My fast food weakness.
People who wolf down their food and eat until they feel full are three times as likely to be overweight than those who just take it slow. According to an article in the British Medical Journal, eating quickly is actually kind of addictive.
So slow down. Stop before you're stuffed. That's easier said that done when you have a typical busy evening of picking up your kid from school, going to the grocery store, then making dinner, then throwing a load of laundry in before heading back out for an evening meeting. Whew, I think as I wipe my brow, a bag of fries in hand.
Are you a speed eater?
