Abstract: The invention relates to a device for providing a breathing gas, in particular to a device for conditioning a breathing gas for stimulating weight reduction of a breathing creature. The invention provides a device for providing a breathing gas, comprising gas supply means and gas conditioning means. The device provides a breathing creature with a breathing gas which is conditioned by adding particles comprising a frozen fluid to the breathing gas. When the breathing creature inhales the breathing gas, his body comes into contact with the gas and the particles comprising the frozen fluid. The breathing gas and the particles will be warmed by the body of the creature, preferably to a temperature at which the frozen fluid starts to melt. The warming of the particles and the breathing gas by the body of the breathing creature requires energy, and therefore stimulates the metabolism of a breathing creature, promoting fat burning and inducing weight reduction.
