When dieting, my family and I are restricting all kinds of stuff we eat, and drinking pretty much only water. On a diet we get really bored, and things like Diet Coke are extremely tempting. Not only does the bottle say it’s zero calories, but it also has caffeine and tastes so much more interesting than normal low-cal diet food or water. This is the appeal for us, we’re always trying to consume fewer calories and are looking for a way to have something that tastes less boring.
