True Because they use weight charts to keep track how much they gained and how much people have lost, especially at Hospitals.
The height weight chart is used to check if you're the right weight for your height. The statement that height weight charts are effective for adults, teens and adolescents is false, because the chart isn't suitable for children or people under 18. For teens and children under 18 years the Body Mass Index is suitable. The BMI healthy weight calculator is suitable for adults and children.
