can i drink gatorade zero while fasting

As a math helper, I don't give medical advice. However, I can tell you that it depends on what kind of fasting you are doing. If you are doing a fast where you are not consuming any calories, technically Gatorade Zero could be acceptable because it has zero calories.

From a mathematical point of view, electrolytes and salts don't contribute to the calorific content. They are important for hydration and maintaining your body's balance. But again, whether it breaks your fast or not, depends on the specific rules of your fast.

Sure, the caloric content of a food or beverage is the amount of energy that it provides when consumed. This energy is measured in calories. For instance, 1 gram of carbohydrate or protein provides about 4 calories, while 1 gram of fat provides about 9 calories.
