The single man, in his 40s, admitted to previously having an interest in sado-masochistic sex and used to visit a Fifty Shades Of Grey-style fetish club with an ex-partner.
He has accused North Yorkshire Police of "sour grapes" after his acquittal for rape at a retrial, having spent 14 months on remand.
The man is currently subject to a Sexual Risk Order which the force successfully applied for at a magistrates court.
The order, which police will ask to be made permanent at a hearing in August, includes a condition requiring him to inform police 24 hours before he has sex with a new partner.
In a statement, the man said: "I intend to commence hunger strike in protest over the SRO to which I am subject.
"I protest that even though a jury found me unanimously not guilty, after nearly two years I still find myself being punished for a crime that never happened.
"I protest to being subject to an order that is unlawful in almost every syllable, is unjustified and is so extreme as to be utterly unlivable.
"Home Office guidelines clearly explain the types of behaviour that SROs are designed to prevent, and none of it applies in any way to me.
"The law has been misapplied deliberately by North Yorkshire Police out of sour grapes over being shown to be prejudicial and incompetent in their investigation of the original complaint against me."
The man denies having any criminal convictions, "not even a parking ticket", when he spoke to reporters at York Magistrates' Court earlier this month.
He said at the previous hearing: "It puts an end to your life.
"I had more freedom in prison.
"The severity of the restrictions exceed what convicted criminals would get on a Sexual Offence Prevention Order."
He said there was "no prospect" of a relationship at the moment.
He said: "Can you imagine, 24 hours before sex? Come on."
