Don't let yourself get hungry. Eat regularly, and when you're out running errands, shopping or traveling, be sure to pack some healthy snacks to have on-hand. Then you won't be as tempted to grab something at the mall food court, the airport fast food restaurants, or the rest stop.
Put your goals on your refrigerator, or in your smartphone or Iphone.
Before you go to a restaurant, check the menu online, and plan what you're going to eat, so you're not tempted in the moment to go overboard.
And schedule breaks for exercise, and your favorite relaxing, stress-busting activities like yoga, meditation, walking, crafting, and the arts.
