Background: Family-based behavioral treatment (FBT) is the most successful weight-loss treatment for children with overweight and obesity, however, long-term success is only achieved by a third of children over time. The use of foods that induce satiety, such as eggs, could improve adherence to calorically restricted diets in children and improve outcomes. This study explored the consumption of eggs (FBT+egg) or cereal (FBT+cereal) for breakfast as part of an FBT program, when breakfast foods were provided to families. Methods: Fifty 8-12-year-old children with overweight and obesity and their parents were randomized to a 4-month FBT+egg or FBT+cereal treatment program. Families were provided the ingredients for their assigned breakfast at each treatment session, and instructed to consume the breakfast a minimum of 5 days per week. Families attended assessments at baseline, post-treatment, and 4-months post-treatment. Results: Results showed that both treatments were well liked, FBT attendance was similar, and there was high compliance with consumption of the specified breakfast. Children experienced moderate weight loss at post-treatment [-0.11 standardized BMI (BMIz)] through 4-month follow-up (-0.09 BMIz), with no statistically significant differences (mean difference -0.05 BMIz, 95% confidence interval -0.19 to 0.09) observed between egg and cereal conditions across any anthropometric or appetitive measures. Conclusions: The use of eggs for breakfast in children enrolled in FBT was well tolerated, and future studies should include larger samples and longer follow-up periods to assess the potential differential effects of prescribed breakfasts on children's weight and eating behaviors.
