For one week, write down everything you eat and drink, good or bad. Keep track of when you eat and how much. Then take a look at your journal and see if anything stands out as unhealthy. For instance: Do you skip breakfast, only to find you overdo it at lunch or reach for high-calorie foods in the afternoon? Do you snack even when you’re not hungry? Do you eat dessert with every meal? Do you grab an unhealthy snack from the vending machine every morning with your coffee? Do you reach for unhealthy snacks when you watch TV?
