Stop in for a cup of coffee

That's awesome.. and carbs are key... i went keto (almost no carbs or sugar at all) a few years ago and dropped 50# in like 3 months.. and felt amazing.. i had to stop though i went from 205 to 150# and looked like a skeleton.. felt great though :)
I need to try that. How do you count carbs? Did you find a chart or a list?
