I want to lose 20lbs fast.?!

No one food is the answer you must have a balanced diet.

I have written an article for ezine articles which will be published in a few days so run a search for Sacred Heart Memorial Hospital Diet on Tuesday or Wednesday. You will lose 17 pounds in 7 days, after that it is up to you.
Always seek medical advice before going on a diet.

The only web site I've found that seems to understand this type of problem is old crow ink. You might want to try them out and see if one of their solutions works for you. There is no single program which works for everybody, all the time. Crash diets, pills, over-the-top exercise programs might work once but not for the long term. Try something that's a lifetime plan.
Hope you do OK.

This is going to suck but, you have to eat your weight in protein. That along with exercise allows you to lose tons of weight. But no fatty things, just proteins. Also take a multi-vitamin, fish oil, and drink water to make up for all the supplements you need but won't eat.

If you are looking for fast diet program, you can use my program. I lost 12 pounds in 2 weeks. If you are really serious about diet you should have a look this program. It is fast if you know right information to do diet. You can get more information at link below.
