Researchers in Colorado think python blood may be the next weightloss craze

This may have been bigger news a year or two ago before the boom of GLP-1’s, but if you’re still looking to lose a few pounds here ya go…

Scientists at Stanford and the University of Colorado say a molecule in python blood could pave the way for the next generation of obesity drugs.

Pythons tend to eat a “heavy meal”…like an antelope…then go for months without eating. It’s thanks to one molecule. It’s called pTOS and it spikes after pythons eat a large meal. The researchers say when they gave it to obese mice, they lost weight.

While it sounds creepy, snake venom is already used in some blood pressure and anti-clotting drugs.
