Funny you should ask that question, as I happen to know of a FANTASTIC resource for weight loss science.
The e-book, real easy weight loss is CHAULK full of weight loss science, but if you want some free information, take a look at our home page. You will see a short summmary of many of the weight loss and diet programs out there today.
If you're really interested in losing weight as fast as possible while keeping it off, I explain why and how my weight loss program works in my new weight loss and diet program.
