Stuck at 208-212lb for the last 3 months.

I’m a male 6 feet tall and 37 years old. Before I started my weight loss journey last year in October I was 260lb. Today I’m at 210lb. My weight has been the same for the past 3 months. I stepped up my cardio to HITT sprints on the treadmill 4x a week. Is it my diet that’s lacking here to get under 200lb? My goal is 195lb and my stretch goal is 185lb.
