Agree with Renton. There are no "bad" and "good" foods, you can have everything in moderation and be completely fine. If having an icecream once in a while makes you go on a binging bender though perhaps it's not the best idea. You've got to find what works for you.
Also <3 diet soda's, best thing ever imo. Love me some aspartame
For cooking oils I just assume nothing evaporates and just log 100% of it in my calories. I've never used cooking spray so wouldn't know about that.
Good luck. First day log looks fine
