Ugh. I work out with a trainer and we are stumped. I have totally plateaued. I eat tons of protein, exercise lifting the heaviest weights I can, do interval training, take all kinds of supplements designed to boost your metabolism (CLA, green tea) get lost of sleep, pretty low carb yadda yadda yadda and I cannot get past this weight and body fat% point. Now, I am not "fat" but I am irritated that I am working so hard with no new results. Has anyone found this? Is my body hoarding calories from years of undiagnosed Celiac? I was only diagnosed 18 months ago at the age of 42 after thinking that I was going to die. I should be way more fit and muscular than I am. My other thought is that I am taking an anti depressant (that I am weaning myself off of, which is a fresh hell unto itself). It didn't cause me to gain weight, but can they screw up your metabolism? I am so frustrated.
Considering changing your workout to running only. It's the single most powerful exercise to loose weight and it worked well for me and my friends. Good luck and think positive!
