WARNING: what this BBC TV presenter did is disturbing. 

Greg Foot undertook the nauseating experiment for his YouTube channel BritLab.

Mr Foot had chucks of flesh removed from his thigh in a graphic operation and then took them to a laboratory in Nottingham. 

There scientists used the sample to recreate the smell of his flesh and later he took the reconstituted sample and mixed it into a patty which he ate. 

"It's pretty good, beefy but lamby," Mr Foot said.
