Here are a few of Susan Albers' mindful-eating tips:
Sit down when you're eating.
Use a plate for everything; don't just grab handfuls of snacks from bowls.
Leave evidence -- candy wrappers, empty wineglasses -- of what you've consumed in plain sight so you don't lose track.
Take time out to calm your mind, especially during stressful periods.
Store less-healthful foods where you can't easily see them; keep healthful foods such as fruit where you can see them.
