The reality star, who was shot exclusively for Life & Style, shed 15 pounds without skipping a beat. The first order of business is to eliminate carbohydrates. "I miss it terribly, but I no longer eat pasta," she tells Life & Style. "I eat my veggies and strive to maintain a healthy lifestyle." Sammi lost weight by going on an elimination diet based on foods that cause reactions in her body when she eats them. She eliminated wheat, corn, and many other common ingredients used in baking because they contain proteins that trigger an immune response when she eats them. This method takes advantage of your body's natural reaction to certain foods. If you are sensitive to milk products, for example, then eating cookies will cause you to break out in hives. By avoiding these foods that cause allergies, you are essentially self-medicating with an elimination diet, which allows you to identify the specific food or group of foods that are causing problems. Once Sammi had identified the offending items, she could start adding them back into her diet one at a time to see how she reacted. If she ate a bowl of cereal made with wheat flour again, for example, she would know that was the cause of her allergy-like symptoms. Then she would stop eating it and get ready to try something new! People tend to wonder what happens to your stomach muscles when you lose weight.
