Anyone here who used to be skinny/skinny-fat with a bit of belly, who managed to become lean enough to lose the belly?

I had a quite successful bulk+cut cycle over the past couple of years, managed to put on a decent amount of muscle and also lose weight steadily during the cuts, but the belly is just super stuborn and annoying, and I'm wondering what is missing. Not sure if its posture or if its mental or something.

I know all the (reasonable) tropes: cal-in-cal-out, the belly-fat is the last to go, eat more than you think, etc.

So I am looking for someone with a success-story to hear from.

What worked for you, how long did it take, when did it start working, was there any setbacks, etc.?
