Unlike drinking alcohol every day, drinking black coffee actually improves your liver. It’s been shown that people who drink four or more cups of coffee a day (24+ oz., or two “Tall” cups from Starbucks) have as much as an 80% lower rate of cirrhosis of the liver. People who drink this same amount also have as much as a 40% lower rate of developing liver cancer.
If you drink coffee, serving it black is your best option for weight loss. Black coffee is calorie-free — it's the cream and sugar that can pack on the pounds. A single cup of coffee with 2 teaspoons of sugar and an ounce of half-and-half has 69 calories. And because the average American drinks roughly 3 cups of coffee a day, that adds up to an extra 207 calories. If you were to switch from coffee with sugar and cream to black coffee every day for a year, you'd save more than 75,000 calories — the equivalent of almost 22 pounds of fat.
My mom's been a long-time lover of coffee. I can still remember her sending me up to the counter for her usual when I was a kid. “Double-tall nonfat extra hot latte with extra foam, no whip.” We lived in the coffee-loving city of Seattle before coffee was uber chic, and I like to think I inherited some of my mom's refined cafe preferences. But the fact remains that at 20-something years old, I still hadn't figured out how to make black coffee that didn't taste like mud to me. So I snooped around her kitchen when we were up to visit last weekend to see how she does it. “What's this coffee brand on your counter, mom? Gevalia?”
