Summary
Change your daily routine， transform your health。
Circadian rhythms are biological processes or clocks that exist in each one of our cells。 Programmed to turn genes on or off at different times of the day or night， they influence every aspect of our health from weight and energy levels through to resistance to disease and infection， and how well we sleep。
Now， in The Circadian Code， this new science is revealed， showing that the timings of our day （when we eat， sleep， exercise， work） are more crucial than we ever thought before。 And that， most importantly， if your daily schedule is out of sync with your circadian rhythms， you can fix it！
Whether you are a shift worker， a frustrated dieter， someone suffering from sleep problems or chronic illness， whatever your health concern， The Circadian Code is the key to unlocking your health。

After hearing a fascinating interview with Dr Panda on the radio， I was disappointed when the book arrived looking like a tawdry self-help weight loss manual， and to some extent it was written in a similar tone。 Regardless， I found it to be very informative。 While wanting to better understand the science of sleep， the author explained a number of interdependent processes。 His recommendations are based on evidence derived from quantitative research studies which were well described。An interesting After hearing a fascinating interview with Dr Panda on the radio， I was disappointed when the book arrived looking like a tawdry self-help weight loss manual， and to some extent it was written in a similar tone。 Regardless， I found it to be very informative。 While wanting to better understand the science of sleep， the author explained a number of interdependent processes。 His recommendations are based on evidence derived from quantitative research studies which were well described。An interesting， quick read。 。。。more

Listened to this book。 I find informative books often better this way。 Loved his ideals & principles。 Very knowledgeable using a scientific， yet simple plan。 My wife and I are now implementing his recommendations。 They seem well founded。

I love this book！ I think everyone should read this。 It covers our circadian rhythm， why we need to follow it， how to follow it and what happens when we don't follow it。 My lifestyle is pretty in sync with the circadian rhythm but I still picked up new things that I can apply to my life or adjust。This is a 9 hours audio book。 It has lots of great information in。 I'm listening to it again in case I missed anything。 The only thing I did not like is the narrator。 He pulls the last word of every sin I love this book！ I think everyone should read this。 It covers our circadian rhythm， why we need to follow it， how to follow it and what happens when we don't follow it。 My lifestyle is pretty in sync with the circadian rhythm but I still picked up new things that I can apply to my life or adjust。This is a 9 hours audio book。 It has lots of great information in。 I'm listening to it again in case I missed anything。 The only thing I did not like is the narrator。 He pulls the last word of every single sentence and it gets annoying。 。。。more

This is such an amazing book！ I have improved my health so much by just restricting my eating window to eleven hours。 I have more energy， my pulse rate has gone down， so have the chronic inflammation in my body， my taste has improved， my smell has improved。 My biggest challenge now is to get enough sun light。

Very clearly written and easy to see how consistent daily rhythms affect our overall health。 I'm following his advice on time restrictive eating （TRE）， access to light， exercise and sleep。 Within days， my sleep is already deeper and there is less waking （and staying awake）。 I've also stopped eating after dinner， which was a habit I was trying to quit anyway。 Very clearly written and easy to see how consistent daily rhythms affect our overall health。 I'm following his advice on time restrictive eating （TRE）， access to light， exercise and sleep。 Within days， my sleep is already deeper and there is less waking （and staying awake）。 I've also stopped eating after dinner， which was a habit I was trying to quit anyway。 。。。more

