text: how do you lose 20-30 lbs in less then 2 months? i need to know because i am going down to georgia for the 1st time to finnaly meet my biological dad whom i have never met before and i want to look good. help me! this is no joke either! never met him or knew who he was untill about 3 weeks ago.  im 18 now~! lose the weight for yourself not to just look good when you meet your father for the first time.  start by changing your eating habits.  then drink plenty of water and coffee and tea aren't one of them.  then you should start and exercise program maybe even just walking 3 or 4 times a week. and if you really want to lose that weight limit the evening eating say no eating after 6 or 6:30pm  good luck with your weight loss.
