Coffee is one of the world's favorite beverages. Many people can't even think of starting their day without a piping hot cup of coffee. However, a recent study says that it might be the reason for the increase in calorie level in a human body.

According to Reader's Digest, most of the people who drink coffee don't drink it "black". They tend to add sugar, milk or cream to their coffee. These "add-on" can have an adverse effect on one's health, as they are often dense in energy but low in nutritional value. If black coffee is taken in, it is not going to be a problem.

The study suggests that flavoring up one cup of coffee can lead to the intake of 69 unnecessary calories. Sugar alone accounts for 60 percent of these calories. Cream fat accounts for most of the rest of the unnecessary calories consumed. Anyone consuming multiple cups of flavored coffee every day can add on a lot of calories from these, the study says.

According to The Huffington Post, one does not necessarily need to give up his habit of having coffee to get rid of the ill effects. The best way to have the coffee is to have it "black", which means without any flavorings. Ditching the sugar, spice, cream and milk while having coffee might be very beneficial for anyone's health.

If one can't just have coffee without any of the above-mentioned flavorings, it is better to opt for healthier substitutes. Low fat cream can be a good option in place of milk, the study suggests. It also says that as time goes by, people's preferences tend to change. So, after sometimes, if one tries hard enough, it is possible to let go off having additional flavorings while having coffee.

Being one of the most popular drinks in the world, coffee is quite a hit among the people who work for late hours. The study suggests that initially, it might be problematic to avoid coffee add-ons, but for the sake of good health, one should get accustomed to it.
