I know you're impatient to lose it but trust me, that will only backfire. You will gain it all back and then some. Slow and steady is the only way to go. Make small changes, something you will be able to live with. Otherwise you're in for a lifetime of yo-yo weight gain/loss. If you do it slowly, then you'll only have to lose weight once. I've been where you are, and it took me years to get on track but I lost it slowly and have kept it off for 10 yrs, without depriving myself along the way.
