7. Seek out support. Adopt an eating plan that's right for the whole family so you don't have to go it alone. If they won't join in, get professional help from a registered dietitian or your doctor—research suggests solo dieters are more likely to give up. Support is often key to success.
8. Reward yourself. But not with food. Think about how much you typically spend on junk food, says Liskov: "At the end of the month, if you had an extra 100 bucks, what would you do with it?" Shopping spree? Two tanks of gas for a weekend getaway? "People can get very motivated to change their habits for that type of reward," she says.
9. Keep trying. "Past failure doesn't predict future success or lack thereof. There's always hope," says Liskov. There will surely be bumps along the way that buck you off the wagon, like a decadent dessert or a missed pilates class. But more important than your slipup is how quickly you recover from it.
