He wrote a paper describing his experiments on weight loss, and the link to the paper is here.
There aren't a whole lot of complicated rules. Creating Passionate Users writes:
It is almost impossible to describe what this "diet" (it's not really a diet) does. (All links are at the end of this post) A UC Berkeley professor named Seth Roberts claims to have found a way to trick the legacy brain into thinking it needs to weigh less. (Which means "lower your set point", for those who are familiar with that term)
It does not cause you to suddenly burn more calories.
It does not increase your metabolism.
It is not a drug.
It does not require counting calories.
It does not require changing what you eat (although for many people, it will anyway)
It does not require exercise (although I'm always going to strongly recommend it!)
[Update: It is based on quite a lot of different scientific research (rat studies, especially) that the author has managed to piece together into a theory and approach that works.
It is not simply a psychological trick.]
It claims to do just one thing – cause your body to want/need less food. Period. In other words, you know that feeling you have after you've eaten a huge dinner and you think, "I'll never eat another bite ever again" – this so-called "diet" makes that feeling happen much earlier, after a much smaller meal. Quite simply, it reduces your appetite, but in a really freakish way. It is not an artificial appetite supressant; it works by using your body's natural appetite supressant – the desire to keep you at a particular weight.
So why does Creating Passionate Users address this program? It has to do with the approach:
You have a legacy brain. We've talked about that a lot on this blog, and in my presentations. Your brain thinks you're still living in a cave. Although your mind knows you're in the 21st centry, your brain never got the memo.
Your brain thinks that food is scarce for you, so it better hang on to it. In other words, for almost all adults (especially in the US), our brain wants us to be weigh more than our conscious mind wants. The brain never got the memo about how you probably aren't going to starve this winter.
Given how interested we are here into hacking and creating workarounds for the legacy brain issues, a new diet book that claims to take this approach got my attention.
Update: Although everyone seems to recommend buying the book, here's a link to a blog created for the diet – how to do it.
It might be worth a try.
