The invention provides an optical weight-losing, slimming and lipid-reducing hula hoop. Multiple groups of red light LEDs and/or laser tubes with the wavelengths ranging from 600nm to 30000nm are arranged on the inner side of a hula hoop. The optical weight-losing, slimming and lipid-reducing hula hoop further comprises a power source arranged on the hula hoop, and the power source supplies power for the red LEDs and/or the laser tubes. The optical weight-losing, slimming and lipid-reducing hula hoop has the advantages that according to mechanical energy generated during movement of a human body, solar energy is converted into electric energy, the electric energy or a dry battery and the like drives the LEDs with the special optical wavelengths to illuminate and generate infrared light to match with the movement of the human body, lipid of the human body is scattered and decomposed effectively, lymph is dredged to expel toxin rapidly, and accordingly effects of losing weight, slimming and body building of the human body are realized.
