Frequently asked questions
Should I put my child on a diet?
Strict dieting is not usually advised for growing children. The goal is healthy habits for the whole family and, often, holding weight steady while the child grows into it. Your doctor can guide a safe plan.
Is childhood obesity really a health risk?
Yes. It raises the risk of type 2 diabetes, high blood pressure, fatty liver and joint problems, and often continues into adulthood. Early support has lifelong benefits.
