I had to reconfigure my entire life around it. I kept barely enough food in the house to meet my calorie target for the week. I once fell asleep while driving home from work and ran off the road because my blood sugar was so low. I spent 9 hours a week doing intense exercise and pretty much any time I wasn't doing that or working I was just sleeping. I basically had to have no social life, because socialization around here pretty much mandates large quantities of food.
Is something physically wrong with me? Probably, but good luck getting an American doctor to give a flying fuck. My thyroid stopped working when I was a child and it went undiagnosed for two years because doctors just keep telling my mother I was lazy. Ultimately a toll booth attendant diagnosed it because her dog had similar symptoms and my mother had to go full Karen to get the simple blood test to happen. American physicians are fucking useless.
Even treated, to this day I have to eat well under the caloric requirement that I "should" be eating and constantly feel like shit in order to lose weight, which makes me perform worse at work and apparently require 3-4 hours extra sleep every day.
I can guarantee you "willpower" people aren't doing that. Your body isn't fucked up and constantly demanding more calories than you need, so it comes easy to you and you probably just take any excuse to feel like you are better than other people.
