children for obesity and providing them with appropriate counseling.

healthier weight, and researchers do not even fully understand the factors
that contributed the rapid rise in childhood obesity in recent years. 4.______

initiative, there is also growing demand for programs help children who 5.______

some products for children. 7.______
