i recently started this on sunday i need to lose 20 lbs fast, but with my job i really dont’ have time to do exercise, so i decided to walk to work at least 3 times a week, which is a mile each time, and after work i do 20 min pilates, i cut back on soda and junk foods, i just don’t know what else to do..i don’t want an expensive diet ..does anybody know how to lose weight fast???
