I know it's a popular notion on this forum in general that cardio either isn't necessary for fat loss or that HIIT is somehow superior. My goal here is to maybe (just maybe) change your mind. Each time I find myself cutting I'm always surprised just how much easier it is when I incorporate light/moderate distance running into my routine. It doesn't take a lot of time and doesn't have to be incredibly difficult. The benefits go beyond a faster/stronger cut with a steeper calorie deficit - I find that my stamina in the gym improves along with overall energy levels throughout the day/week. If anything the 3-5 miles a run 2-3 times per week actually augment lower body resistance training I routinely do once a week as well. Screw the interval training. Screw treadmills. Screw the misinformation and irrational fears of muscle loss. Put on your sneakers and go for a jog. Outside. Satisfaction is guaranteed.
