The chief cause of obesity is physical inactivity, which is rapidly spreading from North America to the rest of the world. About 31% of the world’s adults, or about 1.5 billion people, are almost completely sedentary, meaning that they do not meet the minimum recommendation of 150 minutes of walking or other moderate activity per week, or about 20 minutes a day.
Teenagers are faring even worse. More than 80 percent of young people ages 13 to 15 worldwide are not getting the hour a day of vigorous exercise recommended for their age group.
Those of us that want to exercise regularly must realize that we are working against cultural forces. Stay focused on the best way to live for yourself.
