I noticed the same thing yesterday, Sandi!
In our office, when there's a celebration, we usually order pizza. However, there's a great lebanese mom & pop place down the street with super healthy stuff. So, about a month ago when we were planning for this celebration, I suggested we get the food from there again. Everyone agreed. So, yesterday I ate crap almost all day and when the food came, yeah it was pretty good. But last time I we got food from there I LOVED it and thought it was amazing. Instead, I felt like I ate lard all morning... which I essentially had.
