Have you ever consumed anything larger than your own head?
To qualify:
It must be reasonable to describe it as a single item in its own right (‘meal’ is not an item - it’s a collection. ‘Giant Burger’ is an item)
No liquids or semisolids
We’ll assume you have a really big head, so the item must be >5.5kg(12 pounds). High volume lightweight foods don’t qualify.
You ate it over a period of 6 hours or less.
I stick with B. Kliban’s advice on this matter.
Would something like a watermelon count? Although I don’t think I’ve ever eaten a whole watermelon all by myself.
Mostly I came here to comment on the username/thread title combination.
No!
That’s like three days of food for me.
Oh yes, easily. Tiramisu. Around here you get it in large cakes, and yes, I have eaten the whole thing in one afternoon. 
But um…yeah. That’s tiramisu, about as light and fluffy a thing you can get. 
Negative here as well.
I made myself a whole chicken with stuffing/sides/etc, but ate that over a period of several days. In a single sitting, it would probably have been a 24oz Porterhouse smothered with mushrooms and onions.
Watermelon counts (probably the easiest win, but valid)
Tiramisu only counts if you ate 12 pounds of it
I’m pretty confident I could eat a watermelon the size of my head (edible parts only - no rind or seeds) in a six hour period but I’ve never actually tried the experiment.
I used to know a guy who worked in a bakery. He was huge and he loved fresh bread. I watched him eat an entire loaf of fresh bread (with butter) out of the oven. Would that count?
I’ve definitely eaten half of a huge watermelon so it was probably close to the size of my head. My cousin and I used to cut them in half and sit with a spoon to eat while talking. High on my list of favorite summertime activities.
I haven’t, but my great-grandmother Laura would get these attacks of fruitiness when she was pregnant. Back then, oranges were sold by tens, a group of ten tens being a “gruesa”, a big one: while pregnant with my grandfather, she once bought a gruesa of oranges and ate 99 of them - another time, she ate a whole watermelon which if I’m not missing my unit conversion between Aragonese and Imperial units was on the 18lb range.
There are times when I wish I could eat something like that, but then there’s that voice at the back of my head that says that’s wrong and society will shun you forever if you eat a bowl of Red Lobster Shrimp Alfredo the size of your head..
When I was a binge eater, this was a daily thing for me. Things I can remember eating in one sitting include an entire large cheese pizza, a huge bowl of popcorn, a gallon of ice cream, many, many cookies, and god knows what else.
There was one taco salad in a huge flour tortilla bowl, with mucho lettuce, and yes, it was wider than my head, and almost as tall. Yes, I ate it all.
Let’s move this discussion of the finer points of gourmet eating to Cafe Society. From IMHO.
No, because nothing larger than my head could fit in my stomach if eaten in one sitting.
When I was a kid a hefty serving of cotton candy might have qualified.
Well, cotton candy, but not hardly 12 pounds of it. So I think no.
Oh, didn’t notice the weight qualifier. No, then.
12 pounds of watermelon is about 11 pounds of water, so about a gallon and a third.
That’s a lot of water. Would it fall afoul of liquid and semi-liguid being excluded? Does jello count since it is also water suspended in a solid matrix?
If I had to guess, I’m sure that I have eaten, in a six hour period of time a quantity of food that put in a pile would have been bigger than my head. But I’ve got no specifics to mention.
Well, I was starving after a lobster node setting so I made a 7 litre casserole of hunter’s chicken stew. I ate it all between 6PM and midnight, though admittedly not in one sitting. I also had some garlic bread and three pints of beer.
Yeah, I wasn’t in any shape to actually go fetch the lobster nodes the morning after.
