There's something we professional nutritional advisors refer to as calorie overload. Rather than give tedious explanations I will draw it out. - Sausage: approx. 324 kcal, presumably you had four - Mash potato: 197 kcal, a full serving - Peas: approx 87 kcal, a full serving - Gravy: presumably you bathed the entire plate: 163 kcal This equals 771 kcal. The average BMR: 1860 calories, this is the amount of calories you burn simply from lying in bed all day - so, a third of that, plus the following. You probably burned 10kcal day walking, 20 kcal other activities (such as breathing), 1 kcal typing things on the computer, And 50 kcal preparing your sausage mash peas and gravy. This equals 81.62 kcal, and I'll generously throw in .38 of a calorie for pressing buttons on the TV remote. 771 kcal intake VS. 82 kcal burned. This is calorie overload, without taking into account other meals you may have had. I highly recommend you avoid sausage mash peas and gravy in the future.
