Since retiring we moved our main meal to noonish. For me that is my first meal of the day. Our lighter evening meal is around 4:30/5pm typically. Since eliminating sugary and starchy foods, I’m having no difficulty maintaining this eating window without snacking. Increasing protein at mealtime along with drinking more water has reduced hunger tremendously. 😊

[@zerocarbdoc]

A lot of respect for Dr. Panda!

I practice time restricted eating and very low carb (almost carnivore) My weight is gradually coming off, but most important - I feel TERRIFIC ! I'm 67, but zero aches and pains, and lots of energy.

[@mariahcantu7668]

Congratulations! Greatest news! Hope you are still doing amazing!

[@RogueCylon]

It’s a journey. I used to weigh myself on diets all the time to track progress. But learned to listen to my body more. We slowly gain weight when eating poorly. So losing weight slowly is a nice indicator of eating better. It’s also better for the body rather than rapid weight loss.

Time restricted eating plus low carb has been how I have regained my health. Now I am practicing a 3 - 6 hour eating window depending on the day and I try to exercise before my eating window. Works for me 👍🏻 I love this channel. Thanks for all your great content. You are helping to change lives 🌹

[@pvl256]

It's interesting - I've found myself focusing on the "time not eating" window - so I'm conscious of when I last ate the day before, and then set my "earliest time to eat" the following day based on that. This way feels more flexible to me.

[@biggreenbananas8929]

@@pvl256 That's what I do too. I make sure I do not eat for at least 16 hrs in a 24-hr cycle. That means if my last food was at 4 PM, my next food would be after 8 AM the next morning. But usually I eat around 10 AM. I have kept my weight in check with BMI to 21 since.

i have been sleeping 4-5 hours for 29 years now since i read that the body only needs 3 hours of deep sleep to rejuvenate and also learned that yogis can do well with 4 hours of sleep. i immediately fall asleep when i go to bed. wake up with out alarm clock within 4-5 hours. i am 69 years old, no gym, no diet restrictions and have no chronic illness. i have the flexibility and energy of a 20 year old. my husband and are experimenting on having only one meal a day (noon time) and coffee (i have tea every now and then) and some nuts or a cookie at 4pm. i think that even ups my energy and clarity of mind. dr. panda, can you do a study along this area of sleep? i believe if we do not carry our mental baggage or still undigested food or too much stimulation to bed, we will do well with less sleep. there is so much in life than to stay too long out of it every day.

[@jezzab01]

Brilliant. Possibly my favourite podcast so far. Life changing.

[@elephantcup]

Gold. So much good content here, I need to watch it again and take notes. I've been on time & calorie restricted/ low carb for almost a year, every benefit that he described, I've experienced. I attribute the elevated mood (sometimes euphoric) in the AM to ketosis. My mood and energy usually build until I eat at around 2PM, then they sag. Mind and body happier with no food.

[@maxmohanmedia98]

What a brilliant man. And kind man!

[@bressonNemesis]

I respect and comment Dr. Panda's work. When did his lab begin discovery and publishing of their findings? Even as early as the early 90s if not earlier, it was well understood that food eaten later at night tend to store as fat. Further, there were plenty of anecdotal evidence around eating earier as a weight loss strategy.

[@krishnagiridhar3692]

Learnt importance of keeping eating window fixed for good health not have erratic eating habits. I am motivated to start fixing rating window 12 hrs and see how much discipline is needed and then move from there. Thank you so much for creating this awareness

[@kguruprasanna7768]

A brilliant program. In Indian culture many festivities are linked with "fasting". Following circadian rhythm morning till night with simple and small meals should help surely. Along with, a happy mind is important as well. Let us enjoy fasting.

[@dmmcmah1]

Time restricted eating works. I was headed towards diabetes and obesity but put the breaks on eating keto. But it wasn’t really until I added time restricted eating that it really kicked in. Weight loss is automatic. I started going 16 hours and struggled with hunger at first, but now I go 18-20 hours fasting every day with no effort. I am a night owl so wait until 3-4 PM for my first meal, and that way I can have normal social dinners, and still eat hours before I go to sleep. I will say it seems like I sleep a much deeper sleep as well, and sleep apnea cured.

