regular everyday lunch was like that (example):
-lunch started early after huge cooked breakfast; whole school lunch and ""snack" before i got home from school
-huge bowl of cow soup
-huge salad (tat salat alone would be healthy portion multiplied by 3 or 4.. of food for me as child/young teenager it was for example salat, corn, cabage, carrots, two or three normal luch portions of meat, 2 or 3 sorts of cheese, rich dressing, mayo, bread cubes, eggplant, two or three eggs…)
-half kg cooked pasta with 1/4kg bolognese sauce. that part of meal was ussually when i started feeling ready for stomach explosion and started crying.
-5 up to 10 pancakes with jam. (they decided those thing on my "behaviour" – that was all made up. i never actually did those thing. it was mostly about favorizing my sister; if she did anything wrong, they were in "that" mood, and i had to stuff my face MORE. i literally begged her to behave well many times. she didnt give a fuck when behaving.. but when i sat there, she begged them to let me off the table and cried. she was 0-6 years old at that time) i had jam. if sister was good that day, i was allowed to eat pancakes with chocolate which i loved. but it was exactly same painful, eating them either way. that was the part i either vomited on plate/run to toilet (they would ussually hold me still on chair not to do that and i had no option but vomit on food i knew i will still here to eat…) pancakes were awfuly often on menu.
-homemade dessert/dessert (half liter of pudding/1/4 liter of ice cream with waffels/whole plate full of brownies/even a bowl of cereal…) with cocoa/milk/hot chocolate
-at least two pieces of different fruit. just to be sure, you know, not to get malnourished. if i "behaved well at lunch which means i didnt vomit or cry too much and i was able to eat everything withing lets say 90 minutes" (which was rarely; i got those portions when i was already full from my previous meal), i was allowed to wait for half hour up to hour to eat the fruits.

my 100kg 40yrs stepfather's portions were a quarter of mine, and i was a child.. i got 2 hours to digest this before dinner, which was almost the same size, slightly smaller. needless to say i had to eat whole dinner, even if i didnt fiinish the luch yet. so i sat there with two plates long into the night and crying until sneaking to bed to cry /cut myself to sleep. between meals, if at table, i wasnt allowed to leave table for a second. if not at table, it they "guarded" the bathrooom, even watched me showering and pooping (oh i wasnt alloweed to shave btw until like 17 but i did on secret at school or smth at summer), because they got that weird idea in their sick heads that i fucking VOMIT ON MY FOOD I KNOW I HAVE TO EAT ON PURPOSE TO LOSE WEIGHT, which they accused me for years before i actually started doing it…and i KNOW FOR SURE that i do it because, if i was alone for some time, never more than 10 min until i moved out,, i had no other option but to pugre the food, because it made the dinner A LOT easier. if you never been forced to eat familysized lunch, you probably have no idea what kind of pain that brings. it's awful. it's like you are exploding, and being at that same time ripped apart. and i always had to do my best not to throw it up which was hard, because i was NOT ALLOWED TO… it's tremendous pain. no one should experience it. no one. not a child, not an adult. i was literally swallowing my vomit coming to my mouth until i couldnt hold it down anymore… then i would try to run to toilet at last moment, try all the sides of table in life but they got me and hold me still on my chair… i would vomit on my food, get slapped twice or trice for that, and forced to immidiately eat the food under the vomit because "now i can easily finish it now that my stomach is empty and i dont want to because i'm anorexic"
i have absplutely no idea where they got idea of me "being anorexic because i physycly cant eat amount of food that whole family together would have too much" or me "vomiting on my own fucking food because i cant hold that much down because i'm trying to lose weight", but they succesfully made those things really happen to me, being anorexic and bulimic, diagnosed with anorexia due to my low weight. not to mention sleep disorders, depression, anxiety, panic (i mean physycal panic, not like worrying about what to fucking wear)
