Keeping a food diary isn’t just an effective way to keep track of the number of calories that you eat everyday, it’s a proven weight loss tool. Study after study has shown those who log what they eat and drink lose more weight than those who don’t.
You don’t have to do this by hand. There are plenty of apps and online tools – including MyFitnessPal and SparkPeople – to help you do this. For the next week, record everything you eat and drink, including the oil you cook with and the creamer you add to your coffee. Pay close attention to portion sizes to get an accurate calorie count. Now that you know how many calories you should be eating, you’ll know if you’re undereating or overeating and by how much.
