Fifty-one percent of respondents to the tongue-in-cheek survey of 20,000 people, who live in North America but hail from countries with teams in the June 11-July 11 World Cup, said they would starve themselves for a week if that would bring victory to their national squad.
More than 40 percent offered to give up dating for a year, while seven percent said they would gladly give up their job to see their country win the title.
A further four percent were willing to give away a body part.
The survey was conducted by US-based international calling firm VIP Communications Inc (www.JoinVIP.com) ahead of the South African extravaganza featuring 32 nations.
It found that a majority of English respondents - 93 percent - would give up food for a week to see England win, while some 70 percent of Italians would give up their job for an Italian victory.
Americans were most willing to sacrifice their homes, while South Koreans were most ready to sacrifice their love life.
And the people least willing to make a sacrifice? The survey found that only 3 percent of Solvakians would give up anything to improve their country's chances of victory.
