Thousands of people are taking part in Christian Aid's Live Below the Line campaign this week.
The campaign challenges people to survive on just £1 a day for all their food and drink across five days.
Christian Aid hopes the campaign will raise more awareness and funds for people living in poverty.
The campaign has now reached Nigeria, with Christian Aid’s country staff signing up for the sponsored challenge.
Noel Bewarang, 47, Director of Christian Aid partner the Centre for Gospel Health and Development, is taking part.
He hopes to gain an insight into the lives of the people he works for.
"I am doing Live Below the Line because although I can claim to know what the poor go through, I do not feel what they feel," he said.
"Most of the time I get what I want and eat what I want to eat but I really want to experience what it means to desire something like food and not get it."
"I hope that doing this challenge will help us to appreciate the fact that the way we live affects the quality of life of others. It is often said that there is enough for everyone on the planet but some have more than enough while others merely exist living hand to mouth."
Mr Bewarang is being joined in the challenge by his wife and two children. They plan to eat mainly noodles and vegetable soup throughout the week.
He said: " We have budgeted to buy noodles, some vegetables and maize which is quite cheap and hope to make a pot of soup that will last the week.
"My kids could eat noodles forever. It will be exciting to share our experiences throughout the week and I hope this will really inspire us to change the way we live."
