Noooo dont do it! u lose weight, and regain twice as much! u feel weak all the time, and look pale and ill. u cnt enjoy any nice foods, u can die from a heart attack from starving urself, and ur kidneys will fail. starving urself slows metabolism, which wen u go back to ur normal diet ( Which u will do eventually believe me) u will put on soo much weight. u lose w8 faster by eating healthy, and doing actvitys, to get u fit. good luck
