This was developed more than 30 years ago by the CISRO here in Australia. What they did is made antibodies against fat cells surface proteins. When injected into an animal the animal lost the fat cells all over their body if injected into a vein and just locally if inject into fat tissue.
I don’t know whatever came of the technology, but I always thought it would be very popular if applied to humans.
Yes this is what I thought too. I have no idea why it never was developed for humans - the original idea was to use it to make lean meat. Done with monoclonals and careful dose escalation it would be a huge hit.
