Souping is the new juice cleanse, and for good reason: "Soup is a fabulous food. It's hydrating and fills up your stomach, so eating it before a meal can curb your appetite," says Taub-Dix. In fact, research shows that a soup appetizer can reduce the number of calories you eat at a meal by 20 percent. That said, there's no reason to consume only soup. (You're not going to eat only soup for the rest of your life, right?) Instead, make it an addition to your diet and you'll reap the benefits. This recipe may even help you live to 100.
First you'll meet with a consultant, then pick out your own menu of Jenny Craig food. (Meals are designed to be lower cal versions of what you love, like chocolate shakes, pancakes, and burgers.) The combo of social support plus portion control is a fat-busting duo, helping dieters lose nearly 5 percent more weight after a year versus dieters in a control group, according to the same study that evaluated Nutrisystem. It's so promising that researchers think docs should recommend Jenny Craig to their overweight patients. Besides: no cooking. Score!
