If you havent already, i highly suggest you take photos every week or 2 weeks first thing in the morning in the same place withas same lighting. your eyes can lie to you. these pics will be a way to look at your results more objectively to make the right changes to your diet and cardio.
Also micronutrients combinations do make a difference as well, but calories monitoring is more imordant. If you have no idea where to start go 33% pro, 33% carb, 33% fat in terms of calories and adjust as you make progress or hit plateau along with managing your calories.
Roll with it bro. Once you see things start to slow down as in progress. I wouldnt decrease any calories or add in anymore cardio yet, Id shift more calories in favor of protien and take the difference from carbs and fats. Just doing that you get things going again in favor of fat loss and muscle retention.
