A calorie counter is an easy way to keep track of your daily food intake. It can help you find the number of calories in the foods you eat, as well as the total calories you've consumed and burned throughout the day.

Some tools like the Calorie Counter allow you to look up the nutritional content of certain foods. For example, if you click on "bananas," it will tell you that one medium-sized banana contains 105 calories, 14.4 grams of sugar and 27 grams of carbs.

Other more detailed online calorie trackers such as MyDietJournal, My Calorie Counter and FitWatch allow you to establish a daily food diary. After creating an account, you input everything you eat or drink throughout the day from a pre-set list and the serving size. The calorie tracker summarizes total calories, as well as total carbs, sugar, protein, salt and fat consumed each day. Some will even allow you to enter your weight-loss goal and tells you how many calories you should be consuming and how close to that limit you are after each meal.

There are also calorie trackers as part of complete weight-loss programs such as Calorie King or Weight Watchers.
