The promises: Clear your mind and shed those last few pounds in the three days before your big day.
The perks: With their extremely low calorie count, these cleanses could conceivably help you bid adieu to that final stubborn bit of fat, Smith says. Spices such as cayenne may help control appetite, Brown notes, while the fennel, ginger, and dandelion in some of these juices act as mild diuretics, banishing water weight and belly bloat.

The squeeze: Instead of losing weight, some women may gain on a juice detox, Canfield says. The reduced fiber and water content of juiced foods leaves you less satisfied calorie for calorie, meaning you may be tempted to chew actual food—and likely not the healthiest kinds. Smith also doubts you’ll feel less stressed, as no evidence has linked any ingredients in these juices to emotional benefits.
The verdict: Cleansing could conceivably fit into a bigger pre-wedding slim-down routine, Brown says. Start three to six months before you walk down the aisle by exercising more, adding more vegetables and fruits to your diet, and cutting back on sugar and alcohol. Do the three-day cleanse a week to five days before your wedding, keeping your exercise light since you won’t be getting enough calories to fuel major workouts. Return to whole, healthy foods a few days before you say “I do” to make sure you have enough energy for the rehearsal and any other pre-wedding events, as well as the actual wedding, of course, Brown says.
