How many pounds do you loose if you eat 500-600 calories a day and still exercising?

WOW! This would be safe if you sit on the couch all day literally. If you go without food your body stores fat not knowing when the next time it will be fed, then when you do go back up to your norm you will just get fatter, Stop being lazy and do it the right way, CARDIO!

You may get instant gratification doing this but the long term effects you will pay for the rest of your life. You will probably always go back to this method thinking "it worked that one time" but the weight will just keep stacking.

It can be very bad. And in the end you will gain weight. When you starve yourself for any period of time your body will begin to feed on the fat (leading to weight loss) But it will only feed on a little bit of your fat before it moves onto your protein from your bones and blood stream.

Which can be very dangerous and cause you to be very ill. You will loose weight, but more then likely end up in the hospital. After the 17 days are up and you begin to eat regularly again, even if you slowly go back up in calories you will gain weight.

Your body will still be in servival mode and will turn anything you eat into fat-- because it thinks it will need it later.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
