At ETH Denver I was 190lbs my all-time heavy weight. I saw pictures and videos of myself and was pretty disappointed. 

Through diet and exercise I weighed in today at 170lbs. My goal weight is 160, which I think I’ll hit by the end of the year.

you got this!
how many weeks did this take?

you should hit your goal before the end of the year then.

are you documenting this? 
maybe write about the things you had to stop doing and the things you had to do more.
