Per the FDA, manufacturers are allowed to say a food is calorie-free if a serving is less than five calories. Which means that if you're squirting a lot of that "calorie-free" flavoring into your smoothie, or spraying a bunch of that "no-cal" cooking spray in your pan, you could be getting as much as 20 to 30 calories.
The best 0 calorie foods to add to the diet include green vegetables like cabbage, cucumber, broccoli, etc. Fruits like apples, watermelon, berries, and kiwi are the best to consume for healthy weight loss.
The bottom line: Aside from water, no truly calorie-free food or drinks exist. Why do so many things say they have zero calories, then? The FDA legally allows manufacturers to label anything with less than five calories as having zero calories.
