Well, you're overloading yourself with protein and fats, it sounds like, and nothing to offset it on the carb side. So you're getting lots of long-term energy resources but little in the way of immediate burn that comes with glucose and sugar. Then you're going the opposite on the weekends with the cake. Short term, aside from indigestion and some constipation it probably won't feel like much. However, without some serious exercise, you're probably going to pack on some pounds over a few years of that because it's not getting burnt off with energy and muscle-building otherwise. Then your digestion is taking a beating processing all that meat with little roughage and fiber to make it easier to move, so you're going to likely end up with up with a lot of hemmorhoids, lol.
