how much do you loose wieght in a month?

I lost 13 lbs on the medifast diet; no i'm not representing them; i would like to go back on the diet again; because from my experience it really does work! But it's too expensive; so i'm saving up for at least a month's supply because in that month; you'll lose like 25 lbs! So if i can lose that much weight again; i'll be so motivated; plus, my son is out out school so we have all this free time this summer! so i'm excited; so like today; we're gonna goto the park; pretty much all day; whatever I need to do to keep myself out of the house and away from the kitchen. losing weight is a very hard thing but I know there is a math too, it's all science really.

i think the most i lost in one month was 20lbs or close enough too it.. which is way too much to loose in a month.. I wasn't trying to loose that much in a month though it just happened.. once I lost a lot of weight I pretty much stayed at losing 10lbs a month. I walk daily and eat right work out and do yoga and stuff..
