i've seen a 62 yr old on biggest loser lose 30lbs in a week or two, but thats when you're working out what, 6-8 hours a -day-? i've seen people on this board lose 20+lbs in their first two weeks, but thats for very overweight people and its almost all water. so its possible, but not probable.

if you only have 20lbs to lose, i seriously doubt you'd drop it in a week unless you did very, very unhealthy things to yourself. there is no magical secret that will make weight drop off overnight, so don't believe any fads that tell you so.
