Weight and Energy Intake & Expenditure
The obese patient eats on the average more
than the lean person, but not much more.
In our population, the difference in total
energy expenditure, and thus of energy intake, between a group of 34 lean
subjects with mean stable body weight of 65 kg (range 55-83 kg; mean TEE:
1,989 Cal/day, range 1,167-3,176) and a group of 86 obese patients with
mean stable body weight of 124 kg (range 90-203 kg; mean TEE: 2,246, range
1,322-5,064) was little more than 250 Cal/day. Furthermore, due to the
enormous interindividual variability, caused by many variables other than
composition of weight change, the overlap between the two groups was such
that it was well possible for a subject much heavier than another one
to consume and eat much less than the latter.
