Track what you eat so you can be sure you are in a calorie deficit. Don't overestimate the energy consumption of exercise.

If you aren't losing weight, that means your energy balance (calories in/calories out) isn't in a deficit. Either because you are eating more than you think or you are overestimating the calorie level you need to be at. Fancy diets, fads, etc are way less important than energy balance and exercise. Also, as you cut, your metabolism will adjust and you will either need to exercise more or eat less to continue the progress.

I've gone from 29% BF to 8% with heaving lifting and managing intake carefully. I've maintained it for many months with ease but mainly because I'm committed to training (heavy weights) and track everything going in my mouth. I've also played with my macros to get it right... measuring BF and weight and comparing it to my intake and adjust until I found MY actual maintenance level (cutting/bulking from there). I've found that I cut well around 2,100 - 2,200 calories and maintain well around 2,650 - 2700 calories per day. I'm also 5'10 and around 172 lbs.
