It's not overeating that's the problem—it's our lack of movement.
Researchers at Stanford School of Medicine reviewed data from 1988 to 2010, concluding that average calorie intake has remained largely stable during this period.
Movement Patterns
Our activity levels have changed dramatically. Leisure-time exercise has plummeted: in 1988, 19% of women reported no physical activity in their free time, rising to 52% by 2010. More people now work sedentary jobs with little physical demand.
The Solution?
Boosting exercise to match calorie intake is tough without an active lifestyle. Tim Lobstein, director of the World Obesity Foundation, recommends adapting our diets to our increasingly sedentary lives instead.
