Many people believe excess (refined) carbs are partly or mostly to blame, but it's not quite clearcut.
The evidence points strongly into that direction.
Everything that stimulates the appetite potentially causes overeating. All types of food, incl. protein- or fat-rich food, can be stimulating. Different people have different tastes too.
Carbs are Orexigenic.
Well, people used to a paleo-like diet may love meat and find it "almost impossible" (i.e. not fun) to eat lots of carbs. What people like has to do with what they're used to, what diet they were raised with, how food is prepared and spiced, etc. What people like is not in any case an indicator of what diet is good or bad for them.
Sorry, you are attacking a straw-man here. What I was saying is that it is much easier from a physiological point of view to digest carbs than protein and fat. This is not a matter of taste.
The evidence points strongly into that direction.
Cite please? That's what this post asked for.

True, but there are other ways for food to induce overeating. For instance, salty food makes you drink more, and you may be drinking calorific beverages. Some theories hold that food becomes associated with reward value, making people eat more of it over time, regardless of its direct affect on appetite. Fat is calorie-dense, so it's easier to eat more calories of it before feeling sated than with carbs. Food may modify the onset of sat...
I recently came out against paleo in the open thread, and realized that I probably haven't yet heard the strongest arguments in favor of a paleo diet. So, what are said arguments?
EDIT: Or more generally, why should I eat less carbohydrates and more protein / fat?
