Editorial Reviews


From Dr. Theodoros Kelesidis, Harvard Medical School & Department of Medicine, UCLA School of Medicine
I am often asked when there will be a proven prescription for weight loss. The Smarter Science of Slim is that prescription.

Jonathan Bailor's easy-to-understand and engaging style disguises an astonishing amount of otherwise incredibly complex scientific information. You will not realize you are learning so much because you will be so involved in what you are reading. The pages you are holding will change the way you feel and look faster than any pill ever could. It is incredibly rare to find anything as thoroughly researched and carefully analyzed yet so clearly and engagingly presented in the context of everyday living and eating. For anyone who has struggled with managing weight or maintaining energy, you do not need pills. You need this book.

From Dr. JoAnn E. Manson, Chief, Division of Preventive Medicine, Brigham and Women's Hospital, Professor of Medicine, Harvard Medical School
Jonathan Bailor has performed an invaluable service with his book, The Smarter Science of Slim. Jonathan has studied thousands and thousands of pages of academic research on health and weight-loss, and he has put the results into terms that the everyday person can understand. Jonathan's work is far from just another diet book.

The Smarter Science of Slim dismantles the myths that have contributed enormously to the health and weight problems that many people have, and replaces them with easy-to-understand facts that will change the way you think about eating and exercise.

The scientific community now knows a great deal about how the human body works. In culling the literature and gathering the results of so many clinical studies, Jonathan Bailor presents a weight-loss program that is based on rigorous science. As a treasure trove of reliable information and sound facts, The Smarter Science of Slim can help you take charge of your destiny and turn the tide on weight gain.

From John Little, Author of Max Contraction Training, Co-Author of Body By Science
As someone who takes fitness and health seriously and has written extensively on this topic over some 30 years, I am generally underwhelmed whenever I see a new how to book enter the marketplace. Most are celebrity driven, and most celebrities simply do what their personal trainers tell them to do with little regard for physiologic fact. I am pleased to say that The Smarter Science of Slim represents something different. Strikingly different in fact.

Author Jonathan Bailor has that rare gift of being able to take highly technical scientific data and interpret it in a way that the average person can understand instantly. In addition, he is able to do so in a manner that makes entertaining and compelling reading while clearly indicating how (and why) the last 40 years of fitness and nutrition advice have made us fatter and more at risk for disease than at any other point in our species' history. But most importantly, he is able to take that mountain of scientific data and divine the practical and simple direction it is pointing to in terms of advancing human health and fitness. The book you are holding in your hands can be said to represent the thinking person's guide to exercise and diet in the 21st Century. No fads. No gimmicks. No celebrity-driven pitching of nonsense. Finally, a book that is worth reading; not only for the sheer pleasure of it, but also for its ability to dramatically and positively change your health, strength and life.


From Dr. Larry Dossey, Oprah medical expert, New York Times best-selling author, and Former Chief of Staff of Medical City Dallas Hospital
In The Smarter Science of Slim, Bailor demolishes the dietary and nutritional nonsense that has contributed to the epidemics of obesity and diabetes in our country. In its place he erects a simple program anyone can follow that is based on solid science and common sense. The Smarter Science of Slim is likely to be the last diet book you will ever need to buy. Unless you enjoy failed diets, do the right thing the healthy thing and read this book.

From Dr. John J. Ratey, Harvard Medical School, author of Spark: The Revolutionary New Science of Exercise and the Brain
The Smarter Science of Slim reveals some of the latest and best scientific research on the real story of diet, exercise, and their effects on us. Bailor s concept of high-quality exercise is rapidly gaining support in the medical community, and has repeatedly delivered clinical results which seem almost too good to be true. I heartily recommend this book to people who want to take responsibility for their own health.

From Dr. Anthony Accurso, Johns Hopkins
The Smarter Science of Slim sheds light on the surprising discrepancy between the way healthy nutrition has been presented to the public and the science that underlies it. The idea that fat in the diet translates into fat on the body has dominated nutritional discussions for decades. This work challenges this central idea, and offers clues about why diabetes has been on the rise, and why so many people who are intent on losing weight have found it so difficult to do so. It is an important piece of work.

From Dr. Jan Friden, University of Gothenburg
Revolutionary. Thoroughly researched, rigorously simplified, and downright fun, Bailor's work stands head-and-shoulders above the mass of fat loss myths lining bookstore shelves. In his surprising and scientifically sound expose of the modern fat loss mythology, Bailor reveals the sources of our fat loss struggles and provides straight-forward, practical solutions. Everyone, and I mean everyone, will learn and laugh a lot while reading The Smarter Science of Slim.

From Joel Harper, Oprah and Dr. Oz Show fitness expert
When it comes to the most important part of your life, your health, Bailor has written a book that is a must-read for knowing the truth about evaporating body fat. I am a firm believer in achieving the body you have always dreamed of, and Bailor opens the black box of fat loss and makes it simple for you to explore the facts. Read this book today in order to live your best life.

