“what is the time when your body's system is expecting it to eat because it's kind of averages Southeast kind of thinking okay maybe for you if you're eating breakfast at say somewhere between 6 AM 7 30 7 45 I eat it maybe you are expecting food around seven o'clock let's forget about 6 15 that's an outlier and then similarly at the end of the day if somebody is eating finishing the last bite or the night Gap whatever you call it say one day at 9 pm 9 30 p.m 10 11 12 30 or 1. Let's ignore that 1 and 12 30 but still we got somewhere between seven to eleven thirty for that person over three weeks time”
Main Takeaways:
- The body's system expects food based on average eating times.
- Breakfast typically expected around 7 AM if eating occurs between 6 AM and 7:45 AM.

“most sleep researchers agree that children and teenagers should sleep somewhere between 9 to 10 or 11 hours because young children even five to ten year old they should sleep nine to ten hours they're just pumping out growth hormone and growing growing and then the teenagers actually the recommendation is and they should be sleeping nine hours because if you take teenagers take out all the stimulatory inputs to them and then remove homework assignment and everything and then let them kind of equilibriate to their homeostasis what are likely how many hours they're likely to sleep that turns out to be somewhere between eight and a half to nine and a half hours”
Main Takeaways:
- Children and teenagers have specific sleep needs for healthy development.
- Young children (5-10 years) should sleep 9-10 hours to support growth hormone production.
- Teenagers should ideally sleep 8.5-9.5 hours to reach a natural state of rest.

“Circadian aspect come in because if you're moving that breakfast time or dinner time three four hours essentially causing maybe a metabolic jet lag you know in short term in weeks months or maybe even few years you may not see any change at the same time we don't know what is the long term consequences.”
Main Takeaways:
- Shifting meal times significantly can cause 'metabolic jet lag'.
- Short-term effects might not be noticeable, but long-term consequences are uncertain.
- Consistency in meal timing may be important for metabolic health.

“whether the depression anxiety the mental health aspect will benefit from fasting because now as there is more and more evidence that there's this gut brain axis and whether the presence of food or the microbiome changes in the gut if they can affect brain then maybe long-term fasting periodic fasting a few days of low calorie diet back to back will be interesting to see how it impacts brain health.”
Main Takeaways:
- Exploring the potential benefits of fasting on mental health due to the gut-brain axis.

“so it took mice and then measured their blood glucose at different time of the day and in fact just like human blood Lookers our blood glucose fluctuates a little bit uh she saw that rhythm and then in every two hours or three hours on different days of course so you have the same dose of Metformin to mice and what she found was a different time of the day metformin had very dramatic change in glucose reducing ability”
Main Takeaways:
- Metformin's effectiveness in reducing blood glucose levels varies depending on the time of day it is administered.
- Blood glucose levels naturally fluctuate throughout the day, which affects the drug's performance.
