Just to be clear, I wouldn't say that "calories are calories" in the way most people define it (meaning that only calories matter and that a person will lose exactly the same weight on 1500 calories of carbs as on 1500 calories of protein).
Calories matter, but calories also aren't necessarily "simple." For example, I learned (from careful food journaling) that I lose better on 1800 calories of low-carb than on 1500 calories of high-carb. That means on low-carb I don't have to restrict calories to the same degree as I do when on high-carb.
Since high-carb also makes me hungrier, I have the choice between eat much less and be much hungrier, or eat more/lose more/be less hungry.
High-carb really doesn't have much to recommend it except the flavor. Sometimes I WANT a high-carb food, and I decide that the extra hunger and slower weight loss is an acceptable expense to have a food I want.
As a result I generally follow a moderatealy low-carb 1500 to 1800 calorie diet. I have a high-carb 1200 to 1500 calorie diet that I will use as my "back up plan" for days when I want to go higher carb - or I'll be in a situation (such as at a family dinner where I'm not controlling the menu) in which a higher carb plan is more convenient.
Even though calories are not equal (at least not for everyone), calories still matter. I may lose better and faster on 1500 calories of low-carb than on 1500 calories of high-carb, but that doesn't mean I can eat 10,000 calories of low-carb and still lose weight.
The metabolic advantage to low-carb is limited, and may not be universal for everyone. Some people may experience more dramatic differences between the two diets than others.
The only way to tell how much (if any) advantage one diet has over another is to experiment. I was surprised to learn that comparing low-carb to high-carb eating that I could eat about 300 to 500 more calories on low-carb. It was kind of amazing, really.
Even if there were no difference, I'd probably choose lower carb most of the time, because with carbohydrates the more I eat, the hungrier I get.
In terms of calorie metabolism and hunger, some people may experience an even greater difference or no difference at all. Experimenting is all any of us have.
