Echoing what getfit1980 said, Taubes' book is about the biology of obesity. I don't agree with everything that's in there (including Taubes' contention that exercise is pointless for weight loss), but it does form a good basis for figuring out how to control dietary variables to keep weight down. If you see any of my posts in other threads, you'll see that we're on the same page regarding calories in vs. calories out. There's no doubt that calories matter. Mike already has a thread to your point called something like "hey fattie, excuses why you are fat" for people to air their misgivings. After you've admitted your excuses, figuring out what you're going to do about it is the next step.
I think we need to step back here a moment. A lot of people conflate Taubes' work with the paleo community. It's easy to do since a lot of people who start with GCBC eventually make their way into paleo. But it's not the only theory of obesity floating around. Stephen Guyenet has a pretty well articulated food reward theory that IMO needs some more scientific rigor at this point (modern processed foods release too much dopamine, essentially turning them into dietary cocaine). Taubes' insulin hypothesis is on better scientific footing at the moment.
That said, I also think that from the outside, there is rightly a view that paleo evangelists live in a bubble of cognitive dissonance. I would argue that the people that are most vocal about paleo are those who have recently tried it (the "book version") and had success; these are people who have done numerous "diets" in the past and paleo is another "diet" that worked for them. As a result, for them there is only one "paleo diet" which excludes certain foods and includes others.
This cannot be repeated often enough, but THERE IS NO ONE, SINGLE ALL-ENCOMPASSING PALEO DIET. Arctic Inuits did not eat the same food as tropical islanders. Heck, even among islanders, there are nations where coconut and fat cuts of fish and wild pig were staples (very high fat), and other nations where root vegetables formed the base of every meal (very high starch). Also, most cultures outside of America and Europe supplemented their diets with insects. So it's fallacious to assume, for everyone, that there is only THE paleo diet as written. Or what I like to call, the "book version."
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
