Sorry to barge in, I'm not quite a 30-something. Close though!
I love coffee. I've never been one to have it fancy, just some milk or half and half, one sugar and done. I have 2 cups a morning, maybe 3. At first I thought maybe I should try to cut back or use sweeteners (which give me the runs, sorry!), but when I did the math I'm only using about 50 calories on my coffee each day, and for the enjoyment I get out of it, 50 calories is worth it.
I honestly wouldn't worry about it unless you are going nuts with the cream and sugar. Just include it in your daily intake! It's worked fine for me for the last 50+ pounds
