You could be asking how to lose 5 kg in 2 weeks, or you could be asking why have you lost 5 kg in 2 wks.

If you are asking how to lose 5 kg in 2 weeks, the answer is that this is highly inadvisable. The optimal weight loss speed is 1 kg per week. Losing faster than this may be unhealthful.

The way to lose weight is to eat less calories. One kg equals about 7700 calories. So to lose one kg in a week, you need to eat 7700/7 = 1100 calories less per day than you're currently eating.

To lose 5 kg in 2 weeks, you would have to eat 7700 x 5 = 38,500 calories less than you're currently eating in a 2-week period, which is 38,500/14 = 2750 calories less per day than you're currently eating. Let's say you're currently eating 3000 calories per day. In this case, you'd have to reduce your daily intake from 3000 calories to 250 calories! This would not be a healthful lifestyle change, because it's too drastic.
If you are asking because you have lost 5 kg in 2 weeks, then the answer is that you need to see your doctor. There are many reasons for unexpected weight loss. Some of them are serious.
