Marek Hoffmann, a Polish man, discovered a novel way to heat his home by using Lidl doughnuts instead of traditional wood. Frustrated by the exorbitant energy bills required to keep his house warm, Marek calculated that it would be more cost-efficient to use doughnuts, given their low price and caloric value. Each doughnut contains approximately 440 calories and costs around 2p, making them an unexpectedly viable heating source.

His unconventional experiment led him to use a total of 133 doughnuts to heat his home, prompting curious responses from his friends and family. Marek stated, ''I was just curious if it made any sense,'' indicating that this started as a personal experiment rather than a commercial venture. The theory behind his approach rests on the scientific principle that calories measure the energy content of food, which can also be interpreted as a source of heat.

This humorous yet practical approach highlights the lengths to which individuals may go to combat rising living costs. While it is unlikely that this method will become a mainstream solution for home heating, Marek's experiment underscores the challenges of energy affordability and the innovative thinking people employ to manage their expenses in the face of rising energy costs.
