By planning your meals and logging what you eat and drink, you will start memorizing how many calories are in your favorite meals and ingredients. Best of all you will learn your own eating habits and cravings, so over time you can better plan your meals to suit your cravings.

Try basing your meals and snacks off this plan and double up on veggies at any opportunity — more fruit at snack time works too! You can also add an extra ounce or two of protein at all meals if you find yourself feeling hungry. The combo of fiber from produce and lean protein makes this an adaptable strategy that’ll help you lose weight safely — one meal (and snack) at a time!
