This Fizzy Apple Cider Vinegar Drink is just 7 calories and so easy to make!I recommend fresh lemon juice, the store-bought stuff is filled with preservatives which can actually hinder weight loss.Special Tip: I like to create ice cubes with 1 tablespoon lemon juice and 1 tablespoon apple cider vinegar for later. This helps meal prep the fizzy juice. Then I just add 1 ice cube to a glass and pop it in the fridge at night, it thaws and is ready for drinking by morning.
