Well 165pounds woul still make you healthy according to the BMI so don't worry about what your family are saying on that front.
However, you will struggle to lose that much weight in that amount of time. In fact, you will really, really struggle.
Is it not possible for you to set yourself a more realistic target and then explain the situation to the college, so that they are clear you WILL lose the weight, it's just that losing that much in the time frame you had isn't possible?
I agree that losing that much weight in such a short time would be very difficult, at best; and not very healthy.
I realize that you are exercising a lot; what about calorie intake? Are there ways you might be able to cut back there? Like drinking more water, eating plenty of veggies, low fat, lean protein, etc. Just don't cut your calories by too much or you won't get enough.
no. i just need to loose enough weight to get my jumps higher. everything else is ok. it's just they'd like me to be at most 165lbs. but for me everyone in my family thinks that it's to skinny. i'm 5'11. If i delay college any longer i'm not likely to go back. i'm 20 and have already been to college once when i was 17. But i didn't like the career i had chosen to get a degree in.
To be honest it would be very difficult, and unsafe, for you to lose that amount of weight in that time.
Are you not able to defer the audition for a year and lose the weight safely?
Also, if you did lose that weight in that amount of time it would be very difficult for you to keep it off and you don't want to be struggling like that forever.
