The term “weight management” generally brings to mind the issue of how to lose weight, or at least how to prevent gain. But sometimes there are health-related reasons to gain weight, and one scenario where this may be the case is in celiac disease.

Weight loss (or, in the case of kids, slowed growth) is one of many possible consequences of undiagnosed celiac disease. The inflammatory response caused by gluten in people who have celiac disease undermines the body’s ability to absorb nutrients by damaging intestinal cells that are involved in nutrient absorption. When nutrients aren’t absorbed, they are not available to the body to support health and growth: malnutrition, weight loss, and/or slowed growth can result.

There are two main aspects to the recovery of nutritional status and health after beginning a gluten-free diet: 1) the healing of intestinal cells, which allows for normal nutrient absorption; 2) consumption of a healthy, gluten-free diet that provides the nutrients needed to help reverse nutrient deficiencies and that (when applicable) supports recovery of lost weight and/or resumption of normal growth in kids.

In the case of children who have celiac disease, weight loss – or a slowing of weight gain or overall growth – can be especially detrimental. While there are natural variations in children’s rates of growth and weight gain, most healthy kids generally follow the ranges defined on standard pediatric growth charts. Falling below these ranges may be associated with increased risk for various conditions, including decreased immune function, cognitive impairment, and higher risk of fractures due to decreased bone density.

It is important to work closely with your child’s or your own personal healthcare team and dietitian throughout the healing process so that follow-up, testing, and dietary advice and planning can be individually tailored. However, following is some general information to keep in mind.

An increase in calories consumed generally leads to a gain of weight, and vice-versa, reducing calorie intake generally leads to weight loss. However, re-gaining weight that was lost unintentionally (or reversing a trend of slowed growth) needs to take into account more than just increasing calories. It’s easy to add calories to the diet for example by increasing intake of common processed foods that often get caloric density from fats and sugars but which don’t provide significant amounts of vitamins, minerals, and other nutrients that are essential to health and rebuilding. When the body becomes starved of critical nutrients it begins a process of “autophagy,” which means that it starts breaking down its own tissues to provide ongoing energy and other components needed to maintain functioning. Muscle and other tissues that may have been broken down by the body need not only extra calories, but also protein sources for rebuilding. This is even more critical for children, who are not only rebuilding lost tissue, but supporting ongoing growth as well.

What does all this mean in terms of what foods to put on your gluten-free table? Let’s look at some details:
