1. Pick up a pen
Mindlessly munching on a bag of chips could result in easily polishing off the whole thing; write down how much you’ve eaten and you’re more likely to practice portion control and lose weight fast. Keeping a food log helps control extra calories in two ways: the combination of plain old reality check (I just ate 30 minutes ago!) and awareness that what you’re putting in your mouth will soon be recorded for posterity. In a recent study, people who kept a food journal lost twice as much weight as those who didn’t. When they combined it with a moderate diet and exercise plan, they lost an average of 13 pounds in 6 months. Journaling also gives you insight on your eating habits, says Dr. Lutes. Do you skip meals? Eat the same during the week as on the weekend? Binge when you’re feeling stressed? “Knowing your routine helps you figure out what changes are right for you,” she adds.
