Caffeine Calories: What You Need to Know
What is Caffeine?
Caffeine is a central nervous system stimulant that is found in coffee, tea, energy drinks, and other beverages. It is the most widely consumed psychoactive drug in the world. Caffeine works by blocking the effects of adenosine, a neurotransmitter that promotes sleep. This blocking effect can lead to increased alertness, energy, and focus.
Caffeine is also a diuretic, which means that it can increase the production of urine. This can lead to dehydration if you do not drink enough fluids.
How Many Calories Are in Caffeine?
Caffeine itself does not contain any calories. However, the beverages that contain caffeine often do. For example, a 12-ounce cup of coffee contains about 2 calories, while a 12-ounce can of energy drink contains about 110 calories.
Does Caffeine Burn Calories?
There is some evidence that caffeine may help you burn calories. One study found that people who consumed caffeine before exercise burned more fat than those who did not consume caffeine. However, the amount of calories burned was small, and it is not clear whether caffeine would have the same effect in people who are not exercising.
Is Caffeine Good or Bad for Weight Loss?
The effects of caffeine on weight loss are complex and depend on a number of factors, including your individual metabolism and how much caffeine you consume. Some studies have shown that caffeine may help you lose weight, while other studies have shown no effect.
If you are looking to lose weight, it is important to talk to your doctor about whether caffeine is right for you.
Conclusion
Caffeine is a widely consumed stimulant that can have a number of effects on the body, including increased alertness, energy, and focus. However, it is important to be aware of the potential risks associated with caffeine consumption, including dehydration and anxiety. If you are concerned about the effects of caffeine, talk to your doctor.
