Another good tip if you like chips (crisps), see what I really like is crunchy food that is salty. Just like with cookies, "healthier" chips often aren't that much better. Even pretzels are full of simple carbs. And "processed" store bought crackers and pretzels and chips are often incredibly high in sodium.
But, what i discovered is if I take some baby carrots and sprinkle salt on them, they kind of absorb the salt and tast really salty. And they are crunchy, too. They very much do curb my craving for something salty and crunchy. Even though they taste salty, table salt does not contain nearly as much sodium as things from teh store, plus you get the nutrition benefits of carrots such as vitamins and fiber.
