Your response to this question most likely is lack of exercise and eating too much food. Well, you may be half right. Research seems to support the finding that sedentary behavior rather than eating too much food is primarily involved in contributing to the prevalence of overweight and obese Americans today. The American Journal of Medicine has concluded from reported data that Americans are more sedentary now than they were 20 years ago. Almost 1 in 5 women reported not being physically active 20 years ago, whereas over 1 in 2 women reported being mostly sedentary today. In men, 1 in 10 reported not being physically active 20 years ago whereas today, over 2 in 5 men reported being mostly sedentary. But here's the interesting part, average daily caloric intake throughout this time period did not significantly increase. Therefore, one can surmise that it's a lack of physical exercise that's causing our skyrocketing obesity rate and not gluttony behavior.
BOTTOM LINE: Sitting for long periods of time is not recommended if you want to avoid bodyweight (i.e., fat) gain. Take short breaks every hour and go for a walk to get the blood flowing and lessen the risk of heart disease (still the number one killer of Americans), stroke, diabetes, and other chronic diseases.
