Tracking calories can get really tedious. With this skill, you can just tell Alexa to increment your daily calories by hundred calorie increments (100, 200, 300, 400, 500, etc.). You can remove calories from your daily total to account for exercise or mistakes. You can also ask Alexa to tell you your daily total so that you can monitor when you've reached your goal.
