This would be difficult to achieve in such a short timespan, and it would also be dangerous. It is unhealthy - and potentially dangerous - to lose more than 2-3 pounds per week.
So far I lost 11 lbs
A stone is 14 pounds. So 11 stone minus 4 pounds is 10 stone and 10 pounds.
run fast
11 stone and 4 pounds. Or 11 and a quarter stone if you like. There are 14lb in a stone.
11 stone 4 pounds = 71.7 kilograms.

You don't do it that quickly.

You cannot lose 18 lbs. naturally in 4 days, it is just not healthy. The only way that one could lose this amount of weight would be through surgery.
to be honest you shouldn't starve yourself. you need the nutrients which food provides, no food = your organs eventually refusing to work because they have no fuel.
You can loss 18lb in 4 days by eating right and exericising more. It help to lose 18lb with a friend it gives you more endurance
