Fitness fanatics can now tone up as they eat thanks to the launch of a bizarre new cutlery set.

The Eat Fit Cutlery set attaches dumbbells to a knife and fork, and saves the heaviest for the dessert spoon. The knife and fork weigh one kilogram each, and the spoon two kilograms.

Eat Fit Cutlery, which costs about $90 for a three-piece set, is aimed at “gluttons in need of a workout”.

A spokesperson for Firefox, which develops the products, says the cutlery and dumbbell mix is designed “for fitness fans with a sense of humour”.

While this product is designed to be tongue-in-cheek, it does highlight how far people will go to keep their bodies in fine form.

Why not come up with your own concept for healthy eating?

You could introduce ready-made meals for fitness fanatics to eat on the go, or a notification when people have consumed a certain number of calories.
