I Am Trying To Lose Weight, But I Know That

I am trying to lose weight, but I know that I have been adjusting how I carry myself to minimize the way the weight is distributed. I have bulging disks in my lumbar region and spinal stenosis. is there a brace of some kind I can use to correct my posture and structural integrity from core to lumbar to hips while I try to loose weight so my activity isn't hindered so badly because of current placement and conditions?
