Measures caloric intake to maintain desired weight

Lose It! tracks exactly how many calories a person consumes each day, and advises on how much exercise is required to maintain or lose weight. With the holiday season approaching, this 99-cent iPhone application will have us think twice about pouring that second cup of eggnog (360 calories). For our New Years resolutions, elliptical training is a good option (burns about 500 calories per hour).
