CFB nailed it. Just keep at it.
If you want to lose weight, you probably need to reduce snacking and get used to going to bed just a tick hungry. If it were me, I'd be less prone to adding HIIT and more likely to add a day or 2 of weights per week. Adding intervals will likely increase your cortisol, which will make leaning out more difficult. Lifting weights will probably add a little muscle which will raise your resting metabolism and give you a better hormone profile (lifting heavy stuff tends to increase testosterone). Also, make sure you get plenty of _good_ sleep (this a bigger deal than you think). Good luck!
