4. Don’t shop when you’re hungry
If you shop for groceries when you’re hungry, everything will look good and you’ll wind up buying more food than you intended. You’re also more likely to buy high-calorie junk food when your stomach is growling. Always try to get in a snack before you leave home. That way you won’t be tempted to buy too much. This approach may help your waistline too. A 2013 study found that hungry people chose more high-calorie foods than those who ate just before shopping.
