Elastic waist bands and big shirts are comfy, but they cover up your body and allow you to forget what you look like or what your weight loss goals are. They also encourage lounging around on the couch for hours. So when you get home from work and want to slip out of your business attire, opt for clothes that are slightly fitted. I'm not saying they have to be skin tight. They can still be comfortable, but not slouchy. Fitted shirts and pants made out of cotton or some other flexible material will give you a sense of your body image so you're not hiding behind your clothes. They may also inspire you to do something active.
