eating more to lose more

Options
It's a phrase I'm sceptical of but now that I'm 2 weeks from my "used to be" goal-date and am no longer losing (and my weighing etc is accurate) on netting 1000 calories ot less, who has had success with this?

I'm talking that I've been doing 1000 calories or less for 2-3 years not 2-3 weeks and I don't think I should be dropping lower...

Did you gradually build up? Or jump straight up 200 or so to see results?

Did anyone do it and not see results and get them in another way?

Thanks in advance :)
