It depends on what type of caramel flavour product you go for. Our Caramel coffee contains the same calories per serving as regular coffee and with its sweet flavours, requires no additional sugar. As long as you watch how much milk you add, it's perfectly diet-friendly.
However, when syrup is used to give a caramel flavour to coffee, your drink will have higher sugar content. Therefore, like any food, these drinks should be consumed in moderation if you're on a weight loss plan. Any caramel coffee recipe such as lattes will tend to be more calorific, so should be seen as a treat, rather than go-to brew.
