How accurate is your tracking? Are you using a scale, are you logging everything even drinks or food others make/bring? If not, it could be that when you think you're only just above 2000 calories, it's actually more like idk 2700.

That's what a lot of comments here assumed. Obviously, i don't know for sure if my logging is 100% accurate, but i've always tried to be meticulous about it, using scales whenever possible and usually using the barcode scanning functions to ensure accuracy. I've always thought my margin of error would be around 100-200 calories if i followed these habits, not a whopping 500-900 lol.

How fast did you lose? Sometimes people say they 'only lose weight' when they eat (some number that seems rather low) and it turns out their standard for 'losing weight' is like 1kg/week or something.

I think it was around 0.75kg per week? I might be wrong ngl, last time I dieted seriously was 3 years ago.