This book itself does not deserve 5 stars -- it’s repetitive and there is probably some exaggeration and （as my non-doctor-self is assuming） some implications that aren't quite right。 However the *basic concept* deserves all the accolades and could solve a lot of problems for our entire population。 But instead of being a 200 page book I wish this was a 10 page pamphlet and a thorough part of medical school training。The ideas presented are simple and - assuming they work for even half the people This book itself does not deserve 5 stars -- it’s repetitive and there is probably some exaggeration and （as my non-doctor-self is assuming） some implications that aren't quite right。 However the *basic concept* deserves all the accolades and could solve a lot of problems for our entire population。 But instead of being a 200 page book I wish this was a 10 page pamphlet and a thorough part of medical school training。The ideas presented are simple and - assuming they work for even half the people who are struggling with a litany of medical issues - worthwhile。 The basic premise is more about overall good health than weight loss: All of us， and all of the cells in our bodies work on a circadian code。 There are times of every day that our brains， guts， livers， hearts， etc work at peak performance。 And of course， times that these organs need to rest。 That rest is the key to making sure that everything is in good working order- and it's rest that most of us （and our organs） don't get enough of。 By consuming calories 13-15+ hours a day， we're not giving our bodies a chance to （to put it in non-medical terms） recover and recharge。 But there's an easy fix: If we only eat in a 12 hour a window every day （say， 7:30a-7:30p） AND get a consistent amount of sleep every night （not less than 7 hours for most adults， not less than 9 for most kids） then it will reduce （or as Dr Panda believes; REMOVE） the need for a ton of the medications that we- as a society - rely on。 [If we want/need to lose weight or truly fix some health problems， only eat in a 8 or 10 hour window。] If this plan can alleviate even a fraction of the suffering in our country （and the world） due to chronic health problems/side effects of medications/cost of health care/mental health struggles etc etc， then it sure is worth it to give this free solution a try for a few weeks， at least。 The question is， how do you get everyone on board？ I have no idea。 The book isn't engaging or concise enough to be a best-seller （it came out three years ago， anyway） but reading it and recommending it to others is at least a small step in the right direction。 So check it out and share it。 It's easy （and cheap） enough to give it a try， and the results could change your life。 。。。more

This book is a mixed bag。 Dr。 Panda opened my eyes to the circadian rhythm affecting our diets。 But， he also offers such terrible advice on diet that I'm wondering if the food lobby backed his research。 Further， like many books by specialists， the short book suffers from bloat。 I'll cover each of my takeaways in the following paragraphs but can't rate above 2-stars。 Circadian rhythm is important。 Dr。 Panda has dedicated his career to studying it and provides the most in-depth review I've read of This book is a mixed bag。 Dr。 Panda opened my eyes to the circadian rhythm affecting our diets。 But， he also offers such terrible advice on diet that I'm wondering if the food lobby backed his research。 Further， like many books by specialists， the short book suffers from bloat。 I'll cover each of my takeaways in the following paragraphs but can't rate above 2-stars。 Circadian rhythm is important。 Dr。 Panda has dedicated his career to studying it and provides the most in-depth review I've read of the subject。 The book explains that different cells within each organ follow their own rhythm。 The prose is easy to read and written for a layman like myself。 Key takeaways: 1。 time-restricted eating， defined as eating in an 8-12hr window each day， is optimal for health。2。 start eating in the morning within an hour of waking up and finish between 2-4hrs of sleeping2。 wakeup with sunrise （optimum） and get 7-8hrs of sleepThe takeaways are easy to understand and make sense。 I imagine our hunter-gathering ancestors operated similarly。 There's more analysis and takeaways but I believe these are the cornerstones of Dr。 Panda's research。 All good so far。 However， Dr。 Panda falls into the whirlpool affecting many specialists' works。 He believes that following your circadian rhythm will solve all problems。 He goes as far as to say， "everyone should focus more on when they eat， instead of what they eat。" He also cites studies indicating TRE is more important than diet in mice。 But， he qualifies his statement with a short blurb on what to eat （which is quite good）。 By offering advice on eating in such a manner， he adds to the confusion surrounding diet， nutrition， and exercise。 Frankly， I skimmed the entire third section where Dr。 Panda ties circadian rhythm to every disease known to man。 According to the good doctor， ADHD， diabetes， cancer， and more can be prevented and treated by following your circadian rhythm。 He gives short examples after each strong statement from his private practice。 Pardon my skepticism， but I can't imagine eating an American diet and following your rhythm will cure all ills。 Hence why I skimmed the section。 It reads like a specialist - pull out all the studies linking your specialty to positive outcomes and overwhelm the reader with data。 Then， they'll believe you。To conclude， circadian rhythm is an important topic and I learned plenty from reading Dr。 Panda's book。 But he offers a lot of conflicting information and offers his discipline as a panacea to all health problems。 And I can't stand for a book that illustrates the world in such black and white。 。。。more
