Pupil Johnnie Leather swapped his normal meals for Plumpy Nuts protein paste for 24 hours to raise money for charity.
13-year-old Johnnie, who attends Bedford Modern School, was the youngest person in the county and one of just four children to do the challenge that saw him eat just four sachets of protein paste and drink only water for one day to raise funds for Merlin UK.
The charity works with children in Africa ensuring starving children have the food they need to survive.
Plumpy Nuts are sachets of protein paste, packed with calories and vitamins, and given to severely malnourished children in East Africa.
Johnnie said: “£50 saves one child and as I am one of four children my target is to raise at least £200 as that’s like saving me and my sisters.
“My mum heard about the charity challenge on Twitter and I thought it would be good to see what it was like to eat the same thing as some of the children in East Africa.
I hope that by taking part in the ‘Plumpy Nut Challenge’ I will help raise awareness and also encourage others to get involved in fundraising for charity.”
And before the challenge Johnnie also received a good luck message from actor Hugh Bonneville, who is the patron of the charity.
He added: “It was really tough especially no snacks after school and not being able to eat tea with the rest of my family but knowing it was for such a good cause and raising so much money kept me going.”