From Dr. Fred Pescatore, Author of The Hamptons Diet
WOW! This book will blow your mind and is a must-read for anyone who wants to learn how to be healthy the 21st century way. In The Smarter Science of Slim, Bailor exposes the dietary myths of why we as a nation are still overweight despite years of best-selling diet books. Calories, fat, exercise and hormones - it is all in this book and finally someone got it right. The diabesity epidemic stops here. Poignant, applicable and easy to read, Bailor's relevant work couldn't have come at a better time.


From Dr. Wayne Westcott, Quincy College Fitness Research Director and author of Get Stronger, Feel Younger
In The Smarter Science of Slim, Bailor entertains as much as he educates. Simplifying and integrating an amazing amount of important scientific and clinical research, Bailor presents a well-conceived, well-researched and well-written book, in addition to a very sensible, practical, and successful approach to losing fat.

From Cynthia Pasquella, Board Certified Clinical Nutritionist, CHLC, CWC
The Smarter Science of Slim is the go-to source for all that is practical, realistic, and effective when it comes to weight loss. Bailor brilliantly brings together all the outdated myths (i.e. eat less, exercise more) and dispels them one at a time in a fun, easy to understand way. This book changes the future of permanent weight loss forever!

From Dr. William Dunn, specializing in the obesity/cancer link
Fat loss theories are everywhere; except here. The Smarter Science of Slim is the source for the fat loss facts. Bailor has taken a lot of amazingly complex medical research and turned it into a simple, clinically proven fat loss program that will change the way we think about fat loss.

From Dr. William Davis, Fellowship of the American College of Cardiology, author of Wheat Belly
Brilliant. The Smarter Science of Slim is a masterful compilation of nutritional and exercise science disproving the archaic fat loss theory of eat less, exercise more. Bailor persuasively packages a wealth of research along with his personal and professional experience into an easily understood and applied framework that will change the way you live, look, and feel. For all those who feel left behind in the nutritional battles and exercise gimmicks of the last ten years, look no further, Bailor will end your confusion once and for all.

From Marion G. Volk, MHSc, Obesity researcher
This is not just another diet book. Bailor has assembled a wealth of scientific evidence showing how our healthy diet and exercise obsession are making us fat and sick. The Smarter Science of Slim is a scientifically backed, paradigm shifting, and entertaining exposé that disproves our basic ideas of eating and exercise. If you buy one health book this decade, make it The Smarter Science of Slim.

From Dr. Steve Yeaman, Newcastle University
The Smarter Science of Slim is both fun and informative. It challenges the central dogma of diet and weight control and provides a sensible alternative to the current less food, more exercise strategy. Bailor provides a compelling, simple, and practical solution to the challenge of obesity. Try it!

From Lindsay Vastola, CEO Body Project Fitness and Health
From preface-to-conclusion, Bailor cleverly articulates the misinformation that has inundated Americans views on fat loss for the last 30 years. His book is not just an enjoyable read, but his ability to incorporate scientific-backed research with his no-nonsense, often humorous at times-approach makes this a book every intelligent American should read, especially those who are frustrated with yo-yo dieting and unsuccessful attempts at fat loss.

From Maik Wiedenbach, World Cup and Olympic Athlete, CEO of Adlertraining
As a World Cup and Olympic athlete I have read hundreds of health and fitness books; Bailor s work stands alone. I have never seen such a simple and entertaining presentation of so much fat loss science. Debunking the myths sabotaging the weight loss efforts of millions, Bailor will change the way you think of fat loss and the way you look in less time than you ever thought possible.


About the Author

More info: JonathanBailor.com

Jonathan Bailor has a proven track record and a passion for solving tough problems. He is an accomplished public speaker with a knack for entertaining while he educates. Bailor speaks to and consults with Fortune 50 companies and has done so for the past decade. As an entrepreneur, Bailor has started successful businesses, authored the critically acclaimed book The Smarter Science of Slim, produced a promotional magazine, helped develop a radio show, holds more than 20 U.S. Patents and invented the marque feature in Microsoft Office 2010.

Bailor became an exercise and fitness devotee early in his life, spending hours in the gym and carefully monitoring his diet and exercise. As a personal trainer, he worked closely with clients who would achieve the results they wanted as long as they spent countless hours exercising and followed restrictive diets, but without constant coaxing to eat less and exercise more, would inevitably harm their health and gain back more weight than they lost. Bailor shared the frustration of his clients and carried the burden of recommending a lifestyle that was not sustainable. He began to suspect that much of what society had been told about diet and exercise was based on trendy opinions spurred by corporate advertising hype, rather than scientific fact.

Thus began Bailor s most intensive work - a ten year odyssey to analyze thousands of scientific studies and interview top medical researchers regarding the proven science of long-term health and fat loss. Upon discovering a disturbing disconnect between what the scientific community had proven about wellness and what we as a society are told, Bailor committed his life to work with top doctors and scientists around the world to make the research he gathered accessible to everyone.

