Newbie pre op with a BMI of 62

I my I am so happy to have found all  of you. I am pre-op everything complete except the weight loss. Been on the lean and green but think I will be switching to the Medifast. Weight is very slow at coming off. 414 Sw 403 Cw in three weeks. Maybe I am nuts but so many people said us "bigger" people the weight comes off quicker, well I am still waiting LOL. Has anyone felt like that or had slower weight loss pre-op obviously there isn't something I am not doing right. Any suggestions?

 Hi!! I am new too and feeling the same way! I am at 399 and really wanted to see what others were experiencing being around this weight. Nice to see that I am not alone in my thinking- or weight.
