Download As PDF : What Is Fat For? ReThinking Obesity Science Ignatius Brady 
Obesity science has reached a crossroads The carbohydrate hypothesis is poised to overtake “calories in, calories out” as the predominant understanding of weight gain. Physicians, dietitians and trainers have come to treat “carbs are bad” as a new gospel, preaching a lifestyle that strays very far from the true scientific consensus. In "What Is Fat For?" Ignatius Brady, a weight loss physician and science writer, presents a fresh perspective on obesity based on critical new research that has gone largely overlooked.
The protein leverage hypothesis holds that neither dietary fat nor dietary carbohydrate “cause” us to gain weight. The obesity debate is re-framed as an imbalance between “protein” and “non-protein” energy. This imbalance has caused a widespread human adaptation the obesity epidemic.
In a thorough yet readable style, the book takes the reader through normal human weight regulation, the time frame needed for weight loss, and what’s missing in the “carbs are bad” thinking. This is not a diet book, but a scientific exploration of the inner workings of human biology and our interactions with the modern nutritional environment. The question, “What is fat for?” drives this narrative, which takes nothing for granted, analyzes all possibilities, and presents detailed evidence for the reader’s best judgment. Biases are overturned, accepted wisdom is re-considered and new answers are discovered.
What Is Fat For? ReThinking Obesity Science Ignatius Brady
The obesity epidemic is a fascinating puzzle. There are many theories about the causes. Dr Brady makes a bold attempt at connecting the dots. Does he succeed? Hmmm, let's see.He destroys the naive view of CICO (calories in vs calories out) and presents some of the nuanced complexities. For me, this was the highlight of the book.
He accepts the role of insulin and the effects of high carb intake, but he can't quite accept carbs as a causative factor. Personally, I agree with his sentiment that low insulin is necessary but insufficient. Calories still matter.
One of his major insights is that protein intake is a huge factor. He suggests that even a small deficiency is leveraged to become a driver of obesity. We eat everything in sight until our protein needs are satisfied.
I loved his insights into the metabolic syndrome and diabetes, but some of it is speculative. I found much of the book to be INTERESTING speculation, and I found myself both wanting to argue with him and to extend his speculation with my own.
I disagree with some of his conclusions, but I LOVED his presentation and his valiant attempt at connecting the dots.

What Is Fat For? ReThinking Obesity Science Ignatius Brady Reviews
Common sense backed by good research. New insights. More questions than answers. Interested in seeing what is next from this obesity physician.
"What Is Fat For?" looks at scientific studies relating to obesity and weight loss. The author explained what he's concluded based on the studies and what he's seen in his own clinical practice. He did a good job of explaining the science in a way that ordinary people can understand it. He provided enough information about the studies that a reader can understand how he came to those conclusions.
If you want a "do this and you'll lose weight!" book, then you might be unsettled by the many unknowns that the author admits still exist. But if you desire an honest look at the topic--including his best recommendations for weight loss--then you'll probably enjoy this book. He focused on obese people, though much of the information can also apply to overweight people and preventing future weight gain.
He discussed the most popular types of diets and how the body processes the macronutrients (fat, carbs, protein). The body appears to use the percentage of protein in your diet to monitor if you've eaten enough food. He explained how this knowledge can be used to lose or maintain weight. He talked about type 2 diabetes, how fat cells are a protective mechanism, and some dangers of long-term, high protein diets. He discussed why he recommends increased activity throughout the day (rather than intense exercise), especially for obese individuals.
He revealed the truth about how your BMI affects your longevity. That chapter made me angry at BMI calculator sites as they make it sound like you should panic if you're even slightly overweight. He wrapped up by talking about fad diets, quack doctors, and such. I'd recommend this book to those interested in what scientific studies actually indicate about weight loss.
I received an ebook review copy of this book from the publisher through NetGalley.
There's no shortage of diet or weight-loss books on the market. Almost any angle or approach to the subject can be found, usually going into great details on, and justifications for, the recommended diet or program. What Is Fat For? takes a different and more neutral tack by instead exploring many different popular theories of weight-loss and diet (low fat, high protein, low carb, Paleo, etc.).
The author draws from a number of medical studies to show the evidence, or lack thereof, for each weight-loss approach, along with known potential side-effects. He also takes great care to explain the science, or at least the reasoning, behind each theory, and adds his own personal experiences and anecdotes from his career helping people with weight-loss. Despite covering so much medical data, the author has an almost conversational prose style which, combined with a tendency towards succinctness, makes for a very enjoyable read without the typical dryness of similar books on the market.
Ultimately, the author - and science - can reveal no undeniable silver bullet, but readers will be much better educated on their options for, and the impact of their choices on, their overall health and well-being. If you're looking for a good book on diet and weight-loss that has neither an axe to grind nor a user-car to sell you, this might be the book for you.
Chronicles history of diets and studies related to them. Cautions for perennial dieters.
One can learn a lot about diet. This is an educational book.
Very interesting read
If you think you understand weight loss, you MUST read this book! Ignatius Brady, MD, MPH takes a totally new approach to why we get fat and why diets don't work. If you thought Gary Taubes had solved it all, this will open your eyes. Followers of "paleo" and Atkins need this wake up call too.
Half science, half story telling, the book is smart and funny. It explains the biology and metabolism so that you finally see why obesity happens. It does not ever become a diet book or recommend a program. It just blows your mind and leaves it at that. Highly Recommend.
