Is this for real? I've been keeping track of my own calorie intake for months and my highest record for total calories consumed in one day was 2670. I can't imagine what it is like to eat that many calories on top of something else.
I've looked it up and it says 1440 calories for this particular shake. I think they removed the cream top and the crumbled cookies, judging from photos, and I guess they may have added water or something to cut down that many cals.
