Most weight-loss attempts fail because of poor planning. If your refrigerator and pantry lack a variety of healthful, lowcalorie foods, you’ll grab whatever is handy when you get hungry. If you buy chips, candy, ice cream, and other fattening treats when you shop, that’s what you’ll eat when your blood sugar dips and makes you hungry. So if you shop a little smarter, you’ll naturally eat the good stuff when you arrive home as hungry as a bear.
