Weight Watchers give helpful Halloween tips [1]: "Eat before going out trick-or-treating with the kids. An empty belly and a full bag of Halloween candy is a recipe for disaster. Children and adults should eat a healthy dinner, too, complete with vegetables and high fiber foods before indulging in a Halloween treat. This will help prevent the urge to splurge. After sorting through the loot and letting children pick a few small Halloween treats, hide away candy to be enjoyed gradually, over time, rather than binging on all of it in a few days."
