I've read Marks Daily Apple, and also some of the experiences of people who go lower-carb or "more primal" than he does. It's interesting, because some of those people, after weeks or months on even zero carbs, begin gaining weight, or being seeing their blood sugar do unexpected things.
The thing to remember is that human beings are actually incredibly adaptable, dietarily. As we spread out around the world we occupied thousands of ecological niches, each with very different nutrients available, and every place human groups thrived, they did it by building a diet that their bodies could use out of what was available. These "natural" diets could vary widely in their protein/carb/fat makeup, because over time, digestive processes will adjust to very different diets. There were Native American groups that had dietary taboos against fatty fish and fatty cuts of meat because their systems couldn't handle it after months of lean bison and fruits, while their neighbors 100 miles away gorged on salmon fat for weeks at a time.
Long story short, its highly possible that as your body gets used to a certain proportion of nutrients, if it feels the need to gain weight (for hormonal reasons, among others), it will change how it processes what you are eating in order to put away fat and increase your body fat percentage to the level your body is seeking, and it will do this whatever the proportion of carb/fat/protein you take in.
