The secret lives of the rich and famous have long held the interest of the American public, and this is especially true when it comes to their fabulous figures. It's rare that one can go through the day without seeing a feature on Angelina Jolie's luscious lips, reading an article that mentions Kim Kardashian's ridiculously well-known behind, or hearing a sound bite that talks about First Lady Michelle Obama's terrifically toned arms. It's no wonder, therefore, that American women are consumed with thoughts and concerned about their own figures and are curious about what celebrity diet plans are currently in vogue.

Very often celebrities claim in interviews that they get their curvaceous forms simply by eating healthy and sticking to a no-nonsense exercise routine. However, that doesn't stop many women from picking up every magazine at the grocery check-out stand that claims to have the latest news in popular celebrity diet plans between its cover. The weight loss industry is a multi-million dollar industry - and for good reason.

Additionally, we know that most famous women who claim they get their tight, taut bodies from consuming healthy foods and engaging in regular exercise are likely telling only part of the truth. It's true that some of them have great genetics in their favor, but it's just as true that a lot of these wonderful women also devote a lot of their day to working toward looking their best both on and off camera. It should come as no surprise, then, that celebrity diet plans are more than just marketing ploys: they're real, and many famous females swear by them.

Celebrity diet plans can take many forms. In the last decade many well-known women have relied on popular plans like South Beach, low-carbohydrate, macrobiotic, vegetarian, and many other diet programs to get or maintain beautiful bodies. Still others have stopped planning their own meals altogether, relying instead on companies that deliver small, well-balanced and nutritious dishes to their doorsteps several times a day. And still others incorporate strenuous exercise, natural supplements and pills that promise weight loss (or a combination thereof) to shape their spectacular bodies.

Finally, some famous females have been proud to detail their weight loss journeys in front of the world. For instance, stars like Valerie Bertinelli, Phylicia Rashad, Kirstie Alley and Marie Osmond have lost dramatic amounts of weight by pairing regular exercise with the popular Jenny Craig system, thereby adding this well-known diet program to the list of celebrity diet plans to which "regular" women have easy access. Additionally, sports superstars Dan Marino, Don Shula and Scott Conover have all sung the praises of the popular Nutrisystem program.
