Daily physical activity energy expenditure in
contemporary Western societies is only ~38% of
that of our Palaeolithic ancestors

Daily physical activity energy expenditure in
contemporary Western societies is only ~38% of
that of our Palaeolithic ancestors
physical activity
(Cordain et al 1998)
Physical inactivity has become one of the major
public health problems of the 21st century
(Blair 2009)
¿Somos ciudadanos del Paleolitico viviendo en el
siglo 21?
¿Serán aquellos que tienen un estilo de vida más
parecido al de nuestros antepasados los que tendrán un
menor riesgo de desarrollar enfermedades crónicas y
por tanto una mayor esperanza de vida?
