What if eating two cups of blueberries a day could prevent cancer? If drinking a kale-infused smoothie could counteract missing an hour's worth of sleep

I won this book in a Goodreads giveaway.

If you have a brain then you already know everything in this book.

Red Meat=Evil
Fried Food = Evil

We all know this but....

God! How boring is it to eat healthy every single day of your life. And that is what this book says to do.

No cheat days


Imagine never having chocolate cake again or eating fried chicken.

Sure I could live to be 100 only eating Steamed Chicken Breast & Broccoli and only drinking water but would I want to?

I read an ARC of this book. This is a very readable book with good information and some humor to keep it from being overly dry. I enjoyed the variety of situations each chapter focused on. Not a book to be read cover to cover but still can get the information from reading most of the chapters.

If you read healthy eating books regularly, you are not going to read much here you haven't read elsewhere. But I'm trying to get geared up to lose 10-20 pounds, and when I received an advance reader copy of this book I took it as a sign.
This book is very easy to read, and it is broken into chapters you can pick and choose between (what to eat when you need to shrink your prostate - nope; what to eat when you are nursing - nope; what to eat when you don't want to lose your mind - yep!). Somet

If you wanna learn more about how food works and how you can apply that to your daily eating habits, this book gives you insights into what are the best food options and what works best in different situations (like when you're stressed, you can't sleep, you're sick, etc.) This book talks about the main nutrients, best food options and also talks about the best time to eat!

Here is a summary of my main highlights and takeaways from the book:

The last self-help eating book I read was Fit for Life back in 1989. (Seriously.) I loved that book (which as I recall) was full of recipes, some pretty good ones at that. It got me on a juicing trend.

I have no idea where that book is today.

It's time to change up and really think about what we eat and how we eat it; hence I picked up What to Eat When.

Although this book is recipe free, it does have some great tips on getting the most out of food, like vegetable preparation and freezing. I appre

Again. I did *not* finish this book. I got to page 70.

I cringed when I saw it was written by Dr Oz’s affiliates. I don’t think he’s evil, but a psuedoScientist that encourages people to buy unnecessary expensive items in the name of health. A modern age Snakeoil salesman.

They try to sell that you should only eat during sunlight hours bc of circadian rhythm...something we don’t quite have a full understanding of yet, but notice that our bodies do certain processes at certain times automatically

My take away from this book is:
The food we consume has an impact on our health:
1. Food is medicine. "The single most important decision you make every day is what you chose to put into your mouth."
2. Timing matters. Eat during daylight hours only. Eat most of your calories in first half of your day. No night eating. Grab crunchy raw veggies if it’s emergency. Fast every night for 12-16 hours.
Make wise food choices. Be prepared with substitutions when you crave foods that are not healthy. Avoid

I read about the book in Nat Geo (it was evidently written in conjunction with a Nat Geo team), and picked it up.

It is a very easy read, with most of the "when" part near the beginning. The authors espouse:
-Restrict your eating time to 12 hours during daylight
-Breakfast and lunch are the most important meals - you want to front load your calories
-Our peak hunger occurs at night (8pm ish) but the body is actually primed to interact best with food in the morning
-Aim to get 3/4 of your calories in

I was sceptical about the idea that eating certain foods at certain times would be good or bad for you, but the way it's presented in this book is quite convincing and I am considering putting the it to the test. I did feel that the book was unnecessarily padded out and that the main message could have been condensed down to a shorter book, but I appreciate publishers like a 300 page book so I understand why that was. ...more

A quick read with an interesting premise to only eat during daylight hours. The idea of eating 3/4 (or more!) of your daily calories before dinnertime would take a bigger lifestyle change for most people... but I like the reminder of how beneficial eating whole foods is, as well as the sections in the last half of the book that talk about the health benefits of specific foods.

January is the month when people make their resolutions, and many people choose to get healthier as their top one. Dr. Michael F. Roizen and Dr. Michael Crupain (both of who have worked with Dr. Oz) have a new book What to Eat When to help achieve that goal.

What to Eat When gives the reader a 31-day plan to work on, as many other diet books do. What makes this book unique is that is also has chapters that deal with eating in specific situations- what to eat when you are stressed, experiencing gr

The authors consider their book "life changing" with "amazing information," but I didn't see this. While they did have a few interesting tips, including making dinner your smallest meal of the day, eat less calories than you're burning, and don't eat after sundown, their advice was not always practical, i.e. the sundown thing. It's like they think everyone works 8-4 or 9-5 and goes straight home after work.

Many of their tips I had seen before or learned via WW (aka Weight Watchers): Drink a ton

I saw this book on the "new books" shelf and it seemed like a worthy choice to start 2019 off on the right foot. I liked that it was written by (2) doctors and although I loved the way the book was organized, much of the information was not new to me.

