The human body is not made to lose that much weight in one month.

just do this

multiply your weight by 12
then subtract 500
that's the amount of calories you would have to eat to lose 1 lb. a week
then burn off another 500 calories by exercising and you will lose 2 lbs. a week

which is healthy weight loss
it would be very hard to lose 15 to 20 pounds a month(and also not so healthy)
and keeping it off would be hard to
