In a study published in the Journal of the American Dietetic Association in 2011, researchers in New Zealand looked at the relationship 2,500 women had between their self-reported speeds of eating and their body mass indexes. For each step up in speed (on a five-step scale from very slow to very fast), BMI increased by 2.8 percent. By slowing down, you give your mind a chance to process that your body is full. Increase your meal splits by eschewing distraction: no computer, no television, no newspaper. You’ll become aware of every bite.
