Based on intake and physical activity data, the increase in
the number of obese children is likely the result of a combination
of children and youth eating more calories than
they are using through daily physical activity. Weight gain
results when energy expenditure is consistently exceeded
by energy intake over time. Achieving energy balance is
important for children so that energy intake is equal to
energy expenditure while supporting normal growth and
development without promoting excessive weight gain.
Therefore both are important components in reversing the
obesity trend. More research is needed regarding their relative
contributions to weight gain and obesity prevention.
