ve been IF for six months now. Generally eating one meal a day for 2-3 days in a calorie deficit, then I have one day off where I eat two meals or so and I have my cheat meal then back in again. Works for me. Helps me eat healthier and continue to lose weight

  • This “Dr” does not know what he’s talking about. First Keto, I lost 40 LBs in 4 months. Now I’ve been doing OMAD for almost a year and it has trasformed my life.

  • CBS! People have been fasting for thousands of years.. Back in the day they lived to ripe old ages.. Fasting is good for the body in moderation. NOW FRUCTOSE CORN SYRUPS AND GMO’s! They are deadly. All of the boxed foods and GMO produce is deadly. Why dont you do a piece on Monsanto Bayer or Dow..?
    Oh thats ok i know you would never anger your sponsors..

  • I found it easier to naturally fall in the 16:8 pattern. I somehow have very less inclination to eat in the morning. I do have 2 cups of tea with sugar and milk though, and 2 cups of green tea without sugar or milk. In the afternoon I break the fast with high carbs meal and fruits or salad. In dinner also I eat a high carb meal. I am loosing weight. I seem to be retaining the muscles. I work out 3,4 times a week.

  • IF is not a diet; it is a life style. IF is not a fad. People have been fasting since the beginning of time. This doctor obviously does not fast. He is a little overweight. The medical community has been giving alot of bad advice.

  • It would help your credibility if one pro wouldn’t completely knock out another one. Keto and cheap are two completely incompatible properties. Avocado, fatty fish… every single source of non-dairy fat for keto costs an arm and a leg.

  • I practice “intermitent fasting” but no pattern. I skip breakfast unless I am doing a lot of exercise in the morning and sometimes I skip dinner. I have never been fat, but I started skipping breakfast at age 17-19 just because I didn’t care for it. Now I have discovered it is a thing.

  • I am new to the channel, great info! I’ve been doing IF for a month now, and the benefits I experience is so profound that I don’t think I am ever going back. I did IF for the cognitive reason and I discovered IF pairs really well with low-carb diet. Personally, I like 18:6 quite a lot. And I do notice changes on the scale after day 10.

  • Thank you Dr. for the video. It’s is speaking in similarity with Dr. Fung and his approach. It is logical and hits on the root cause. I have also been reading on another school of thought, the Whole food plant based diet, and it has equal success stories from various groups of people. My head splitting question is which approach is more suitable? Is keto good for Long term especially for heart health?
    I am a T2 diabetic with oral meds with Metformin and glipzide. Please advice which more suitable for an individual depending on the case.

  • Whitney would you recommend an early dinnertime to ensure maximum overnight fasting time? If so, how early? Do you have any suggestions for how soon after waking to eat breakfast or a snack? Additionally, is there much research on whether a small evening snack (around 100 calories) interferes greatly with the benefits of intermittent fasting?

  • I have watched your video so far & my question to you sir what type of fat is good for diabetes & high triglycerides? Pls if you… thanks ����

  • If we have fibroid n uteral cysts. Can we do intermittent fasting coz I read intermittent fasting disturbs hormonal balance in women. Please reply sir

  • Imho I would encourage people with an eating disorder to at least try it. (With supervision)It could help reset things/hormones, etc and I would also get them to get checked to make sure they aren’t low on essential things like basic vitamins/minerals (like iron, vitamin D) and I would also encourage people to get off of any restrictions they currently follow (like low carb) also to reset certain essential hunger hormones and mood basically. I think the benefits (if it works) would outweigh any small side effects that they are already probably experiencing anyway from certain disorders

  • I loved his point on insulin medication. Many doctors are not open to this idea. He is true. No doctor say that cut the carbs I will reduce the insulin amount. He will say eat more times in a day in small amounts. Those people who are using insulin should take care coz of this diet, sugar levels will abruptly go down which may lose your consciousness.

  • Lee, any knowledge on a juice fast (eat sick and nearly dead film, google it) for fat loss? Is it possible and safe to juice fast and weight train to get lean?

  • eat what you want how you want if it makes you feel good. youre gonna die either way. best not to waste that limited life googling diets and typing every little thing into a phone app
