Short Daily Walks Not Enough to Fight Fat
15-minute walk or other small increases in daily
exercise may not be enough to prevent obesity, Swiss
study, found such short walks don’t burn off enough
daily calories to compensate for the yearly weight
gain seen in the increasingly overweight populations
of a number of countries.
Some experts suggest people can
prevent obesity by cutting 100 calories out of their
daily diets or by doing enough exercise each day to
burn off that amount of calories.
But the Swiss researchers say
burning off those 100 calories takes more exercise
than people may think.
specific goal is to approach expending 100 calories
a day through walking, the duration should be closer
to 60 minutes for slow walking and 30 minutes for
moderate or brisk walking.
He and a colleague reached
this conclusion after examining data on the normal
physical activity of adult residents of Geneva.
