I struggle with this. I am 23 years old and have been drinking 2-3 cups a day since I was 17. I have a lot of extra body fat on my 5 foot 9, 163 pound frame, and I attribute most of this to not having an appetite in the morning. It is very hard for me to eat breakfast in the morning after or while drinking my coffee, so in the past I often times would simply not eat breakfast. I simply have NO appetite when I wake up and I credit a lot of it to the coffee.
Over the last 2 weeks, I've been taking in my breakfast first and a glass of water (or 2) and THEN drinking my coffee about 30 minutes after and I feel a LOT better throughout the day.
It worked for me, if you run in to any of my problems or similar ones hopefully you can try what I did.
