So, over the past months I've noticed the scale going up and up, but when I looked in the mirror, I felt like I looked the same. That is, until I saw myself in a picture a few days ago. As it turns out, I've gained about 20 lbs over the past year. I want to try to lose the weight, and for some reason, it doesn't seem like a lot to me. When I tell my friends and family, they seem to think that 20 lbs is a lot. Is it reasonalbe to think that I can lose this weight fairly easily?
