Dr. Jason Fung is a specialist in Type 2 Diabetes and obesity. The Obesity Code goes back to first principles in order to explain why people become obese, and what they can do about it.
I liked the fact that almost every bold statement in the book, of which there are many, was thoroughly researched and supported by actual data. This is not a pop-science guide with only vague foundations that “seem to make sense”. If the data doesn’t fit, Dr. Fung examines why it doesn’t, and which hypothesis would actually fit. This is tome of solid science targeted at the layman.
What I found most interesting was how complex the mechanisms controlling weight gain and loss are. I had for a long time believed strongly that input vs. output was the only answer. It seems I was wrong, or at least only partially correct. It turns out that most perceived wisdom about weight is, if not incorrect, then at least incomplete, especially if individual factors are taken in isolation. And that is perhaps the key message. You cannot take a single reaction and single it out. A holistic approach is needed.
Now to do some testing on myself.
