No. This is a really unhealthy way to go about dieting. It's verging on anorexia. You will not be able to sustain this for a long tim, and even if you do then you can do some serious damage to yourself.

With the amount you are trying to burn off compared with how much energy you are taking in, your body is crying out for glucose and your cravings will go through the roof.

Having water be your only drink is a good idea, but eating 3 meals a day will be much better than eating just one, and much easier to maintain.

Fucking christ, east whatever you want, three square meals, run for two hours or more each day(continuously) , done.
EDIT: humans need to eat and drink, don't be stupid

Very wrong
Only 1 meal a day is not enough
Losing weight in short period of time is eaither impossible or very unhealthy

Please tell me you're joking. That isn't a healthy, logical, or even effective way to diet at all. To start with, trying to lose weight fast is a losing battle. Try instead to lose weight efficiently and healthily. Cut out unnecessary fats and oils, eat clean, drink water, get plenty of sleep, exercise for a minimum of 30 minutes per day, and work in some weights.

Don't get the famous author Voltaire wrong. He could actually mean that we should eat and drink at a reasonable level. He did not say 'live to eat' but it is 'eat to live' I presume.

I agree with lola. and your motive too is kinda Meet a physician to work on a proper diet for you
