<human>: hey r/loseit

i don't usually post on reddit, so i don't know what i'm doing or even if this is the right subreddit. i think it is, but if it's not, sorry mods.

anyways, i've decided this year that i want to lose some weight and become more fit. my body has been a large part of my insecurities.

i've been involved in marching band this year (still in HS). when i started, i was at 185 and I believe I'm down to ~170ish. 

However, I'm not sure where to go from here. I don't know how much more weight I need to lose, so I guess that's what I'm asking. What weight should I put my goal at? 

And before it's asked, weightloss is more important to me right now, muscle I think can be added easier.

Can you condense the text into a few key points?
<bot>: what should be my goal weight? I've been overweight mostly my entire life so I don't know where I should aim.
