Plan active get-togethers
Dates don't have to revolve around food. Go for a walk in the park, followed by a picnic. Play a game of tennis and then share a treat. Grab a cup of coffee before checking out a local museum.

Safeguard your kitchen
If you're living with your partner, you're also living with his food. Give him a cabinet up high where he can keep chips, cookies and candy. You might be tempted when your boyfriend eats these foods in front of you, so make sure you have something satisfying to snack on. If he's eating buttered popcorn, air-pop some for yourself or have a fudgesicle while he indulges in ice cream.

Find a support system
"If your boyfriend is not supportive of your diet, find at least two other people in your life who are," says Antonucci. Seek out a coworker you can share a healthy lunch with, a running buddy or a girlfriend you can call to distract you from the ice cream in the freezer. Surrounding yourself with those who encourage your healthy lifestyle and offer positive feedback will help you make better food choices so you'll love your body as much as your beau.
