ok kid, here is the trick if u want to do it healthy (personally i wasnt much for the healthy way of cutting anyways).

monday-wednesday u need to eat more often than not. Have small handful meals. Maybe half a sandich(wheat and turkey and nothing else) and half an apple, banana or granola bar. Have about 6-8 of these "meals". Eat them in 2-3 hr intervals. U will speed up ur metabolism and lose weight and still be decently full. Also try to eat low sodium. At these meals and throughout the day drink lots of water. Drinking a lot of water from mon-wed will trick ur body into thinking its going to have lots of fluids on thurs and friday. So come thurs and friday u will need to cut back on water, but ur body will still be pissing and sweating a lot. Thus u will be purging water weight easily from ur body. U will need to cut it back on the food because just teh sheer weight of eating 6-8 meals might be too much to make ur weight. Thurs and fridays u will need to cut it to 1-2 tiny meals. then just run and work ur *** off in practice and u should be good.
