<human>: Hey, /r/loseit,

I don't think I've posted here before (long-time lurker), but I'm so excited about a recent development of mine that I had to share. Over the past year, I lost 40 lbs, but over the last couple months, I gained about half of that back due to me not being able to handle my stress without eating more than I should.

This is my first summer away from home, as I decided to work for my university instead of returning to my hometown to spend the next few months with my family. My job doesn't require much, and it pays minimum wage but includes free housing until school starts up again.

Well, I didn't get as many hours right off the bat as I'd been promised, so my first paycheck was a lot smaller than I was planning for. As a result, I didn't have as much money to spend on food as I'd thought I would, so I needed to get more thrifty: more PB&J, fruit and canned tuna; less takeout and junk food.

This past week I ate mostly PB&J, apples, popcorn, canned tuna/chicken and ramen. I also drank a lot more water than usual, avoided junk food and eliminated alcohol completely. I also continued to exercise 5 days of the 7 and made sure to take my multivitamins and supplements.

When I got on the scale this morning, I was shocked to see that I had lost 12.8 lbs! I know a good portion of that was water weight that I had re-gained since falling off the bandwagon, but that doesn't make me any less excited to see some real progress. I have been obese for years now, and I'm really trying hard to break the threshold back into "overweight," somewhere I probably haven't been since 8th grade.

I still have a long path ahead of me, but this is the most encouraged I've felt in a long time, and I look forward to continuing my journey to being healthy!

Summarize the given text in a few sentences.
<bot>: Smaller paycheck than expected led me to eliminate junk food and alcohol for a week – in favor of PB&J, fruit and canned tuna – and I lost 12.8 lbs!
