Increase calories?

Hi guys, this is a question for the calorie counters on this page (I know I could ask on a sub that does calorie counting but I’m afraid I’ll get judged for using mounjaro) so I’m on my second pen of 5mg and that combined with getting a really awful cold last week, I ended up barely managing to eat 800 cals a day for a few days (I know, not healthy, but honestly the nausea was so awful I was struggling to keep anything down). Anyway, I noticed I lost only 1lb this week (again I know this is a fine and dandy weight loss, but I was losing 2-2.5lbs easily for a long while there)

I was just curious, I was thinking of increasing my calories this week to 1400-1500 (from the 1300 recommended by my calorie app) and I was wondering if anyone noticed an increase in weight loss when increasing their calories slightly ?

Thanks and have a lovely Sunday!
