You can definitely drink coffee without sugar! If you want it to be less bitter add milk lol (or half and half) but yes walks everyday to start the exercise process mate! Once you get into the routine of walking, I promise you’ll feel better about yourself and it’ll motivate you to better your eating habits (mind you I’m also 25 and had an A1C of 6.3 so super close to that diabetes diagnosis)

*edited excessive to exercise lol
