week 3 post op....

Well I am on week 3 post op. I thought i had no restriction because of how hungry i was for the first 2 weeks following surgery on liquids only, then i started mushies and seemed to be eating alot . So i decided to do what so many people are recommending on this website track calories on myfitnesspal.com well i started yesterday and it recommends i use 1500 calories yesterday and today i used less than 1000 and am about 15 grams of protein away from getting what i need. Does that sound about right? i am eating about 1-1 1/2 cups of mushie food at a time (which seems like alot) but it is filling me up for several hours.

is it possible the first couple of days after switching from liquids to mushies i was so hungry i ate more?
