50 thoughts on “Time Restricted Eating Put to the Test

  1. Very interesting results. I work shifts though, mainly nightshifts, would the same positive results be gained following the same regime but sleeping during the daytime?

  2. Hi thanks for this update. Could you please inform us about the latest aspirin studies for cancer that have been taking place do you recommend taking also?

  3. So the best of both worlds is presumably restricting your calories to between the hours of 6 am and 10 am. That….sounds…..really fun….

  4. For 5 years I ate like that. Late feeding, 3h window. Felt great during the day but it took a toll on me during the evening. If you have an active lifestyle cramming that many calories into one meal is no joke. I sometimes even fell asleep, when I ate meals that were lean in fat but high in protein + carbs.

  5. So basically everyone is doing it wrong, as people who do intermittent fasting skip breakfast. But instead they should eat most calories as a breakfast. And it does make sense, as then you use them during the day. And all that fasted cardio etc has always sounded like a horrible idea. Eat well in the morning, and you have fuel to train.

  6. Go to bed without insulin floating around your bloodstream from recent food intake and you STOP its interference with Growth hormone, which gets neutralized by insulin… boom! more fat loss, more muscle gained with the same food/calories!

  7. can't wait for the next video! It's exactly what I'm looking for in my life! I've been vegan for years but still struggle to keep weight in line. Thank you so much 😭

  8. Dr. Jason Fung has been studying this subject for years and has a lot of great data too. I've been eating this way for about a year and have been able to lower my BS and maintain a stable weight. It's pretty simple, just don't eat after 7:00PM, get a good night's sleep, and don't have breakfast. Add a WFPB diet to the mix and you're batting 1000. Great info Dr. Greger…."as usual". Cheers!

  9. 5:18 Whats the problem? The 1 meal group has very good blood pressure, while the 3 meal group is starting to get too low blood pressure.

  10. I started eating one meal a day and I eat it around 2pm most days. After struggling with weight loss my weight is now finally going down and so is my body fat.
    I think I may increase to a 4 hour window because it can be hard getting all the calories I need in one hour.

  11. Can’t wait for the next part. It seems my beloved breakfast is safe for the time being.🥳
    Let’s find out when I have to stop eating 🧐

  12. Glad they finally did a study, this isn’t a new thing, it’s been a practice for my family since I can remember, fast from 6-7pm til 12 noon the next day, eat between 12 noon and 7pm…I have 4 women over 100, 3 over 80 in my immediate family all of them still moving around pretty good for their age.

  13. My interpretation of this is…

    Eat a big breakfast and small dinner: you have more energy in the morning and throughout the day, more likely to be more active throughout the day and excess calories are more easily burned off through said activities.

    Doing the opposite means you have a calorie deficit through the day, making you less active and making your energy churn lower. Then you get a big influx of calories before bed which causes your body to store excess as fat.

    Maybe I'm being naive here, but I'd bet the differing activity levels accounts for a large portion of the weight discrepancy between the two groups more than a nebulous concept like "circadian rhythm."

  14. I've tried many times to eat my food early & it's always a fail because the drive to eat at night after working all day is too strong..

  15. This matches the 3500 year old wisdom of the Charaka Samhita, the first written evidence of the Āyurvedic system of health. Eating this way also has side benefits of lowering inflammation and anxiety levels. A win-win.

  16. Shall I assume a single caloric beverage would be enough to screw up the rest period? I'd love to see that tested.

  17. so I don't entirely buy the conclusions here .. they are forced.

    wow .. ok Eating = Toxins In. Exercise = Toxins out. So 'Time restricted eating' .. is not a restriction at all ! .. eating all day is going to restrict the body in its ability to remove toxins far more.

