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

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.

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!

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

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

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

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.

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

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 worked at a pizza buffet back in high school. There was a guy who would come in from time to time and eat 6 whole pizzas. He would wait for us to put a fresh pepperoni out then just dump the entire thing on his plate.

I feel personally attacked

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