First off. That is impressive. Congrats.
Try pulling back on the stick of you training. Lower intensity/volume for a week or so. Cortisol can get screwed up by overtraining which makes your body hang onto water and fat for dear life.
Or just take a week or two off and replace your weight/cardio with foam rolling, stretching and very light activity.
Then pick it back up when your CNS resets itself.
