Body Weight and Energy Balance
Body Weight & Energy Intake
Each variation of energy intake must be counterbalanced by an equal variation
of energy expenditure, which occurs through a variation of body weight,
so that for each individual to a definite energy intake must correspond
the body weight that produces the energy expenditure equal to that intake.
However, that same energy expenditure may be produced by very different
body weights, as well as the same body weight may produce very different
energy expenditures, depending on different body compositions. This explains
how individuals with equal body weight may have different energy intakes,
and individuals with the same energy intake may have different body weights,
and how a very heavy individual may have an energy intake much smaller
than that of another much lighter individual, and vice versa.
Body Weight & Energy Intake - Summary
In summary, energy intake determines body weight and its variations, but
the size of body weight and of its variations is determined by body composition
and by its variations.
