Eat at home more often than you eat out

Poles typically spend only 5% of their family budget on eating out. According to U.S. Department of Agriculture statistics, the average American family spends 37% of its food dollars at restaurants and fast-food joints.

To save money and pounds, start tracking how often you eat out and how much you spend each month, and gradually cut back. "People who don't cook at home tend to eat less healthy food and be heavier than people who do," says journalist and activist Michael Pollan. "In fact, the collapse of cooking in a society tracks very closely its rise in obesity."
