How to reduce calories in coffee drinks
Use a low calorie sweetener.
Replace teaspoons of sugar added directly into your coffee with a low calorie or no-calorie sweetener, such as splenda. Follow the directions on the package regarding serving size and resist the urge to add extra.
You can also request this substitution when ordering at a coffee shop. It is best to choose sweeteners that do not list " aspartame " as one of the ingredients.
