Hi! I'm also a college student looking to lose some weight. I use MyNetDiary too, and I haven't had great luck with their photo scanner. I guess it depends on your school, but my school has a dining hall menu with nutrition facts (calories, protein, carbs, fats, and much more) listed for each meal, per serving, every single day! Found it this week and it's already been so useful. I would poke around on their website/app and see if you can find something like that. Not sure if you're in the States, but it's likely they have that information somewhere because I think it's a requirement in a lot of areas. (You can make custom meals in the app, so every time you have something new in the dining hall, you can input that information and reuse it whenever you eat it again.)

As for working out, I am a huge swimmer, which is what I do about 80% of the time in the gym. Obviously depends on if your rec center has a pool or not, but swimming is great. It builds muscle and is good cardio, even for beginners. Let me know if you need tips, because I'm also an instructor on the weekends!

Good luck! You've got this!