In this book you will learn how to use various foods to increase your longevity and improve the way you feel. The authors claim that out bodies are designed to eat more in the morning and less in the evening for optimal effectiveness. They recommend

The book has an interesting premise, when is just as important as what you eat. Timing meals so you eat your heaviest meals in the morning and lighter meals in the evening. Although with this, the book asks for a paradigm shift of eating. Rethinking what foods you eat for breakfast and what foods to eat for lunch and supper. For instance, one of the recommendations was to cut supper in half and eat the other half for breakfast. For the average person this can be an appauling thought. They also s ...more

I was lucky enough to receive a copy of this book in exchange for a fair review, and I have to say that I went in very skeptical and came out very pleased!
What to Eat When is not a fad diet book, it’s a book designed to help you learn better eating habits and make real lasting changes in your life!
This is not the type of book you want to sit down and read cover to cover, and I found it most useful and most enjoyable to pick chapters from the table of contents to peruse at my interest. For examp

"When to eat when" is a book about how what you eat is as important as when you eat it.
Once that point is a made, the book presents a nice guide on how to eat food who loves you back. Food who doesn't punish you for eating it, but rather helps your body and your mind to be an ally in your journey.
In that guide you can find examples of things to eat in diverse life situations: when you're grieving, before a job interview, when you have diarrhea, when you're trying to conceive, ...

With so many books out there telling us what the new fad diet is sometimes it’s hard to decide what’s best. One day eggs are good, the next day eggs are a big no no. Want a glass of milk? Good luck with that! 2%, soy, cashew, almond, coconut, oat, hemp, rice I could go on and on!
What to Eat When is not only a guide to foods your body needs, but also a guide to why it needs them. Delicious recipes with gorgeous pictures with have your mouth watering!

This is a good book, but it wasn't really the right time to read it (during a pandemic where I shouldn't be going to the grocery store a lot to change my eating habits). It did give me some things to think about and had a good plan to slowly change to a healthier style of eating. I appreciate that the authors don't advocate any extreme measures and instead are recommending healthy foods and arranging your eating so that you get the most out of that food. The back two-thirds of the book focus on ...more

This book is very easy to read. It sums up basic information that is probably familiar to anyone who follows health research. The chapters are organized so that topics of particular interest can be chosen from the Table of Contents. By reading the entire book it becomes obvious that certain foods are best to consume for good nutrition, and others should be avoided.

The main emphasis that could be new to some readers is that meals should be consumed during daylight hours, and food intake should be

I was really excited when I saw this book in a store one day but as soon as I started reading it, the excitement wore off. For the most part, what the books authors want you to do is eat while the sun is up and make dinner a smaller meal. I like the idea of this but for someone who usually works from 6:30-6:30, I can’t have eat every meal while the sun is out.

There is nothing new in this book. Eat lots of fresh fruits and vegetables, healthy fats, some carbs and some meat. Limit red meats, alcohol, refined sugar, unhealthy fats, processed foods...everything you love basically...Eat your biggest meal in the morning, followed by a big lunch and a tiny dinner. Try to only eat during daylight hours. Drink your weight in water.

I thought this book would be more about 'eat blueberries with lemon for colon health' or consume 'Garlic+salt water to cure a sore

Helpful and informative. I am a health foodie and all the “what” diet advice is already part of my life. The “when” was very helpful and I began to follow it immediately. I struggle slowing down and find that setting the fork down helps. Also the eat prior to 2pm fits right into my hunger window and adding the calories for a snack in the initial days’ calculation as opposed to reaching into the jar when no one is looking. So, thank you for this book. There is something in these pages for all of ...more

I read this directly after reading change your schedule change you life by Dr. Kshirsagar and I liked that book much better. The second half of this book was.. what to eat when ... you have a test.. or a bad day.. or a hangnail (okay maybe not that one) but blah blah blah and 80% of the advise for each was all the same. I'm not saying that there was no point to reading this book but I learned much less from it than I had hoped. ...more

Shelves: nutrition
This book is very repetitive and not nearly as specific as the cover art implies. For people that already eat healthy there might be a couple of pointers to learn but for the most part it is geared towards making changes for people who regularly eat junk. Additionally, as far as lifestyle changes go, this plan is a bit extreme. Most people will not willingly give up all sugar, eggs, dairy and meat for the rest of their lives. If they were we would all be vegans already.

Do not recommend. Reeked of standard diet book writing style. Lots of really dumbed down analogies instead of real information. The basic concept (thinking about the timing of your eating, for example eating more earlier in the day) seemed somewhat similar to real advice I'm getting from a nutritionist, so it's not complete garbage, but I didn't find it very educational or helpful overall. I only finished it because it fits in a "reading bingo" challenge category so I wanted credit for it. ...more

Fascinating study of the what and when of eating. It turns out our bodies use food, of course the right food, most efficiently depending on the time of day we eat. There are numerous mentions of the right/best foods: more fruits and vegetables, nuts, seeds, olive oil, salmon, whole grains, complex carbs, lots of water. The "when" is truly interesting as our bodies do best when we eat according to our circadian rhythms. We are more basic than we ever realized. ...more
