Yes, but sugar is incredibly calorie dense. A teaspoon of sugar (or about 5 grams) is about 20 calories. A 12 oz can of most soft drinks have about 40 grams. They clock about 140 calories. All from sugar. You're going to hit 2000 calories way before you feel like you've eaten anything significant if you get all of your calories from sugar.
