Anyone else have/had rapid weight loss during intern year?

^ I’ve lost like 12ish lbs depending on the day and time that I couldn’t really afford to lose. I eat 3 decent meals, I probably need to try snacking more but I’ve roughly counted and I feel like I’m eating at least 2k calories a day. I know I’ve got tons of reasons to be losing weight, and I’m honestly trying to gain more but it’s like I can’t keep up with how hard I’m working... Jw if anyone experienced anything similar and if so if anything worked for them? Ty
