Oatmeal: Fast, easy and filling, high fiber keeps you feeling satiated and helps maintain healthy cholesterol levels. Raisins, cranberries, nuts, or cinnamon add interest to plain oatmeal without the calories of sugar. No time for old-fashioned rolled oats? Sacrifice a little fiber and opt for instant alternatives to save time.

Popcorn: Pop your own corn from shiny golden kernels for a low-calorie, high-fiber snack. Not only does fibrous popcorn keep you feeling full and satisfied but at just 30 calories per 1 cup serving you can eat a lot without feeling guilty. Skip the butter and just toss lightly with a little sea salt. Make your own grown-up gourmet popcorn by mixing in your favorite fresh herbs or splurge by mixing in two tablespoons of parmesan cheese.

Canned Tomatoes: Fresh packed, canned tomatoes are a surprisingly vibrant pantry staple. Choose a variety without added salt to keep the sodium in check. Fat free and full of antioxidants, canned tomatoes pack a flavorful punch. Just heat and enjoy with a little black pepper or use them to transform your favorite dishes.
