Adding extra sugar or cream to coffee is more likely to do harm than good. That's why many people are leaning towards sugar-free or black coffee.

For many, the start of the morning is incomplete without coffee. Some people find a way to get energized in a cup of coffee during breaks or when they're tired. But if there's no sugar in that coffee, what are the benefits? Experts say that drinking coffee without sugar is not just a taste habit, but it can be a smart decision for health.

Drinking coffee in moderation helps increase mental alertness and reduce the risk of various long-term diseases. However, adding extra sugar or cream to coffee is more likely to do harm than good. That's why many people are leaning towards sugar-free or black coffee. Now let's find out why sugar-free coffee is good for you.

1. Helps increase metabolism
The caffeine in sugar-free coffee activates the body's metabolism. It increases the thermogenesis process, which allows the body to burn more calories. Black coffee can be helpful if you want to control your weight.

2. Improves focus and concentration
Caffeine reduces the activity of a chemical called adenosine in the brain, which causes drowsiness. At the same time, it increases dopamine and norepinephrine, improving attention, alertness, and thinking ability.

3. Rich in antioxidants
Coffee contains powerful antioxidants, including chlorogenic acid, which work against harmful free radicals in the body. The effectiveness of these ingredients is better found in coffee without sugar.
