Kippy's Ice Cream Shop in Venice, California, recently offered a four-day ice cream cleanse.  Kippy's ice creams are organic, raw, and coconut-based, so they're non-dairy, Fox News reports. Cleansers got five servings of ice cream a day in flavors such as Orange Crème and Master Cleanse (which features lemon, cayenne pepper, and honey). 

While the cleanse sounds fun, it's not actually a smart choice, says Brooke Alpert, R.D., founder of B Nutritious. "Whether the ice cream is coconut-based or not, I'm very concerned about the variety of nutrients that you're getting—or the lack thereof," she says. Any time you're relying on a very limited selection of foods—instead of a variety of good-for-you options—you're putting yourself at risk for nutritional deficiencies because you can't possibly be getting all of the vitamins and minerals you need. 

Wondering about the weight-loss factor? Brent Rose of Gizmodo tried this ice cream cleanse with his girlfriend and did drop about six pounds, but he wrote that he gained it all back over the course of a long weekend. See, here's the thing: "If in some ways your meals are limited, you most likely are going to be eating less—and therefore you are most likely going to be losing weight," says Alpert. That doesn't mean it's necessarily good for you or healthy, though. "While you might lose weight, the weight comes all right back because it's not a sustainable lifestyle approach."

Rose did say that the upshot of the cleanse was the tastiness. "The ice cream really is delicious, and I'd definitely recommend it without hesitation (in small, normal-sized doses)," he wrote on Gizmodo.
