Have you eaten Americanized "Chinese" food? I eat it every on every last Tuesday of the month. I order two meals for myself every time, because without fail, I will be hungry again within less than 2 hours. Yesterday (4/28/2026), I had a pint of General Tso's Chicken with a pint of beef lo mein. That's an entire quart of food. If I ate a quart of spag bol for my lunch, I'd be done for the night. I'd be asleep. But after my big ol' "Chinese" lunch, I was hungry ~90 minutes later, so I ate my pint of Szechuan Chicken and my pint of pork fried rice. Wonton soup was also involved. Yes, I added the fried noodles.

And even after that, I got a large pizza (pepperoni, pineapple, and extra cheese) at 10:30pm, just to cover the late night munchies. I only ate 4 slices out of 8, so I had some left for breakfast today. The stuff we sell as "Chinese food" in the USA is not very filling.

YMMV, I am a large man, and I am very active. I'm 6'4", I lift weights, and I run 6 miles a day. My TDEE is ~3800 calories. If you're one of those folks who only need 1200-1600 calories a day, a simple lunch from the "Chinese" spot would be a lot of food for you. My wife is small, and she can easily live off 1600-1800 calories a day. Our gf is tiny and lives off of 1200 calories a day most days. A "splurge" day for her is 1500-1600 calories.
