Most major movie stars have abs that look as though they were sculpted in Michelangelo's studio. According to CNN, some stars reportedly use prescription drugs that quicken the metabolism to lose weight fast. Others practically starve themselves for days through an intense "cleanse." There are those, however, who eat a diet of sensible, natural foods and undergo a regular exercise routine to achieve a small stomach that looks great on the big screen.
Changing their diet is the first thing stars do to get a flat stomach, according to trainer James Duigan, British personal trainer, who counts Elle Macpherson and Hugh Grant among his clients. He recommends eating organic foods and healthy snacks, removing all processed foods from your diet; drinking 2 to 3 liters of water per day and quitting alcohol and carbonated drinks. More specifically, Cameron Diaz's trainer Teddy Bass says to cut all white carbs, such as bread, baked goods and rice.
There are a wide range of exercises celebrities do to flatten their stomachs. These include intense routines such as Bradley Cooper's one hour a day in the gym switching off between cardio-focused, strength-based, and core-building exercises. Diet and fitness expert Harley Pasternak has his clients, such as Lady Gaga and Jennifer Hudson, do a less strenuous routine on a regular basis. In "Marie Claire" magazine, Pasternak recommends doing three sets of 20 double crunches, trunk twists and side bends with a dumbbell in one hand three times a week.
CNN reports that some movie stars, including Paris Hilton, are said to use prescription drugs to lose weight fast and achieve a flat stomach. Adderall, for instance, is a drug prescribed to treat attention-deficit disorder, or ADD. However, the drug was touted as a diet pill when it was first marketed in the 1960s and 1970s. It speeds up a person's metabolism and reduces hunger cravings. Scott Isaacs, M.D., an endocrinologist at Emory University School of Medicine, strongly recommends against taking this drug unless a doctor has prescribed it for ADD.
Cleansing diets are another way celebrities lose weight and get a flat stomach fast. Cleansing consists of fasting or drinking and eating concoctions containing vitamins, nutrients and sometimes diuretics but very few calories -- in some cases as little as 1,000 per day. Trainer Gunnar Peterson, who trains Jennifer Lopez and Penelope Cruz, admits cleansing can help you lose up to 5 pounds fast. However, Bonnie Taub-Dix, a registered dietician with the American Dietetic Association, says most of the loss is water weight; people who cleanse also tend to put the weight back on very quickly after they stop the cleanse.
