Myth: Eating slowly can help you eat less food
Fact: "How fast we eat hasn't been firmly shown to affect how much we eat, and research suggests it's tough for people to maintain a slower rate of eating over several months," says Barbara Rolls, Ph.D., author of The Volumetrics Eating Plan (HarperCollins, 2007). "Although many say it can take about 15-20 minutes for you to sense that you're full, certain hormones and satiety signals take longer. Some research suggests it can take up to an hour or more for signs of fullness to peak."
The bottom line: So what's the best pace? Rolls recommends eating at a rate that maximizes enjoyment of the food.
