How To Lose Weight: 22 Pounds In 24 Hours
This is exactly what Tim Ferris, author of The 4-Hour Workweek: Escape 9-5, Live Anywhere And Join The New Rich (great book btw), did when he competed in the Sanshou (an eclectic form of kung fu) national championship in 1999.
When arriving on the site he weighed 187 lbs and wanted to lose weight so he could compete in the 165-lb weight class. He lost 22 lbs (about 10kg) in 20 hours by severely dehydrating himself (80% of you is water).
To achieve this, he combined:
- Temperature treatments (very hot baths) to lose water through the skin.
- Using diuretics (dandelion root and caffeine) to lose water through urination
After the weigh-in, he gained 28 lbs (about 12kg) by rapid hydration so he would be in optimal condition to compete.
Needless to say this is not healthy and in fact very dangerous (some athletes die doing this). These techniques don’t make you lose fat, only water and are only useful for competition sports. Don’t try this at home!

Wow. yes that does seem like a very dangerous if not incredibly dangerous way to do something about your weight.
lemon juice in morning with honey is good to reduce weight also.

This kind of weight loss is definitely unhealthy. If you want to lose weight and belly fat for real you should add whole foods to your diet and eliminate processed foods.
goodness!!!! what an unhealthy way to lose weight! exercise and eat right.
i hope no one decides to go try this out to lose weight!
In college I was really slim but after giving birth to my first child, Emma, I started gaining weight. I was really sad but I managed to actually lose weight and I’m sharing my story at http://hubpages.com/hub/Ways-To-Lose-Weight-Now if anyone wants to read.
Have a good day

GENIUS!!!!! I’m SO going to try that!!
I used to rapidly dehydrate for wrestling weigh-ins. I would not recommend this for any sort of purposeful mid or long term weight loss.
omg…. im studying to be a nurse. and fyi YOU NEED THAT 80% OF WATER IN YOUR BODY TO LIVE!!!! this diet will make you very sick!!!! and very unhealthy and its a temporary fix!!! you arnt loosing fat. your sucking water from your muscles and organs. not a good idea. you can collapse your lung by doing this!!! a woman will loose wieght mostly from her face, chest, muscles and skin from doing this making her look saggy and oily. a man will loose it from his chest back and hips making him look deformed and very disproportionate… please who ever reads this dont do this. <3
