Hi Melissa,
Yes, I will recommend you up your calorie level, especially if you are still hungry after your meals. To change your calorie level, post your request with the tech support staff in this message board. Go to the home page of this message board and scroll down until you see their forum.
In the meantime, add ~50 more calories to each meal. If your problems continues, I will recommend you consult with your doctor; just to make sure they can rule out any other issues.
Hope you are feeling better soon :)
