That is called crash dieting and based on 2 years of experience when I was younger it does not work. Restricting calories to that few results only in a build up of hunger. After a few days or even a week if you have a lot of self control you will end up bingeing. This is not a theory it is a fact. Trust me, u WILL end up bingeing. Also, it's terribly unhealthy--during my personal experimentation I suffered from a substantial amount of hair loss which trust me is NOT fun and took over a year to undo the damage, and muscle loss. The best & fastest way to lose weight imo is to eat 5 small healthy meals a day, about 175-200 calories each give or take. Also drinking 3 glasses of green tea helps you burn up to an extra 300 calories & curb hunger. Carrot sticks are an excellent snack between meals because you burn off the amount of calories they are as you chew them, & apples stimulate your metabolism. Also if you choose to go with starving yourself you will be slowing down your metabolism in the long run. Your metabolism gets used to surviving on 200 calories a day and thus has to work much much harder when you eat more than that and cannot metabolize as fast. When I was in my crash dieting phase my weight would constantly go up and down by as much as ten lbs from week to week because a person cannot possibly maintain such a restrictive diet. I have followed a diet almost identical to the one I recommended and have fairly easily kept a slim figure for three years now, which is amazing considering I have a relatively slow metabolism. Everyone is constantly asking me how I stay so slim. Hope this helps.
