2.25 Energy and Diet

Understand that energy requirements vary with activity levels, age and pregnancy.

If we had a graph plotting energy on the y axis and the age on the x axis, we would see an upwards trend of demand for energy from baby to adult and then decline when it reaches the elderly stage. This will be modified to the activity of the person, such as whether they require lots of energy doing work or whether they exercise regularly.