Ten years of collaboration, over 1,100 research studies, and more than 10,000 pages of scientific research later comes The Smarter Science of Slim, which bridges the gap between the scientific world and the everyday world, dispels the myths and marketing that have fueled the current health care crisis, and provides a proven lifestyle for lasting wellness by focusing on quality of food and exercise and then eating more and exercising less but smarter.

When he is not consulting or speaking, Bailor works as a senior program manager at Microsoft. He graduated Summa Cum Laude and Phi Beta Kappa from DePauw University where he studied economics, philosophy and computer science. Bailor currently resides in Bellevue, Wash. with his wife.

By Jennifer Smith VINE VOICE on November 5, 2011
Format: Paperback
There are probably 50 trillion diet books on the market, so my hat is off to Mr. Bailor for jumping into the fray and getting his message out about the how and why of fat loss and keeping it off.

I am not a fat person; I am a flabby person. I am 5 feet 7 inches and weighed about 145 and I had been trying to lose the same 15 pounds literally for 15 years. A couple of years ago I had some weird GI problems that made it almost impossible to eat or drink and I went from 155 to 145, but since then I have been stuck.

I have read so many diet books I can't even name them all, but this year at age 45 (sigh...) I realized that my weight problem is three-fold -- self hatred toward my body led to a fear of food which led to disordered eating patterns. I also have several food allergies/sensitivities which have turned me into a picky eater. So through the years I have read diet books and done the low-fat/high-grain/walk-5-miles-a-day/starve-yourself-Saturday/everything-in-moderation programs that were so big in the 90s and early 00s. Heck, I'm not even religious, but I tried the Hallelujah Diet! Yet the flab remained, and the older I get, the more tired I am of treadmills to nowhere.

So when Mr. Bailor sent me an advance look at his Science of Slim book I was eager to take a look. It takes awhile to get through as it is pretty thick and crammed with studies (you will feel a new level of compassion for rats after you see what scientists put these poor creatures through) that show our girth is not as easily related to our sedentary/high-fat lifestyles as the latest Health and Nutrition news program would have you believe. Heck, I walk at least 60 minutes a day with my siberian huskies and my diet was basically bread, peanut butter, tofu, and fruit.

Do you believe science supports that..?

~~You can eat more if you eat SANE foods--and be satisfied and lose weight.
~~You can exercise less if you exercise smarter--and get fitter than with hours of gym work.
~~You may be metabolically totally screwed after "starvation" deficit dieting
~~A calorie is not just a calorie
~~Your body works to hold onto particular set points--and that set points can be altered

Are you skeptical that...
~~Big business is not your diet friend.
~~And neither are government guidelines.

I can tell you that I wish, oh, I wish, this book had been around 4 years ago when I was in a quandary about dieting/weight loss surgery, stuck in that "starving obese person" mode. I had to experiment on myself over years to hit upon a formula that worked, and ended up very similar to what Mr. Bailor's science-round-up recommends.

I envy those on the weight loss journey who have this book as a guide. No stumbling. Just some science and good advice, right off the bat.

I've been reading this book slowly since a couple weeks back. I have a notebook full of notes on the research/research facilities/researcher names/conclusions/highlights. This is totally a serious matter for me. I was 300 lbs. I'm now, as of this writing, 177 lbs, and I want to be 160 lbs or less. I'm middle-aged, post-menopausal, hypothyroid, auto-immune afflicted, have osteoarthritis (in joints from years of morbid obesity), a torn ligament in one knee, and totally was terrified of what this book might say about exercise.

Well, there are two main issues addressed in the book for getting slim in the smart way. The eating. The movement.

First, the eating is actually a snap.

I was sent a free copy of this book by the author to review.

The research here is impeccable. It is a proven fact that our current obesity epidemic us caused by eating too much carbohydrates, specifically sugars and starches, and NOT by eating too much fat or protein, too much meat, or simply too much. These facts have been available since the days of the original Atkins diet, and this book does an excellent job of pulling together all the scientific research to prove that eating fewer starches and more fat, protein, and leafy greens is the road to permanent weight loss. The theory that all calories are created equal is clearly disproven.

The emphasis on lots of exercise is also shown to be the wrong approach, as most of us can attest to: the more you exercise, the more you eat, and no one can burn off enough calories to lose weight.

So in terms of the Why and What of weight loss, this book is a clear winner.

Where it is lacking is in the How, and it's for this reason that I give it only 4 stars. Take the question of cultures that are rice-based. This book brings up that question and basically says, Never mind, don't worry about those people. But maybe you ARE one of those people. Maybe you are Asian-American, or Hispanic, or even Italian-American, and for you, a meal is built around rice or pasta. Well, the author has nothing to say to you except, Change how you eat. But how? How do you commit to a lifetime of eating in a way that is really different from the way your entire family eats? What does a meal look like in this new approach to eating?

The helpful suggestions were not helpful to me--eat whey powder? buy a freezer? Shop at Costco?
