Answer :
A calorie is a unit of energy, which 1 calorie unit is the amount of energy it takes to raise the temperature of 1 gram of water. Energy is power derived from utilizing physical or chemical resources.
The label is misleading because people don’t know the actual definition of a calorie. The drink is advertising that it gives you no energy, but since people think calories are bad and unhealthy, it seems like it’s advertising that it’s healthy. Which is not true, just because something has no calories doesn’t mean the ingredients are good for you.
