Not really. Zero calories means less than 5 calories. In fact, it is
often 4 calories, so if you were to use a lot of Equal artificial
sweetner listed as zero calories, you are actually getting 4 calories
per packet. Companies put a lot of thought into what they call a
serving size, and how they package their products for this very
reason. Given a choice between 4 calories and zero calories in a
product, people watching their weight would most likely choose the
zero calorie. Even products like spray oil, which is mostly fat is
often listed as zero calories per serving, but a serving size is very,
very small. dkw
