With guidance and monitoring, the trend now is
that children and teenagers shall change their life habits
(diet and physical exercise), even if they are not able to
carry out all the instructions. Here I stress that it is very
important to give praise, even for the smallest changes,
such as changing a tasty salty snack for fruit while at
school, to encourage them to improve. This treatment
is a long process, and the prevention of metabolic
disturbances is a priority in public health. The change
can even start during the nursing appointments at the
basic health units(19).
