Amanda Bynes is already turning heads with her weight loss — but don’t get it twisted, she’s not done yet!

Sources close to Amanda tell TMZ she’s dropped from 180 pounds down to 151 … and she’s aiming to lose another 30 to hit what she calls her dream body.

We’re told the weight’s come off strictly due to Ozempic — no hardcore gym grind — and because of the GLP-1 drug, she’s eating way less than before.

This has never been a secret transformation … Amanda’s been pretty open about the whole journey on social media … and clearly, it’s something that’s working for her.
