Low carb works because you get into ketosis, and if you up your carbs enough, then you get kicked out of it. So you are going along well, without cravings, and losing weight, and voluntarily choose to stop it and reverse the effects? Why would you want to have cravings, and not lose any weight? Getting past the first few days is hard for some people, and I don't understand why you would want to repeat that over and over.
This would be akin to calorie cycling, which is what many people do.. they eat good for 3-4 days , and then have a huge calorie day, eating sweets, and Taco bell, or pizza. THAT doesn't work either.
Pick a level of carbs that is acceptable, and helps you lose steadily, without any cravings, and stick to it. If you cut out sugar, and processed carbs, and focus on vegetables, you may be able to have quite a high allotment of carbs. The quality of the carbs you eat matter as much as the quantity.
