We all know that Americans have put on a little weight over the last few decades. The solution, we hear, is to exercise more and eat less. Well, a new study suggests that, really, eating less is the only viable option.
It seems weâ€™re not much less active now than we were in the 1970s. So how can we hope to return to those leaner days?:
[C]hildren would have to cut their intake by about 350 calories a day — equal to one can of fizzy drink and a small portion of French fries, and adults by about 500 calories — the equivalent of a Big Mac burger.
Alternatively, children would have to walk for an extra two-and-a-half hours a day, and adults for nearly two hours.
Exercise is still useful in losing weight. But since few of us have the time for a two hour walk, I suppose putting down this Big Mac might be a better start.
