The trick is to put half in one end, and the rest in the other.

is it, though?

a stomach can stretch upto 4 litres in capacity when pushed (one source). that's 4000cm³ (or 244 cubic inches).

to fill that capacity, the volume of a pizza needs to be 4000cm³ or 244 inch³.

take πr²h = 4000 for thin crust pizzas, if we assume the average height of pizza and toppings as 1cm, our equation simplifies to πr² = 4000; which gives the radius of the pizza as around 36 cms -- or a diameter of 72 cms (or 28").

if we take a thicker pizza of an average crust thickness of 1", then our equation for square inches simplifies to πr² = 244. which gives us a radius of about 9" or a diameter of 18".

since most pizzas top out at 12"-14" diameter (thin and thick crust volume varying between 700cm³ to 2600cm³), if anything, we're nowhere near achieving our full potential!

Every pizza is a personal pizza if you just believe in yourself.

When I was younger, I could eat superhuman amounts of food and not gain an ounce (I was even accused of having anorexia by strangers because I was so thin).

Now, if I even think about one serving of ice cream, I gain ten pounds. Oh shit, I’ve done it. Back to the treadmill, I guess.

As one of those that easily destroy an XL pizza in one go... why is that terrifying?

I Mean, overall I don't eat all that much... I never eat breakfast and very rarely eat lunch, so one or two meals a day for me (historically a very active person) has to be large to make up for the times I don't have time (or want) to stop and eat. So it takes at least a large pizza or like two boxes of Mac & cheese to even come close to refilling my fuel tank.

When I was in junior high, a local pizza/burger/Chinese (if it was food, chances are they made it) place had a Safe Cracker pinball machine that would give you a token every 1 million points which you could redeem for a large, one topping pizza.

I would very often go there with no more than a dollar and end up getting 2 free pizzas and eat them all to myself because I was really good at that pinball machine and also had a bottomless pit in my stomach.

These days, I think less about the pizza and more about how I would love to have a Safe Cracker pinball table.

I'm feeling very attacked right now.

When I was 8 years old, my sister ordered an XL pizza from papa johns. And I said "Ok......but what are YOU having?" She laughed it off as me saying I'd eat the whole thing myself. I saw no joke. So I made her order a second pizza for herself. She got a small. And when I was done with my pizza, I ate half of her pizza. She then accused me of playing some prank on her. She searched her apartment up and down claiming I was hiding the pizza somewhere. I was like "YOU WATCHED ME EAT MOST OF IT!!!"

My stomach did not have an "off" button. At least not until decades later when they removed 2/3rds of my colon. Now I can eat something small to medium sized and feel like I'm full.

But back then? I honestly think if you'd have put 10 XL pizzas in front of me, I'd have eaten them all if I liked the toppings. Then asked for snacks later.

I've been on Adderall since I was 9 and my relationship with food is basically waking up hungry, taking some pills, and then being hungry but having absolutely no impetus to act on it... And 12 hours after waking up everything wears off and it's suddenly 'food horny' for lack of better word. Profoundly, ravenously hungry.

I've basically been training my whole life to saunter into a pizza place and order a 16" pizza and eat the whole thing in 15 minutes.

Professional competitive eaters are nuts tho, this pizza place near me has a challenge to eat a 16" specialty pizza, I did it for shits and giggles after work one day in like 20 minutes, but on their wall of finishers, a professional eater stopped in and ate the whole damn thing in 2 minutes and 49 seconds, that's terrifying

If the diameter is not at least 40cm, it's not a pizza for me.

I wasn't the most popular growing up and I remember becoming popular and developing a larger friends group in late high school. Above all, I remember going out for pizza when I was 17. At home, we always shared a small (frozen or delivery or restaurant) pizza - me, my sister, and my mom. Eating pizza meant having a slice or two for dinner (with salad, there was always salad). So this also always meant prior discussions on the toppings. Therefore, going out with new friends, I was highly confused why no one was really engaging in my question about what kind of toppings they want, everyone was just stating what they want and gonna get and I was hella confused. When it occurred to me that everyone was going to order a whole pizza for themselves I couldn't believe it. I don't remember what happened next, I only remember the horrible realization that everyone is going to buy a pizza and eat this food, that to me was absolutely meant to be shared, by themselves like psychopaths, a whole family meal, for each person. And that this was the normal way to do it. As I said, I don't know what happened next, but I don't really like pizza to this day - maybe something happened that day, I don't know.

Thank God I found a spouse who likes to share a small pizza and can't have more than 2-3 slices tops either.

Watch "Beard meets Food" on YT and learn.

Any pizza is a personal pizza with enough determination

Gonna have to disagree with ya there, bud.

Given how obese americans are, I'm kind of surprised you've never seen anyone do it. In my 20s, I could crush an XL and ask for seconds. I still eat a large by myself and I'm not an especially big person.

I feel personally attacked

How many inches constitutes a "large" nowadays?

I don't know what this means and I am to afraid to ask

Dominos used to have a large pizza for $5 and a bottle of Boone's Farm Strawberry Hill was 1.99

Is it though?

Unless you're talking party pizza, it's pretty much designed to be eaten by a single person.

If you weigh 200lb and eat 2lb of pizza you are approximately 1% pizza.

My hunger response is all messed up; exceedingly slow to satiation, hungry almost immediately after. I'm basically always hungry even sometimes getting hunger pangs that are physically painful and come with nausea; not eating for even around like 12-16 hours would sometimes cause me to gag and to feel like I needed to throw up. Changing some dietary things has helped, but I'm still almost always hungry and never stay full long.

Even as little as a year ago, I could put away a large pizza, some ice cream, a meal from McD's, and more in one day and still be hungry. I probably still could if not for ending up needing to cut gluten (one of the things that seems to have helped). By BMI I'm right on the border between overweight and obese and dropping (I will probably be just 'overweight' in mid-Feb 2025 or so).
