Coffee has been a controversial issue in the low carb world for years, here are the facts;
Good old caffeinated black coffee is zero carb, if you want to sweeten it add FAT TO SKINNY Zero, if you want cream use heavy whipping cream it doesn't take much.
OK so what's the issue???
The issue is caffeine and it's effect on blood sugar. Past studies (which are now in question) show that caffeine can actually drop blood sugar increasing a person cravings and tendency to overeat. I count caffeinated coffee as 1 carb to keep the quantity in check. On the other hand I count decaf as a zero.
In your personal case you'll need to judge how caffeine affects your body. After a few cups of caffeinated coffee do you get hungry? If so, try a cup or two less or switch to decaf for that day and re-test yourself.
I love coffee and drink 2 mugs of caffeinated every morning and 1 mug of decaf at night.
