Losing more than 20% of your body weight?

I’m aware that during trials MJ was shown to help people lose up to 20% of their body weight if on 15mg after 72 weeks.

Has anyone here lost more than 20% of their body weight while being on a lower dose than 15mg?

Just want to see how common it is, or if it is even possible.

ETA: I’m currently 14% down and have been on 5mg since late November. I’m thinking I will get past 20% also as that’s only another 10lbs (4.5kg). Thank you for all of the responses so far.