    .. these people in this study are all over weight !! .. i.e. their body is not in a healthy balanced state to begin with !! .. they are ALL still over eating and no mention of exercise .. i.e. the studies are not demonstrating what you are assuming they are. The body is trying to get back into a healthy balance .. .. but it is being limited in the ways it can do that .. so the conclusions are skewed here… they are not conclusions about the effect of time restricted eating at all… this is what will happen when only 1 factor is changed when the body wants many factors changed .. its not that same thing as when time restricted eating is added to a person that is not in such a bad state of health to begin with.

    i.e. moving the bulk of food intake too close to bed time .. its a bad idea .. regardless of all other factors ! .. that is what is being shown here… the time restriction effect .. was NEVER tested here .. because all other factors were NOT equal as you are assuming. (i.e the peeps losing weight .. again .. is not necessarily a product of the effects of a smaller eating window)

    i.e. take healthy people .. that are already in balance and already adjusted to exercising a min of 30 minutes of hard puffing a day .. have been intermittent fasting for 3 months or more already, people that know what to eat .. and don't eat for emotional/addictive needs etc .. then these studies will show that it does not matter when you eat as long as its not 3 hours before sleep… and yes the time restricted eating is vital to health .. however to long-term health ! The digestive system is a massively complex machine .. and when its on .. its just like your body is walking in terms of calories being consumed .. but without the movement to shed the toxins from those calories. i.e. the body can't take toxins in and get rid of them at the same time… it just can't do that !

    Time restricted eating = proper time for toxin processing and release.
    Time restricted eating = a restriction in toxin build up.
    Time restricted eating = long term health benefits mostly .. i.e. hard to prove in a study

    I'd suggest measuring the length of sleep .. or recovery time from hard exercise .. then you are testing what time restricted eating actually does for the body .. these studies are NOT doing that at all .. they are off target .. as if they don't understand what they are meant to be measuring and why

    So eating too early in the morning .. while restricting the eating window down to 4 hours per day .. may not be the best idea .. the body is trying to get rid of toxins in the morning that it accumulated in the night .. however .. no study is ever going to show this dynamic .. studies can't do that.

    I start eating around 3-4pm .. my body has never liked eating in the morning .. it does not feel right to wake up and start eating .. and its not practical to take 2 hours out of the middle of the day to eat .. so… 3-4pm it is. (ideally)

    however I look forward to the next vid here on .. restricted eating .. in the morning. .. I hope its not basing any conclusions on weight lose or weight gain tho ! gees !

  18. Finally the all awaited actual intermittent fasting video! When I do IF I always eat early and skip supper because it fits my schedule better, and so far it’s looking like that’s actually the best thing to do here haha. Looking forward to the next part!

  19. What if you sleep 9am-5pm & work 11pm-7am, eating a single meal (all the day’s calories) at 6-7pm each day? Could sleeping during the day etc. cause differing results?

  20. Excellent…I’m keen to see next video…I eat in window between noon and 4 or 5…perhaps I should switch it up?

  21. Another fat people how to lose weight video! How many of these do we have to suffer through. Hey Doc not all of your subscribers are fat and dumb.

  22. Thank you Sir for this video all these kinds of questions pops in my head as I fast for 18 to 20 hrs and eat in a 4 to 6 hr window. So early wanted to know the benefits. Can't wait for the next video.

  23. If you missed the last video of the day, it’s the exciting announcement that How Not to Diet is hitting shelves on December 10. Check out the book trailer (https://nutritionfacts.org/video/trailer-for-how-not-to-diet-dr-gregers-guide-to-weight-loss), and you can still pre-order the book to get it right when it comes out: https://nutritionfacts.org/how-not-to-diet/. -NF Team

  24. So for us scrawny people trying to gain weight…eat every 3 hours? I'm currently eating 700kcal at 6am, 9am, noon, 4pm, and 7pm but it's really hard. After the first meal I'm nauseous all day.

  25. Interesting.
    For now, I'm doing well on WFPB, eating whenever I want until I feel satisfied, and have lost just under 4 stone. But I am obese. As I get nearer to my goal weight, however, I'm guessing I may have to reconsider.

  26. WOW he finally agreed with mainstream nutrition themes flowing around on the internet. Now all he has to say is have a big breakfast with eggs and meat and 3 hours later eat some veggies and whatever calorie source you want… and that's it. You will live to 100.

  27. Fantastic summary of TRF! Took me months to research this before. Now it takes just 6 minutes. This is worth it's weight in gold….

  28. How would this work for people that work nights? I go to work around 4-5pm and finish around 2-4am, would the best time be to eat just before work? I always ate after work because I really don't enjoy going to work with a belly full of food
