RESEARCH: 5 Proven Ways Coffee Can Improve Your Health

As a huge coffee drinker, I can understand many of these conclusions. Drinking black coffee (don't add sugar or cream) after a meal really does help digestion, I can attest to that. Coupled with daily exercise and not overeating helps keep weight off. Thanks to my friend Jacquie a fellow coffee drinker, for sharing. Here's the story.  

5 Proven Ways Coffee Can Improve Your Health 

By Team Verywell Health,  September 30, 2025  (Medically reviewed by Leigh Weddle, PharmD)

Coffee isn’t just a morning pick-me-up; it’s linked to surprising health benefits beyond energy. From boosting sexual health to supporting your gut and aiding weight loss, your daily cup of coffee may do more for you than you think.

1. It May Help You Live Longer 

Drinking coffee may be key to adding years to your life. Research shows that consuming one to three cups of black caffeinated coffee daily may lower your risk of death and cardiovascular disease. 

  • The study found a 16% lower risk of all-cause mortality and death from cardiovascular disease for participants who drank at least one cup of caffeinated coffee a day, and two to three cups reduced the risk by 17%. However, adding some sugar and milk or cream cancels out these benefits, with the study finding a 14% lower risk of death. 

This study had limitations and should be considered suggestive rather than conclusive.

2. It May Support Your Gut 

  • Coffee may support the gut microbiome (the community of microbes in the gut). People who drink coffee (regular and decaf) had higher levels of Lawsonibacter asaccharolyticus, a gut bacterium linked to increased levels of quinic acid. This antioxidant can help lower oxidative stress and inflammation.
  • The polyphenols in coffee may provide a prebiotic effect by promoting the growth of good gut bacteria. These plant compounds can help improve digestion. A diverse gut microbiome is also associated with regular bowel movements.

3. It May Help You Lose Weight 

Drinking coffee alone won't lead to weight loss. However, coffee may help improve your metabolism by:

  • Burning more calories: After drinking coffee, your metabolic rate increases by 5% to 20% for about three hours.
  •  Increasing fat breakdown: Coffee significantly improved fat breakdown in the body, particularly in individuals with leaner body weight compared to those with obesity.
  • Reducing appetite: Drinking coffee before a meal may reduce the calories consumed by about 20% for men, but not for women.  

4. It May Reduce Your Chronic Disease Risk 

Drinking coffee regularly may protect your heart and lower your risk of chronic diseases. Some conditions coffee may benefit include:

  • Parkinson's disease 
  • Lower risk of type 2 diabetes
  • Liver cancer
  • Colon cancer
  • Stroke
  • Heart failure 

5. It May Boost Your Sexual Health 

  • Increasing testosterone levels: Research shows that consuming caffeine before a workout boosts testosterone levels temporarily after exercise. 
  • Improving sexual stamina: Drinking a cup of coffee 45 minutes before sex may increase sexual stamina.
