How the fuck do people get so fat? How can you eat so much food? I just don't get it

My metabolism turned to shit once I turned 20. I would always eat very little, skip breakfasts and still wouldn't go under 70kgs even though I was basically eating 1400 calories a day. Then I began lifting and doing cardio, my metabolism increased and I ate double than before and am skinny as fuck.
I understand my case is an exception though, most fatties are lazy-ass gluttons

I am fat because I drink, I hardly eat at all but i drink at least a twelve pack and night plus vodka is a shit ton of calories.

Sedentary lifestyle + eating McDonalds everyday for lunch.

eat less then lol

I also don't understand, if I eat more than ~250 grams of food I start feeling stuffed and tired.

There's sugar and HFCS everywhere here, and portions are huge.

it doesn't happen in a day. for me it's inability to handle stress. cope with sweets.
bullshit, go to Yas Forums

Food is good my man, i was always a bit chubby.
I literally cannot conceive a man cannot "eat enough" in the 21th century.

all lanklets i know eat atleast twice as much as me. if i go out with friends for food and beer, they all stuff down steak after steak and top it up with beer. i have like one steak and i then i drink wine not to feel full. even then i get so stuffed i get dizzy and my hole night out is ruined, they top it up with two rounds of dessert and need kebab on their way home a couple hours later. metabolsm is definetly a thing. my mother says my lungs must have the ability to draw food out of the air.
