Eating healthy is challenging for many people. Most will admit that swapping French fries for steamed broccoli or ordering a salad with dressing on the side is a difficult choice to make. And when your spouse or best friend orders a burger and large fries, it makes eating healthy that much more difficult. Don't let others' bad habits sabotage your efforts to eat right. Here are some helpful tips for dieting while eating or living with a non-dieter.

1) Switch to low-fat versions of full-fat favorites. Don't worry, your spouse won't notice if you start cooking with lean protein or switch from full-fat to low-fat cheese. So go ahead and use ground turkey breast or lean ground beef in your favorite burger recipe. And make your omelets with egg whites and low-fat cheese instead of whole eggs and full-fat cheese. Use nonstick spray instead of smothering the pan in oil or butter. Not only will you avoid tons of calories and fat, but your spouse won't even realize you made the switch.

2) Keep healthy snacks on hand. There is no need to have regular potato or tortilla chips lying around the house. Instead, buy baked varieties. Also, keep fruits, such as apples and pears, or nuts, such as pistachios, available as easy snacks to grab on the go. Having healthy options easily accessible will keep you from munching on unhealthy foods when you sit down with your roommates to watch TV or run out the door to meet up with friends.
