The British chef (pictured) is likely to focus on the global fight against obesity and the need to educate young people to make better food choices.
Oliver says: "When I was approached by One Young World to address the summit, I knew that it would be one of the toughest speeches I would ever give. These 1,200 delegates, all under 27, come from more than 170 different countries and they're the leaders and decision-makers of tomorrow.
"These guys don't care about formalities or protocol - they want an insight on the global obesity epidemic. I hope that everyone leaves the room with a sense of urgency that action needs to be taken. Now."
It will be Oliver's first public speech since accepting the innovation-rewarding TED Prize in February last year. He also spoke about nutrition at the time.
Other counsellors at One Young World include Archbishop Desmond Tutu, internet activist Wael Ghonim and a string of chief executives such as Paul Polman, of multinational company Unilever, and Jean-Paul Agon, of L'Oreal, the world's largest cosmetics manufacturer. Young Post editor Susan Ramsay will also be there, reporting on the event.
The summit brings together some of the brightest minds to ensure that their concerns and solutions are heard.
The One Young World inaugural summit was held in London last year, drawing 823 young leaders from 112 countries. It focuses on six key resolutions that aim to address the world's problems.
