Fast and effective way to lose weight (your personal expierience)?

I want to lose weight before summer is over ive tried the tracy anderson method but it was too hard I need to lose more weight before I go into that. Ive heard of hoola hooping and the 17 day diet I dont know what to do I wanna do it without pills and surgery. right now im looking for a fast and effective diet I want to lose 40-50 lbs before I start the tracy anderson method. If you know any cleanses that dont taste like poo and how much weight you can lose please let me know. I hava a 2yr old and just gave birth to a 6 month old and this weight has got to go this is the biggest ive ever been im 5'10 and 200 lbs. my body is a small frame so it looks bigger than it sounds.
