<<Disclaimer: Verify this information before applying it to your situation.>> Lisa - I had the same problems after being diagnosed with celiac disease. I've discovered that the key to weight management is no different for celiacs than for everyone else - portion/ calorie control, limiting fat and saturated fat to 30% and 10% (respectively) of calories when balanced over a week, and aerobic and weight-bearing exercises. I think the problem for celiacs is usually portion control. For many years, we could eat all we wanted to without gaining, and often, losing weight. The key for your sister is to learn how much she needs to eat and exercise to maintain her desired weight. I suggest starting with a book like Fit for Life which explains the interaction of food and exercise and gives charts for estimating the amount of calories someone her size should eat to maintain her desired weight. At first she may need to count calories literally, but after awhile it becomes second nature and she won't have to. She'll instinctually know whether she has eaten more or less than desired on a particular day, and, then, can adjust her exercise and eating plans for the rest of the week accordingly. Celiacs, like all people, have to develop a healthy relationship with food. Hope that helps! Colleen Kavanagh Washington, DC [log in to unmask]
