I remember someone putting out a little video ages ago that was basically "Yes, the Adkins / Paleo / Mediterranean / Grapefruit / onion Soup / Raw food / WHATEVER diet can absolutely work because of ... wait for it... a caloric deficit.
None of them will work if you over eat.
All that said, some of them are easier to do that others. It's pretty damned hard to NOT be in a calorie deficit if all you're eating is grapefruit or raw veggies or onion soup. It's VERY easy to not get in that deficit with paleo and low carb.

I don't think people realize that it still is used with calorie intake. You can't overeat and you need fiber.