[@PatBoyd59]

[@parmodbudhiraja7604]

Thanks very much Dr. Panda for your wonderful work on intermittent fasting. I observe daily almost 8 hours eating window without any difficulty at all. I am aware that pancreas works well from 08AM to 8 PM and adjust my 8 hours eating window within the period between 10.00 AM to 0700 PM. If earthing daily at least 2 hours ( meaning in direct contact with the earth ) is added to intermittent fasting, it gives more better results. The electrons from earth which flow in our body neutralize the positive free radicals in the body reducing inflammation leading to various diseases within our body.

I listened to him on Huberman's podcast and immediately switched to his way of fasting. Absolutely nothing except water after 6.30 pm and broke my fast at 8.30 am, within 3 weeks, my sleep pattern got better and stomach and lower back fat started reducing. I did for one month and due to some reason stopped but I am planning to do it again from next month.

[@donnabronner4837]

This interview is outstanding!

[@dreamingrightnow1174]

This discovery, when we eat is fascinating and something I'm learning about my own eating patterns as I restrict my feeding period. And I suspect that people who are willing/able to participate in the process, as simple as it is, is still selecting for more "conscious" eaters; less compulsive. It's a guess on my part as a highly compulsive eater who still hasn't recorded my own eating patterns. If this is the case, then many of feed over a wider window than 15 hours; perhaps as much as 20. This is discussion is motivating me to stick with my window, in understanding why it's so difficult at times.

And a little bit about the visits to the dentists,. As a chemist, I used surfactants, to reduce the surface tension, in the water based coatings. Our toothpastes have some. But, we do not use them correctly. Instead of spitting the foam, we should try to rinse our mouth with it, by diluting it a little more, in order to remove food stuck in the crevices. That should keep the bacterias away.

I’m doing IF and I lost 10 lbs. I’m at my perfect weight for over 1 year , keto diet. Very little fiber. I Rejuvenated with 10 years in one year. I also walk, do yoga and swim. I stopped fiber because being vegetarian for 10 years made me bloated and I was diagnosed with H Pilory and SIBO. Once cured, my stomach flattened like when I was a teen! ( I kept the same weight as before: my perfect weight). IF plus keto did it for me. 4-6 hours feeding window. I can’t even THINK of eating after 4 pm. My body completely shifted and feels very light and comfy !! If I eat later, I’m very uncomfortable and sleeping is very light.

[@sleepsmartsmashstress740]

WHERE TO TIME THE EATING WINDOW (other than in fast food outlet drive in ) The plugging of the food consumption 8-hour window gets thrown around but the answer would not come from academic research on it. The most logical position to take is to rhyme it with your sleep cycle and try to plug the food intake 8 hours exactly opposite to the 8 sleeping hours by inserting 4 hours before and 4 hours after the food intake window. It would be impossible to argue with this intuitively arrived at posture that I am personally practicing but may be 3 hours before breakfast and 5 hours after the last meal (a snack)

Odd that Panda didn't make his usual point that the body processes glucose better in the morning than the evening. Other videos I've seen where he mentions this have caused me to set my eating window from 9 am to 3 or 4 pm, with most the carbohydrates being consumed in the morning.

I eat one meal per day at 5:00 pm. I sleep well, have plenty of energy, never feel hungry or crave snacks and I've lost over 30 kilos in 18 months. Don't look too deep into it because we were skinny and fit 40 thousand years ago and we didn't have all this mixed research or mice to test on.

[@r.p.8906]

I would argue that in AM our stomach acidity is the highest and the proteins are digested much more effectively. The acidity of the stomach is also key in destroying all bacteria ( H Pilory being one that could lead to cancer). A carbohydrate breakfast will decrease acidity ( increase the ph) and later in the day, at the second meal, the proteins will be digested and absorbed less efficiently. Bacterias might survive.., I try eating my fat and protein in the morning..,

[@surendranerurkar1138]
