how to lose 10 pounds in 5 days

It is possible to drop 10 lbs in 5 days, but most of that will be water weight (7-8 lbs) with only a small amount being fat (2-3 lbs)

One danger in losing weight quickly is losing muscle. This means that your metabolism may slow down, you will look flabby and you won't be attracting the girls. Why don't you start doing some consistent strenuous exercise so  you build muscle and lose weight at the same time. The results will be much better. Also if you go on a strict diet, you will feel faint and your brain won't work too well. Failing school is not a good way to attract girls either.
