Last year, my mother decided to go on a diet. She wanted to lose a few centimetres of waist to be able to wear her new jeans. After 6 months of an intense diet, she didn’t see anything changed, and she didn’t know if it really worked out. So in the night, I had an idea. Why didn't anybody think of it? I was going to invent the belt-centimetres. That idea came to me when I saw my mother measuring her waist . Why not measuring oneself by wearing this belt ? That’s why I invented the belt-centimetres. The materials used are simple: a belt with digital numbers indicating the number of centimeters. This invention is for all the people who are on a diet, or for people who exercise to get thinner. Goodbye the centimetres with no practice, and hello tothe belt-centimetres! The belt-centimetre costs 5€.
