How can I lose 20lbs by june?

What or how can I lose 20 lbs by June? I'm 5.2 and 122

I'll tell you how, I'v done it, I am 5.4 and 108 pounds, from 125. okay, here is my advice.
exercise your but off. every day walk or jogg, do push ups, and curl ups about 100 times a day. EAT HEALTHY, DO NOT DIET! the last thing you want to be is staving

sounds like a healthy weight to me, but....
run a frickin lot and eat lots of protein, so a ton of sit ups

Cold water! Your body has to raise the metabolism to warm the water before it can absorb it. Don't drink cold water if your exercising heavily, room temp. water.

without passing out? I don't think so! but we can get you in the ball park! lots of cardio and protein shakes! don't over do it or we will most definitely see you at the crossroads!
