You kinda are, but you could possibly improve the results by have no calories (CO and cream in coffee)
until that 9 am point and then eat a whole food meal at 11-12 or at least when your hungry.
That thing you really want to avoid is long steady state cardio.
Walking in general is great all the time, but I wouldn't do it if you hate it so no need to force it.
Doing HIIT is good, but try to do it within the first 3 days after carb night.
I do the following day and again on the third day doing 1:30 sprint 3:30 active rest for 5 rounds
the following day, and then do 0:45 sprint 4 minute active rest 5-6 rounds on the third day.
Also, resistance training is great, just don't do high volume.
Go heavy, get in and get out quick. Most of the time I spend 40-45 minutes including warm-up and cool-down.
