f/25 lost 120 lbs/// underwear pictures re: lose skin

CONGRATULATIONS AND THANK YOU so much for posting your picture! Thanks to you I feel so encouraged about the possible results I can achieve. I am 37 years old, 5' 8" and currently weigh 316 lbs. My goal is to get as close to 160 lbs. as possible. I just started my journey one week ago and have not lost any weight AND have NOT lost any hope yet. This (counting calories and being hyper-conscientious about what I eat) is absolutely new to me, but I'm ready for this challenge. I reached my breaking point (which I needed) and I am staying as close (and sometimes even under!) my daily calorie goal. I will get better about adding more exercise to my routine.

Can you please share more insights into your journey? You said that it has been less than one year since you started. What was your "breaking point", if any? What motivated you to start? Did you see results the first few weeks? Were you counting calories and exercising? I would appreciate any tips and insights from you.

First of all thank you so much and congrats on starting this, you won't believe how great you'll feel this time next year.
My breaking point wasn't really a set point in time, it gradually snuck up on me. I was putting on weight bit by bit and feeling increasingly uncomfortable.
I was a chubby kid, a fat teenager and then finally an obese adult and somewhere along the line I crossed over from 'fat but still active and happy' into 'fat and uncomfortable'. Then my ankles started hurting, I got to the point where simply walking caused me physical pain and I was barely 24 so I sat down in front of my laptop and read up on nutrition and weight loss for the first time in my life. I didn't really believe I'd make it but I wanted to try at least.
I ate around 1500 calories at first, consisting of veggies and lean meat 2 times a day and either cereal or oatmeal for breakfast. I'd always, without fail, have some kind of snack once a day (a muffin, two cookies, pudding or whatever else I felt like) as well as some fruit and 2-3 cups of coffee with skim milk and sugar. Once or twice a month I'd get a huge pizza or a doner kebap. After a while I loosened up a bit and sometimes went over my goal but in the end I always made sure to not completely eliminate my weekly deficit.
The weight melted off the first few weeks. I had a few plateaus but I never worried about them because I knew that I was honest with my logging and that the scale would eventually catch up. After reaching 200 lbs I upped my calories to slow down a bit, I was kinda scared of what I looked like in the mirror. My gut was hanging way down, my arms had freaking WINGS and my breasts were a nightmare.
Like I said in my original post though, it just needed some time to tighten up a bit. I look way better now in comparison and hope to improve further. Make sure you drink lots of water and use lotion, other than that it's all luck.
As for exercise: I did originally start with some cardio and weight machines 2-3 times a week but I quickly dropped it as I had to move away for school and work. The only exercise I got after that was walking to school and back daily (not even a mile in total) and going window shopping in town. It was all diet basically.
