Note that the article seem to mention the calorie intake of ederly
peoples.
It is well known that as we age, we eat less and less. My father .for
example have been a big meals eater most of his life , but now that he
is 75
he just get content with few fruits and a salad a day.
i don't know the physiology behind this little calorie intake of
ederly
people, even when they are actif and energetic like my father's father
was.
This grand father was doing  exercises 1st thing  in the morning,( at
80 he
was still able to bring his foot behind his ear, something that i
don't
remember  ever,  having being able to  do ...)  was maintening a big
garden,
and was riding his bike all over the places in his village and was
eating
very small portions of food.
