how much should I eat to gain a lb in a week?

AMR • on a weight gaining and yoga journey... one day we will be a family of four 🙏🌈

I have been sick for 2 weeks. I am recovering from an eating disorder. I was on track to exceed my goal for my weigh in, but now I just want to at least reach it or be close! I was 104, then up to 108, and I needed to weigh at least 109 by Dec 5th. well, now I'm down to 106.8. couldn't have gotten sick at a worse time haha. ughhhh
