Objective: Recommended iodine intake is 150 μg/day in adults, 220 μg/day during pregnancy, and 290 μg/day during lactation. Individuals exclusively consuming restricted diets as part of a weight loss program may be at risk for mild to moderate iodine deficiency. To assess the iodine content in meals and snacks from three U.S. commercial weight loss programs, all of which are intended to be the sole source of dietary intake during the desired weight loss period.Methods: The iodine content in the products representing one week of all meals and snacks from three U.S commercial weight loss programs was measured by spectrophotometry. The measured total iodine content in one week's worth of food from each program is reported as an average level per day.Results: 53 total items were analyzed [29 different items (7 breakfasts, 7 lunches, 7 dinners, 6 snacks, 2 desserts) from Jenny Craig; 21 different items (7 breakfasts, 7 lunches, 7 dinners) from Nutrisystem; and 3 different items (1 breakfast, 1 lunch, 1 dinner; each to be intended to be eaten daily for one week) from Medifast]. Daily iodine content (mean ± SD) of meals and snacks from the weight loss programs were 34.2 ± 1.2 (Jenny Craig), 12.2 ± 0.7 (Nutrisystem), and 70.1 ± 1.1 (Medifast) μg/day.Conclusion: These results indicate that the dietary content in the foods from three U.S. commercial weight loss programs is far less than the recommendations for iodine intake of 150 μg/day in non-pregnant, non-lactating adults. Individuals following each weight loss programs should be advised to take a multivitamin containing 150 μg of iodine daily.
