Sad, even if completely unsurprising statistics. Human bodies have evolved to be incredibly efficient, which worked really really well for thousands of years when food was scarce. The food is plentiful now. Average healthy adult male only needs 2000 calories a day, females even less. A double cheese with french fries and a coke can easily top 1000 calories. Add all the snacking junk food that people munch on during the day - juices, soda, candy, chips, ice cream, lattes, and that easily pushes you over 2000 calories. From my personal experience, if I want to stay in a relatively healthy shape I cannot have any junk food whatsoever. I exercise though, but once again, exercise doesn't burn as many calories as people think it does, I bike about 25 miles a week plus I do bodyweight exercises at home. This exercise is the only thing that allows me to have some chips and soda or a small bar of ice cream once a week.
