Eat slowly! We tend to want to eat quickly when we're extremely hungry, so make sure to slow down and be mindful. Take 20 minutes to eat and focus on enjoying your bites, the colour, flavour, the aroma, and how the food makes you feel. "Before going for seconds, you can watch the clock and make sure it has been about 20 minutes since starting your meal." Leslie said. You might find you're not as hungry when you wait another five or 10 minutes.
