I've been at it awhile so I'm not surprised anymore, but I too am also surprised by some of the splurges. In September I was travelling and I got these cinnamon melt things at the McDonald's at the airport, thinking they'd be around 250 calories. After I ate them I checked on my phone and they were close to 500 calories :(
These days I've been surprised at how little certain recipes I make are actually, calorie-wise. Tonight I'm making a chicken marsala pasta that involves butter and cream as a treat for my BF, and after building it in the recipe builder it's still under 600 calories for a pretty healthy sized portion (fat is on the high side at 21 grams but I don't worry much about that). I had been avoiding certain recipes because I just thought they'd be calorie-bombs (like my meal tonight) but some are actually not bad at all.
