If you drink 2 cups a day, switch from cream to whole milk. Two tablespoons of cream, an average serving in a cup of coffee, has 40 calories. Two tablespoons of whole milk has 18 calories. You save 22 calories for every cup of coffee you drink; 44 for two cups. Multiply that by 365 days in a year and you save 16,060 calories by making one simple change. Consistent small changes can add up to big results.
