Don't rush through the very best part of eating: tasting the flavors and enjoying the textures. It may sound simple, but chewing your food slowly and savoring every bite also helps you eat less. Many of us take just 10 minutes or less to wolf down a meal. It takes about 20 minutes for your brain to receive signals from your digestive system that it's full, so when you eat quickly, you tend to eat more because the brain doesn't get the message until after you've stuffed yourself. Plus, chewing thoroughly will help aid digestion -- which begins in your mouth. Chewing breaks the food into smaller particles and mixes the food with saliva that contains digestive enzymes.
