Yes, but if you look at studies for the vast majority of people the common denominator across diets like the GP mentioned is improved diet quality and eating less. Most people don't need to remove carbs themselves. Sure, pasta is refined grain etc, but if you are well and not overeating then there's nothing wrong with it. A (if not the) primary problem is that people tend to overeat things that contain lots of carbs and/or fats that fail to satiete.
To your point, restricting carbs in those diets is one of the keys to eating less. You mention (and rightly so) that "people tend to overeat things that contain lots of carbs and/or fats that fail to satiate": if there aren't carbs in the mix, fats (and protein) satiate more quickly (and for longer) than when accompanied by a hefty portion of carbs.
'djsumdog pointed out diets that many have found successful and meet the requirements that 'georka mentioned, moving the conversation forward constructively. If you have diets suggestions that also meet those requirements, or constructive criticism that 'georka's or 'djsumdog's points are off base and have alternatives, great!
As for "Most people don't need to remove carbs", at least in the US, while complete removal isn't necessary, I believe many could benefit from restricting their carb intake, keeping everything else constant (as long as they're getting adequate protein and vitamins/minerals). Whether that's due to shifting the macronutrient balance or just from the reduced caloric input, they should see a benefit, and likely will not feel hungry. It sounds like you agree that low carb diets can benefit people. In that case, if you have other diets you prefer, offer them up constructively (though likely elsewhere, as this is now well-off the beaten path of this thread).
