That, and how would they measure the energy expenditure of a really wild animal anyway? *banishes mental image of a experimenter trying to bribe a walrus with a bucket of fish*
They might be able to do this type of experiment with a caged wild animal, but the results won't be the same. That animal simply won't move as much as a real wild animal, due to a lack of space.
Doubly labelled water works for wild animals too - capture, inject it with the solution, recapture a period of time later, take a blood sample, measure the isotope concentration and work out the difference. Or you could strap instruments on it to measure its heat output and let it loose.
Shit, like j&t just said, in fact.

On average I would say I have exercised more since the 80s
But then I was only around for a year and ten months of the 80s.
We'll be understanding then. I think I do more myself too, but that's because I was a lazy teenager then, reading books all the time.

Damn books, burn them all. All they do is turn us into a culture of fat wimps. :mad: :mad: :mad:

I can't remember ever exercising in the eighties.
Oh wait...

I read an interesting article in a cycling magazine this month about losing weight and the increasing difficulty over the years due to the fact that we have to burn more off these days due to an increase of calories and portions.
For example:-
Some breakfast cereals contain 10% more calories than in 1983
Haagen-Dazs Belgian chocolate ice-cream contains 16% more calories and 26% more fat than in 1994
Jordan's original crunchy cereal bars contain 16% more calories than in 1986.
Portions are generally getting bigger. Crisps (potato chips) increasing from 33g to 55g and cereal packet up from 30g to 50g along with the extra calories of course.
