<human>: Can you give me the gist of the text in a nutshell?

I am currently down about 45-50 pounds through diet and exercise in about 4-5 months. I cut out most carbs and processed foods (keto-ish. HFLC I guess is more accurate, 20-50g carbs daily), and I now walk about 3-5 miles a day as well as doing some light strength training 2-3 days a week. 

So far I'm happy with my progress, but I recently got back on Adderall XR for my ADHD and it makes me want to not eat....ever. I can tell when I'm hungry but I just have no desire to actually consume food. I do force myself to eat daily, but I think most days I eat 1200 calories or less. 

I started at 372ish and am now in the 320's, so it's still working, but is it okay to eat so little? I don't know the exact numbers, but I think even for weight loss, I could technically eat 2000 or even more a day if I stay active. It literally makes me sick to eat any more than I already do, though
.
I guess the real question is, given the amount of excess weight I have, is it okay for me to create deficits of this size, or should I try to find some way to boost my caloric intake?

I mentioned this to my psychiatrist when adjusting my medication and she basically said, try your best to eat more, but it's not of any real concern until you start wasting away and we don't need to worry about that anytime soon. I really need to be on the medication to function the way I'd like to, so stopping it isn't a viable option at the moment for me.
<bot>: I'm fat but I don't want to eat very much. At what point does this become unhealthy and/or hinder my progress?
