If we do this with every fat kid in the country, we'd have like three million kids who all weighed 3 to 5 pounds less than they do now. The cost effectiveness here is beyond reproach, is what I'm hearing. But there are known limitations for families to access and participate in intensive health behavior and lifestyle treatment. Family transportation challenges, loss of school or work time to attend multiple recurring appointments during what are typically working hours. And mismatched expectations between the family who may expect significant weight loss and pediatricians or other pediatric healthcare providers.
