The first winner of Mr Gay UK stabbed a man to death before cutting a piece of flesh from his thigh, cooking it and trying to eat it, a court has heard.
Anthony Morley, 36, of Bexley Avenue, Leeds, then walked to a nearby takeaway and told staff he had killed someone, Leeds Crown Court was told.
Mr Morley, who worked as a chef, denies murdering 33-year-old Damian Oldfield.
The jury heard pieces of cooked human flesh were found in his kitchen and in a bin bag.
Opening the case for the prosecution, Andrew Stubbs QC told the jury that the two men had been involved in some kind of relationship in the past and that Mr Morley was troubled by his sexuality.
Mr Stubbs said the two men arranged to meet in Leeds on 23 April this year and later went back to Morley's house, where the defendant prepared a meal for them both before the pair went upstairs to his bedroom.
The prosecution claim the men had sex in the bedroom before Mr Morley attacked Mr Oldfield, cutting his throat and stabbing him numerous times.
Chef accused of cannibalism
After the attack, the court was told, Mr Morley walked a short distance to a takeaway wearing just a white dressing gown and flip flops.
"He walked in and said, 'I've killed someone, call the police'," Mr Stubbs said.
Robert Smith QC, defending, told the court that Mr Morley did kill Mr Oldfield, who was also from Leeds.
Mr Smith said Mr Morley was at least guilty of manslaughter but said the issue in the trial would be over provocation or abnormality of the mind.
